if your leg was to get cut off where would you feel the pain?

Answers

The thigh area will feel much more pain as when leg is cut off , all nerves are together in thighs, so more pain will be there.

Hope it helps you... pls mark brainliest if it helped you

Answer:

The nerve(s) in your leg.

Explanation:

It's not your leg that will hurt but the nerve in your leg. So wherever the leg is cut, the nerves will have to be cut as well, but also after one of your limbs is amputated, you may feel like the limb is still there. That's called phantom sensation. You might feel pain in your limb even though it is physically not there.

4 Which muscles are actively involved in normal breathing?

Answers

The lungs have no skeletal muscles of their own. The work of breathing is done by the diaphragm, the muscles between the ribs (intercostal muscles), the muscles in the neck, and the abdominal muscles.

Answer:

The main muscles are the diaphragm and intercostal muscles, but the muscles in the neck and the abdominal muscles also help.

Explanation:

The diaphragm is the muscle under the lungs that helps move the lungs while the intercostal muscles are the muscles in between the ribs.

Use your knowledge of Protein Synthesis, and the provided chart, to identify the
correct Amino Acid sequence from the mRNA strand: AGUUGGUCUGUA


A: serine, tryptophan, serine, valine
B: aspartic acid, valine, leucine, asparagine
C: leucine, histinde, glutamic acid, leucine
D: serine, threonine, arginine, aspartic acid

Answers

Answer:

A: serine, tryptophan, serine, valine

Explanation:

Hi there!

Protein Synthesis is the process where proteins are created from DNA.

We are given the mRNA strand AGUUGGUCUGUA, as well as a provided chart

The mRNA strand is created out of nucleotides (each of the letters is one nucleotide in the code), which will code for a specific chain of amino acids, creating a protein.

Each amino acid is made up of 3 nucleotides. This sequence of 3 nucleotides is called a codon.

So we can break up the code into groups of 3, to make identifying the codons easier.

AGU UGG UCU GUA

Now we need to figure out which amino acid each codon codes for. Thankfully, we were given a chart that can help us with that.

The chart is read where the first base is on the left, and is vertical. The second base is in the center, yet is horizontal. The third base is on the right, and is also vertical.

Let's start with the first codon, which is AGU

The first base is A. The second base is G, and the third base is U. So the first amino acid is serine (ser)

The second codon is UGG.

The first base is U, the second base is G, and the third base is G. So the second amino acid is tryptophan (trp)

The third codon is UCU

The first base is U, the second base is C, and the third base is U. So the third amino acid is serine (ser)

The fourth codon is GUA

The first base is G, the second base is U, and the third base is A. So the fourth amino acid is valine (val).

That means the amino acid sequence from the mRNA code is: serine, tryptophan, serine, valine. The answer is A

Hope this helps!

F. The monomers if starch are monosaccharides

All biological macromolecules are carbon-based molecules, the monomers of DNA are nucleotides, cell membranes, in part, are made from phospholipids and the monomers of starch are monosaccharides correct statements. Therefore, the correct options are A, B, E and F.

What are biological macromolecules?

Biological macromolecules are large molecules constituted of organic molecules. These are necessary for the survival of an organism. The four major classes of macromolecules in the study are Carbohydrates, Lipids, Proteins and Nucleic acids.

They are all built from carbon-based or organic molecules. These molecules form important components of a living cell and constitute most of its dry weight. These macromolecules are mostly obtained from the food we eat which is broken down into nutrients which are these organic molecules.

They are also called biomolecules. Carbohydrates are energy sources made of sugars. They are broken down into glucose which is required for cellular respiration to produce energy.

Proteins perform various functions including structural, regulatory, protective etc. Lipids are non-polar compounds that store energy for the long term in the form of fats in our bodies. Nucleic acids are hereditary biomolecules that pass on traits from one generation to another.

Therefore, the correct options are A, B, E and F.

In a randomized trial, scientist try to make sure that there is only one difference between the two groups. What do we call all the things that are the SAME Between the two groups?

A. Predictions
B. Controls
C. Constant
D. Variables

Answers

Hey there! I'm happy to help!

A. Predictions are guesses you make about the result of a trial. Let's say that you want to test what will happen if you put less eggs into a cookie recipe. You could make a prediction that the cookies will be more crumbly. This is not the term for things that are the same between two groups, so this is incorrect.

B. Controls are a type of variable that isn't influenced in a unique way as part of the experiment. This is to be able to compare the things you change to a thing that hasn't changed. With our cookie example, a control group would just be a cookie recipe with the normal amount of eggs. Then we can compare a normal cookie to one with less eggs. We see that a control is a type of group, and not a specific thing that is similar or different between the groups, so this is incorrect.

D. Variables are things that  can change or vary in your experiment. There are independent variables, which are things that you change, such as the number of eggs in the recipe. Then, you have dependent variables such as color, texture, taste, etc. However, these can change depending on the group because the number of eggs could switch, so this is the wrong term and incorrect.

C. Constants are things that you do not change as part of your experiment. You do not change these variables. In our case, the constants will be all of the other ingredients like the amount of flour, milk, water, sugar, etc. If we have a control group and a group with less eggs, these things will remain constant in both of them. So these things are the same between the two groups, so this answer is correct.

We call the things that are the same between the two groups C. constants.

A. mRNA strand, nucleus
B. polypeptide chain, nucleus
C. protein, cytoplasm
D. tRNA strand, cytoplasm

Answers

Answer:

A. mRNA stand, nucleus

Explanation:

Transcription is defined as the process of copying DNA. This happens so that the cell can produce the proteins necessary for basic life functions.

DNA cannot simply be taken out of the nucleus that easily. So, the DNA must be copied into a different form. That's what RNA is for, specifically mRNA.

mRNA stands for "messenger RNA", which is a copy of DNA that can be transported outside the nucleus and be read to produce proteins in ribosomes.

Transcription happens in the nucleus, where the DNA is housed in. It can't be located anywhere else anyways since DNA cannot leave the nucleus.

Therefore, our answer is A.

Which of the following best explains why Mars' and Venus' surface temperatures vary, despite both planets having atmospheres that contain mostly carbon dioxide?(1 point)

Venus has a surface of high mountains which absorb heat.
Mars has a surface of red rocks and sand which reflect heat.
Venus has a thick atmosphere which blocks heat from the surface.
Mars has a thin atmosphere that cannot hold much heat.

Answers

Mars and Venus are the planets of the solar system and vary in their temperatures. Mars has a thin atmosphere that cannot much amount of heat. Thus, option D is correct.

What is the atmosphere of Mars?

Mars has been the fourth planet of the solar system that is also called the red planet due to its red appearance. It has more amount of carbon dioxide than oxygen gas. It comprises various gases and has a thin atmosphere.

The thin atmosphere of Mars unlike Venus cannot hold the heat and transmits it back to space. Venus has a thick atmosphere that traps heat and results in an increased surface temperature. The atmospheric particle of Mars cannot retain heat and hence vary in temperature.

Therefore, option D. Mars has a lower temperature than Venus due to its thin atmosphere.

DNA and RNA are macromolecules made up of units called nucleotides.

What are nucleotides?A nucleotide is the most fundamental element of nucleic acids (RNA and DNA). A sugar molecule (ribose in RNA or deoxyribose in DNA) is bonded to a phosphate group and a nitrogen base to form a nucleotide. Adenine (A), cytosine (C), guanine (G), and thymine (T) are the bases that make up DNA. The base uracil (U) replaces for thymine in RNA. Long chains of nucleotides make up DNA and RNA molecules, which are polymers.
