Answer:
Asexual reproduction is when the parent reproduces without having any sexual contact with a partner and they don't need any kind of fertilization from another partner, sexual reproduction requires both a male and female partner, and fertilization of eggs must occur.
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:
Stephen Stearns states that natural selection doesn't mean the survival of the fittest organisms, but rather this mechanism is illustrated by the selective reproduction of the fittest. Natural selection can be classified into distinct types, including directional, disruptive and stabilizing selection, which are in turn based on sexual selection. These types of selection are driven by different outcomes that have different dynamics.
Complete question:
Phenotype Genotype Number of Individuals
Long-tailed TT 260
Long-tailed Tt 160
Short-tailed tt 80
If 20% of the long-tailed cats got their tails stuck in something and failed to reproduce, what would be the expected change in frequency of T in the next generation
Answer:
The expected change in allelic T frequencies probably changes from 0.6 to 0.57 in the following generation.

Answer:
In insects such as cockroach, grasshopper
Explanation:
Insects such as grasshopper has open circulatory, in them the body fluid is the hemolymph. The hemolymph does contain any respiratory pigment. It bathes the organs directly as it is pumped between open spaces in the body.
Thus, in insects, the blood and the interstitial fluid considered to be the same body fluid?
