Answer:
Steps of photosynthesis:
Step 1: Energy is captured from sunlight.
Step 2: Light energy is converted to chemical energy,
which is temporarily stored in ATP and the energy
carrier molecule NADPH.
Step 3: The chemical energy stored in ATP and NADPH
powers the formation of organic compounds, using carbon
dioxide (CO2 ).

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.
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.

What is cell?
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.

Which organelle plays an important role during mitosis, helping to move chromosomes around the cell
a
Oь
Ос
Od
vacuoles
Golgi bodies
chloroplasts
centrioles
Answer:
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.

What is one way that Earth's ocean currents help regulate global climate?
A.
by creating an uneven distribution of the Sun's energy across Earth's surface
B.
by moving warm water and precipitation from the Equator toward the poles
C.
by carrying cold water and floating ice from the Equator toward the poles
D.
by transmitting sunlight from the ocean surface to the ocean floor
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.
What are Earth's ocean currents?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.

Which best describes the first step in genetic engineering? A. Fragments of DNA that have desired genes are isolated to form recombinant DNA for use in a host. B. All the DNA from a desired organism is isolated to form recombinant DNA for use in a host. C. Different sections of DNA from a desired organism are inserted into a host so that beneficial traits will be expressed. D. One strand of DNA is isolated and inserted into a host so recombinant DNA can be formed.
Answer:
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.

How is it possible that the reactants and products for both chemical equations have the same quantity of carbon, hydrogen, and oxygen atoms, yet the reactants and products are different molecules?
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.
