Well , the student has not done justice to the question technically. He/she classified examples of cells entirely on other basis other than the observations seen on the prepared microscopic slides
<h3>Prepared microscopic slide</h3>
Prepared microscopic slides are set of slides that have been previously mounted by an individual who is a professional in the field.
It process involve immersing the sample ( either before or after fixation or mounting) in a dye solution and then rinsing and observing the sample under a microscope.

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.
Answer:
2, 4
Explanation:
Carbohydrates only contain the elements CHO (carbon, hydrogen, oxygen), so those are the only ones that could be used in the other types of molecules. Also, those molecules also contain the CHO molecules, so we can confirm that carbon and hydrogen will be used by the body for the production of proteins and lipids.
