Answer:
B
Explanation:
Guanine and Cytosine pair together. So, if 32 percent is guanine, then 32 percent should also be cytosine. This is a total of 64 percent. The remaining 36 percent is split between thymine and adenine. So, Thymine will have half of 36 percent which is 18 percent.
What is the polymer for a nucleotide?
Answer:
DNA which is a nucleic acid
Explanation:
DNA is a polymer. The monomer units of DNA are nucleotides, and the polymer is known as a "polynucleotide." Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group.

Analyze the diagram below:
According to the model represented in the diagram, which of the following would cause the cell to not express the lacZ, lacY, and lacA sequences?
Binding the RNA polymerase to the gene
Preventing the repressor from binding to the lac operon
Removing the inducer
Transcribing the lacl sequence
Answer:
Transcribing the lacl sequence
Explanation:
lacZ, lacY, and lacA sequences are the structural genes, which needs to be expressed in order to produce their proteinous enzymes required for the breaking down of lactose sugar. The transcription of these three genes must occur with the aid of RNA polymerase binding to them.
However, a gene sequence called lacI encodes information for an repressor, which when expressed can inhibit the expression of the genes lacZ, lacY, and lacA. Hence, the TRANSCRIPTION OF THE LACL SEQUENCE cause the cell to not express the lacZ, lacY, and lacA sequences.
Answer: removing the inducer
Explanation: all sequences need an inducer present in order for them to be expressed

True or false, the more lean muscle mass, the more responsive your body will be to insulin.
Answer:
True
Explanation:
A general misconception is that insulin is only involved in energy and fat metabolism. When energy needs are high, insulin transports sugar from the blood into the muscle where it can be converted into energy. When energy needs are low, insulin facilitates the conversion of excess sugar into fat where it can be stored for future use.
What is often overlooked is the powerful effect of insulin on stimulating muscle protein growth and repair. An essential action of insulin is to increase the transport into muscle of amino acids, the building blocks of protein, where they can be used for rebuilding and repair. Insulin’s anabolic effects do not end there. Insulin also plays an important role in turning on one of the metabolic switches that control protein synthesis.
This action explains why combinations of carbohydrate and protein are far more effective in stimulating protein synthesis than protein alone. Two switches are responsible for turning on protein synthesis. One is activated by protein, specifically amino acid levels in the blood, and the second by insulin. Consuming carbohydrate (which raises insulin levels) and protein in your recovery drink gives you a dual benefit. In fact, research has shown that a carbohydrate protein drink is 38% more effective than a protein drink in stimulating muscle protein synthesis post exercise.
Another important effect of insulin is inhibition of protein breakdown. At any given time, muscle protein is in a state of flux – it is being synthesized and broken down. When more protein is synthesized than broken down, you have a net gain in lean body mass. After exercise, protein degradation is higher, primarily because during extended endurance activity up to 20% of the working muscle’s energy is derived from protein. That’s why consuming protein in your sports drink offers significant advantages. It reduces the amount of muscle protein used for energy. Higher breakdown rates of protein after exercise increases muscle soreness and slows the overall recovery process. By inhibiting protein breakdown, insulin mediates a faster recovery.
The bottom line – by taking advantage of how and when insulin works and how nutrition can affect insulin activity, endurance athletes can optimize muscle recovery and achieve significant improvements in endurance performance.

It takes 10 000 calories to raise 10 000 grams of water 1 degree
so 20 degrees x 10 000 grams = 2 000 000 calories.
The same type calculations can be done for heat in joules
10, 000 grams x 4.186 joules x 20 degrees. = 8372000 joules.
If the temperature of the ice-salt mixture decreases, why is the ice melting
Answer:
Salt lowers the freezing point of water via freezing point depression. ... When salted ice melts, the water can't refreeze as readily because the saline isn't pure water anymore and because the freezing point is colder. As more ice melts, more heat is absorbed, bringing the temperature down even lower.

The continuum below shows the development of the human embryo into an adult and the types of stem cells involved.
List the four types of stem cells, give an example of each type, and explain how much each type can differentiate.
The different types of stem cells are:
Totipotent Stem CellsPluripotent Stem CellsMultipotent Stem CellsUnipotent Stem CellsWhat are Stem cells?Stem cells are defined as the raw material of the body through cells from which all other cells with specialized functions are generated. Stem cells live in the bone marrow, the spongy center of some bones, where they divide to make new blood cells.
Once blood cells have matured, they leave the bone marrow and enter the bloodstream, while a small number of immature stem cells also enter the bloodstream.
Types of stem cells:
1. Totipotent Stem Cells can differentiate into any type of cell in human body or placenta. Example: fertilized egg
2. Pluripotent Stem Cells can differentiate into any type of cell in the human body. Example: Blastocyst cells
3. Multipotent Stem Cells can develop into more than one type of cell but they are more limited than pluripotent cells. Example: Blood stem cell
4. Unipotent Stem Cells can only differentiate into a single lineage. Example: Skin stem cells

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.

What would most likely happen to a person who is not getting enough essential amino acids in his or her diet?
The body would synthesize the amino acids.
Muscle growth and repair would be limited.
Stored protein would break down.
The formation of proteins would increase.
Answer:
Muscle growth and repair would be limited
Explanation:
plz give me brainiest
Essential amino acids are the vital nutrients required by the body. The deficiency of the amino acids in the diet will limit the growth and repair of the muscles. Thus, option B is correct.
What are the essential amino acids?Essential amino acids are the amino acids that are not synthesized by the body and instead are taken from external sources in the diet. Some of the essential amino acids include histidine, lysine, valine, phenylalanine, etc.
The essential amino acids improve the musculoskeletal and the immune system along with stimulating the growth and production of hormones.
If the diet lacks the essential amino acids then the repair mechanism and the growth of the body will be limited as they are not synthesized by the body.
Therefore, the absence of essential amino acids limits muscular growth and repair.
