The statement that the integument is strictly composed of the skin and It does not include the various accessory structures that may be present on or beneath the skin layers is False.

<h3>Composition of integument</h3>

Together with the underlying epidermal cells that secrete the cuticle, the cuticle and integument make up the skin.
The cuticle functions as the insect's exoskeleton, the location of muscle attachment, and the first line of protection against fungi, bacteria, predators, parasites, and environmental toxins, including pesticides.
The integument plays a role in behavior, osmoregulation, water control, eating, excretion, desiccation resistance, and as a food reserve.
The complexity of the structure and chemistry of an insect's integument as well as the unique ways in which it has been modified to work within its owner's environment serve as some indicators of the variety of roles that these coverings play.

Turtles Ahoy! (A real implementation of the scientific method) Did you ever wonder how baby sea turtles can run down into the oc

The scientific method is a research method that involves the question and problem definition, hypothesis formulation, goals, defining variables, collecting data and analysis, discussion, and conclusion.

<h3>What are the steps of the scientific method?</h3>

There are different steps to follow in a scientific method

Previous knowledge about the study object.

Definition and problem statement. The question for which there is no answer yet. A question the investigator wants to answer.

Goal especification. The goal is what the investigator wants to know.

Hypothesis formulation. The researcher hypothesizes in order to predict what is going on or what is expected to occur.

Experiment. Different variables influencing the proyect are considered. Data collection and analysis stages. This step involves testing the observations.

Results

Discussion and hypothesis verification. This step involves the deriving of the working hypothesis.

Conclusions.

<h3>What is a hypothesis?</h3>

A hypothesis is a scientific conjecture, not verified, that requires corroboration. It must be objective. Usually, it is written in the present time.

It is a claim of how it works a relationship between two or more variables. There must be a logical relationship between the involved variables.

<h3>What are dependent and independent variables?</h3>

When conducting an experiment, we must always consider the involved variables.

Independent variables are those modified or changed by the researcher to study how this change affects another variable and hence the results. This variable is not affected by any other one but influences or causes a reaction in other variables.

The dependent variable is the one influenced by the independent variable, and is affected by any change on this last one. Its response might be either directly proportional or inversely proportional to the change in the independent variable.

In the exposed example,

1. <em>Circle and label the question that is going to be investigated</em>.

How can sea turtles orientate into the ocean after hatching, paddle thousands of miles across the North Atlantic, and find their way back years later to the same beach they were born?

2. <em>What is the hypothesis</em>?

Turtles use Earth's magnetic fields and waves to orientate themselves in the water and on the ground.

3. <em>What is the independent variable</em>?

The magnetic field orientation.

4. <em>What is the dependent variable</em>?

Direction in which the turtles swim.

5. <em>What are the constants</em>?

Large glass tank filled with water and total darkness.

6. <em>Describe the data and analysis</em>.
