What is the difference between atomic number and atomic mass ?
Atomic number of an element is defined as total number of protons present in the nucleus, neutrons carry no net electrical charge, so it is the charge number of the nucleus.
atomic mass of an element can be defined as the atomic weight is measured total mass of an element’s atom, the total number of neutrons and protons in the nucleus of an atom.
Both Atomic mass and an atomic number of elements are closely related if atomic number is high, then the atomic mass is also said to be high.

Nancy is explaining why chlorophyll is classified as a plant pigment and how it is useful in photosynthesis. Which property of chlorophyll would be most appropriate for her to cite?
A. chlorophyll's ability to absorb light
B. chlorophyll's green color
C. chlorophyll's presence in chloroplasts
D. chlorophyll's reactivity with oxygen
Answer:
A. chlorophyll's ability to absorb light
Explanation:
Within the chloroplasts of plants, a complex biochemical mechanism, photosynthesis, takes place. Here, light energy is converted into chemical energy in the form of stable carbohydrates.
6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
Carbon Dioxide + Water + Light Glucose + Oxygen
In the chloroplast, the light-dependent and light-independent reactions in which sugars are formed occur. In the light reaction that stimulates photosystems, pigments such as chlorophyll absorb light energy at specific wavelengths.
Specifically, chlorophyll then forms photosystem complexes (PS I & PSII) with proteins- these absorb and transfer light electrons etc to other downstream reactions like photolysis and the electron transport chain.

How do fish increase lake carbon dioxide levels?
Answer:
The primary sources of carbon dioxide in fish ponds are derived from respiration by fish and the microscopic plants and animals that com- prise the fish pond biota. Decomposition of organic matter is also a major source of carbon dioxide in fish ponds.
Fish can play a role in mitigating the accumulation of CO2 in aquatic ecosystems through Photosynthesis, Respiration, Organic Matter Decomposition, and Carbon Sequestration.
The carbon cycle in lakes and the role of fish within it:
1. Photosynthesis:
Aquatic plants, including algae and submerged vegetation, undergo photosynthesis, which involves using sunlight, carbon dioxide, and water to produce oxygen and organic carbon compounds. This process helps to remove CO2 from the water.2. Respiration:
Fish and other aquatic organisms respire, consuming oxygen and releasing CO2 as a byproduct. However, the amount of CO2 produced by respiration is typically balanced by the oxygen produced through photosynthesis.3. Organic Matter Decomposition:
When plants and animals die in the lake, their organic matter sinks to the bottom, where it is decomposed by bacteria and other microorganisms. This decomposition process consumes oxygen and releases CO2.4. Carbon Sequestration:
Some of the organic carbon compounds produced by photosynthesis can be stored in the lake sediment, effectively sequestering carbon for extended periods.Thus, through photosynthesis, respiration, the breakdown of organic matter, and carbon sequestration, fish can mitigate the accumulation of CO2 in aquatic environments.

Plants grown from runners and leaf cuttings have the same traits as the parent plant. Plants grown from seeds can vary from the parent plants in many ways. Why can this happen?
Explanation:
Plants produced from asexual reproduction are the result of mitosis, so they are genetically identical.
Asexual reproduction produces plants that are genetically identical because they are the result of mitosis.
What is asexual reproduction?Asexual reproduction is a type of reproduction that does not involve gamete fusion or chromosome number changes.
Asexually reproduced offspring from either unicellular or multicellular organisms inherit the entire set of genes from their single parent.
Asexual reproduction is also possible in yeast, fungi, plants, and bacteria. Yeast most commonly reproduce by budding.
Plants and fungi reproduce asexually via spores. Plants can indeed procreate asexually through vegetative propagation.
Asexual reproduction is significant because it allows for a rapid and significant increase in the number of individuals.
Many weeds and invasive species, for example, thrive in part due to their high capacity for vegetative reproduction.
Thus, the plants grown by seeds will have genetic variation due to meiosis in the cells. The runners will be identical to the parents as they will undergo asexual reproduction.

Based on your knowledge of on-site centralired storage of nuclear waste, what do you feel is the most appropriate long-term solutionShould radioactive spent fuel roda be moved to and stored Yucca Mountain? Defend your decision using evidence.
Answer:
Yes
Explanation:
Because
The Yucca Mountain repository is the proposed spent nuclear fuel (SNF) and high-level radioactive waste (HLW) repository where both types of radioactive waste could be disposed. If constructed, it would use a tunnel complex approximately 1000 feet below the top of Yucca Mountain and about 1000 feet above the aquifer underlying the repository. The basic idea of geologic disposal is to place carefully packaged radioactive materials in tunnels deep underground. To achieve this, the Yucca Mountain repository would utilize a mixture of natural and engineered barriers to isolate the waste from the surrounding environment.
It is statutorily limited to containing 70,000 metric tons of spent nuclear fuel and high-level waste, unless a second repository opens during its operational lifetime.

Explanation:
Cardiac output (flow) is determined by a pressure gradient and a resistance g. Which of these variables do you think contributes most to the very large increase in flow in this athlete?
Answer:
Cardiac output depends on the resistance mainly of the cardiac muscle walls.
Explanation:
The resistance of cardiac tissue also depends on its ability to distend in the sarcomero, that is, on the initial length of the contraction, the greater this, the greater the resistance, the greater the pumping efficiency, but the greater cardiac wear, this Situation occurs in people who are athletes or athletes since they have higher cardiac output but greater efficiency at the time of blood ejection, this is how they oxygenate the tissues better.

Explanation:
Why is this statement false? “The amount of carbon on our entire planet can increase or decrease depending on the fluctuations of the carbon cycle.”
Answer:
False because the carbon cycle is the process by which the carbon in the atmosphere of earth is exchanged and released in the biosphere and atmosphere of the earth. So basically, the amount of carbon is increased or decreased by the burning of fuels and not by the fluctuation of the carbon cycle.
The statement is false due to the fact that carbon does not decrease or increase due to the fluctuation of the carbon cycle.
Carbon flux in the carbon cycleThe level of carbon in the carbon cycle changes based on both natural and anthropogenic processes.
The natural processes include respiration, photosynthesis, and volcanic eruption while anthropogenic processes include the burning of fossil fuels, usage of emission technology, etc.
These processes lead to the addition and fixation of carbon from the cycle.
Thus, the cycle itself does not fluctuate but the level of carbon in the cycle.

B. Gene expression.
C. Polypeptide formation.
D. Transcription.
E. Translation.
Answer:
I think it is c have a good day
DNA, the RNA polymerase core enzyme, and the subunit are the first transcriptional components. mRNA, small and large ribosomal subunits, initiation and elongation factors, as well as tRNA, are all parts of the translation process. Thus, option D is correct.
What are the factor affecting the process of transcription?Proteins called transcription factors are involved in the process of turning DNA into RNA, or transcribed DNA.
A large variety of proteins—aside from RNA polymerase—called transcription factors start and control how genes are transcribed.
A gene's transcription is boosted by transcription factors that serve as activators. Reducers lessen transcribing.
An enhancer or silencer is a collection of transcription factor binding sites that can turn a gene on or off in a particular region of the body.
Therefore, Transcription is the process in which a strand of DNA is used as a template for the manufacture of a strand of pre-mRNA.

compare amd contrast the working of a kidneys and the artificial dialysis
Answer:
Based on these data, the blood presented weekly to an average dialysis system in centre-based care in ANZ = 325 ml/minute (i.e. 0.325 L) x 60 minutes x 5 hours x 3 treatments/week = 292.5 litres.
Scroll back for a moment and compare: two normal kidneys receive 10,000 litres of blood/week but a dialyser (the artificial kidney) in ANZ gets a measly 300 litres to play with, if it's lucky.
Yet, while that is clearly a stark difference, the comparison in the US is even starker!
The average calculation for a centre-based patient in the US is: 400 ml/minute (i.e. 0.4 L) x 60 minutes x 3.5 hours x 3 treatments/week = 252 litres; a low volume by ANZ standards, even after (my view) the higher access-damaging pump speeds used in the US have been factored in.
To compare these differences in another way, in ANZ only 292/10,000 = 2.93% of the blood presented in a week to two normal kidneys is presented for dialysis. In the US, it is even less: a paltry 2.52% (= 252/10,000).
What about home-based dialysis?
As a comparison, many home patients, especially in ANZ, perform up to 8-9 hours (mean = 8.5 hours) of overnight, while-asleep dialysis for an average of 5 nights/week. Most who undertake these schedules also run access-friendlier pump speeds of 225-250 ml/minute (mean = 0.2375 L). This provides 0.2375 x 60 x 8.5 x 5 = 605 litres/week for dialysis.
In the US, the most commonly used home profile seems to be a 400 ml/minute x 2 hour/treatment x 6 treatments/week program; this is the one that is most often delivered by the NxStage system, a low-flow system that, by its design, offers less efficient solute clearance compared to the ANZ-preferred single-pass systems. Thus, US home patients under this model present 0.4 L x 60 minutes x 2 hours x 6 treatments/week = 288 litres/week to a less efficient system. While this “short daily” home model clearly presents more blood for dialysis per week than does US centre-based practice, it is still less than the average ANZ centre-based volumes and compares even less favourably with the 600+ litres/week that are presented to the more efficient single-pass systems used by many/most ANZ home dialysis patients.
