How did photosynthesis and cellular respiration affect Earth's atmosphere?

Answers

Answer 1
Answer:

While cellularrespiration emits carbon dioxide into the environment, photosynthesis absorbs carbon dioxide.

What is cellular respiration?

Cellularrespiration is a sequence of chemical processes that decompose glucose to generateEnergy, which is then utilized as fuel to power a variety of reactions all through the body.

Cellular respiration consists of three major steps: glycolysis, the citric acid cycle, and oxidativephosphorylation.

The goal of cellular respiration is straightforward: it provides cells with the energy they require to function.

The greater the rate of photosynthesis relative to respiration, the faster ecosystems 'take in' atmospheric carbon.

As CO2 levels in the atmosphere rise due to humanactivity, causing global warming, the balance between photosynthesis and respiration in individual plants can shift.

Thus, this way, photosynthesis and cellularrespiration affect Earth's atmosphere.

Answer 2
Answer:

Answer: it is line A the other person is wrong.

Explanation:

The process of respiration produces energy for organisms by combining glucose with oxygen from the air. During cellular respiration, glucose and oxygen are changed into energy and carbon dioxide. Therefore, carbon dioxide is released into the atmosphere during the process of cellular respiration.

hope this helps

Scientists studying transcription in yeast (Saccharomyces cerevisiae) created an experimental strain thatproduced a modified RNA polymerase containing a single amino acid substitution. The scientists determinedthe maximum elongation rate during transcription with and without the modified RNA polymerase enzyme(Figure 1).The compound amanitin, which is commonly found in toxic mushrooms, is a specific RNA polymerase inhibitor.Amanitin binds to the RNA polymerase active site and inhibits transcription. In a second experiment, thescientists treated the wild-type and experimental strains of S. cerevisiae with a 40 ug/mL solution of amanitinand recorded the maximum elongation rate of the mRNA (Figure 2).

What is One difference between a fundamental niche and a realized niche

Answers

Fundamental niche is the job/role that one species can have in the environment .
The realized niche is the role of a species influenced by several factors in the environment.
Example:
The fundamental niche of Yellow Warblers is found in a spruce tree.
The realized niche of the Yellow warblers is when they are "forced" to share the spruce tree and remain in one particular area of the tree while other warbler species play defense different niches in other parts of the tree.

:v it is like :
•Fundamental niche: [yellow warbler] "I got my home, all for me..."
~new species arrive to the spruce tree~
•Realized niche: [yellow warbler] oh, shoot! I gotta stay in the upper part/move to the upper part as the others warbler "struggle" to get territory :v or they just choose their own . :v

A boy on a bicycle is resting at the top of a hill. Then, he rides his bicycle down the hill. Describe how the boy's potential and kinetic energy differ at the top, middle, and bottom of the hill.

Answers

At the top of the hill the boy has more potential energy. In the middle he's gaining kinetic energy but losing potential energy. At the bottom he has the most kinetic energy and no potential energy at all.

Which of the following best supports the statement that mitochondria are descendants of endosymbiotic bacteria-like cells?Mitochondria fossils are older than the oldest fossilized eukaryote.
Mitochondria can survive indefinitely when removed from a eukaryotic cell.
Mitochondria have their own set of DNA molecules.
Mitochondria can produce ATP molecules.

Answers

Mitochondria are descendants of endosymbiotic bacteria-like cells because D. Mitochondria can produce ATP molecules.

  • Mitochondria simply refer to the membrane-bound cell organelles that generate chemical energy that is used in the biochemical reactions of cells.

  • The theory of endosymbiosis simply explains that chloroplasts and mitochondria are descendants of ancient bacteria-like organisms.

  • It should also be noted that the chemical energy that is being produced by the mitochondria is stored in adenosine triphosphate (ATP) which is a small molecule where the chemical energy is stored.

In conclusion, the mitochondria perform most of the cellular oxidations that occur in animals. It's also useful in producing most of the ATP that can be found in cells.

I believe the statement would be that Mitochondria have their own set of DNA Molecules. This might promote the explanation that mitochondria are descendants of endosymbiotic bacteria like cells.

A researcher conducted an experiment to test whether exposure to high levels of UV radiation (that seen when ozone depletion is at its peak) harms human skin cells. He exposed human skin cells growing in Petri dishes to this level of UV radiation and determined the percentage of cells in each dish that died. He found that 30% of the cells died after 3 days of exposure to high UV radiation exposure. Why would it be unreasonable to conclude that this level of UV radiation exposure is harmful to these cells?

Answers

It be unreasonable to conclude that this level of UV radiation exposure is harmful to these cells because, There is no control group and we don't know how many cells would have died after 3 days with normal UV exposure.

Explanation:

The researcher in the given example shows the effect of UV radiation and its effects to the cells. He does not tell about the group that did not receive the UV radiation and their effects. A control group is very important in a research because it can be compared with the result obtained by some experiment effects. It is a group in an experiment in which the treatment is not given.

The results can be compared with the group under treatment with the group that did not undergo any treatment. Since, there is no control group in this experiment, we can not determine how many cells that were exposed to normal UV radiation  died after 3 days, it would be unreasonable for getting the conclusion of how harmful UV radiation exposure to these cells.
