Answer:
A mutation is generally referred to as certain alternations in the gene whether it may be DNA sequences, which may be beneficial, harmful or of no significance to the mutant gene bearing organisms.
Explanation:
- A mutation that increases the ability to store moisture in a dry environment is obviously beneficial. Because it prevents dehydration and maintains normal functioning in spite of adverse conditions.
- A color mutation that decreases a bird's chances of sexual selection is beneficial in the sense that it prevent certain abnormalities in offspring like sexual dimorphism. Also sexual selection often proves to be a threat to the survival of the organisms as per handicap principle.
- A mutation in non coding region of DNA is harmful, as it is often observed to facilitate expression of wrong proteins at inappropriate places.
- A mutation in the that does not changes protein synthesis increased white pigmentation on a prey animal in snowy environment as it had prevented adaption of the prey and hence harmful for survival of it.
- A mutation decreasing plant's height in competition to light, makes them less exposed to sun energy important for photosynthesis and hence it is harmful for the plant.
This statement is true, because the warmer the temperature, the faster the atoms move in a liquid
Answer:
B
Explanation:
Water moves from higher potential to lower potential i.e it moves from surounding to the cell.
Answer:
36 chromosomes in each cell
Explanation:
Mitosis is an equational division which means that it does not reduce or change the number of chromosomes in the daughter cells. Mitosis in a single parent cell produces two daughter cells each having the same DNA content and the number of chromosomes is present in the parent cell. Each chromosome after the S phase has two sister chromatids that separate from each other and are segregated to the opposite poles of the cell during anaphase of mitosis. Therefore, a cell with 36 chromosomes will form two daughter cells after one round of mitosis. Each daughter cell would have 36 chromosomes.
