Fluoride levels will be higher in bone of the individuals with osteosarcomas.

What are the uses of fluoride ?  

Fluoride is a group of compounds which is a combination of fluorine and other elements, these compounds are present in water, plants, rocks, air, and soil.

Some of fluoride compounds are sodium fluoride, stannous fluoride, and fluoride mono-fluorophosphate.

Once fluorides are absorbed inside the body, it travels into the blood through the digestive tract, tend to collect in areas with high calcium like  bones and teeth.

Majorly fluorides are used in drinking water, beverages, food, and  dental products, mostly fluoro-silicic acid, sodium fluorosilicate, and sodium fluoride forms are added to water.

Some of the fluoridated water used to prevent tooth decay, and  avoid  dental fluorosis, a cosmetic condition.

Average number of decayed, missing, or filled teeth in children reduced by application of this water and  cavities in adults.

The first phase is interphase, during which the nucleus divides and the DNA replicates. The second phase is mitosis, during which the cytoplasm divides. The third phase is cytokinesis, during which the cell divides into two daughter cells.

What is cell cycle ?

The cell cycle is the series of events that take place in a cell leading to its division and duplication. It consists of two major phases: interphase and the mitotic phase. The mitotic phase is further divided into two stages: mitosis and cytokinesis.

During interphase, the DNA of the cell is replicated in preparation for cell division. This phase is divided into three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).

During G1, the cell grows and prepares for DNA synthesis. During the S phase, the DNA is replicated, resulting in two identical sets of chromosomes. Finally, during G2, the cell prepares for mitosis.

After interphase, the cell enters the mitotic phase. During mitosis, the replicated chromosomes condense and line up at the center of the cell. The nucleus then divides into two identical nuclei, each with a complete set of chromosomes.

After mitosis, cytokinesis occurs, which is the process by which the cytoplasm divides, separating the two daughter cells. The cytoplasmic division usually occurs simultaneously with the telophase stage of mitosis, resulting in the formation of two genetically identical daughter cells.

Therefore, interphase is the phase in which DNA replicates, mitosis is the phase in which the nucleus divides, and cytokinesis is the phase in which the cytoplasm divides to form two genetically identical daughter cells.

Viruses are particles that Select one: a. contain DNA or RNA which can be injected into a cell. b. have an exterior coat composed of protein. c. can contain an enzyme which catalyzes the reaction to make DNA from the viral RNA. d. All of these answer choices are correct.

Answers

Answer:

d. All of these answer choices are correct.

Explanation:

Viruses have an exterior coat composed of protein, the capsid. Inside of it, there is DNA or RNA. When the virus has RNA, it has an enzyme that allows the synthesis of DNA from RNA. This type of virus is a retrovirus since it does the inverse process, from RNA, it gives DNA and not the other way round.

First, as the capsid has proteins, it attaches to a receptor in the cell's membrane. Then the DNA or ARN enters the cell taking it as a host since it uses the cell's structure to replicate the viral DNA and make viral proteins and DNA that then it assembles to form new viruses that will be released to infect other cells.

The process that Mildred used is known as _______

Radiocarbon dating

Faulting

Indexing

Superposition

Explanation:

Radiocarbon dating is a process of determining the age estimates of various objects and materials using the radioactive properties of an isotope of carbon, carbon-14.

Radiocarbon dating uses the ratio of two isotopes of carbon, carbon-12 and carbon-14 present in materials which contains carbon to determine their age.

There is a fairly constant ratio of carbon-12 and carbon-14 in living organisms. However, at death, due to the decay of carbon-14 to carbon-12, the ratio begins to change. Since the rate of decay of carbon-14 is fairly constant, a property known as half-life, the time it has taken for carbon-14 to decay to carbon-12 can be calculated. This calculated time will givee the age of the fossilised material.

The diagram represents the Moon and its orbit around Earth. The arrow labeled X represents the force that keeps the Moon in its orbit. Which force is represented by X?

Answers

Answer:

A. Gravity

Explanation:

The strong gravity, or "Pull" of the Earth is what keeps the moon in orbit.

I hope this helps!

Gravity is the force represented by X that keeps the Moon in its orbit. Therefore, option (A) is correct.

What is gravity?

Gravity is a force that attracts two objects with mass towards each other. It is the force that gives weight to physical objects and is responsible for the friction between objects and the surface of the Earth.

The strength of the gravitational force between two objects depends on their mass and the distance between them. The greater the mass of the objects, the stronger the gravitational force between them. The farther apart the objects are, the weaker the gravitational force between them.

The most familiar example of gravity is the force that attracts objects towards the surface of the Earth. The Earth has a large mass, so it has a strong gravitational pull. This is why objects on the surface of the Earth are "weighted" and feel heavy.

If the mrna is damaged, it directly interferes with the ability of a animal cell to do which of the following?

Answers

Answer:

Proteins.

Explanation:

If the mRNA is damaged, it directly interferes with the ability of producing proteins in animal cell because mRNA is responsible for carrying the protein blueprint from a cell's DNA to its ribosomes which are considered as the machines of the cell that produces proteins for the cell. These messenger RNA has the information about what type of proteins are required to produced for the cell. So if mRNA is damaged, the ribosomes are unable to produce proteins for the cell.

Why are leaves necessary for a plant?​

Answers

Answer:

PLEASE MARK AS BRAINLIEST!!

Explanation:

Leaves provide food and air to help a plant stay healthy and grow. Through photosynthesis, leaves turn light energy into food. Through pores, or stomata, leaves “breathe” in carbon dioxide and “breathe” out oxygen.

Leaves are the primary way plants interact with the atmosphere and take care of their basic needs. a plant can only survive for a few days without leaves. If the plants doesn't have any leaves than the plants wouldn't exist in the earth because leaves prepare food for the plants through the process of photosynthesis. and provides air to help a plant grow. leaves help the plants breath, and also helps in releasing water vapor through pores called stomata.

Evaporation- Is the the process in which water changes from a liquid to a gas or vapor.

Condensation- Is the process in which water vapor or gas in the air is changed into a liquid. Is the opposite of evaporation.

Precipitation- Precipitation is water from clouds in the form of rain, freezing rain, sleet, snow, or hail.

Collection- This is when water that falls from the clouds as rain, snow, hail or sleet, collects in the oceans, rivers, lakes, streams. Also some will soak into the ground and will collect as ground water.
