The correct order of steps in an experiment would be:
- Identify the variables.
- Write out your hypothesis in an if/then format.
- Gather your materials.
- Analyze the data.
- Write your conclusion.
<h3>What is an experiment?
</h3>
An experiment is a term to refer to the process by which a hypothesis is supported/disproved. The experiments serve to explain the cause-and-effect relationship according to the results obtained.
Experimentation has some important steps that we must follow to demonstrate our ideas regarding a scientific manifestation, these steps are:
- Identify the variables: We must identify the factors that we can manipulate so that the result changes.
- Write our hypothesis: Establish a hypothetical result that we are going to demonstrate.
- Gather the materials: We must have all the materials and variables to be able to carry out our experiments.
- Analyze the data: When we do an experiment we must record everything we see and then analyze it to examine each step and the procedures performed.
- Write the conclusion: After analyzing the data obtained, we can write a conclusion about the experiment carried out and the result obtained.

Answer:
A - 3:1
Explanation:
In order to determine what number of offspring will have attached earlobes, we must make a Punnett table. We know that attached earlobes are the dominant gene, and we know unattached earlobes are recessive.
| P | p
——————-
P | PP | Pp |
——————-
p | Pp | pp |
As we can see, only one out of the four squares has two recessive genes. Therefore, our answer would be A - 3:1.
Every time you eat a cookie or candy bar, your blood sugar increases. This triggers an increase in the hormone insulin. Insulin<span> is a hormone made by the pancreas which allows your body to use sugar (glucose) from carbohydrates in the food that you eat, or to store glucose for future use. </span>Insulin<span> helps keeps your blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia).</span>
The pair that incorrectly matches polymer-monomer is lipids-monosaccharides (option C).
<h3>What is a monomer?</h3>
A monomer is a small molecule which can be covalently bonded to other monomers to form a polymer.
A polymer, on the other hand, is a large molecule made up of a chain of many monomeric units, formed by chemically bonding together.
The following are the monomer-polymer combination we have in nature;
- Carbohydrates - simple sugar/monosaccharide
- Protein - amino acid
- Lipids - fatty acid
- Nucleic acid - nucleotide
Therefore, the pair that incorrectly matches polymer-monomer is lipids-monosaccharides.
