Answer:
Mitochondria within the electronic transport chain, are responsible for producing the energy that the cell needs, adjusting its operation to meet the metabolic needs of the body.The mitochondrion is the place where oxygen is consumed from aerobic organisms through various electron carriers and proton translocators (H +).
Explanation:
The lipid matrix of the membrane provides an impermeable barrier to ion translocation, as well as a topological organization to the catalysts in the membrane matrix that allows them to transport both e- and ions within and across the membrane in vector form. The transformation of oxidative energy into other forms of energy is carried out, initially, by generating a transmembrane electrochemical potential difference of H + ions (protomotive force). This force is the product of the asymmetric distribution of H + on both sides of the membrane, as those are translocated through it by the enzymatic complexes of the respiratory chain.The protomotive force is made up of two closely related components: one, function of the difference in chemical concentration of hydrogens across the membrane (a pH gradient) and another, dependent on the difference in electrical charge of H + ions on both sides of it (an electrical potential gradient). Gradients of electrical charge and chemical potential produce a field in which a force is exerted that tends to attract previously expelled protons into the mitochondria. It is the enzymatic complex of ATPase, the means by which the thermodynamically reversible translocation of H + ions is catalyzed. At the same time, the chemical activity of the H + on both sides of the membrane causes a change in the equilibrium constant of the enzyme, inducing it to catalyze the synthesis of ATP.

movement of the asthenosphere
the Earth's rotation and centrifugal forces
Answer:
Movement of the Asthenosphere
Explanation:
The Asthenosphere is the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur. This convention causes warmer magma in the earth's core to rise and cooler to fall and be heated again. The circular motion caused by this convection is what is thought to cause the Earth's crust to move.

The body temperatures of ectotherms, like lizards and turtles, can fluctuate with the environment. How do ectotherms maintain homeostasis?
Endotherms, such as birds and mammals, use metabolic heat to maintain a stable internal temperature, often one different from the environment. Ectotherms, like lizards and snakes, do not use metabolic heat to maintain their body temperature but take on the temperature of the environment.

The leaves of plants have many specialized structures. Which statement explains the importance of the stomata and guard cells for the plant?
o They protect the plant from pests
o They are involved in plant reproduction
They work together to regulate water loss and gas exchange.
o They regulate the amount of water that enters the plant for cellular respiration
Answer:
They work together to regulate water loss and gas exchange.
They work together to regulate the loss of water and exchange of gases.
Stomata and guard cellsThe tiny pores or openings in plant tissue, which allow for the exchange of gases are known as stomata.
The unique cells, which surround stomata and work to close and open the stomatal pores are known as guard cells.
Both these helps a plant to take in carbon dioxide at the time of photosynthesis and also assist in reducing the loss of water by getting closed when conditions are dry and hot.
Thus, stomata and guard cells work together to regulate the loss of water and gas exchange.

At the end of the mitotic cell cycle, a cell divides into two cells. What must happen before the cell divides? A. The number of organelles doubles. B. Chromosomes must be copied. C. Four nuclei must be formed. D. The membrane thickens.
Answer: The correct option is B.
B. Chromosomes must be copied
Explanation:
This is because, before mitosis occurs the cells must first duplicate or replicate it's DNA during interphase and this is because mitosis is a type of cell division where a parent cell divide into two daughter cells which are genetically identical to the parent cell and carry the exact number of chromosomes of the parent cell.
Answer:b
Explanation:
Movement of chromosome segment to a non-homologous chromosome. This type of chromosomal mutation occurs when one chromosome swaps genetic information with a different chromosome (this is NOT Crossing Over). O Inversion O Duplication O Deletion O Translocation
Answer:
The correct answer is ''Translocation.''
Explanation:
Translocation is a chromosomal abnormality that is due to a change in position of a chromosomal segment to another non-homologous chromosome of the same nucleus or to another part of it. It is produced by the exchange of segments between two chromosomes without loss of genetic material is called reciprocal or balanced translocation, when it gives rise to monocentric chromosomes.Translocations can be detected cytologically because the structural heterozygote forms a quadrivalent (4-chromosome association) in meiotic prophase. Sometimes they can also be detected by changes in the size of the chromosomes if the exchanged segments are of different lengths.

What does the Greek Root "pro" mean?
Answer:
The prefix pro- primarily means “forward” but can also mean “for.” Some words that the prefix pro- gave rise to are promise, pro, and promote. When you, for instance, make progress, you are stepping “forward,” whereas if you give the pros in an argument, you are speaking “for” something by stating its advantages.

Do mutations in body cells contribute to genetic variation?(1 point)
A) No, the causes of body cell mutations are outside the body and cannot alter DNA.
B) Yes, the mutations can be passed on to offspring and contribute to variation in the population.
C) Yes, these body cell mutations lead to mutations in the gametes.
D) No, the mutations cannot be passed to offspring and only affect the individual.
A mutation is the alteration of the genetic sequence of an organism, which can either be inherited or cannot be inherited. The mutation when transmitted to the offspring leads to genetic variation.
The correct answer is:
Option B. Yes, the mutations can be passed on to offspring and contribute to variation in the population.
Mutation is the change in the genetic sequence of the organism, which can be caused due to environmental factors and can be inherited.
The mutations can lead to genetic disorders, chromosomal disorders, or any other conditions. The mutations like a disease or adaptation that can be passed onto the offspring can result in genetic variation.
The mutation leads to genetic diversity, as the mutation is also the first step towards evolution. The organisms better suited to the environment will survive more and adapt more. These changes in the organisms will be inherited by the offspring leading to genetic variation.
Therefore Option B is correct.
