What type of evolutionary mechanism did this story show?

1 answer:

6 0

Allele frequencies in a population may change due to four fundamental forces of evolution: Natural Selection, Genetic Drift, Mutations and Gene Flow. Mutations are the ultimate source of new alleles in a gene pool. Two of the most relevant mechanisms of evolutionary change are: Natural Selection and Genetic Drift.

Answer:

The given situation is an example of the Positive feedback loop.

Explanation:

Positive feedback is the phenomenon in which the effects of the small disturbances on a particular system can result in an increase in the perturbation magnitude. Positive feedback increases the input and causes instability in the system. Therefore, it refers to positive loop gain about closed loop of the cause and effect.

Therefore, the given situation is an example of the Positive feedback loop.

When scientists are doing research to determine how the environment affects a life form, it often takes many years to reach a co

ki77a [65]

When using the term 'life form' I assume you are speaking of animals, bacteria, etc. Scientists take years to find their desired conclusion because of how the environment tends to change quite frequently (Depending on where the creature lives). The earth is constantly revolving and rotating, which causes changes in the environment. These changes affect the animals behavior, eating habits, and overall chances of survival. A factor that must also be considered is that scientists have to examine these creatures in their natural habitat which can be an issue depending on where they live. For example, if I were to study the behavioral patterns of a Leopard, it would be extremely difficult to do so because the Leopards are specifically keen at camouflaging in their environment. That would make observing its behavioral patterns very frustrating and time consuming. In a way, mother nature is always against us.

VikaD [51]

Answer:

Translation will be affected.

Explanation:

Ribosomes are the sites where the process of translation errors. Translation can be described as the process by which mRNA is converted into the amino acids which make up specific proteins of the body. If a mutation in the genes that code for proteins of the ribosome occurs, then the process of translation will be affected. Faulty proteins may be formed as a result of this mutation which can be harmful for the body.

Bacteria and eukarya are thought to have diverged from archaea. a. True b. False

miv72 [106K]

False. The root of the Eukarya is probably within the Archaea, but this was only discovered six months ago. The consensus hasnt yet shifted from thinking the tree of life has three distinct domains. In any case, bacteria are a separate domain to Archaea.
