Explanation:
Avg speed × total times = total distance
20×25=500
Since acceleration in the 1st interval is same as deceleration in the 3rd interval and deceleration is from the same velocity achieved after acceleration, t

Answer:
genetic drift
Explanation:
Genetic drift is a change in the frequency of an allele within a population over time. There are no environmental influences that cause genetic drift to occur.
Answer:
The ten percent law states that the total energy content of a trophic level in an ecosystem is only about one-tenth (or 10%) that of the preceding level. The trophic levels of any ecosystem can be arranged in a pyramid shape to show the amount of energy available to support one trophic level to the next.
Food, water, shelter, and warmth represent <u>physiological</u> needs in Maslow’s hierarchy of needs.
Abraham Maslow proposed and developed a theory in human development psychology titled "A theory of human motivation" in 1943.
Maslow's Hierarchy of Needs can be defined as a pyramid model which typically represents the fundamental (basic) needs of an individual, that are essential and required to be met before he or she can achieve complete growth, development and self-actualization.
The five (5) levels of Maslow's Hierarchy of Needs in a chronological order are;
According to Abraham Maslow the psychological needs comprises:
I. Food.
II. Water.
III. Shelter.
IV. Warmth.

Human cells that contain one set ofchromosomes are called gametes, or sex cells; these are eggs and sperm, and are designated 1n, or haploid.Matched pairs of chromosomes in a diploid organism are called homologous (“same knowledge”)chromosomes
