Answer:
B. preservation of advantageous genetic mutations
Explanation:
The process of natural selection involves the preservation of advantageous genetic mutation in a given population.
Natural selection is one of the key factors that ensures the evolution of organisms.
- Desired traits that are able to survive adverse conditions like disease, food shortage, natural disasters are favored by the process of natural selection.
- Traits that also undergo advantageous genetic mutation in order to get a competitive advantage is also accrued to natural selection.
The answer is false (sorry I'm late.)
G1 is the cell growth phase where the cell accumulates nutrients and decide if it is going to undergo the cell cycle, as determined by the restriction point in G1. If the cell has insufficient nutrients or has not grown sufficiently to enter the cell cycle, it will remain in G1 or exit to G0 phase where it will not divide.
G2 occurs after S phase DNA replication in the cell cycle. In G2, the cell is growing and preparing for cell cycle by producing proteins required such as the centrosome.
Please do verify my answers with online sources. Thanks!
The lack of access to the healthy food has caused the growth of Sebastian to slow down. In the case healthy food is provided to him, he can grow into the size he was genetically suited to. This process is known as the canalization. Canalization term is used as the measure of the ability of any given genotype to result in the same phenotype in-spite of the environmental variability.
