Answer:
-all species change gradually over time.
Explanation:
Mutation often results from cell replication and division. These occur as small, random, errors within the genetic code that become more common or stable within a population over time as traits.
As organisms live within varying niches, environmental changes may render some genetic traits obsolete. However, others may become more beneficial as an adaptation. These adaptations, which make an organism and its offspring suited to a niche, and more likely to survive and reproduce become inherited- this process is called evolution.
The number of new cases of a particular disease contracted within a defined population in a specified period is referred to as the incidence of the disease.
Population is defined as a group of similar type of organisms. This group of organisms live in the same area, they require same resources, have similar types of habits. The most essential criteria is that they can breed and reproduce among themselves.
Incidence of a disease is the data that provides information about the number of people affected by a disease at a given period of time. The likelihood of a person getting affected by the disease can be estimated using incidence.

They have two identical alleles for a gene, so in a genetic cross, each parent contributes only one form of a gene, making inheritance patterns more detectable.
Answer:
Analysis of the data shows that the ratio of floating algae to sea floor algae dramatically increased at the same time that oysters were removed from the Bay. ... (It is also possible to infer from the graph that high floating algae levels led to the decline in oysters.
