Explanation: Electron transport chain
How are hydrogen ions pumped across the membrane?
Image result for what is used to make the mitochondrial membrane and is where hydrogen ions are pumped through to create ATP
During electron transport, energy is used to pump hydrogen ions across the mitochondrial inner membrane, from the matrix into the intermembrane space. A chemiosmotic gradient causes hydrogen ions to flow back across the mitochondrial membrane into the matrix, through ATP synthase, producing ATP.

brain or nervous system cells are called as neurons
Cells in the nervous system which have various functions related to support and nourishment are called glial cells.
What are the functions of glial cells?Glia, also called glial cells (gliocytes) or neuroglia, are non-neuronal cells in the central nervous system (brain and spinal cord) and the peripheral nervous system that do not produce electrical impulses.
Functions include: clean up brain "debris"; transport nutrients to neurons; hold neurons in place; digest parts of dead neurons; regulate content of extracellular space; promote synaptic connections.
Any of the cells that hold nerve cells in place and help them work the way they should. The types of glial cells include oligodendrocytes, astrocytes, microglia, and ependymal cells.

the number of phenotypes in a population is determined by
Answer:
The number of phenotypes produced for a given trait depends on how many genes control the trait.
Explanation:
Based on heredity, the number of phenotypes in a population is determined by the number of alleles for that triat as well as the nature of the alleles.
What is a phenotype?A phenotype is a physical expression of a gene.
The phenotype of an organism is influenced by the inherited alleles for that gene that an organism has.
Alleles are alternate forms of a gene.
Alleles may either be;
dominant,recessive, incompletely dominant or co-dominant.The phenotype of that organism will thus depend on the nature of the alleles of that gene or trait.
Therefore, the number of phenotypes in a population is determined by the number of alleles for that triat as well as the nature of the alleles.

Why are common cold viruses difficult to cure?(1 point)
A copy of the DNA is made from the viral RNA.
The virus leads to other viral infections such as the flu and HIV.
The viral genome mutates very quickly.
Vaccines prevent the development of a cure.
Answer:
You are very correct the answer is c
Correct option is ''The viral genome mutates very quickly.''
Viruses can't reproduce on their own as bacteria do, instead, they attach themselves to healthy cells and reprogram those cells to make new viruses. It is because of all of these differences that antibiotics don't work on viruses. Antibiotics and medications treat bacterial infections. These antibiotics cannot treat or cure a common cold as colds aren't caused by bacteria.
Common cold viruses are difficult to cure as the viral genome mutates very quickly.

B. a likelihood based on the chance that a particular event will or will not occur during an experiment
C. a testable explanation or answer to a scientific question based on prior knowledge or research
D. a statement of fact that is accepted as true because it has always been observed to be true through observations and experimentation
Answer:
I know I am too late to help you, but I couldn't find an answer when looking for this question. I got it right and it is A. an explanation of phenomena that can be accepted as true because it is supported by repeated observations and experimentation.
Explanation:
Evolution by way of natural selection is most likely an explanation of phenomena that can be accepted as true because it is supported by repeated observations and experimentation. The correct option is A.
What is natural selection?Natural selection is the process through which organisms that are more adapted to their environment tend to survive and reproduce more than those that are not. Tree frogs, for example, are occasionally eaten by snakes and birds.
Evolution is a process in which living things or other evolve or change over time. Natural selection is also a reason for evolution, which takes a large amount of time.
Therefore, the correct option is A. an explanation of phenomena that can be accepted as true because it is supported by repeated observations and experimentation

Explain how a father with brown eyes and a mother with blue eyes can have children
with either brown or blue eyes. Remember to use complete sentences and correct
grammar.
Answer:
Brown eyes are a dominant trait.
Explanation:
Brown eyes are a dominant trait, and blue eyes are a recessive trait. If the father has brown eyes, they can have either a BB or Bb genotype; the mother must have a bb genotype in order for her eyes to be blue.
Refer to the Punnett Square below to see how it's possible for this mother and father to produce children with both colored eyes.

Answer:
Hey, your answer should be D
Explanation:
Good luck friends
The researcher who theorized that hypnosis comes about as a form of roleplay between hypnotist and subject is Milton Erickson, who is in Option D. Milton Erickson was a famous American psychiatrist and psychotherapist.
What is Milton Erickson?He is widely known for his pioneering work in the field of hypnosis. He believed that hypnosis is a form of communication between the hypnotist and the subject and that it involves a process of "roleplay" in which both parties take on certain roles or identities. In this sense, the hypnotist takes on the role of a facilitator or guide, helping the subject access their own inner resources and abilities. The subject, on the other hand, takes on the role of an active participant in the hypnotic process, using their own imagination and creativity to bring about positive changes in their thoughts, feelings, and behaviors.
Hence, the researcher who theorized that hypnosis comes about as a form of roleplay between hypnotist and subject is Milton Erickson, who is in Option D.

A scientist performs a series of mutation screens to look for mutations that reduce ATP production. One of the mutants, compared to a wild-type cell, has reduced levels of ATP and NADH and increased levels of FAD and pyruvate. Which hypothesis best fits these observations?
The hypothesis that best fits the observation that one of the mutants has reduced levels of ATP and NADH and increased levels of FAD and pyruvate is that the mutation is disrupting the citric acid cycle (Option 3).
What is the citric acid cycle?The citric acid cycle, also known as the Krebs cycle, is the second step of cellular respiration which is required to generate ATP through the oxidation of pyruvate.
The reduced form of Nicotinamide adenine dinucleotide (NADH) produced during the citric acid cycle is then used in oxidative phosphorylation (the third step of cellular respiration) in order to generate more ATP.
Therefore, with this data, we can see that the citric acid cycle generates the reduced form of Nicotinamide adenine dinucleotide (NADH) and thus increases the production of ATP, thereby a mutation in an enzyme that works in this pathway may also hamper the proportion of ATP.
Complete question:
