In the given question if the researcher has to study about the flu virus, the possible questions he would ask will be:
1. The life cycle of the flu virus.
2. Effect of the virus on the life of an organism.
3. The mechanism used by the virus to replicate and to infect any organism.
4. Molecular mechanism of a virus.
Genotypes of the dog color are:
BB dominant homozygous-brown phenotype
bb recessive homozygous-white phenotype
Bb heterozygous-tan phenotype
Cross between brown and pan dog would be:
P: BB x Bb
F1: BB Bb BB Bb
The ratio would be 1:1 (brown dog:pan dog).
Answer:
Option A
Explanation:
Sperm undergo more mitotic cellular divisions than egg and therefore have a higher risk of developing a spontaneous mutation.
As noted from the explanation given above...in the process of development in males, the sperm cells always undergo many mitotic cellular division throughout their life increasimg the males' chances of undergoing spontaneous mutations as compared to the females during development where it gets to a certain point in their lives where they stop producing egg cells after the once division.
Thus, the continuous divisions undergone by the sperm cells acquire more spontaneous mutations on the cell that produces this lycantrophy trait.
Answer:
No because the tectonic plate theory says that they move but if they didn’t move then it proves it wrong.
