A person who is exercising vigorously breathes more deeply and rapidly than someone who is resting. Give TWO reasons why this is necessary.
During physical exercise, more oxygen is used up and more carbon dioxide is produced leading to faster and deeper breathing.
Physical exercise is a state in which the muscles are flexed much vigorously leading to a faster heartbeat owing to a quicker rate of pumping of the blood by the heart.
There are two main reasons why a person engaging in physical exercise tends to breathe faster and more deeply;
The muscles tend to work harder during physical exercise hence more carbon dioxide is produced.The body uses up oxygen more quickly leading to a greater demand for oxygen and thus a faster and heavier breathing rate results.Learn more about physical exercise: https://brainly.com/question/1080637

the age of a woolly mammoth can be determined by examining what?
Answer:
examining the tusks, bones, teeth, (carbon levels in tissues depends)
Explanation:
Carbon-14 can be used to date the remains of dead organisms because all living things use carbon to build tissue.
The biological age of mammoths (also known as the "age at death") is usually estimated by comparison to correlations between the biological age and the wear stages of grinding teeth in extant elephants. As tusks grow, they continually incorporate ingested strontium (Sr), and the incremental record of strontium isotope ratios (87Sr/86Sr) in tusks and teeth can be used to investigate proboscidean movements
scrutinizing the bones, teeth, and tusks (carbon levels in tissues depends)
What are Mammoth?All living things need carbon to create tissue, making carbon-14 a useful tool for dating the remains of deceased species.
Mammoths' biological age, also known as the "age at death," is typically calculated by comparing it to correlations between that age and the phases of tooth wear in living elephants.
The incremental record of strontium isotope ratios (87Sr/86Sr) in tusks and teeth can be used to study proboscidean movements as tusks continuously integrate ingested strontium (Sr).

Which of the following correctly describes how the chemical equation for cellular respiration would differ from a chemical equation for photosynthesis?
Answer:
Uh not seeing an option but I hope this helps
The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O.

What is the process of double pump?
Answer:
Your heart is a single organ, but it acts as a double pump. The first pump carries oxygen-poor blood to your lungs, where it unloads carbon dioxide and picks up oxygen. ... The second pump delivers oxygen-rich blood to every part of your body. Blood needing more oxygen is sent back to the heart to begin the cycle again.
Explanation:
Explain the process of evolution by natural
selection.
Answer:
Natural selection is a process where organisms that are better adapted to an environment will survive and reproduce. This means that the advantageous alleles of this variant organism are passed on to offspring. Over many generations, the process of natural selection leads to evolution occurring.

21. Three different processes are occurring in the drawing below. Name each process and describe it.
The three different processes that are occurring in the above drawing are:
1. Process A: Diffusion.
2. Process B: Facilitated diffusion.
3. Process C: Active transport.
Cell transport refers to the movement of ions, molecules, or substances across the cell membrane, either into or out of the cells of a living organism.
From the above diagram, the three (3) different processes that are occurring are:
1. Process A: Diffusion.
Diffusion refers to the movement of gas molecules from a region of high concentration (top) to a region of lower concentration (bottom) until an equilibrium is attained or reached.2. Process B: Facilitated diffusion.
Facilitated diffusion refers to the movement of substances or gas molecules across a cell membrane from a region of high concentration (top) to a region of lower concentration (bottom), especially through the help of transport protein.3. Process C: Active transport.
Active transport involves the movement of substances across the cell membrane from a region of lower concentration to a region of higher concentration, against a concentration gradient and in the presence of oxygen.Read more: https://brainly.com/question/18646362

in an otherwise normal cell, what happens if one mistake is made during dna replication?
Answer:
Most mistakes are corrected, and if they are not, they may result in a mutation, defined as a permanent change in the DNA sequence. Mutations can be of many types, such as substitution, deletion, insertion, and trinucleotide repeat expansions. Mutations in repair genes may lead to serious consequences such as cancer.

what part of the cellular respiration pathway is affected by cyanide?
The ferric ions' cytochrome oxidase in the mitochondria makes a reversible chemical bond with cyanide. By preventing the conversion of oxygen to water, this essentially stops cellular respiration.
What is the role of cyanide in cellular respiration?Heme-containing proteins include Fe3+, which cyanide binds to. As a result, the electron transport chain's terminal cytochrome complex IV is inhibited.
Cyanide's blockade of complex IV depletes ATP, which leads to cell death.
Because the molecules are so small and can disperse quickly throughout the entire body, cyanide can kill so quickly by damaging all major organs and tissues in a short period of time.
Therefore, electron transport system is affected by cyanide in cellular respiration.

A large protein needs to enter a cell to help preform a function explain what process the cell must use to allow the protein to enter and why
Answer:
The protein is too large to simply diffuse across the phospholipid bilayer of the cell, so it uses phagocytosis to diffuse across, where it is contained in a vesicle and pinched into the cell? Credits to yahoo answer. Hope I could help sweets.
Cell membranes acts as a barrier for the large,charged and polar molecules due to their hydrophobic nature.
These molecules are transported with the help of membrane proteins such as carrier proteins across the plasma membrane by a process known as facilitated diffusion. These membrane proteins diffuse larger molecules across the cell membrane that cannot be transported by simple diffusion.

How does biotic carbon change to the abiotic form of carbon
Answer:
A balanced carbon cycle is essential. Carbon is a major component in carbohydrates, fats and proteins. The carbon cycle involves the exchange of carbon between living organisms (biotic) and their atmosphere (abiotic). In the carbon cycle, carbon is constantly removed from, and returned to, the environment.
Explanation:
What do adenine, ctyosine, guanine, thymine, and uracil have in common
Adenine and guanine have a fused-ring skeletal structure derived of purine, hence they are called purine bases. ... Similarly, the simple-ring structure of cytosine, uracil, and thymine is derived of pyrimidine, so those three bases are called the pyrimidine bases.
