Answer:
Evolution occurs when these heritable differences become more common or rare in a population, either non-randomly through natural selection or randomly through genetic drift. This occurs because organisms with advantageous traits pass on more copies of these heritable traits to the next generation

Which ACTN3 genotype (RR, RX, or XX) would provide these Olympic marathon athletes with an advantage, and why?
Answer:
XX
Explanation:
ACTN3 genotype i.e. XX provides advantage to the Olympic marathon athletes because it strengthens the fiber of the muscles. This gene is also called the gene of speed. This ACTN3 gene has a great influence on the type of fiber that makes body muscles, and they are also linked to strength and endurance so we can conclude that this gene provides benefits to the Olympic marathon athletes by giving strength to the fiber of muscles.
ACTN3 genotype is the gene encoding for the actinin of the skeletal muscle fibres. XX of the ACTN3 genotype will be advantageous for marathon athletes.
What is ACTN3 genotype and XX?ACTN3 genotype is the gene encoding for the protein of the skeletal muscles fibres that are associated with muscular performance. This protein is expressed in the myofibers with a high twitching ability and result in a high-velocity force.
The XX genotype provides strength to the muscles and is the gene coding for the proteins that give speed. They are also responsible for endurance and are beneficial for athletes.
Therefore, XX of the ACTN3 genotype is advantageous for athletes.

How do animals help recycle carbon atoms?
Answer:
animals, oxygen combines with food in the cells to produce energy for daily activity and then gives off carbon. The carbon combines with oxygen to form carbon dioxide (CO2) and is released back into the atmosphere as a waste product when animals breathe and exhale

What is reflex arc?A reflex arc is a neural pathway that mediates a reflex action. It is a rapid and automatic response to a specific stimulus that does not require conscious thought or decision-making from the brain. When a sensory receptor in the body, such as the skin or muscles, is stimulated, a nerve impulse is transmitted to the spinal cord, where it is processed by an interneuron.
The interneuron then sends a signal through a motor neuron to the effector, such as a muscle, causing a rapid and involuntary response, such as pulling your hand away from a hot stove. This entire process occurs without conscious control from the brain, allowing for quick and protective responses to potentially harmful stimuli.
