Answer:
Live a healthy lifestyle and avoid anything that may trigger such Diseases.
Answer:
Punctuated equilibrium
Explanation:
The idea of "punctuated equilibrium" suggests that species will show little to no evolutionary change throughout their history. When evolution does occur, according to this idea, it happens sporadically and relatively quickly compared to the species' full duration on Earth.
The layer of the sun that is labeled (B) in the figure is called the corona.
Answer:
The biologist is analyzing deleterious and beneficial mutations.
Explanation:
In general, mutations are deleterious genetic changes that negatively affect the fitness of the individual in a particular environment. However, there are occasions where a mutation may be beneficial. These mutations are beneficial because they confer an adaptive advantage (for example, by generating new versions of proteins) that enable the individual to adapt to their environment, thereby increasing their chances to survive and reproduce. If a beneficial mutation is new it will be distributed disproportionately among populations, thereby it is possible to determine the novelty by determining the frequency of the mutation among populations. Ideally, this new mutation should have a value of 0 in the non-target populations (i.e., this mutation does not exist in these populations), and a very low value in the target population (i.e., this mutation appeared very recently). Since mutations provide the raw material for natural selection, it is expected that a new mutation increases their frequency in the population, but if this genetic change is deleterious in a particular environment, natural selection will decrease their frequency. Deleterious mutations are accumulated in populations with small sizes faster than it can eliminate them, thereby the identification of these genetic changes can result useful for the design of conservation strategies in endangered species.
