The correct answer is D i.e. krebs cycle occurs in mitochondria.
what is mitochondria?
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP)
what is krebs cycle?
The tricarboxylic acid (TCA) cycle, also known as the Krebs or citric acid cycle, is the main source of energy for cells and an important part of aerobic respiration. The cycle harnesses the available chemical energy of acetyl coenzyme A (acetyl CoA) into the reducing power of nicotinamide adenine dinucleotide (NADH).
it is a closed cycle which produce 8 intermediates which are;-

Please Help! What molecules need to travel through ATP synthase to help it create ATP?
Answer:
The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.
Explanation:
That's the answer but not all of it just pick out the actual answer.
The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed.
What is RNA polymerase?RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus. The enzymes prevent many genetic mutations from being expressed.
Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it and primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.
Therefore, The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed.

All organisms utilize adenosine triphosphate (ATP) as their major source of energy. The molecules
of ATP and ADP (adenosine diphosphate) + P: (inorganic phosphate) form a cycle to allow for a
constant source of energy-rich ATP molecules.
Which of the following MOST accurately describes the role of ATP as a source of energy?
O ATP absorbs energy as it is converted into ADP + Pi.
ADP + P; release energy as they are converted into ATP.
O When ATP is converted into ADP + Pi , energy is released and used by the cell.
O When ADP + Pi are converted into ATP, energy is released and used by the cell.
Answer:
When ATP is converted into ADP + P energy is released and used by the cell.
Explanation: ATP contains energy, when a certain part breaks off it converts into ADP and releases energy for the cell tp use.
When ATP is converted into ADP + Pi , energy is released and used by the cell is the most accurately describes the role of ATP as a source of energy.
What is ATP?An organic substance called adenosine triphosphate (ATP) gives energy to a variety of biological functions in living cells, including muscular contraction, nerve impulse transmission, condensate dissolving, and chemical synthesis.
ATP is frequently referred to as the "molecular unit of currency" of intracellular energy transfer and is present in all known forms of life. It either transforms into adenosine monophosphate (AMP) or adenosine diphosphate (ADP) when absorbed in metabolic activities (AMP).
ATP is replenished by other processes. Every day, the human body recycles the equivalent amount of ATP to its own body weight. Additionally, it serves as a coenzyme and a precursor to DNA and RNA.
Therefore, When ATP is converted into ADP + Pi , energy is released and used by the cell is the most accurately describes the role of ATP as a source of energy.

Which surface erosion event does the most short- term damage?
Loss of topsoil from farmland.
Movement of rocks by glaciers.
Occurrence of mud slides after heavy rains.
Pollution of water sources caused by runoff.
Answer:
Occurrence of mud slides after heavy rains.
Explanation:
Soil erosion is defined as the removal of top soil from the land and it affects the fertility of the soil. It is also known as soil degradation.
Soil erosion has both short-term and long-term damage. Short-term damage of erosion includes the occurrence of mudslides after heavy rains which is called landslide. It is a short-term damage because landslides took long-duration to happen and when happened it can be shortly recovered using machines.
Hence, the correct answer is "the Occurrence of mudslides after heavy rains."
Use hydrogen bonding to explain how the unique properties of water you observed emerge.
Due to the existence of hydrogen bonding between the hydrogen atom and an oxygen atom of a water molecule, it shows the following unique properties.
It is polar in nature.It has a high heat of vaporization and high specific heat.Its solid form is less dense as compared to its liquid form.It illustrates other properties like cohesion and adhesion.It acts as a universal solvent.How the charges are distributed in a water molecule?The distribution of charge is determined by the fact that the oxygen atom attracts electrons a bit more strongly than the hydrogen atom. This is due to the unequal sharing of electrons between the two different atoms.
This unequal sharing of electrons is responsible for obtaining a slight negative charge near the oxygen atom, while a slight positive charge near the hydrogen atom.
Therefore, it is well described above.

Which do scientists link to increased hurricane strength?
O A. Higher ocean temperatures in the arctic
B. Higher land temperatures in the arctic
C. Higher ocean temperatures in the tropics
O D. Higher land temperatures in the tropics
Answer:
Higher ocean temperatures in the tropics
Explanation:
apex :)
Higher ocean temperatures in the tropics are linked to increased hurricane strength. Therefore, option (C) is correct.
What is hurricane strength?Hurricane strength is a measure of the intensity of a tropical cyclone, which is a rotating storm system that forms over warm ocean waters in the tropics. The strength of a hurricane is measured using the Saffir-Simpson Hurricane Wind Scale, which ranks hurricanes from Category 1 (weakest) to Category 5 (strongest) based on their sustained wind speeds.
Hurricanes can cause significant damage due to their strong winds, heavy rainfall, storm surges, and flooding. The strength of a hurricane is influenced by a variety of factors, including warm ocean temperatures, low wind shear, and high humidity. As global temperatures continue to rise due to climate change, it is expected that hurricanes will become more frequent and more intense, which could have significant impacts on coastal communities and infrastructure.
