Answer:
The isopods will be found under the leaf litter.
Explanation:
Isopods are crustaceans and they live in freshwater, marine water or on land. The forms of isopods that are found on land mostly prefer the cool and moist environment.
As the biologist will leave them on leaf litter, they will crawl to the area under the leaf because the area under the leaf litter is relatively cool and moist and there they can get an environment which is suitable for their living. Thus when the biologist will come after one hour, most of the isopods will be found under the leaf litter.
Answer:
The chromosome number of the somatic cells.
Explanation:
The body mainly consist of two types of cell known as somatic cells and germ cells. The somatic cells divide by the process of mitosis whereas germ cells generally divide by the process of meiosis.
The skin cells of the giant panda has 42 chromosomes. The skin cells are included in the category of somatic cells. The skin cells are diploid in nature and divides by the process of mitosis only. These cells remains diploid after the mitosis process.
Thus, the chromosome number of the somatic cells.
Answer: C. Substitution
Explanation:
Substitution is a type of mutation in which a base or amino acid is replaced by another. For example in sickle cell disease, the mutated sickle haemoglobin results from a point mutation of a single amino acid substitution in which a valine residue replaces a glutamate residue at the sixth position in the two beta chains.
