Answer:
GLD-1 is a regulatory protein whose function is to regulate the expression of MES-3.
Explanation:
Since the MES-3 protein itself is not modified but only its quantity is, then it is likely that the GLD-1 protein is only inhibiting MES-3's expression; keeping it at a certain level set by the organisms DNA.
Hypothesis: large servings might encourage children of today to eat more data and sugars than children ate a generation ago
<h2>C) option is correct </h2>
Explanation:
Natural selection as proposed by Darwin is a selection pressure which operates in a population and allow the best fitted genotype to survive in changing environmental conditions and eliminate the other genotype which are not fit
Causes of natural selection include: Genetic drift, mutation(changes allelic frequency) and sexual selection
In the given example, condition necessary for natural selection to occur on the mouse population is traits that affect the survival of the mice vary among individual mice, in this condition superior genotype will get the opportunity to reproduce and inferior genotype does not get opportunity to reproduce thus their genotype in population does not increase rapidly and hence they become eliminated leading to genetic drift

Explanation:
Dependent on the level of comparison four types of homology are defined: ( 1) Iterative ( = serial = homonomy), (2) ontogenetic, (3) di- or polymor- phic, and (4) supraspecific homology. ... Scientists have recently been paying renewed attention to the homology question.
Homology is the study of likeness, the similarity between species that results from inheritance of traits from a common ancestor. The study of similarities is broken up into three main categories: structural, developmental, and molecular homology.
