How are photosynthesis and cellular respiration related?

A. The products of photosynthesis are the reactants of cellular
respiration

B. Cellular respiration is the process animals use to produce glucose,
while photosynthesis is the process plants use to produce
glucose.

C. Photosynthesis produces water molecules, while cellular
respiration splits water molecules apart.

D. Cellular respiration provides the energy for photosynthesis.

Answers

Answer:

I would say your answer for this question would be Option D: Cellular respiration provides the energy for photosynthesis.

Explanation:

Photosynthesis is  the process by which plants use the energy from sunlight, carbon dioxide, and water and convert them into food, and Cellular resipration is the process by which organisms use oxygen to break down glucose and convert it to usable energy. That means that Option B can be crossed out, along with Option C. In Option A, the products of photosynthesis are not the reactants of cellular respiration, but rather the user of the energy that Cellular respiration provides. That means you can cross out Option A, and now you are left with Option D as your answer.

Answer:

A. The products of photosynthesis are the reactans of cellular respiration

In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers.

What is Microscope?

Microscope: a device that magnifies small objects, giving the user a close-up view of minuscule structures at a scale suitable for observation and analysis.

Even though optical microscopes are the focus of this article, an image can also be magnified by a variety of different wave types, such as acoustic, X-ray, or electron beams, and is then captured using direct or digital imaging, or a combination of these techniques.

The magnifying power of a microscope is a dimensionless ratio that expresses how often the thing under examination seems to be magnified.

Therefore, All organisms come from pre-existing cells that divide.

What is another term for the responding variable?
O primary variable
dependent variable
independent variable
uncontrolled variable

The answer is DEPENDENT VARIABLE
-edgy 2021

Answers

Answer:

B. Dependent variable.

Explanation:

An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).

Hence, an experiment is used by scientists or psychologists to illustrate how a change in variable affects behavior.

This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.

In an experiment, there are two (2) main types of variables and these are;

I. Independent variable: this is the variable that is being manipulated or alters and as such it is the cause of a behavior. This variable stands alone.

II. Dependent variable: this variable is the direct effect of the actions of the researcher in an experiment.

Basically, the dependent variable is the variable that is being measured and tested by an experimentalist.

Hence, dependent variable is another term for the responding variable because it responds to an action.
