WHAT IS A HYPOTHESIS?

A hypothesis is a crucial part of the scientific method. It is a testable explanation of an observation or a proposed answer to a scientific question.

A hypothesis, which must be testable via experimentation, can either be accepted or rejected depending on the outcome of the experiment.

A hypothesis is an IF, THEN statement that must include the independent and dependent variables of the experiment i.e. it must show how the dependent variable (effect) is affected by the independent variable (cause).

Answer: Various answers to this.

Explanation: Depending on where you are located on the globe, or depending on where the earth is facing, the sun's rays can differ in various different ways. Example: the closer you are to the sun's equator, the hotter it is( like Florida). But the further you are the colder it is( Like Michigan)

Answer: Yes, Yes it does!

Explanation:

Answer:

Thrust and Lift.

Method:

There are 4 forces acting upon a plane while it is moving. Drag (The air friction while it's in the air), Lift (Generated by the wings (The upward force), Weight (How heavy the plane is), and finally, Thrust (Generated by the engines which moves the plane/wings through the air generating lift). If there is enough air going over the wing at a high enough speed, and Thrust, and Lift overcome the other two forces keeping the plane on the ground, it can fly. The air pressure under the wing is higher than over the wing - If you have ever ran you hand under the water keeping it flat, you may notice it going up, those are basically the same forces, but under water.

How does the pressure under the wing affect the lift?

The difference of air pressure over the wing (which is less), which also means less force bringing the plane down. The air pressure under the wing is higher, putting pressure on the wing moving it up. A wing is designed to make the air travel a longer distance over the wing than under the wing creating the air pressure. The engines just enforce that process.

So, impulses are basically reactions from something else. So, in the brain, there are neurons, which are also known as brain cells. They have two main and really important parts, called the dendrite and the axon. The dendrite receives the impulse, either from the central nervous system (CNS) or from the peripheral nervous system (PNS). After this event, the axon transfers and carries the impulse away from the cell body. Also, the impulse travels through a little gap in between neurons called the synapse, before the impulse travels to the next neuron. And, remember, this process is not slow. This process occurs in a matter of milliseconds. Think about it. If you burn your hand from something really hot, you will react to that really fast as an impulse. Millions of neurons will react to that in just a second. That's why science is so cool. It has so many interesting topics and fascinating facts, like this. Anyways, I hope this helped you. Enjoy your day.

Dendrites get impulses. Axons carry impulses.

Answer:

Tertiary structure is formed by the folding of the secondary structure sheets or helices into one another. The tertiary structure of protein is the geometric shape of the protein. It usually has a polypeptide chain as a backbone, with one or more secondary structures. The tertiary structure is determined by the interactions and bonding of the amino acid side chains in the protein.

Answer:

I think the height of the ramp affects the distance that the ball can go, but the size doesn't affect it

and as you decrease th height of the ramp it will look like straight thing, when it look like that the ball might need a little force in order to get speed also to go far

but in this condition the size can affect the ball distance it also depends on how much you give to it

A correct scientific name for a microbial specie from the options is : ( A ) ; Staphylococcus aureus

For a correctly written scientific name for a microbial specie ( following the empirical rule ) the genus starts with a capital letter while the specie is started in small letters, also the scientific name should be Italicized as well. although there are  exceptions where the specie is started with a capital letter but it must be italicized to qualify as a properly written scientific name.

Hence from the options the correct scientific name for a microbial specie is  Staphylococcus aureus because it follows the empirical rule

The independent, dependent and control variables in the experiments given are :

1.) Group B participant who aren't given the special juice are the control group.

2.) The Independent variables are the juice types given to the participants

3.)The dependent variable is Number of stack of paper made.

4.) since the number of stacks of paper made by group A is less than that made by group B, we conclude that the special group does not increase productivity.

5.) The experiment could be improved by having a group which are not given any type of juice to drink to serve as control.

6.) The initial observation is the presence of green slime on shower.

7.) The control group is portion of the shower being sprayed with water.

8.) The Independent variables are spray and water .

9.)Dependent variable is appearance of the green slime on the shower after treatment.

10.) It can be concluded that the coconut juice treatment is not effective.

11.) The control group is the unexposed group of mouse.

12.) The Independent variable is the exposure level of the mouse

13.) The dependent variable is the ability of mouse to push block.

14.) We cannot expressly conclude that mouse exposed to microwave are stronger as the output values are very close

15.) To improve the experiment, Bart may increase the sample size.

16.) Test subject A, sprayed with the original itching powder is the Control group.

17.) The Independent variables are the types of itching powder.

18.) The dependent variable is the itching time.

19.) Since subject B upon which the experimental itching powder is applied experienced longer itching time of 45 minutes, hence, the data supports the advertisement claim.

20.)

Lisa will require two groups of randomly selected subjects ; each group consisting of the same number of subjects.

The Independent variable = hair treatment (Rogoti and the usual hair treatment)

The dependent variable = growth rate

The control group in an experimental study refers to the group of participants who aren't given the treatment.

The Independent variable are variables in an experiment which are manipulated in other to effect changes in the dependent variable.

The dependent variable are variables which are measured in an experiment. They are the variables upon which manipulation of independent variable are being measured.

carbonic anhydrase helps to maintain the acid-base balance in the bloodstream and is present in high concentration in erythrocytes

Explanation:

As degrees of CO2 in the blood begin to upward push, the body can reply through hyperventilation or hypoventilation, respectively. The CO2 is sure to hemoglobin paperwork a carbamino compound. In circumstances in which the CO2 and H+ concentrations are excessive, the affinity of hemoglobin for O2 is reduced.

The blood consists of carbon dioxide to the lungs, where it's miles exhaled. As carbon dioxide accumulates in the blood, the pH of the blood decreases (acidity will increase). The mind regulates the quantity of carbon dioxide that is exhaled by controlling the rate and depth of respiration (airflow).

The carotid frame represents an international oxygen-sensing mechanism in mammals. whilst the glomus cells within the carotid frame locate hypoxia, they may be depolarized and ship signals to the respiratory centers within the medulla oblongata to boom respiration price.
