Which structure is correctly paired with its function? (1) testis — produces nutrients for the offspring (2) placenta — allows nutrients to diffuse from the mother to the embryo (3) uterus — produces testosterone used in egg production (4) ovary — provides a place for the internal development of the embryo
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.

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.

A scientist is adding thermal energy to a sample of water. Using the Law of Conservation of Energy, what can you predict will happen? (3 points)
The water will increase in temperature beyond the amount of thermal energy that is added, because more energy will be created in this experiment.
The water will decrease in temperature as thermal energy is added, because it cannot create more energy or matter.
The water will not change its temperature because energy cannot be created or destroyed.
The water will increase in temperature in proportion to the amount of thermal energy that is added, but some will be lost to the environment.
Answer:
you can predict that the scientist is using thermal energy and is making the tempature hotter

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

6. Name the two ways electric current can be induced using magnetism.
Answer:
Explanation:
We can induce an electric current inside a coil in 2 ways. This is done due to the relative motion of the coil and the magnetic field.
The first and the easier way to do that would be to induce a current on the coil by moving the coil inside a magnetic field.
The second way would be to induce a current on a coil by altering the magnetic field across it.

Each position of a codon can be occupied by one of four nucleotides. What is the minimum number of nucleotides per codon necessary to specify all 20 of the amino acids that are found in proteins
Answer:
The minimum number of nucleotides per codon necessary to specify all 20 amino acids that are found in proteins is 3
Explanation:
There are four nucleic acids in the RNA, adenine uracil, guanine, cytosine. Each of them combines in groups of three to give the different amino acids. In total, there are 64 different combinations of nucleic acids that codify the 20 amino acids that we need for our vital functions.
From a single fertilized ovum undergoing a series of rapid cell divisions, a human infant develops. The embryonic cells become specialized for a variety of functions. Which of these statements best describes how different cell types develop
Answer:
Each cell has an identical copy of DNA with enzymes controlling the expression of specific genes, leading to a variety of cells
Explanation:
Each cell type contains only the active parts of the DNA needed for that cell type Each cell type has only one chromosome containing the DNA needed for that cell type. Each cell has an identical copy of DNA with enzymes controlling the expression of specific genes, leading to a variety of cells Each cell has multiple copies of DNA that are affected in different ways by the environment to change the function of the cell at regular intervals.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.
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.

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.

Write a paragraph explaining the function of a cell wall and cell membrane and why plants have cell walls and animal cells do not.
plssssssssssssssssssssssss a good paragraph with good vocabulary
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.
