Answer:
The correct answer is 25%.
Explanation:
Considering that Hemophilia B is an X-linked recessive disease, than for it to be observed in female offspring, the mother must be homozygous recessive because females have XX chromosomes and if the father transfers only the dominant gene then the female offspring will always be heterozygous dominant.
In the case of a father who carries the dominant gene on his X choromosome and a mother who is heterozygous for the disease meaning she has both the dominant and the recessive gene, if we calculate the percentages for this situation, we see that for the first generation, one female offspring is heterozygous dominant, one female offspring if homozygous, one male offspring carries the dominant gene on his X chromosome and the other male offspring carries the recessive gene on his X choromosome which is the one that carries the disease.
I hope this answer helps.
Answer:
The correct answer is homologous.
Explanation:
A structure that is derived from a common ancestor is called homologous structure. So homologous structure is the characteristic of divergent evolution that means divergent evolution give rise to homologous structures.
So as the marsupials are mammals that were diverged from placental mammals very early in mammalian evolution, the membranes of skin that allow Australian sugar gliders and North American flying squirrels to glide are homologous because divergent evolution gives rise to homologous structures.
The function of these homologous structures can be the same or can be different. Therefore the correct answer is their membrane are homologous.
Breaking the bonds in a polysaccharide would provide the body with the most energy. Thus, the correct option is D.
<h3>What is Polysaccharide?</h3>
A polysaccharide may be defined as a type of carbohydrate in which molecules are held together by glycosidic bonds. Examples include starch, glycogen, and cellulose.
Breaking such chemical bonds (glycosidic bonds) present in between polysaccharides molecules yield the release of glucose that provide excessive energy for the living organism for metabolism.
Therefore, the correct option for this question is D.
