Answer:
heterozygote advantage
Explanation:
Usually if the mutation is present and the individual is only a carrier then they are heterozygous
Answer: A. Phenotype
Explanation:
Phenotype: the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
Genotypes produce phenotypes.
Answer: Sudden loss of habitat
Explanation:
Endangered species are animal or plant species that are in danger of going extinct.
This usually results from them suddenly losing their habitat and thus being exposed to unfamiliar conditions or threats that could end their existence. For instance, elephants losing their forest habitats in India and thus encroaching on farmland only to get shot for damaging farms.
Answer:
Decrease in genetic diversity reduces the chance of variation in the offspring.
Explanation:
If there is no variation, there will be no evolution. So, if there is a change in the environment (like an outbreak of a disease) that affects one of the organisms, it is likely to affect all of them and destroy the whole population. This would lead to extinction.
The position of the Earth in the solar system and more regional effects, such as carbon dioxide levels, all play a role in the causes of ice ages. Thus, option A is correct.
<h3>
What are factor that involve in ice age on earth?</h3>
When the orbital cycle turns back, these feedbacks—involving the spread of ice and the emission of greenhouse gases—work in reverse to warm the Earth once more.
A prolonged period of cooling of the Earth's surface and atmosphere is known as an ice age, which is marked by the development or presence of polar and continental ice sheets as well as alpine glaciers.
Flooding has increased along the U.S. coastline as a result of the warming, rising, and acidifying of the seas.
Therefore, The Earth is currently facing an ice age.
