Compare between tertiary and quaternary structure of protein and write in details how folding of
protein occur in each structure?
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.

Students have a small steel ball and a large steel ball, and they have a short ramp and a tall ramp.
The students want to find out if a ball's size affects how far it can roll. They also want to find out if the height of the ramp affects how far the ball can roll.
They do the following experiment:
**Written Response** What can they conclude from this experiment? Why?
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
Thank you !

How are impulses received to the brain? Step-by-step???
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.

PLSS HELP QUICH ILL GIVE 65 POINTS ty
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.
Which of the following is a true statement about extinction?
A. Extinction is the death of a species or a larger taxonomic group.
B. It is estimated that presently we are losing hundreds of species every year due to human activities.
C. It is estimated that as much as 38% of all species, including most primates, birds, and amphibians, may be in danger of extinction before the end of the century.
D. All of the statements about extinction are true.
E. Many extinctions are associated with climate change.
Answer:
Extinction is defined as the complete elimination or termination of one of a kind of organisms or different taxa, generally species. The extinction of species can be due to human activities, climate change, loss of habitats, and other natural causes. Hence, the correct option is D.
Explanation:
Extinction is the end of a certain group, taxa, phylum, or most prominently species. There are several reasons for the extinction of species or larger taxonomic group, such as human activities, the introduction of dangerous species, loss and destruction of habitats, illegal trafficking, climate change, and human activities.
Human activities such as deforestation, urbanization, and mining are some of the major causes of the loss of species and their extinction. Due to these activities, hundreds and thousands of floras and faunas are on the verge of extinction.
Approximately more than a thousand species have been extinct over the past 500 years. Almost 38 percent of the known species have been extinct or will be extinct, which includes primates, birds, animals, and amphibians. Some of the examples of extinct species are Dodo, passenger pigeon, mammoth, and Pierolapithecus.
Climate change is one of the major reasons for the loss of biodiversity. Recent research has estimated that the majority of the species will be lost over the next fifty to 50 years.

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.

Lisa will require two groups of randomly selected subjects ; each group consisting of the same number of subjects.
One group, Group A will have the Rogoti treatment applied on their hair, the other group, Group B will have the usual hair treatment applied (CONTROL GROUP). The subjects are left for a particular period of time and the growth level or rate of their hair measured.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.

A hypothesis is a plausible explanation for a particular fact, observation, or process. Write a hypothesis about how the various concentrations of acid will affect the amount of limestone that is dissolved from each jar.
The hypothesis will state as follows: IF the concentration of acid increases, THEN, the amount of limestone dissolved will also increase.
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).In this case regarding the dissolution of limestone with respect to different concentrations of acid, a possible hypothesis will state as follows:
"IF the concentration of acid increases, THEN, the amount of limestone dissolved will also increase".
