Answer:

5. when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent

6.They are moving toward each other

7. The Nazca Plate is bounded on the west by the Pacific Plate and to the south by the Antarctic Plate through the East Pacific Rise

8.Convection currents in the mantle drive plate tectonics. Convection is the reason for ocean currents. Ocean currents result from two processes - the action of wind on the surface of the water, and from variation in water temperature that causes movement.

Both the mantle and ocean experience the heat transfer due to bulk movement of molecules within fluids such as gases and liquids, including molten rock; this is called, again, convection.

A. Fragments of DNA that have desired genes are isolated to form recombinant DNA for use in a host.

Explanation:

Genetic engineering, also known as genetic modification, is a technique that involves the manipulation of an organism's genome using biotechnology procedures. The purpose of genetic engineering is to create an organism with desirable traits.

Genetic engineering involves series of steps, however, the very first step is that of DNA EXTRACTION. The fragments of DNA that have desired genes are isolated from the involved organism. The extracted DNA called the recombinant DNA, which is inserted into the host genome.

Answer:

Each cell has an identical copy of DNA with enzymes controlling the expression of specific genes, leading to a variety of cells

Explanation:

The correct answer would be that each cell has an identical copy of DNA with enzymes controlling the expression of specific genes, leading to a variety of cells .

Cell differentiation occurs when a specific segment of the DNA of a cell is expressed during gene regulation and control. The segment of DNA expressed would be dependent on the function the cell is meant to perform. Thus, if cell A is meant to perform an excretory role and cell B is meant to perform a digestive role, even though cells A and B contain the same DNA, different segments of their DNAs would be expressed so that each cell becomes adapted to its role.

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.

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.

Explanation:

A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.[1] Cell walls are present in most prokaryotes (except mollicute bacteria), in algae, fungi and eukaryotes including plants but are absent in animals. A major function is to act as pressure vessels, preventing over-expansion of the cell when water enters.

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.

Answer:

(2) the placenta allows nutrients to diffuse from the mother to the embryo.

Explanation:

The placenta is a shared organ between the mother and the embryo. It diffuses the necessary nutrients from the mother to the future baby and the residues from this one to the mother, so that she can expel them. The placenta separates the mothers and the embryo blood, but it allows the diffusion of said nutrients and wastes through especial parts of the placenta with thin walls.

Answer:C is wrong exocytosis only needs a transport protein and atp

Explanation:

The statement which is not true is it needs a vesicle to move the matter. Thus, option C is correct.

Cell is defined as the base of life as it is the structural as well as functional unit of life. Cell is made up of pre existing cells and the cell contain various cell organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi appratus, nucleus, and cytoplasm.

Basically,cell is of two type one in prokaryotic and another one is eukaryotic. The prokaryotic cell is known as pre mature cells as they do not contain cell organelles and eukaryotic cell are known as advanced and developed cells as they contain several cell organelles.

The unicellular animals are made up of single cell and all the functions carried out in a single cell like amoeba and multicellular organisms are made up of multiple cells and there is specific cell for specific functions.

Therefore,The statement which is not true is it needs a vesicle to move the matter. Thus, option C is correct.
