Answer:

The correct answer is D. Immigration is when animals move into an ecosystem.

Explanation:

Animal migration is the movement of animals from one habitat to another, caused by specific needs for food, hibernation, climatic issues, or even to escape predators. Migration, like the migration of birds, is a directed migration, that is, it aims at a specific end; while dispersion is the more or less random distribution of a group of individuals over the habitat. Thus, within the migratory process of animals, two movements are distinguished: emigration, which is the departure of animals from a place, and immigration, which is the entry or arrival of these to the new habitat.

Nezavi [6.7K]

Answer:

Independent Variable - Soil, Dependent Variable - Height, Control Variable - Sun and Water

Explanation:

First we should define what the variables in the experiment are.

Independent variable is the aspect of the experiment that has a different value for each subject in order to find out how it affects the dependent variables.

Dependent variable is the variable that is kept under observation and recorded by the experimenters in order to track the changes and define its relationship with the other variables/parameters.

Control variable is the variable that is kept constant intentionally by the experimenters to be able to define the relationship between the other variables more clearly and easily.

In the example given in the question, there are one of each variable mentioned above which are, according to the definitions;

Independent Variable - The Soil
Dependent Variable - The Height Of The Plant
Control Variable - The Amount of Water and Sun Exposure

What is the difference between mechanical digestion and chemical digestion?

Bad White [126]

Answer:

So, Mechanical and Chemical Digestion is the way of breaking down foods in the body. The difference between Mechanical and Chemical Digestion is, Mechanical Digestion involves the body's movement to make the food smaller and Chemical Digestion involves enzymes to break the food down.

Explanation:

Since Mechanical Digestion involves moving around to break the food down, you would get up and walk around a little to burn it to make it work and Chemical Digestion is just using the natural enzymes in the body to break food down.
