Some of the constants in the experiments are;
F) Pencil sharpeners: Both groups used the same tool to sharpen pencils.
G) The workers: Both groups had the same number of workers (25 each).
E) All worked for one hour: Both groups had the same amount of time to complete the task.
What are constants in experiements?In experiments, constants are those variables that are kept the same or held constant throughout the experiment.
The constant variables help to know whether any observed changes or effects can be attributed to the variable being tested, rather than other factors.
By controlling these the constant variables, scientists can then reduce the things that could be a source of error in their research and increase the accuracy and reliability of their results.

Let’s review the normal baroreceptor reflex. Drag the labels onto the figure to create a flow chart of how the baroreceptor reflex would respond to decreased mean arterial pressure. View Available Hint(s)
Mechanoreceptors known as baroreceptors enable the autonomic nervous system to communicate information generated from blood pressure.
Thus, Baroreceptors come in two varieties: low-pressure volume receptors and high-pressure arterial baroreceptors, both of which are triggered by stretching of the vessel wall.
Carotid sinuses and the aortic arch both include arterial baroreceptors. The atria, ventricles, and pulmonary vasculature all include low-pressure volume receptors (also known as cardiopulmonary receptors).
When you experience something that raises or lowers your blood pressure, the baroreceptor reflex keeps it constant. Your blood pressure is swiftly returned to normal range after a complicated sequence of procedures.
Thus, Mechanoreceptors known as baroreceptors enable the autonomic nervous system to communicate information generated from blood pressure.

Where did the carbon in all living things come from?
A} It was made in stars that lived before the solar system formed.
B} It was made in the formation of the solar system.
C} It was made during the big bang.
D} It was produced by cyanobacteria.
The carbon that is present in all living organisms comes originally from the collision that took place millions of years ago. So the correct option is option C.
Carbon is present in all living organisms. It continuously flows through the atmosphere so that there is a balance in the cycling of the nutrient and all organisms can take up the carbon from their environment.
Plants take up atmospheric carbon to synthesize their food. Animals also take it in the form of carbohydrates and proteins and they give off the carbon as carbon dioxide into the atmosphere. When these plants and animals die they are eaten up by decomposers, releasing the carbon-bound in different forms to be released back.
So the correct answer is option C.

Decomposition is a crucial step in the cycling of carbon, nitrogen, and phosphorus.
Decomposition is the breakdown of organic matter into more easily digested inorganic substances such carbon dioxide, water, nitrogen, and phosphorus by bacteria and fungi. The plants can then absorb these inorganic substances and employ photosynthesis to create new organic stuff.
Because it releases nutrients that were bound up in organic matter back into the soil, so they can be absorbed by live plants and recycled through the food chain, decomposition is an essential process in natural ecosystems.
