Thanks!

Explanation:

Vitamin D is the sunshine vitamin that has been produced on this earth for more than 500 million years.

Vitamin D is the sunshine vitamin that has been produced on this earth for more than 500 million years.During exposure to sunlight 7-dehydrocholesterol in the skin absorbs UV B radiation and is converted to previtamin D3 which in turn isomerizes into vitamin D3.

Answer:

Horses slowly developed over time.

Explanation:

The diagram shows the evolution of horses - how they slowly developed over time. Just like humans and other species, they didn't appear suddenly. They had to go through many stages of development, from the existence of the hyracotherium, their extinct ancestor, to today.

The rest of the options are incorrect as:

Answer:

Atoms themselves are composed of three different types of particles—protons, neutrons, and electrons. A proton carries one unit of positive† charge (Dufay's vitreous electricity) and an electron carries one unit of negative charge (Dufay's resinous electricity). A neutron carries no charge; it is neutral.

Answer:

During the cell cycle, the transition of DNA from its free form to chromosome is beneficial because it allows the equitable division and transmission of genetic information to the daughter cells.

Explanation:

In eukaryotic cells, DNA contains all the genetic information of an individual and is found in the cell nucleus. The way the DNA is found while the cell is in interphase —period without division— is free form, associated with histone proteins, called chromatin.

When cell division occurs, the DNA must replicate and right at the beginning of the division process the chromatin condenses, forming chromosomes. These chromosomes contain the genetic information compartmentalized into genes, making it easier to distribute it equally to each daughter cell.

The main benefit of the condensation of chromatin - nuclear DNA - into chromosomes is to achieve the equitable distribution of genetic information and its transmission to each daughter cell.

Answer:

A.) Hydration

Explanation:

hydrolysis is when you pass a current through water and break the molecules apart, abrasion is using an abrasive to cut material off, and deflation is taking a gas out of something. also if you think about how they word it, the waters kinda dissolving the rocks, what's another way to describe something dissolving in water, or soaking it all up...hydration

Answer:

Hydration

Explanation:

During hydration, water molecules are added to existing bonds without breaking them. Hydrolysis breaks the existing bonds. Deflation and abrasion are processes related to wind erosion.

Explanation:

Enzymes bring reactants together so they don't have to expend energy moving about until they collide at random. Enzymes bind both reactant molecules (called the substrate), tightly and specifically, at a site on the enzyme molecule called the active site

The site on the enzyme at which reactants are brought together during a chemical reaction is known as the active site.

Enzymes may be defined as biocatalysts that increase the rate of a chemical reaction without being consumed or changed in the overall process. It may be thought that all cellular reactions and processes are mediated by enzymes.

The construction of the enzyme-substrate complex is the first step in the mechanism of enzymatic catalysis. In this step, the reactant molecules are brought together during a chemical reaction. These reactant molecules bind to the active site of an enzyme.

The Active site of an enzyme is the region where substrates bind and catalysis initiates.

Therefore, the active site is the region on the enzyme at which reactants are brought together during a chemical reaction.

Answer:

The Triceps Brachii muscles are located on the back of the humerus and more commonly referred to as the triceps. They derive their name from a Latin phrase meaning “three headed arm muscle”, due to the fact that the triceps muscles have three muscle heads and therefore have three separate origin attachment points.

Explanation:

A nuclear reactor is an installation capable of initiating, maintaining and controlling the chain fission reactions that take place in the reactor core, consisting of the fuel, coolant, control elements, structural materials and moderator in the case of nuclear thermal reactors.

The core is the part of the reactor where the nuclear chain reaction is produced and maintained.

Components of the core:

The fuel of a nuclear reactor is fissionable material.

Control rod beams provide a rapid means of controlling the nuclear reaction, allowing rapid changes in reactor power and eventual shutdown in case of emergency.

The neutrons produced in fission have a high energy in the form of velocity. Their speed should be reduced to increase the probability of other atoms fissioning and not to stop the chain reaction. This is achieved by elastic collisions of the neutrons with the nuclei of the moderator.

Most of the energy released by fission is in the form of heat. To be able to use this, a refrigerant must pass through the interior of the reactor that absorbs and transports this heat.

In a nuclear chain reaction, a certain number of neutrons tend to escape from the region where it is produced. This neutron leakage can be minimized by the existence of a reflecting medium, thus increasing the efficiency of the reactor.

When the reactor is in operation, a large amount of radiation is generated. Protection is needed to isolate the installation workers from radiation caused by fission products. Therefore, a biological shield is placed around the reactor to intercept these emissions.

A breeder reactor is a nuclear reactor that generates more fissile material in the fuel than it consumes. Considered highly attractive because of their superior fuel economy: a normal reactor consumes less than 1% of the natural uranium that starts the fuel cycle, while a 'breeder' can burn it almost completely. It also generates less waste for the same amounts of energy. Breeders can be designed to use thorium, which is more abundant than uranium. Currently, there is renewed interest in both breeder designs due to the increased price of natural uranium.

All commercial reactors breed fuel, but they have low (though still significant) breeding ratios when compared to machines that are traditionally considered breeders. In recent years, the commercial energy industry has been emphasizing high burn fuels, which last longer in the core of the reactor.

Reproduction of fissile fuel is a common feature in reactors, but commercial reactors are not optimized for this feature which is referred to as improved burning. Up to one-third of all electricity produced in the current U.S. reactor inventory comes from reproducible fuel, and the industry is working hard to increase that percentage over time.

The advantages are:

Generates a large amount of electricity

No production of greenhouse gases

Dependence on oil is reduced

Less damage to the environment

A major disadvantage is the difficult management of the nuclear waste generated.

Nuclear power plants have a limited lifetime. The investment for the construction of a nuclear plant is very high.
