What does an equation that shows water and carbon dioxide combining to form glucose and oxygen represent
a)Krebs cycle
b)Cellular respiration
c)Photosynthesis
d)Fermentation
Answer:
c)Photosynthesis
Explanation:
In bacteria, plants, and other eukaryotic species, photosynthesis is a biochemical process that is important for energy production; here, chemical energy is produced in the form of glucose molecules from:
Water Carbon dioxideLight energy
During photosynthesis, inorganic carbon is fixed by plants into high-energy carbohydrates and oxygen as a waste product...
6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
Carbon Dioxide + Water + Light Glucose + Oxygen

Yasmine is asked to describe the structural organization of chloroplasts. She writes the following sentence:
"A chloroplast contains thylakoid stacks, called stroma, that are surrounded by fluid-filled grana."
Which change to the sentence is necessary to make the sentence accurate?
A. Replace "grana" with "chlorophyll."
B. Replace "stroma" with "chlorophyll."
C. Exchange the positions of "stroma" and "grana."
D. Exchange the positions of "thylakoid" and "stroma."
Answer:
C. Exchange the positions of "stroma" and "grana."
"A chloroplast contains thylakoid stacks, called grana, that are surrounded by fluid-filled stroma."
Explanation:
A dynamic biochemical process, photosynthesis, occurs within the chloroplasts of plants. Here, to form stable carbohydrates, light energy is transformed into chemical energy.
6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
Carbon Dioxide + Water + Light Glucose + Oxygen
Chloroplasts are tiny, highly-folded, membrane-bounded organelles containing enzymes, pigments and other molecules that mediate photosynthesis. In the stack of grana, pigments like chlorophyll, absorb light energy for the light-dependent reactions.

which description properly describes a step involved in cellular respiration? (4 points)
Glucose is created, then the energy gained is transferred to the energy molecule.
Carbon dioxide is combined with oxygen to make glucose.
Water is divided into carbon dioxide and glucose.
Oxygen is combined with the carbon atoms left from the glucose molecule.
Answer:
Oxygen is combined with the carbon atoms left from the glucose molecule.Explanation:
Plants are producers that make polysaccharides through the process of photosynthesis. These polysaccharides, are used to store chemical energy stably in their covalent bonds.
Mitochondria break down sugars in cellular respiration. Aerobic respiration for instance, breaks down glucose in the presence of oxygen, which produces carbon dioxide and water, while transferring energy to the molecule ADP, to produce ATP (adenosine triphosphate).
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy
Oxygen is the final electron acceptor, it combines with the leftover carbons in respiration resulting in the waste product [tex]CO_{2} \\[/tex].
Answer:
Oxygen is combined with the carbon atoms left from the glucose molecule.

Plentiful roaming space- increase - because they have more space they can live in.
Severe drought - decrease- because they wont have enough water
abundant food source - increase - Because they have enough food to sustain themselves
Habitat destruction - decrease - Because they won't have a place to live in
Elimination of predators - increase - Because there will be less animals hunting them for food.
Lack of competition - increase - Because they won't have to compete for food which will allow them to have more.
Disease outbreak - decrease - Because the disease will kill a lot of them and can potentially cause birth rates to go down

Check all that apply for Mitosis
daughter and parent cells have the same number of chromosomes
daughter cells have half the number of chromosomes as parents
divides once
divides twice
2 daughter cells
4 daughter cells
Answer:
With respect to mitosis it is true that:
Daughter and parent cells have the same number of chromosomes.Divides once.2 daughter cells.Explanation:
Mitosis is the process of cell division that occurs in somatic cells, resulting in two daughter cells identical to the original cell, that gave rise to them. This process occurs because of the need of organisms to grow, develop, regenerate and repair themselves.
Somatic cells are diploid cells —full chromosome charge— and the result of their mitotic division are diploid daughter cells. The process of mitosis occurs only once during each cell cycle.
The other options correspond to meiosis, where from one cell haploid daughter cells are obtained, two successive divisions occur - meiosis I and II, the final result being 4 cells.
Why are bacteria a necessary part of the nitrogen cycle?
Other living things cannot use atmospheric nitrogen.
Other living things cannot use the nitrogen in plants.
Bacteria are the main nitrogen reservoir.
Bacteria are the main nitrogen transpirators.
Answer: The answer is... (A) Other living things cannot use atmospheric nitrogen
Explanation:
Other living things cannot use the nitrogen in plants except bacteria which has the ability to use and convert nitrogen.
Role of bacteria in Nitrogen cycle
Atmospheric Nitrogen gas can't use by the plants directly but the bacteria are able to use the atmospheric nitrogen and convert it in available form to the plants.
The decomposers, soil bacteria and fungi break down proteins in dead organisms and animal wastes, releasing ammonium ions which can be converted to other nitrogen compounds which make the bacteria an important part of nitrogen cycle.
In conclusion, bacteria is the only organism which can use nitrogen.

what process has the effect of changing ploidy?
Answer:
Ploidy is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. For many organisms, especially plants and fungi, changes in ploidy level between generations are major drivers of speciation
Explanation:
Hope this helps.. this is something I got from a website. I didn't got the paste and the copy from someone else..

Meiosis and fertilization are cellular processes capable of changing the ploidy level.
The ploidy level refers to the number of sets of homologous chromosomes in a given cell type.Meiosis is a type of cell division that is capable of reducing the number of chromosomes in the parent cell and thus produces four (4) gametes or germ cells.These gametes contain half the normal (i.e., somatic) number of chromosomes. During fertilization, two gametes combine to re-establish the ploidy level, i.e., the normal chromosome number in somatic cells.Thus, fertilization can restore the ploidy level of the parents.In conclusion, meiosis and fertilization are cellular processes capable of changing the ploidy level.

Which of the following adds inorganic phosphorus to an ecosystem
Answer:
The largest reservoir of phosphorous is sedimentary rock.
Major sources of phosphorous to aquatic ecosystems are fertilizer runoff, sewage leaks, and industrial wastes.
Eccess phosphorous can lead to eutrophication
Explanation:
Phosphorus come from different sources such as aquatic ecosystems and fertilizers used for plants. When these substances containing phosphorus and those from industrial wastes find their way into water bodies, they tend to cause eutrophication, which is the natural enrichment of water bodies.
Also, it is known that a very small portion of phosphoric acid contribute to acid rain in the atmosphere.
