Answer:
The correct answer is b. actors have to be more likely to carry the altruistic allele than non actors.
Explanation:
Altruism is the behavior by an organism that benefits other organisms by costing its own fitness. The actor is the individual who is doing altruism and the recipient is the individual who is getting benefited by the actor's altruism.
An example of altruistic behavior can be seen in animal kingdom easily. Vampire bats give blood to those members of the community who were not able to go for search for blood show altruistic behavior.
Actors have altruistic genes that suggest them to behave altruistically. Non-actors may not contain alleles of altruism but the recipient might have altruistic alleles.
Hamilton's rule says that natural selection will favor the altruistic allele when rb > c.
where r = coefficient of relatedness between donor and recipient
b = benefit received by recipient and
c = cost paid by altruist.
Therefore, the correct answer is b.
The nucleus controls what happens within the cell
Answer:
Photosynthesis doesn't occur at night. When there is no photosynthesis, there is a net release of carbon dioxide and a net uptake of oxygen. ... the rate of photosynthesis is higher than the rate of respiration. there is a net release of oxygen and a net uptake of carbon dioxide.
The two serous membranes of pericardium are :visceral pericardium,parietal pericardium.
Answer:
Enzymes are the bio-catalyst produced by the body.
They increases the rate of bio-chemicals reaction taking inside the body.
They form enzyme-substrate complex in order to increase the rate of the reaction.
They are highly specific in nature.
Example:
- Hexokinase catalyses the conversion of glucose to glucose-6-phosphate.
- Salivary amylase catalyses the breakdown of starch into maltose (simpler sachharides).
- Protein kinase is an enzyme used to activate or deactivate other by adding phosphate group to them.
