Answer:
A
Explanation:
Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working.
Increased afterload physiologic change increases cardiac work but does not enhance cardiac output.
<h3>What about cardiovascular system?</h3>
- Heart and blood vessels, which make up your cardiovascular system, deliver oxygen and nutrition to your body's organs so they can function.
- Blood vessels also transport waste such as carbon dioxide to be disposed.
- Conditions affecting the heart or blood vessels are collectively referred to as cardiovascular disease.
- It is frequently associated with atherosclerosis, an accumulation of fatty deposits in the arteries that increases the risk of blood clots.
- The heart, blood arteries, and blood make up the cardiovascular system.
- Its main job is to carry deoxygenated blood back to the lungs and to carry nutrients and oxygen-rich blood to all regions of the body.
- The most typical cause of coronary artery disease is atherosclerosis, which is a buildup of fatty plaques in your arteries.
- Atherosclerosis can be brought on by unhealthy lifestyle choices such smoking, being overweight, not exercising, and eating poorly.

Answer:
Convergent evolution
Explanation:
Convergent evolution is a type of evolution of similar features and/or structures between organisms that are not phylogenetically related. This type of evolution is known to create analogous structures/organs that exhibit similar or the same functions but were not present in the last common ancestor of these taxa. An example of analogous structures (and therefore also of convergent evolution) are the wings of bats and of insects (e.g., butterflies). Conversely, divergent evolution is a type of evolution where species phylogenetically related, i.e., species that share a common ancestor, evolve and accumulate differences over time.
