the answer is endonuclease enzyme
Answer:
D) a genetic bottleneck
Explanation:
Genetic bottleneck refers to the sudden reduction in the population size due to some adverse climatic factors such as natural calamities. It changes the allele frequencies since the survivor population mostly have different allele frequencies than the original population.
In the given example, an earthquake kills 98% of the squirrels. The survivor population exhibits different allele frequencies for the gene responsible for the thickness of stripes. Therefore, it represents a genetic bottleneck.
Answer:
A non-vascular plant is a plant without tubes to carry water and nutrients throughout the plant. Non-Vascular plants are less complex than vascular plants. ... Non-Vascular plants cannot grow very tall and because of their small sizes they can absorb enough water to carry materials throughout the plant.
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose
The definition of a biome is the community of many ecosystems in one general area. Many ecosystems can exist in a biome because a biome could have a water ecosystem and a dirt ecosystem.
