Rearrange the sentences into their most logical sequence to describe the process of energy extraction from glucose
Pyruvic acid passes from the cytoplasm into the mitochondrion.
A series of reactions break and rearrange carbon bonds to release energy and carbon dioxide.
Three molecules of ATP are produced with every pair of high-energy electrons that pass through the electron transport chain.
In total, about 36 ATP molecules are released from one molecule of glucose.
A small amount of energy is released when the bonds in a 6-carbon glucose are broken and rearranged into 3-carbon pyruvic acid molecules.
Answer:
A series if reaction break and rrarrange csrbon bonds to release energy ang carbon dioxide.
The correct sequence of energy extraction from glucose is 5, 1, 2, 3, 4 to complete the oxidation of glucose.
What is glycolysis?Thus, the phases of cellular respiration should be performed in the following order: Krebs cycle, oxidative decarboxylation, electron transport chain, and oxidative phosphorylation are the steps in glycolysis.
The process of energy extraction from glucose:
When the bonds in 6-carbon glucose are broken and reorganized into 3-carbon pyruvic acid molecules, a little amount of energy is produced. Pyruvic acid enters the mitochondrion from the cytoplasm.
Carbon bonds are broken and rearranged in a sequence of events that release energy and carbon dioxide.
Every pair of high-energy electrons travels through the electron transport chain resulting in the production of three molecules of ATP. One glucose molecule releases roughly 36 ATP molecules in total.
Therefore, the process of energy extraction from glucose start from pyruvate forming and end with the ATP formation.

The Correct choice is ~
A. hypertonic solutionIn a hypertonic solution, the concentration of liquid is higher in the solution as compared to that of concentration in the cytoplasm of cell, Therefore Osmosis takes place, causing the liquid present in the solution to move in the cell, and hence inflammation/ swelling occurs.

Which codon is the code for the amino acid valine (Val)?
Answer: A. GUC
Explanation:
Looking at the codon chart, we see that on the lower left corner (where first base in codon is G) the whole section matches to amino acid valine. Therefore, GUU, GUC, GUA, and GUG are all correct answers, but since GUC is the only correct choice in the four choices given, GUC is the answer to this question.

Explain what TWO forces cause Earth’s water to bulge?
Answer:
Gravity and inertia act in opposition on the Earth's oceans, creating tidal bulges on opposite sites of the planet. On the “near” side of the Earth (the side facing the moon), the gravitational force of the moon pulls the ocean's waters toward it, creating one bulge.
5. a. What technology produced the results illustrated here, and what is this
technology used for? (1 point)
Think about the methods used to analyze DNA.
The technology that was used to produce the results illustrated in the image is gel electrophoresis and it is used for separating deoxyribonucleic acid (DNA) fragments.
Gel electrophoresis can be defined as a technology that is used in the laboratory for the separation of mixtures of deoxyribonucleic acid (DNA), ribonucleic acid (RNA) or other macromolecules such as proteins based on molecular size and charge.
In gel electrophoresis, an electric current is applied to the deoxyribonucleic acid (DNA) samples so as to create fragments that can be used to compare the various samples of deoxyribonucleic acid (DNA).
The steps involved in gel electrophoresis include the following:
Extraction of deoxyribonucleic acid (DNA).DNA isolation and amplification.Addition of deoxyribonucleic acid (DNA) to the gel wells.Application of an electric current to the gel.The separation of DNA bands based on molecular size and charge.Deoxyribonucleic acid (DNA) bands are stained.Read more: https://brainly.com/question/10413501

Your topic (Nutritional blog post) explain the benefits of having proper nutrition and why should we do it. List down items we may sacrifice (ex. eating junk food) but the good effects this will bring us. Cite what will happen if we have healthy nutrition and back it up with evidence (Ex. A professional science study in 1993 has found that people who have healthy nutrition are less likely to disease [THIS IS ONLY EXAMPLE!]) Next, recommend some healthy foods or make a nutritional health diet for all the days in the week, balancing carbohydrates and giving the right amount of nutrition and calories.

A single base substitution mutation is likely to have a less deleterious effect when the base change exhibits which of the following results
A single base substitution mutation will be the least likely to cause a deleterious effect when the base change produces the same amino acid as the original.
What is a silent mutation?This scenario is what we call a silent mutation. What this means is that the mutation is almost undetectable due to its not affecting the protein that it will help to form.This is possible thanks to how the genetic code operates, different codons are able to code for the same amino acid.Therefore, there are mutations that do not affect the amino acid or the protein.Therefore, we can confirm that a mutation will have no negative effects if it is a silent mutation, meaning that the substitution of a base pair happens to code for the same amino acid as the original.

Explanation:
scientists often test their hypotheses with controlled experiments. which of these is a rule for conducting a controlled experiment?
a. change at least two variables at a time
b. keep all variables constant
c. change as many variables as possible
d. change only one variable at a time
Changing only one variable at a time is a rule for conducting a controlled
experiment.
Controlled experiment involves the use of dependent and independent
variables . Changes in the independent variable brings about a
corresponding change in the dependent variable which is then recorded.
It is however important to note that changing more than only one variable at
a time won't accurately determine if the changes in the results were as a
result of one cause. This is why only one variable has to be changed at a
time.
