The following experiment is used for the following question vered a species of moth that lays its eggs on oak trees. Eggs are laid at two distinct times of the year: lowering and in midsummer when flowering is past. Caterpillars from eggs that A researcher discove early in spring when the oak trees are f flowers and look like oak flowers, but caterpillars that hatch in summer feed on oak leaves and look like oak twi? To answer this He put at least one How does the same population of moths produce such different-looking caterpillars on the same trees question, the biologist caught many female moths from the same population and collected their eggs. egg from each female into eight identical cups. The eggs hatched, and at least two larvae from each female were maintained in one of the four temperature and light conditions listed below. Temperature Day Length Springlike Springlike Springlike Summerlike Summerlike Springlike Summerlike Summerlike In each of the four environments, one of the caterpillars was fed oak flowers, the other oak leaves. Thus, there were a total ofeight treatment groups (4 environments × 2 diets) hich one of the following is not a plausible hypothesis that can be tested in this experiment A) Th e longer day lengths of summer trigger the development of twig-like caterpillars B) The cooler temperatures of spring trigger the development of flowerlike caterpillars. C) Differences in air pressure, due to differences in elevation, trigger the development of different types of caterpillars D) Differences in diet trigger the development of different types of caterpillars

Differences in air pressure, due to differences in elevation, trigger the development of different types of caterpillars.

Explanation:

A hypothesis can be described as a tentative statement which can either be supported by evidence from experiments or it can be discarded if the results of an experiment do not support a hypothesis.

In the scenario, mentioned in the question, the air pressure had nothing to do with the different type of caterpillars being formed neither was it the focus of the experiment.  Hence, the above mentioned hypothesis will not be supported by the experiments.

an individual’s sex (i.e., whether they are a male or female) is determined by the sex chromosomes. most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. typically, females have two x chromosomes (xx) and males have one x chromosome and one y chromosome (xy). conditions caused by changes (“mutations”) in genes located on the x chromosome are considered x-linked.

x-linked recessive inheritance

most x-linked conditions are recessive. this means that in a person with two x chromosomes (most females), both copies of a gene (i.e., one on each x chromosome) must have a change or mutation whereas in a person with one x chromosome (most males), only one copy of a gene must have a mutation. a female with a mutation in one copy of a gene on the x chromosome is said to be a “carrier” for an x-linked condition. a male with a mutation in a gene on the x chromosome is typically affected with the condition. because females have two copies of the x chromosome and males have only one x chromosome, x-linked recessive diseases are more common among males than females. however, x-linked recessive diseases can occur in both males and females.

for x-linked recessive disorders, an unaffected carrier mother who has a mutation in a gene on the x chromosome can transmit either the x chromosome with this mutation or a “normal” x chromosome to her children. if the father is unaffected, none of her daughters will be affected and all of her daughters will be unaffected—since they will inherit at least one normal x chromosome from their father. however, each daughter will have a 50% chance of being an unaffected carrier like her mother and a 50% chance of both x chromosomes being normal.
