Answer:

a. A hypothesis that does not generate a testable prediction is not useful.

Explanation:

In the scientific method, we generate a hypothesis to explain a phenomenon. After this, it is necessary to create a method to test the hypothesis and make predictions. Moving forward, we test this methodology, generating results and reject or not reject the hypothesis. If the hypothesis can't be tested, the scientific method can't be applied.

Alpa wants to change 0.54 kilometers into a smaller metric unit
wlad13 [49]

If Alpa wants to change 0.54 kilometers into a smaller metric unit, she will be required to multiply.

<h3>What is a Metric unit?</h3>

A Metric unit may be defined as a technique of measurement in which the basic units are the meter, the second, and the kilogram. These units are interchanged with one another by using several formulas of conversion.

The complete question is as follows:

Alpha wants to change 0.54 kilometers into a smaller metric unit. She will have to:

  • multiply
  • divide
  • add
  • subtract

Therefore, If Alpa wants to change 0.54 kilometers into a smaller metric unit, she will be required to multiply.

For example, In case, if she wants to convert 0.54 into meters, then she has to multiply it by 1000, that is, 0.54 * 1000 = 540 meters.

the diagram below represents levels of glucose and insulin found within the bloodstream of a healthy person
Makovka662 [10]
The increase in insulin level following an increase in glucose level in the blood can best be explained by A FEED BACK MECHANISM THAT REGULATE THE BLOOD GLUCOSE LEVEL.
Insulin is an hormone that is secreted by the pancreas and it functions by regulating the amount of glucose that is found in the blood. When the level of glucose in the blood is higher than normal, insulin interfere by converting the excess glucose into glycogen. The glycogen is stored in the liver and in the skeletal muscles and they will only be converted back into glucose, if the level of glucose in the blood is lower than normal.

Which organelle is found in both eukaryotic cells and prokaryotic cells:
Ludmilka [50]

Answer:

c. Ribosomes

Explanation:

Ribosomes can be found in eukaryotic and prokaryotic cells.  In eukaryotes they are distributed by the cytoplasm, or trapped in the membranes of the endoplasmic reticulum. In prokaryotes they are found free in the cytoplasm.  In both cells, ribosomes intertwine into an RNA molecule and form polysomes.

Ribosomes are made up of two subunits, the two parts are made up of RNA molecules and proteins. This molecule has the main function of protein synthesis, that is, it is through it that aminoacids reconcile to produce proteins.
