I will put the events in order and further explain what happens to gaseous exchange during exercise.
During exercise,
- Blood CO2 increases,
- Blood becomes more acidic-PH decreases below the set point,
- Brain stem detects PH change,
- Brain cell signals muscles in the diaphragm and rib cage,
- Breathing level increases,
- Amount of CO2 exhaled increases,
- Blood PH returns to the set point.
During exercise,the cells of the muscles respite more than when the body is at rest.Heart rate increases abd,more oxygen is used or required and more CO2 is exhaled.
The rate and depth of breathing increases and this is in a bid for the body to compensate by making sore that more oxygen is absorbed into the blood as well as remove more carbondioxide
When CO2 combines with water, carbonic acid is formed,this makes the blood to become acidic.
Therefore,when CO2 is present in the blood,it decreases the blood PH and an excess of it (PH less than 7.35) will result in Acidosis.

Cells use a molecule called (DNA / RNA / ATP / CMP) to store and release energy like a battery. The energy is stored in chemical bonds between (nucleotide / oxygen / phosphate / ribose) groups of the molecule, and the energy is released when the chemical bonds are broken.
Answers
Answer:
Cells use a molecule called ATP to store and release energy like a battery. The energy is stored in chemical bonds between phosphate groups of the molecule, and the energy is released when the chemical bonds are broken.
Explanation:
ATP (adenosine triphosphate) can be though of as a battery. It is also sometimes desribed as the energy currency of the cell. DNA and RNA are nucleic acids - the genetic information of the cell, and does not store and release energy. CMP is a nucleotide.
The energy found in ATP is found stored between phosphate groups of the molecule. When a phosphate group is released, it forms ADP (adenosine diphosphate)
Cells use a molecule called ATP to store and release energy. The energy is stored in chemical bonds between PHOSPHATE groups, and the energy is released when the chemical bonds are broken.
ATP is the energy coin of the cell whose hydrolysis is used to carry out many different metabolic functions (e.g., reproduction, differentiation, growth, etc).
ATP hydrolysis is a catabolic reaction, which provides releasable energy stored in the bonds between the second and third phosphate groups.
The molecule of ATP can transfer its energy to different molecules during many cellular processes such as, for example, DNA replication, active transport, muscle contraction, etc.
In conclusion, cells use a molecule called ATP to store and release energy. The energy is stored in chemical bonds between PHOSPHATE groups, and the energy is released when the chemical bonds are broken.

Describe the relationship of dissolved materials inside and outside a cell in isotonic, hypotonic,
and hypertonic solutions.
PLEASE HELP ASAP!! WILL MARK BRAINLIST TO FIRST WHO ANSWERS!
Answers
hypertonic is when blood cells shrivel under hot temperatures
isotonic is equilibrium between concentration of blood and salt
hypotonic is less concentration on outside compared to inside
Answer:
When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell. ... If placed in a hypotonic solution, a red blood cell will bloat up and may explode, while in a hypertonic solution, it will shrivel—making the cytoplasm dense and its contents concentrated—and may die.

Earth is currently in a state of climate change because average global temperatures are slowly but steadily increasing. If this trend continues, what changes would you expect to see in the cicada life cycle? Use information from the article to support your argument
Answers
Answer: Cicadas will emerge from underground earlier in the year. Based on current patterns, they emerge earlier in the south than in the north because it’s warmer in the south, so the soil warms sooner. If global temperatures increase around the world, cicadas will emerge from the ground in all areas earlier than expected.

All living cells are capable of replicating themselves and this is done via the process of cell division. However, the rate at which cell division occurs must be regulated.Due to series of reasons like mutation, cells can lose the ability to regulate their cell cycle leading to a proliferation in the rate of cell division.

"Enzymes are organic catalysts" refers to the fact that enzymes are an organic class of biological molecule that act as catalysts in chemical reactions.
Catalysts are compounds that speed up chemical reactions without being consumed or changed in any way. In living organisms, enzymes are essential for many biochemical processes, including the breakdown of food during digestion, the synthesis of molecules, and the facilitation of cellular processes. Enzymes help maintain vital biochemical processes, maintaining the fundamental activities of life, by reducing the activation energy required for a reaction.

Runners only have enough stored ATP in their muscle cells to run for about five seconds. Which answer correctly explains how the runner's body adjusts to the longer distance, for example, a marathon (42.1 km)?
Answers
Answer Options:
A: The runner's body will convert stored fat molecules into energy.
B: The runner's body will create the needed energy by breaking down proteins.
C: The runner's body will supply the needed energy by producing starch.
D: The runner's body will produce the energy by activating the Golgi apparatus.
Answer:
A: The runner's body will convert stored fat molecules into energy.
Explanation:
When the body needs energy to power cells, it uses ATP. ATP is generated by cellular respiration, which involves the breakdown of (usually) sugars by aerobic respiration.
If you exercise for a longer period such as during long distance running, your body will use more fat and less glucose in an attempt to conserve the limited glucose stores in case exercise intensity increases and oxygen availability is is reduced.
The runner's body will convert stored fat molecules into energy.
