Answer:
C. The high concentration of hydrogen ions in the intermembrane
Explanation:
Merry Christmas
The two statements that describe the process of ATP synthesis in the electron transport chain are: "ATP synthase spins when the hydrogen ions rush past, and high concentrations of hydrogen ions in the intermembrane space allow them to diffuse." These are options A and C.
What is the significance of the hydrogen in the electron transport chain?In this electron transport chain process of cellular respiration, electrons are passed from molecule to molecule through a series of protein complexes in the inner membrane of the mitochondria, where ATP synthase is an enzyme located in the inner membrane that makes ADP into ATP.
Hence, the two statements that describe the process of ATP synthesis in the electron transport chain are: "ATP synthase spins when the hydrogen ions rush past, and high concentrations of hydrogen ions in the intermembrane space allow them to diffuse." These are options A and C.

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.

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

Cells store waste in ________.
Answer:
Vacuoles
Explanation:
Cells store waste in organelles called "lysosomes." Thus, the complete statement is "Cells store waste in lysosomes"
Where do cells restore waste?Lysosomes are membrane-bound organelles found in cells. They contain digestive enzymes that can break down various types of biological molecules, including waste materials.
Lysosomes play a crucial role in cellular waste management and recycling processes.
They are responsible for breaking down and recycling cellular waste, unwanted materials, damaged organelles, and foreign substances that enter the cell. By storing waste and containing the digestive enzymes, lysosomes help maintain cellular cleanliness and proper functioning.

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.

Which of the following would represent the strand of DNA from which the mRNA
strand "CUCAAGUGCUUC" was made?
*
The option that would represent the strand of DNA from which the mRNA strand "CUCAAGUGCUUC" was made is "GAGTTCACGAAG."
What is DNA?DNA stands for Deoxyribonucleic acid. It may be defined as a type of molecule that is present inside cells that contains the genetic information responsible for the development and function of an organism.
It allows information to be passed from one generation to the next. Transcription is the process of copying a segment of DNA into RNA, especially in the form of mRNA.
It is the first step of protein synthesis through which complementary mRNA strands would be formed from DNA sequences. In this process, the adenine is replaced by thymine and vice-versa while guanine is replaced by cytosine and vice-versa.
Therefore, the option that would represent the strand of DNA from which the mRNA strand "CUCAAGUGCUUC" was made is "GAGTTCACGAAG."

Answer:
6. Find the Nazca plate and the South American plate. How are they different? Are they moving toward or away from each other?
Answer:
7. How is the Nazca plate moving in relation to the Pacific plate?
Answer:
8. How are convection currents in the mantle (geosphere) and in the oceans (hydrosphere) similar? How are they different?
Answer:
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.
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.

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.
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.

the way that genetic information is coded in DNA is-
Answer:
with bases
Explanation:
Genetic information is coded in DNA by means of four bases: two purines (adenine and guanine) and two pyrimidines (thymine and cystosine). Each adjacent sequence of three bases (a codon) determines the insertion of a specific amino acid. In RNA, uracil replaces thymine.
