A hypothesis is a claim the researcher makes to stablish a relationship between variables and predict the results of the experiment or explain what thinks is going on. Note: Since I did not find the options, I provide examples below.

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

When following the scientific methodology, researchers must formulate a hypothesis.

A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, not a fact. It is a claim of how it works a relationship between two or more variables.

The researcher hypothesizes to predict what is going on or what is expected to occur.

A hypothesis

• must be clear and comprehensive.

• must express the direct relationship between the involved variables.

• must be objective.

• must be testeable and falsifiable

There are different kinds of hypotheses: descriptive, correlative, differentiative, or causative

Question: "Are black-tailed prairie dogs dying to sylvatic plague and causing the population to decline?"

The variables involved in this question are,

  • Independent variable: sylvatic plague presence
  • Dependent variable:  black-tailed prairie dogs survival or death.

                                            population size change

<u>Note</u>: Since I did not find the complete question, I will propose a few potential Hypothesis as examples for you to understand the structure.

Hypothesis:

If black-tailed prairie dogs are exposed to <u>sylvatic plague</u>, then their <u>mortality rate</u> will increase, declining their population size.

If black-tailed prairie dogs are exposed to <u>sylvatic plague</u>, then their <u>survival rate</u> will decrease, declining their population size.

If black-tailed prairie dogs are exposed to <u>sylvatic plague</u>, then their <u>population size</u> will decline.

Another alternative is to think that variables are,

  • Independent variable: black-tailed prairie dogs dying to sylvatic plague or to other causes
  • Dependent variable: Population size change

Hypothesis:

If black-tailed <u>prairie dogs are dying to sylvatic plague</u>, then their <u>population size </u>will decline.

Notice that in every case, you can mention first the independent variable and the effect it provokes on the dependent variable.

Answer: The only reaction performed by chloroplast through its chlorophyll is photosyntesis. Therefore the chemical formular is below.

   C02         +          H20           →                   C6H1206    +       O2+           H20.

(carbondioxide) +    (Water)     Chlorophyll      (glucose)  +(oxygen)+     (water)

                                                       and                                                                                            

                                                   enzymes .                    

This is the single reaction of the process of photosynthesis.However two interconnected reactions are involved light dependent stage and light independent stage.

The first reaction takes place in presence of sunlight, and it is called Photolysis of water.it is the spiting of water to H+, electrons and Oxygen. This is  the source of oxygen seen above.

             4 H20→ 4H+ + 4e- + 02.

The light independent stage; the hydrogen ion from the photolysis is transfer to the light independent stage to reduce the C02 to produce glucose.In the first equation seen above.

Since chloroplast performs photosynthesis through action of its chlorophyll, The above reaction describes the chemical formula.

B.

The cell wall  of plants is made up of the middle lamella, the primary cell wall and the secondary cell wall .

<u>Cellulose</u><u> a complex carbohydrate is the major components</u>. It contains,  monomers of  glucose in small units  linked to one another by bonds.

C

Vacuole helps in plant turgidity needed for uprightness. when filled with water provides  turgor pressure increases as the cell membrane pushes against the cell wall. The resulted turgidity  helps the plants  to maintain resistance to external pressure and therefore resist the effects of gravity.

Which wavelength in photosynthesis which has the highest amount of energy?
algol13
Violet and blue have the high frequencies (thus energy) of visible light. Red will be the least energy but lowest energy. And remember, chlorophyll is green because it reflects green into our eyes. Green is therefore not absorbed, so not used for photosynthesis.

The endocrine system regulates the body through hormone release. Like the nervous system, what does the endocrine system help ma
Oliga [24]

Answer:

How is the endocrine system related to the nervous system in terms of its regulatory activity?

For one, the endocrine system uses chemical signaling (hormones, produced by glands) while the nervous system uses electrical signaling (neural impulses). The signal transmission of the nervous system is fast because neurons are interconnected, but the functions are more short-lived.

Which cellular communication appears to be signaling between cells that are separated by long distance?
Fudgin [204]
Endocrine Signaling
Signals from distant cells are called endocrine signals; they originate from endocrine cells. In the body, many endocrine cells are located in endocrine glands, such as the thyroid gland, the hypothalamus, and the pituitary gland.

Papessa [141]
<span>The answer to this question would be: tissues; decrease

Oxygen is delivered to the tissue by the heart. It will be unloaded in the tissue, causing the oxygen level in the blood to be decreased. After that, the blood also picks up the carbon dioxide so its level will be increased. 
In lungs, the carbon dioxide will be unloaded and oxygen will be loaded back into the blood.</span>
