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

A pair of fruit flies reproduces and has 1000 offspring. All 1000 offspring have the alleles Gg. What is the most likely combination of alleles that each parent has, and why are other combinations not likely.
Answer:
The correct answer would be - GG and gg.
Explanation:
As it is given that all the 1000 offspring having the same allele Gg which is only possible in one condition that is cross between GG and gg because it is a heterozygous condition in the offspring. So there must be both allele present and it can not be heterozygous parents as there would be a different combinations of offspring in that case.
If the parents either GG only all the offspring would be GG the same with gg than all the offspring will be gg, thus the correct answer would be GG and gg.

Nucleotides are to ___
as ____
are to proteins.
O nucleic acids; amino acids
O amino acids; polypeptides
O genes; enzymes
O polymers; polypeptides
Answer:
Your answer is A). Nucleotides make up nucleic acids like DNA and RNA, and a protein is a chain of amino acids.
Nucleotides are to nucleic acids as amino acids are to proteins.
In the given fill-in-the-blanks, we are required to determine and identify which parts correspond with the given words.
Nucleotides are a "nucleoside and a phosphate" combination constituting the monomeric unit of nucleic acids. They have numerous metabolic roles and are also essential for DNA replication and RNA transcription. Amino acids are the building blocks of proteins and are an important component of our bodies. As given above, we can now ascertain that nucleotides and nucleic acids are related while amino acids are to proteins.With the requirement to join the corresponding 'elements' with each other, we can understand and identify the words and the blanks by determining the constituent of each element. And by doing that, we can safely say that nucleotides make up nucleic acids like amino acids are for proteins. Thus, the correct answer is the first option.

Answer: a. energy!!!
Explanation:
It's me again!! Hope this helped!! :D
Answer:
Sugar
Explanation:
I am not completely sure but correct me if I am wrong. Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.

Which region is located between 60-90N and 60-90S?
Mid-Lats
Polar
Tropics
Tropical Rainforest
Answer:
The correct option is Polar
Explanation:
The polar region/arctic are located/extend from 66.5 degrees N (north) and also S (south) latitude to the north and south poles of the earth. From this, it can be deduced that the polar region is located between 60-90 degrees of N and 60-90 degrees of S. Polar regions are far from the equator as a result of this and are characterized by very low solar radiation.
Polar or artic region is located between the coordinates 60-90N and 60-90S. The polar regions are extremely far away from the equator, which is situated at 0-degrees latitude.
The correct answer is:
Option B. Polar
The polar region is defined as the region situated 60-degrees north or south of the equator. The solar radiation in the polar region ranges from only 18 hours and 5 hours during winters.
The middle latitudes are situated between 30N and 30S of the equator. It is characterized by moderate sunlight.
Tropics or tropical rainforests are situated near the equator and usually experience a warm climate.
Therefore, option B is correct.

Predict how a lack of resources (food, water, shelter) would influence population size. Do you think the lack of availability would increase or decrease the size of a population? Why?
Answer:
a lack of resources would most likely decrease a population size because it will limit growth and decrease survival rates. There will also be more competition.

Which term applies to muscle cell
A) prokaryotic
B) eukaryotic
C) unicellular organisms
D) stem cell
Stem cell term applies to muscle cells.
What are the functions of stem cells?Stem cells are the cells that develop into blood, brain, bones, and all of the body's organs. They have the potential to repair, restore, replace, and regenerate cells, and could possibly be used to treat many medical conditions and diseases.
While they can regenerate themselves in an animal or person they are generally very difficult to grow and to expand in the laboratory. Because of this, it is difficult to obtain sufficient numbers of many adult stem cell types for study and clinical use.
Stem cells originate from two main sources: adult body tissues and embryos. Scientists are also working on ways to develop stem cells from other cells, using genetic “reprogramming” techniques.

1. Clasifica las siguientes sustancias según se trate de nutrientes o productos resultado de la nutrición animal. Razona tu respuesta. residuos orgánicos - alimento - O2 - CO2 2.
Answer:
1. Nutrientes:
- alimento
- oxígeno (O2)
2. Productos de la nutrición animal:
- residuos orgánicos
- dióxido de carbono (CO2)
Explanation:
Los alimentos son sustancias químicas que los animales ingieren a fin de que el organismo transforme dichos compuestos en nutrientes los cuales son requieridos para la generación, el crecimiento y la reconstrucción de células y tejidos.
El oxígeno (O2) es un nutriente escencial para la vida el cual se absorbe mediante el proceso de respiración. Este proceso posibilita la absorción de otros nutrientes obtenidos a través de la alimentación.
Los residuos orgánicos representan productos de la nutrición animal los cuales se descomponen naturalmente para formar parte de la materia orgánica. En animales, los desechos órganicos son eliminados a través de los excrementos o en la orina.
El dióxido de Carbono (CO2) es un producto de la respiración. En animales, la respiración celular consume oxígeno y compuestos orgánicos con el objetivo de producir energía en forma de ATP. Como concecuencia del proceso de respiración, los animales liberan CO2 al medio ambiente.

How do vaccinations work to provide immunity? and What body system regulates blood glucose levels? (For a Biology exam)
Thanks :)
Answer:
it trains the body immunity towards certain diseases
Explanation:
first of all we humans have two types of wbc cells phagocytes & lymphocytes. phagocytes produces pseudopodia which is like cytoplasm that traps or catches bacteria or viruses. lymphocytes produces chemical antibodies which destroy the viruses or bacteria by attaching to the virus and burst it out. Now when u get vaccinated u train those wbc cells for future viruses and hepl them to make antibodies to defend the body.
The blood glucose gets regulated by production of insulin in pancreas to maintain proper amount of glucose in the body
