Answer:
The matrix is the innermost compartment of a mitochondrion . Here, the
the Krebs cycle occur(s), breaking down pyruvic acid into carbon dioxide in a series of reactions.
Explanation:
The innermost compartment of a mitochondrion is filled with a matrix. It is the site for the Krebs cycle. Here the pyruvic acid is broken down into carbon dioxide.
What is the Krebs cycle?The primary source of energy for cells and an essential component of aerobic respiration is the tricarboxylic acid (TCA) cycle, sometimes referred to as the Krebs or citric acid cycle. The cycle converts the acetyl coenzyme A (acetyl CoA) chemical energy into the reducing force of nicotinamide adenine dinucleotide (NADH).
The TCA cycle is a component of the broader glucose metabolism, which involves the oxidation of glucose to produce pyruvate, which is then further oxidized and reaches the TCA cycle as acetyl-CoA.
The cycle's half of intermediates also serves as the starting point for pathways that lead to significant molecules such as fatty acids, amino acids, or porphyrins. The integrity of the cycle is compromised and the cycle ceases to operate when any of these intermediates are so diverted. Only if the deflected intermediate or a succeeding intermediate that contributes to oxaloacetate can be replaced by anaplerotic (refilling) processes can vital energy production be restarted.
Therefore, the innermost compartment of a mitochondrion is filled with a matrix. It is the site for the Krebs cycle. Here the pyruvic acid is broken down into carbon dioxide.

1. The cells in our bodies are surrounded by these types of solutions.
3. When an animal cell is places in this solution, it will burst (get layer)
4. When an animal cell is placed in this solution, it will shrivel or shrink (get smaller).
5. This is a solution with more solute than the cell.
A) isotonic solution
B) hypertonic solution
C) hypotonic solution
Answer:
1. The cells in our bodies are surrounded by these types of solutions. → Isotonic solution.
3. When an animal cell is places in this solution, it will burst (get layer) → Hypotonic solution.
4. When an animal cell is placed in this solution, it will shrivel or shrink (get smaller) → Hypertonic solution.
5. This is a solution with more solute than the cell. Hypertonic solution.
Explanation:
The cells in the body are in a balance of substances —concentration of solutes— between their cytoplasm and the extracellular space. This balance is dynamic in living beings, due to the constant exchange of ions and substances between the intracellular and extracellular space. For this reason, the extracellular medium is isotonic with the cytoplasm.
A cell can lose or gain water depending on the amount of solutes that a medium has in which it is found, with respect to the cytoplasm. This difference in solutes concentrations produces an osmotic gradient that drags water from the least concentrated solution to the most concentrated, through the process of osmosis, which seeks to achieve an equilibrium of concentrations.
When a animal cell is exposed to a hypertonic solution —with a higher concentration of solutes— it loses water and tends to dehydrate and become smaller.An animal cell in a hypotonic solution receives water, so it can expand and even burst.In practice, the concentrations of intracellular and extracellular solutes depend not only on the osmotic gradient, but also on the concentration gradient of substances.

What are forces and how do they affect the motion of objects?
Explanation:
Force is describe as a push or pull on a body. It causes the motion of a body generally.
Newton's law of motion greatly explains the synergy between force and motion. A body will maintain its position at rest or uniform motion unless if it is acted upon by an external force. When force acts on a body, there is a considerable change in the motion of the body.Which statement best describes the law of conservation of energy?

Explanation:
Bill left a hammer out in the rain all day. The next morning it had rust on it. Oxygen and a metal chemically combine to form rust. What is rust an example of? a. A mixture b. An element c. A solution d. a compound
Answer:
d. a compound
Explanation:
Rust is also known as "iron oxide." It is a compound that is very common around the world. This compound is formed because iron readily combines with the element, oxygen. This is the reason why it is not common to find pure iron in the environment. The process of an iron rusting is called "corrosion."
The speed of rusting largely depends on the electrolytes present. Rain is considered a better electrolyte that speeds up the rusting of the iron than pure water. Thus, this is the reason why Bill's hammer had rusts on it the next morning.

D

kelp forest could help protect the ocean animals from ocean acidification what evidence supports this claim and explain why the evidence supports the claim
Answer:
Kelp is an ecologically and economically important foundation species in California, where forests line nutrient-rich, rocky bottom coasts. One of the detrimental impacts of increased carbon in the atmosphere is its subsequent absorption by the planet’s oceans, which causes acidification – a chemical imbalance that can negatively impact the overall health of marine ecosystems, including animals people depend on for food.
Kelp has been targeted as a potentially ameliorating species in part because of its speedy growth – up to 5 inches per day – during which it undergoes a large amount of photosynthesis that produces oxygen and removes carbon dioxide from the water. In Monterey Bay, the effects of giant kelp are also influenced by seasonal upwelling, when deep, nutrient-rich, highly acidic water from the Pacific is pulled toward the surface of the bay.

William is developing the model shown below to illustrate the process of photosynthesis. He plans to use the model to explain how photosynthesis transforms both energy and matter.
Earth systems include the biosphere, atmosphere, and geosphere. Use the model to explain how photosynthesis acts to transfer carbon between two Earth systems.
Answer:
Biosphere and atmosphere.
Explanation:
Biosphere refers to the living organisms lives on the earth surface. All plants takes carbon in the form of carbondioxide gas from the atmosphere for the production of glucose in the process of photosynthesis and releases carbondioxide by the living organism in the process of respiration as a waste product. We can conclude from this discussion that photosynthesis acts to transfer carbon between two Earth systems such as biosphere and atmosphere.
Why is genetic equilibrium uncommon in actual populations?

How does interphase prepare cells for mitosis
Answer: During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other "normal" cell functions. This phase was formerly called the resting phase.

process of photosynthesis?
Answer:
