Answer: a) a different paternal and maternal allele at a particular locus
Explanation: Hetero-zygote are referred as the organisms that represent the two different alleles of a particular gene. It can have different individual paternal and maternal allele from a gene.They have the nature of establishing alleles that among the two alleles, one of them has a dominant approach. Therefore the correct option for the given statement in the question is option(a) .
If the ulnar nerve is damaged, it could result to the following:
-
a condition known as “claw hand”
- the inability to adduct or abduct the fingers "ape hand"
- a diminished ability to oppose the thumb toward the little finger
In simple terms, damage to the ulnar nerve results in the inability to flex the wrist.
The correct answer is option C, that is, the insects could grow resistant to the pesticide in the genetically-modified corn and become immune to regular pesticides.
The genetically modified organisms are usually developed to be more resistant to pesticides or produce pesticides themselves. The GM crops do not have monarch butterflies or honeybees. However, the insects that consume genetically modified crops can, in some of the circumstances, begins to establish a resistance to the protein that usually kills them.
Answer:
sorry i didn't understand your question
Explanation:
Answer:
d. Humans and other animal hosts lack peptidoglycan cell walls.
Explanation:
Humans and other animals lack cell walls. Bacterial cells have peptidoglycan cell walls around them. The absence of cell walls in the cells of human and other animal host ensures that these cells are not affected by the drugs that target the peptidoglycan cell walls to kill or slow down the growth of the bacterial pathogen.
This makes the drugs specifically target the bacterial cells only while not affecting the host cells. If a drug would target a component present in cells of both the pathogens and hosts, the host cells would be most likely to be harmed by the drugs.
