Answer:
B
Explanation:
They altered rocks into soil that was able to support simple plants such as grasses. This is an example of altering the environment around them to make it more habitable for other species.
Answer:
The dispersion pattern of the population depends on the type of the population and their distribution in the environment. Different types of dispersion are uniform, random and clumped.
The uniform dispersion occur when the population is evenly spaced out in the area. Random dispersion is independent of the other individuals and randomly spaced. Clumped dispersion is greatly influenced by the behavior and the resources. Population are present in small patches.
Answer:
Adhesion and surface tension
Explanation:
Capillary action is the tendency of a liquid to rise or fall in a narrow tube. Two main terms are required to explain capillary action; adhesion and cohesion.
Cohesion is the force of attraction between molecules of the same kind while adhesion is the force of attraction between molecules of different kinds.
Forces of adhesion causes water to move up in a capillary tube. The water is held as it rises by surface tension forces acting on the circumference of the meniscus. The water keeps rising in the tube until the weight of the water drawn up in the tube balances the surface tension acting at the top column of the water.
Answer:
<h2>1. toward</h2><h2>2. DNA ligase</h2>
Explanation:
- DNA replication is a process in which the synthesis of the new strand takes place from parental DNA or strand.
- DNA polymerase is an important enzyme that is responsible for the adding of the nucleotide and thus forms a new strand.
- During the process of synthesis one strand is synthesized in continuous forms that goes toward the replication fork and called as a leading strand that moves in 3' to 5' direction.
- The other strand that is synthesized in pieces form that is known as lagging strand and the pieces of the DNA is joined by an important enzyme known as DNA ligase.
