geosphere burying organisms
hydrosphere respiration of marine life
biosphere photosynthesis atmosphere burning things
Answer:
This question is incomplete, the question is asking to match each activity with the sphere to which it adds carbon or CO2.
ANSWERS:
Geosphere = burying organisms
hydrosphere = respiration of marine life
biosphere = photosynthesis atmosphere = burning things
Explanation:
This question describes the types of spheres we have. The respective activities that occur in each sphere that adds CO2 or carbon are as follows:
- Geosphere: This refers to the solid part of the Earth. Dead organisms are buried in the geosphere (soil) where their carbon remains can be deposited.
- Hydrosphere: This constitutes all of the water bodies (sea, river, stream, ocean) on the Earth. When marine organisms respire in water, carbon dioxide (CO2) is released.
- Biosphere: A sphere consisting of all living things (plant, animal, microbes etc.) on Earth. Plants as a living organisms photosynthesize and make use of carbon dioxide to produce glucose, which stores in the plant.
Atmosphere: The gaseous component of the Earth. Burning substances release carbon based gases into the atmosphere.

In a study involving a cell-free translation system from coli, the polyribonucleotide AUGUUUUUUUUUUUU directs the synthesis of the oligopeptide fMet-Phe-Phe-Phe-Phe. In the presence of a new class of translation-targeting antibiotics that bind to the large ribosomal subunit, the ribosomal complex forms, the initiator tRNA binds the mRNA, the second tRNA enters the A site of the ribosome, but no peptide bonds form. Which of the following is a likely function of these new antibiotics?
a. Blocks peptidyl transferase activity
b. Inhibits tRNA aminoacyl synthetase function
c. Inhibits ribosomal translocation along the mRNA
d. Prevents anticodon base-pairing with the codon
e. Blocks binding of the Shine-Dalgarno box to the rRNA
Answer:
c. Inhibits ribosomal translocation along the mRNA.
Explanation:
Initiator tRNA is thought to bind directly to P-site of small ribosomal sub unit. These tRNA are positioned at P site and remain attached to tRNA located at this site. Initiation factor helps to mediate this event.
Eutrophication occurs when excess nutrients are supplied to a region, leading to an algae bloom and ultimately ______
A. Coral bleaching
B. Ocean deoxygenation
C. Ocean acidification
D. Overfishing
Answer:
The correct answer is - B. Ocean deoxygenation.
Explanation:
Eutrophication is the process in which a water body gets excessively rich in nutrients that leads to the algal growth or plankton growth in this region and covers the complete surface or most of the water body.
Due to this algal and plankton growth, there is a significant decrease in the concentration of the dissolved oxygen in water bodies that result in the incapability of supporting the lives found in it. The primary and main reason for this deoxygenation is eutrophication. Ocean deoxygenation is the reduction of the oxygen concentration of the oceans.

Haploid cells join to form an organism that has a complete set of chromosomes.
Explanation:
What would be most likely to happen if some of the proteins Ik one of the photo systems were to change shape due to a drop in cell pH?
A. A decrease in the formation of NADPH
B. An increase in the formation of NADP+
C. A decrease in chlorophyll production
D. An increase in sugar production
Answer:
Option A
Explanation:
If some proteins in one of the photosystems undergo change in their shape due to a drop in pH of cell, they will not perform their activity. Due to this, there will be a decrease in the formation of NADPH ( that is less reduction of NADP due to blockage in the transport of electron).Why is the frequency of natural disasters increasing?

If a person develops chronic lymphocytic leukemia, what leukocytes may be involved and how mature are they in the bloodstream? Common symptoms of all types of leukemia are caused not only by the poor functioning of leukocytes, but also by the loss of erythrocytes and platelets. These formed elements have a reduction in their number because the tissue that normally produces them is crowded out by the uncontrolled growth of the leukocyte-producing tissue. For each symptom below, state whether leukocytes, erythrocytes, or platelets are involved.
anemia
easy bleeding
repeated infections
enlarged lymph nodes
shortness of breath
excessive bruising
Answer:
The correct answer is -
anemia- erythrocytes
easy bleeding- platelets
Repeated infections - leucocytes
enlarged lymph nodes- leucocytes
shortness of breath- erythrocytes
excessive bruising- Platelets
Explanation:
Cancer of the lymphocytes is chronic lymphocytic leukemia (CLL). Lymphocytes are a type of white blood cell involved in the body's immune system.
Platelets are tiny blood cell fragments that help your body form clots to stop bleeding. The platelets then rush to the site of damage and form a plug, or clot, to repair the damage.
Erythrocytes are red blood cells that travel in the blood. They carry oxygen from the lungs to the body and bring carbon dioxide back to the lungs to be expelled.
Leucocytes- White blood cells (also called leukocytes or leucocytes and abbreviated as WBCs) are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders.
Describe what is happening in each of the phases of cellular division with what you observe from the photomicrographs in the lab instructions (describe and compare both).
Answer:
Interphase - There are 3 subphases called - G1 , S and G2 . In these subphases, DNA material is duplicated, and essential proteins for cell division are formed.
Prophase - the nuclear envelop and nucleolus disappears and condensed DNA forms chromosomes that are short in size.
Metaphase - the form of two sister chromatids are arranged in the middle of the metaphase/equatorial line. Two centrioles are found at two poles of the cell which initiate the formation of spindle fibers.
Anaphase - spindle fibers are formed and can be observed. These fibres attach with the kinetochore present in the centromere of chromosomes and these chromatids now start separated by pulling and pushing force of spindle fibers in opposite poles
Telophase - chromatids reach at destination pole and then nuclear envelop starts creating again in both poles. Nucleolus reappears and now in a cell two nucleus are found.
Type of symbiosis Suppose friendly ants fed on sugary droplets excreted from a caterpillar, but did nothing to help the caterpillar. Assuming that taking the sugar does not hurt the caterpillar, what type of symbiotic relationship is this
Answer:
Commensalism
Explanation:
All organisms in nature interact with other organisms in different ways. Symbiotic interactions involve a relationship between two or more organisms of different species in which one or all of them turn to be beneficiated by that relationship. These species create permanent mutual dependence.
Symbiotic interactions include:
• Amensalism refers to a biological relationship established between two organisms, in which one of them avoids the growth, development, or survival of the other one. In this interaction, one of the organisms seems to be strongly affected by the other one. Meanwhile, the other organism does not seem to be affected at all.
• Commensalism: In this case, the fitness of only one of the species seems to increase, while the other species is not affected at all, nor positively or negatively. The unaffected species might provide food or refuge to the other species, which is benefited.
• Parasitism: In this case, one of the species is beneficiated, while the other suffers a consequence, reducing its fitness. These interactions are mainly about nutrition, although there might be other benefits too. Some parasite species might coexist with their host, while some others might get them ill to the point of causing death.
• Mutualism: The interaction is favorable for both species. Their fitness increases with these interactions, although they do not need this relationship to survive. The degree of benefits might vary among species or might be equal.
-----------------------------------------------------------------------------------------------------------
The exposed symbiotic example is a commensalism case. The ant is benefited from taking the sugary droplets. Its fitness increases. But ants do not make any harm to the caterpillar. In fact, it has no effect on them at all, no possitive nor negative. The caterpillar´s fitness is not influenced by the ant.

Given the range of current speeds shown on the graph above, would deposition ever be possible for clay (0.001 mm) or silt (0.01mm) particles?
Answer yes or no and explain your answer.
Answer:
Yes.
Explanation:
Yes, deposition can be possible for clay (0.001 mm) and silt (0.01mm) particles when the agent that carry its load is absent in that region such as wind. Wind is the agent that moves clay and silt particles with it so if there is high wind in a specific region, no deposition will occur while on the other hand, those areas where wind is not present, deposition will definitely occurs so we can say that deposition depends on the presence and absence of wind.
Do you think that organisms of the same order will share a stronger evolutionary relationship than organisms that share only the same phylum? Explain your reasoning using the results of your investigation.
Answer:
In taxonomic, the organism is classified based on some similarities. ... But the organism with the same order should have the same phylum and class too since order is located below the phylum. That means the organism with the same order should have more similarities than the organism with the same phylum.Taxonomical classifications are done for organisms including plants, animals, microorganisms etc. It classifies, defines and scientifically names organisms.
According to the taxonomical classification the organisms are classified based on similarities and in order of the taxonomy, the organism should have the same phylum and class.
In taxonomy, the phylum is above the order in level and the phylum will have fewer similarities compared to the organism in order or class.
The organism of the same order will have a strong evolutionary relationship as compared to the organism with the same phylum.

Describe fluid exchange between capillaries and the interstitial fluid. Be sure to discuss the forces (pressure) that moves the fluid and the direction in which fluid moves. (4 points) In one to three sentences, describe the role of lymphatic system in this fluid exchange. (3 points) g
Answer:
Capillary exchange is the exchange of fluid from the capillaries into the interstitial fluid and vice versa. Diffusion, transcytosis, and bulk flow are three mechanisms that facilitate capillary exchange.
The blood plasma or interstitial fluid exerts a pressure of the fluid on the capillary walls known as Hydrostatic pressure. Osmotic pressure is a pressure exerted by proteins either in the blood plasma or interstitial fluid called oncotic pressure.
Lymphatic capillaries gather lymphatic fluid and regulate the pressure of interstitial fluid due to the forces of hydrostatic or oncotic pressure. An essential role of the lymphatic system is to return the fluid to the blood.
which specialized senses, do not rely on hair-like appearing cell structures or cilia to transduce stimuli?
Answer: Touch.
Explanation:
Cilia are short, mobile prolongations which contain a central structure made up of microtubules and proteins, enveloped by the cytosol and the plasma membrane. They are involved in cell movement, transport of materials, displacement of fluids, among others. Cilia are important for many biological processes, such as the senses of taste, hearing, smell, sight and balance.
For example, each taste bud of the tongue is made up of a set of cells, among which are the taste cells that have cilia that come into contact with the substances dissolved in the mouth by saliva. As for the sense of hearing, when there is a sound, the endolymph in the cochlea moves and this stimulates the cilia of the internal sensitive cells, which communicate with the acoustic nerve that informs the brain of what the sound is like. In the sense of smell, the receptors are the olfactory cilia of the olfactory neurons, which are located in the mucosa of the upper portion of the nostril, above the level of the superior concha. In the sense of vision, cones and rods are the two types of photoreceptor cells that capture light energy and convert it into electrical signals. They are highly specialized cells and can be differentiated into several regions: an outer segment, an inner segment containing the nucleus and a synaptic terminal. The outer segments are modified cilia and consist of flattened membranous sacs or disks. As for the balance system, the vestibular system consists of the utricle and the saccule, which are chamber-shaped organs filled with endolymph. The maculae of the saccule are located in a vertical plane and effectively capture the accelerations of the upward and downward movements of the head, and therefore of the gravitational forces. The hair cells of the maculae are responsible for transforming the mechanical energy produced by movement into nerve signals. The activity of these cells is determined by their morphofunctional polarization or ciliary organization, which is different in the utricle and in the saccule.
Thus, the only sense that does not depend on cilia to transmit stimuli is touch. The skin contains nerve endings, as well as glands, blood vessels and hair follicles. These nerve endings detect pain, touch, pressure and temperature.
Imprinting can be cell-type specific; for example, this region of chromosome 15 is ONLY imprinted in neurons and a few other specific cell types, but it is not imprinted in most cells in the body, such as bone, liver, and heart cells. Which of the following statements are true about a healthy individual without Prader-Willi or Angelman syndrome? ( Choose two answers)
a. Maternal and paternal copies of SNRPN are expressed at the same level in heart cells.
b. The maternal and paternal copies of UBE3A are differentially expressed in bone cells.
c. The maternal copy of SNRPN has DNA methylation at its promoter in liver cells.
d. Expression of the paternal copy of UBE3A is silenced in neurons.
Answer:
The correct answer is - A and D.
Explanation:
Genetic imprinting is DNA modifications that result in changing the expression but not the sequence. Factors That affect such changes present both within and outside the cell.
It is a result of the silencing of either maternal or paternal alleles in a pair. This occurs random and leads to phenomenon like X-inactivation. The mechanism involves methylation of the DNA to be silenced. paternal copy of UBE3A is silenced in neurons.
Describe the purpose of mitosis.
2. Describe what is happening in each stage and what each stage looks like:
Prophase
Prometaphase
Metaphase
Anaphase
Telophase
Cytokinesis
Answer:
To acquire growth and to replace worn out and defected cells.
Explanation:
The main purpose of mitosis is to acquire growth and to replace worn out and defected cells.
In prophase, the chromatin condenses which is present in the nucleus of the cell.
Prometaphase is the stage where the nuclear membrane breaks apart into numerous "membrane vesicles".
Metaphase is the phase where all the genetic material is condensing into chromosomes.
Anaphase is the stage in which chromosomes are pulled by the spindle fibers to opposite poles of the cell.
In Telophase, the cell is nearly dividing, and it starts to re-establish its normal structures as cytokinesis (division of the cell contents) takes place.
Cytokinesis is the process which divides the cytoplasm of a parental cell into two daughter cells.
