Answer:
I think option B and C is correct answer
Answer:
Contains large polytene chromosome that permit visual inspection of genomic events.
Were used to study the genetic effects of mutations.
Were used to establish the concept of chromosomal inheritance.
Explanation:
<em>Drosophila melanogaster </em>is a model organism that is used by scientists to study the genes and effect of a mutation on the genes. Drosophila is used as a model organism as it has a very short life cycle and the offspring can be produced in a short duration of time.
Because of these characteristics, Thomas Hunt Morgan wanted to study the factors of inheritance on the <em>Drosophila</em> and concluded in the form of the chromosomal theory of inheritance by the effect of mutation on genes that lead to linkage mapping.
Also, the salivary gland of fruit fly contains the polytene chromosome which allows us to look into the gene events.
Thus, the selected options are correct.
Cellular respiration is the process by which the body breaks down sugar like glucose, to release ATP, which is an energy storing molecule. This is how the body gets energy from food.
Correct answer: B). Cells spend the most time in interphase, where they grow and their DNA replicates.
The cell spends its most of the time in the interphase, during this phase of growth, cell continues to grow and carry out its metabolic activities which are necessary for regular growth and maintenance.
During this phase of the cell cycle, a lot of protein is synthesized in order to double its size. The important changes that occur in this phase include DNA duplication and division of chloroplast and mitochondria.
Hence, the correct answer would be option B.
I believe the first answer is 140 w. The second is elastic potential energy.
