What would happen to the concentrations of
Pyruvate, NADH and intermembrane H+ if the ETC
stopped working?
Answer:
Stay the Same, Increase, Decrease
Explanation:
Glycolysis produces pyruvate which is functioning normally if only the ETC (electron transport) stopped working because the ETC happens AFTER glycolysis, hence pyruvate is being produced and used at a normal rate (no change). NADH is produced in the cellular respiration stage PRIOR to the ETC so it is being created at a normal (or average) rate, however, it is not being used and split properly (meaning, not enough) in the ETC stage hence it's concentration increases. H+ decreases because it cannot be made if the prior step(s) were not complete.
What would happen to the concentrations of pyruvate, NADH and intermembrane H+ if the ETC stopped working are:
Pyruvate would stay the same and not be affected.that is it would remain the same.NADH would increaseH+ in the intermembrane would decrease.The concentration of the Pyruvate would not be affected If ETC stopped working and so this will make NADH would increase. Due to the fact that there is no electrons been transported down the chain, so therefore, no H+ would be moved and this in turn would make the concentration of H+ in the intermembrane space to reduce.Conclusively, we can therefore say that what would happen to the concentrations of pyruvate, NADH and intermembrane H+ if the ETC stopped working are:
Pyruvate would stay the same and not be affected.that is it would remain the same.NADH would increaseH+ in the intermembrane would decrease.Learn more from

Nucleic acid segments and ar
DNA and RNA are nucleic acids that can store biological information based on the sequence of their nucleotide monomers. Figure 1 shows a short segment of each of the two types of nucleic acids. Which of the following best describes a structural difference between DNA and RNA?
A. DNA contains four types of nitrogenous bases, whereas RNA contains only two types of nitrogenous bases
B. The backbone of DNA contains deoxyibose, whereas the backbon e of RNA contains ribose.
C. A DNA molecule is composed of two parallel strands with the same 5'-3' directionality, whereas an RNA molecule is composed of only one strand
D. Phosphate groups provide rigidity to DNA, but RNA is flexible and contains no phosphate groups
Answer:
B. The backbone of DNA contains deoxyibose, whereas the backbon e of RNA contains ribose.
Explanation:
A. DNA contains four types of nitrogenous bases, whereas RNA contains only two types of nitrogenous bases - this is false. Both contain four types of nitrogenous bases. DNA contains cytosine, guanine, adenosine and thymine, whereas RNA contains cytosine, guanine, adenine, and uracil.
B. The backbone of DNA contains deoxyibose, whereas the backbon e of RNA contains ribose. - this is true, each nucleotide in DNA contains a deoxyribose sugar, whereas each nucleotide in RNA contains a ribose sugar
C. A DNA molecule is composed of two parallel strands with the same 5'-3' directionality, whereas an RNA molecule is composed of only one strand - this is false. DNA is composed of 2 strands, and RNA is composed of one, but the DNA strands run in an anti-parallel configuration (one runs 5'-3', the other runs 3'-5')
D. Phosphate groups provide rigidity to DNA, but RNA is flexible and contains no phosphate groups - this is false, both DNA and RNA nucleotides contain phosphate groups

6H2O has _ hydrogens total.
Answer:
12
Explanation:
6H2O or hexahydrate is a group of 6 water molecules or 6 molecules of dihydrogen monoxide. When looking for the total particular number of elements in a substance, find the subscript or smaller number in front of that atom, and look out for the coefficient or bigger number of the whole substance, and multiply that coefficient by the subscript to find the total atoms of that element.
Since there are 2 hydrogen's in each molecule of water, 6 molecules would make that a total of 12 hydrogen's for 6 molecules of water.
which process produces large amounts of energy in a star by combining lighter elements into a heavier element
Answer:
Fusion
Explanation:
A star's energy comes from the combining of light elements into heavier elements in a process known as fusion, or "nuclear burning". It is generally believed that most of the elements in the universe heavier than helium are created, or synthesized, in stars when lighter nuclei fuse to make heavier nuclei.
Answer:
Nuclear fusion

A scientist concludes that genetic inheritance of a mutated (changed) gene, such as a gene change that creates different-colored organisms in a population, is more beneficial to an organism over time and contributes to biological fitness. Discuss why a scientist would make that claim.
Answer:
If there is a change in the gene, this can further create a new generation of organisms with this change. With certain changes, it enables organisms to survive in other conditions.

What type of organism did Skou use to study the sodium potassium pump because they had large nerve fibers?
a) Rats
b) Human
c) Lady bugs
d) crabs
please help <3
Answer:
D.
Explanation:
I looked it up and the first thing I saw was Crabs. I hope this answer helps. :)
By continuously maintaining a state of disequilibrium between the concentrations of Na+ and K+, the sodium-potassium pump regulates the membrane potential of the neuron. He's working with the membranes of crab nerve cells. Thus, option D is correct.
What sodium potassium pump do?Na-k pump controls the levels of Na+ and K+ throughout the cell membrane.
The concentrations of Na+ and K+ are higher on the inside and outside the cell, respectively, when the cell is at resting membrane potential.
When various ions pass across the neuron membrane, action potentials are produced. Sodium channels first open as a result of a stimulation.
Sodium ions rush into the neuron because there are far more of them on the outside, and because the inside of the neuron is negative in comparison to the outside.
Therefore, crab nerve cells use to study the sodium potassium pump.

Warm-Up: What does it mean to be a prokaryotic cell? What
does it mean to be a Eukaryotic Cell? Which one came first?
(Think about the root words)
Answer:
eukrayotic cell l guess
Explanation:
A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid (Figure 1).
Unlike Archaea and eukaryotes, bacteria have a cell wall made of peptidoglycan, comprised of sugars and amino acids, and many have a polysaccharide capsule (Figure 1). The cell wall acts as an extra layer of protection, helps the cell maintain its shape, and prevents dehydration. The capsule enables the cell to attach to surfaces in its environment. Some prokaryotes have flagella, pili, or fimbriae. Flagella are used for locomotion, while most pili are used to exchange genetic material during a type of reproduction called conjugation.
Eukaryotic Cells
In nature, the relationship between form and function is apparent at all levels, including the level of the cell, and this will become clear as we explore eukaryotic cells. The principle “form follows function” is found in many contexts. It means that, in general, one can deduce the function of a structure by looking at its form, because the two are matched. For example, birds and fish have streamlined bodies that allow them to move quickly through the medium in which they live, be it air or water.
A eukaryotic cell is a cell that has a membrane-bound nucleus and other membrane-bound compartments or sacs, called organelles, which have specialized functions. The word eukaryotic means “true kernel” or “true nucleus,” alluding to the presence of the membrane-bound nucleus in these cells. The word “organelle” means “little organ,” and, as we learned earlier, organelles have specialized cellular functions, just as the organs of your body have specialized functions
