Answer:
electron transport chain
Explanation:
just took the quiz
The image shows the C. electron transport chain (ETC) step of cellular respiration
What is the electron transport chain ?The ETC is the final stage of cellular respiration, where oxygen is used to create ATP. NADH and FADH2, which are produced in the Krebs cycle, donate electrons to the ETC.
The electrons are passed through a series of proteins, which release energy that is used to pump protons across the mitochondrial membrane. This creates a proton gradient, which is used to power ATP synthase to produce ATP
The Krebs cycle and lactic acid fermentation are both earlier steps in cellular respiration. In the Krebs cycle, pyruvate is oxidized to produce NADH, FADH2, and ATP. In lactic acid fermentation, pyruvate is converted to lactate, producing NADH.

describe the possible long term effects of HIV on the immune system
Explanation:
HIV attacks a specific type of immune system cell in the body. It's known as the CD4 helper cell or T cell. When HIV destroys this cell, it becomes harder for the body to fight off other infections. When HIV is left untreated, even a minor infection such as a cold can be much more severe.

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

Proteins can be denatured in many ways.
Which of the following will NOT denature
a protein?
A. pH
B. temperature
C. too many enzymes
D. salt content
Answer:
Explanation:
However, at very high salt concentration, the increased surface tension of water generates a competition between protein and salt ions for hydration. Salts strip off the essential layer of water molecules from the protein surface eventually denaturing the protein
Too many enzymes cannot denature protein.
Enzymes are a type of protein so they will not get denatured in presence of one another.Enzymes are proteins that speed up any biochemical reaction in the body.What is denaturation of protein?It is a process of modifying the molecular structure of a protein.It involve breakage of many of the weak bonds within the protein molecule that are responsible for the structure of protein and its order.It can happen due to high temperature, pH, salt concentration and mechanical concentration.To know more about denaturation of protein here

7. Observations and inferences are
important in science. How would you
explain the difference between the
two words?
Hey there! I'm happy to help!
Observations are things that can be written down or described. You can observe something with any of your five senses: you can see what color something turns, you can hear the noise something makes, you can taste a cookie with a different amount of an ingredient, you can smell an odor produced by a chemical reaction, and you can feel the texture of different samples.
You can also create observations by using scientific tools. For example, instead of feeling if water is hot or cold, you could use a thermometer. This will give you numerical data which can be put into a table or graphed for further analyzing.
Inferences are created from observation. You cannot make an inference without observation. Observations lead to inferences. Inferences are conclusions or guesses made from the observations. You could infer that sugar makes a cookie taste sweeter after experimenting with no sugar and observing that it tasted bitter. You could infer that more weight allows things to travel further after going down a ramp after measuring the distances different weights travel, graphing it, and observing the data.

The mutation from AATTAG to AAATAG is a substitution which causes an increase in genetic variation of a population.
MUTATION:
Mutation refers to any change in the nucleotide sequence of DNA molecule. Mutation can be of different types depending on how it occurs. A substitution mutation is that in which one or more nucleotide base is replaced by another in the sequence. In this question, an original sequence of DNA is given as AATTAG. It was mutated to AAATAG via the replacement of 'T' with 'A'. This means that it is a substitution mutation. However, this mutation will cause an increase in the genetic variation i.e. difference in a population.Learn more at: https://brainly.com/question/21220597?referrer=searchResults

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.
