Which step in cellular respiration produces the most ATP?(1 point)
Krebs cycle
glycolysis
electron transport chain
lactic acid fermentation
Answer:
it's Kerbs cycle which produces most ATP in cellular respiration
Answer:
The answer is electron transport chain
Explanation:
The stage that produces most of the ATP during cellular respiration is the electron transport system (ETS) present in mitochondria.
The formation of ATP occurs by oxidative phosphorylation. Theoretically, 34 ATPs are produced in the ETS by the complete oxidation of a glucose molecule. Electrons are transferred from NADH or FADH2 to O2 by a series of carriers and are coupled to ATP synthase for the formation of ATP.

Genetic variation exists in a population leading to individuals with
adaptations with different survival frequencies.
D)
E)
Indiana is home to fossilized
The correct answers are:
-Genetic variation decreases in a population of prey after natural selection acts on it.
-Genetic variation exists in a population leading to individuals with adaptations with different survival frequencies.
Genetic variation creates new variants of a gene; such a variant is called an allele. These variations occur as a result of the interaction between individuals with their environment, where it affects them in a way that determines their survival or not, as a consequence of their adaptability to the surrounding context. Thus, natural selection occurs, which establishes which individuals survive and which individuals do not. Thus, individuals characterized as prey who develop defense elements against hunters will be the ones who survive, while those who do not will be the ones who will perish.

Overview of photosynthesis, using the detailed inner structure of a leaf.
Answer:
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.

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.

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.

A.
The mutation is a substitution which causes a decrease in the genetic variation of a population.
B.
The mutation is an insertion which causes a decrease in the genetic variation of a population.
C.
The mutation is an insertion which causes an increase in the genetic variation of a population.
D.
The mutation is a substitution which causes an increase in genetic variation of a population.
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

por que un globo con aire se agranda al sol y se achica en la heladera
Answer: El globo congelado se contrajo porque la energía cinética promedio de las moléculas de gas en un globo disminuye cuando la temperatura disminuye. Esto hace que las moléculas se muevan más lentamente y tengan colisiones menos frecuentes y más débiles con la pared interior del globo, lo que hace que el globo se encoja un poco.
Explanation:
