The answer is B .Dental Hygienist
Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death.
Answer:
D. A and B
Explanation:
Some <em>Apis mellifera </em>bees genetically inherit the hygienic behaviour to remove the dead and diseased larvae from beehives by uncapping the sealed cells. This activity maintains the overall health of the bee colony by protecting it from unwanted pests and pathogenic diseases. Usually both hygienic and non hygienic bees survive well.
Here, in hot summer many bees had perished due to disease and hot climate. Accumulation of dead larvae in hives of non hygienic bees would have invited more pathogens and created infectious conditions in summer. Hence their hives could not survive. Now the remaining hygienic bees will mate with each other and the offspring will have more chances to be born with the hygienic trait. Hence the frequency of alleles determining this trait will increase in this population. This would also be an example of natural selection as hygienic bees were preferred by the nature over non hygienic ones to survive in hot season.
Answer:
The answer to this question is B.
Explanation:
Summary. Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
Answer:
Complete dominance
Explanation:
Gregor Mendel (1822 - 1884) was regarded as the "FATHER OF GENETICS" due to his immense contribution to discovering the principles that govern inheritance in organisms. In one of his several experiments, he performed a cross between true-breeding tall plants (TT) and true-breeding short plants (tt).
From this cross, Mendel found out that the F1 generation were all tall. He self-crossed the F1 generation and obtained F2 offsprings in a ratio 3 tall: 1 short. This shows that the tall phenotype allele (T) is dominant over the short phenotype/allele (t), which was being masked in the F1 generation i.e. Tt. This inheritance pattern is called COMPLETE DOMINANCE.
