Answer:
True.
Explanation:
It is defined as, individuals that have certain inherited traits tend to survive and reproduce at higher rates because of these traits
Natural selection is defined as organisms developing inherited traits that better help them survive in their environment.

Law of demand
The regulation of demand for states that because the rate of a great decrease, the amount demanded of that correct increases.
<h3>What are the five Determinants of Demand?</h3>
The five determinants of demand are:
- The rate of the goods or service.
- The earnings of consumers.
- The expenses of associated items or services—both complementary and acquired together with a selected item, or substitutes sold rather than a product.
- The tastes or alternatives of customers will pressure demand.
- Consumer expectancies about whether or not charges for the product will upward push or fall withinside the future.
For combination demand , the wide variety of customers withinside the marketplace is the 6th determinant.

A, B and C are the events that will cause an ecological disturbance.
Rationale:
A. Introduction of a new species: When a new specie is introduced, it increases the competition in ecosystem with the native species for food, water, space and shelter. This affects the reproductive success of the native species and thus the dynamics of ecosystem.
B. Climate change: Climate change is different from a simple change of weather. The best example would be of Antarctica where the ice is melting fast due to the global warming. The native species find it harder to adapt to the warm temperatures.
C. Late spring snowstorm: Spring is the season where the plants grow and animals shed their fur. When snowstorms occur in this season they harm these plants and animals that live there.
Answer;
C) the amount of time that the two species have been evolving apart
Explanation;
-Scientists can use relaxed-clock methods to deal with variation in the rate of the molecular clock. By measuring the patterns of evolutionary rate variation among organisms, they can also gain valuable insight into the biological processes that determine how quickly the molecular clock ticks.
- The molecular clock hypothesis states that DNA and protein sequences evolve at a rate that is relatively constant over time and among different organisms. A direct consequence of this constancy is that the genetic difference between any two species is proportional to the time since these species last shared a common ancestor.
