Answer:   This is what I could find on it.

There are many external factors that can disrupt homeostasis. Disease, toxins, and pathogens are just a few examples.

Some diseases can have external causes, like a toxin or pathogen invading the body. Toxins are products of plants, animals, fungi, or bacteria that hurt cells in some way.

Answer:

Yes, this may be a little confusing when taking a first glance at the chemical equation.

Explanation:

You see, the whole process of balancing an equation is to make sure the reactants and products have the same amount of mass/atoms.

With that being said, the products to appear to be different after going through the chemical change. this is because of what was happening through that process. But, all of these atoms are still within the final product.

For example, if you take water in a container, one with a lid and one without a lid, then you heat up both containers of water, the container that has the lid open will seem like the water is gone, that the atoms are not the same. Actually, if we take a look at the closed container, all of that gas that was formed from the water still has the same amount of atoms contained in it. As for the open lid container, the atoms are all there, but some of them was just released into the air outside of the jar, making it seem like there is less.

The study of chemicals is called chemistry.

It is possible to have different chemical properties but the same number of elements present in the reactant and the product.

According to the law of mass of conservation of the mass. it states that the number of elements present in the reactant and the product will always remain the same.

Hence, according to this law, the mass and the quantity of the element are the same but the bonds and the arrangement of the elements are different which causes different chemical behavior.

Hence, it is possible.

By moving warm water and precipitation from the equator to the poles and cold water from the poles back to the tropics, ocean currents function much like a conveyor belt, hence option B is correct.

Global climate is regulated by ocean currents, which also assist to balance out the unequal distribution of solar energy hitting Earth's surface.

Sunlight energy is absorbed and stored by the ocean, which controls the temperature of the Earth's atmosphere. More than half of the solar energy that reaches Earth's surface is absorbed by the ocean, which both absorbs and releases heat more slowly than land.

By moving warm water and precipitation from the equator to the poles and cold water Global climate is regulated by currents, which assist balance out the unequal distribution of solar energy that reaches the surface of the Earth.

Therefore, by moving warm water and precipitation from the equator to the poles and cold water from the poles back to the tropics, hence option B is correct.

Explanation:

Duplicated centrioles are responsible for moving chromosomes during mitosis.

They are involved in the formation and organization of spindle during cell division (mitotic phase) and also in the process of cytokinesis.

It is composed of nine triplets of microtubules that are the proteins of cytoskeleton.

Spindle fibres contain multiple proteins that help in the binding with centromere during cell cycle.

They originate from the poles of the cell by the organelle called centriole, and attached to the kinetochore of the chromatid.

Many spindle fibres are just connected between two poles, as they are not attached to the chromatids.

These fibres orient the chromosomes into pairs, to the metaphase plate into a line during metaphase.

During anaphase they are shortened, which pulls the chromosomes to the opposite poles separated from the pairs.

At the end in telophase, where nuclear membrane becomes visible it disappears.

In this way the spindle fibers help in the separation of chromosomes into two new daughter cells. This process is also known as the distribution of heredity or genetic information between new cells.

Answer:

d. It consists of alternating phosphates groups and deoxyribose molecules

Explanation:

The statement above best describes a portion of the molecule that is represented here.

Actually, the molecule represented here is the Deoxyribonucleic acid (DNA). The molecule is composed of two polynucleotide. The DNA carries genetic properties that lead to growth, development, reproduction and functioning of organisms. The phosphate group and deoxyribose molecule are found attached to the DNA. The phosphate group is also found in RNA and in ATP. The deoxyribose is known to be a five-carbon sugar molecule which helps to form the phosphate backbone of DNA molecules.

The given molecule is consists of alternating deoxyribose molecules and phosphates groups.

DNA:

It is the biomolecule that is made up of nucleotide polymers. Nucleotide are made up deoxiribose sugar, phosphate, and nitrogenous bases.

In a DNA strand one nucleotide link with another by the phosphodiester bond in which 3' OH of pentose sugar bond with 5' OH of phosphate.

Therefore, the given molecule is consists of alternating deoxyribose molecules and phosphates groups.
