An allele is a variant form of a gene. some genes have a variety of different forms,which are located at the same position, or genetic locus, on a chromosome.
Answer: The correct answer for the first question is- B) Mechanical.
Adaptation can be described as a process of change in an organism over time that facilitates its survival in the changing environmental conditions. It results due to mutation or genetic change in the individual that gives a benefit to the organism. It exhibits change in structure ( like succulent plants in desert), function, or behavior.
Mechanical is not a type of adaptation as it deals with movement of objects.
The correct answer for second question is- C) Variations.
Variation among organisms in a population results from change in the genetic material or their genetic sequences. Change at the genetic level is thus reflected in the phenotypes ( like different color of feathers in birds).
Thus, difference is in the feather color reflects variations.
The correct choice is velocity=distance/time of v=d/t
Answer:
bb would be the phenotype white fur
Explanation:
B is dominant over b. It takes two recessive alleles to produce the phenotype of white fur.
