<u>Answer:</u> The correct answer is it is a single replacement reaction, and the anions in the two ionic compounds are different.
<u>Explanation:</u>
Single displacement reaction is defined as the reaction in which a more reactive element replaces a less reactive element from its chemical reaction. The chemical equation showing single displacement reaction follows:
A is more reactive element than element C.
Non-metals are the elements which gain electrons to attain negative charge known as anions.
For the chemical reaction:
As, non-metals are present on both the sides of the reaction, thus this means that anion in the chemical reaction are different.
<u>For Example:</u> The reaction of sodium bromide with chlorine gas, the equation follows:
Hence, the correct answer is it is a single replacement reaction, and the anions in the two ionic compounds are different.
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.
Answer:
Astrocytes
Explanation:
Astrocytes are the most abundant cells in the central nervous system that twine around nerve cells supporting the brain and spinal cord. They perform many functions; such as providing the nuerons with nutrients, control the blood brain barrrier and blood flow. Astrocytes are basically responsible for maintaining the central nervous system homeostasis.
