Answer:

Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles (neutrons or protons). The difference in mass between the reactants and products is manifested as either the release or the absorption of energy.

The photon is a type of elementary particle. It is the quantum of the electromagnetic field including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force. Photons are massless, so they always move at the speed of light in vacuum,

photons are in light so yeah

Answer:

The correct answers are options B. "It is formed at zones of volcanic activity on the ocean floor. ", C. "It is made of all types of rocks" and E. "It contains silicate minerals high in iron and magnesium."

Explanation:

In Geology, the continental crust is defined as the layer of the Earth that allowed the formation of the continents. This layer is made of all types of rocks, including igneous, metamorphic, and sedimentary rocks. This layer is also considered silica-rich, or felsic, because of its high content of silicate minerals. Regarding the thickness of continental crust, it is between 25 to 70 km thick. This is considerable thick considering that oceanic crust which barely reaches 10 km thick.

Explanation:

Answer:

C) They may provide selective advantages.

D) Slight differences in the genetic code may have significant results.

Explanation:

The genetic code is universal, and present in most living beings . Generally, in most living organisms, the same codons are assigned to the same amino acids.  

DNA sequences make up genes that may have multiple variants, called alleles. DNA deoxyribonucleic acid, is transcribed into mRNA and then translated into amino acids that form proteins.

Natural selection mainly acts on phenotypes, which are dependent on proteins and the organisms's environment.  Phenotypes conferring advantageous traits are favored by the selection process- these help groups of organisms evolve over time.

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.

The different types of stem cells are:

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

Thus, the different types of stem cells are:

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.

Answer: The induced fit model states an substrate binds to an active site and both change shape slightly, creating an ideal fit for catalysis. When an enzyme binds its substrate it forms an enzyme-substrate complex. ... The enzyme will always return to its original state at the completion of the reaction.

Answer:

C

Explanation:

a difference in the pH of an environment changes enzymes activity

A valid conclusion from the graph is;  a difference in the pH of an environment changes enzyme activity.

An enzyme is a biological catalyst that promotes biochemical reactions in the body. Enzymes are specific in their actions. Enzymes act on particular substrates. There is an optimum pH of enzyme activity. The pH of an environment affects enzyme activity.

According to the graph shown, the activity of the enzyme is plotted against the pH of the environment. we can see from the graph that  a difference in the pH of an environment changes enzyme activity.

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:

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.

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.
