Answer;
-Correlational; experimental
Two main types of designs used specifically in human lifespan studies are correlational and experimental.
Explanation;
-Psychological studies vary in design. In correlational studies a researcher looks for associations among naturally occurring variables, whereas in experimental studies the researcher introduces a change and then monitors its effects.
-An experiment isolates and manipulates the independent variable to observe its effect on the dependent variable, and controls the environment in order that extraneous variables may be eliminated. Experiments establish cause and effect. A correlation identifies variables and looks for a relationship between them.
This is incomplete dominance, you could use R for red W for white and RW for pink
well they havent found the right guy for them so they aren't doing the nasty
Answer:
Water molecules infiltrate in the soil through small pores made by soil fauna. If soil has high porosity, the water infiltrate quickly into the soil or if the soil has low porosity, so the movement of water is difficult in the soil.
Explanation:
Porosity refers to the comparison of total volume of rock in total volume of soil. If there more empty space in the soil we can say that the soil has high porosity.
