Answer:
Some factors that may cause a decrease in population size:
- a high mortality rate due to an infectious disease
- a low birth rate
- a high mortality rate due to interspecific competence
- a high emigration rate
Explanation:
In biology, population size (N) refers to the total number of individuals in a given population. The four main factors that affect population size are birthrate (natality), death rate, immigration rate (i.e., the number of individuals of a given species that move into a population), and emigration rate (i.e., the number of individuals of a given species that move out of a population). Both birthrate and immigration are known to increase N, while death rate and emigration are rates known to decrease this value.

The name sounds male so that should be right.
The correct answer is cohesion and adhesion.
The cohesion of the water means that the H₂0 molecules are attracted by other H₂O molecules (molecules of the same kind are attracted). Adhesion is the attraction of molecules of different kinds. <span>Water moving up a straw is an example of the motion of water against gravity which depends on the attraction between water molecules and the walls of the straw (adhesion), and also on the attraction between water molecules (cohesion).</span>
