Answer:
C
Explanation:
RNA is found mostly in the nucleus but can also be found in the cytoplasm, but it is not limited to it.
1. Hypotonic solution; a solution that has lower salt concentration than the solvent concentration inside the cells.A hypotonic solution has more solvent than the solute, therefore, when a cell is placed in a hypotonic solution it gains water through osmosis and increases in size. However, for an animal cell, it will increase in size and then bursts because it lacks cell wall.
2. Isotonic solution is the solution with the same slat concentration as the solvent concentration. In a isotonic solution, the solute concentration and the solvent concentration are at equilibrium, hence if a cell is placed in a such a solution there will be not net change or effect on the cell.
3. Osmosis is the diffusion of water across a semipermeable membrane. Osmosis involves the movement of water molecules from a region of high concentration to a region of lower concentration through a semipermeable membrane. An example of osmosis is the intake of water molecules in the plants through the roots.
4. Phagocytosis is the process where cells eat other cells or large substances. Phagocytosis involves the mechanism by which cells or phagocytes binds to a cell or an item it wants to engulf on the cell surface. For example; when a macrophage ingests a pathogen, the pathogen becomes trapped in a phagosome which then fuses with a lysososme and destroys the pathogen by digesting.
5. A phospholipid is a molecules with a polar and a non polar ends, that along with protein makes up the plasma membrane. Phospholipid is a class of lipids that consists of two hydrophobic fatty acid tails and a hydrophilic head consisting of a phosphate group. It is the main component of the cell membrane, and makes the membrane to have a selective permeability.
6. Pinocytosis is the process where cells eat small or dissolved substances. Pinocytosis is also known as fluid endocytosis; it is a type of endocytosis where small particles that are suspended in an extracellular fluid are brought into the cell by the means of invagination of the cell membrane, which cause the particles to be suspended in a vesicle.
7. A polar molecule is a molecule that has a partial positive and negative charges at each end. Polar molecules results from the polar bonds which comes from the difference in electronegativity between the atoms involved. Water is a good example of polar molecule because it has a partial positive charge on one side (hydrogen) and a partial negative charge on the other (oxygen).
8. A protein is a large complex organic molecules consisting of a large number of amino acids linked together by peptide bonds. They are usually long chains of amino acids or polypeptides, that are essentially molecules used in metabolic processes. They have a range of functions, which includes, repair and maintenance, source of energy, structural components, chemical messengers, among others.
The medulla is the inner region of the parenchyma of the kidney. The medulla consists of multiple pyramidal tissue masses, called renal pyramids.
The kidney's parenchyma's interior section is called the medulla.
The renal pyramids, which are triangle-shaped structures with a dense network of nephrons within them, are a collection of several pyramidal tissue masses that make up the medulla.
The Bowman's capsule, which is shaped like a cup and is located in the cortex of the kidney, is at one end of each nephron. The glomerulus, a group of capillaries that conducts blood from the renal arteries into the nephron where plasma is filtered via the capsule, is encircled by it.
The filtered fluid exits the capsule and travels via the collecting ducts and distal convoluted tubule before exiting the body through the ureter. It then travels down the proximal convoluted tubule to the loop of Henle. The complicated management of water and ion concentrations in the body is made possible by the numerous components of the nephrons, each of which is selectively permeable to distinct molecules.

Similar to the conversion of pyruvate to acetyl-CoA, each pyruvate molecule loses a carbon atom with the release of carbon dioxide. During the decomposition of pyruvate, electrons move to NAD + to produce NADH. It is used by cells to produce ATP.
- NADH: Three molecules are produced in the Kleb circuit
- FADH2: One molecule is produced in the Kleb circuit
- ATP or GTP: From each molecule of pyruvate during the conversion of succinyl-CoA to succinic acid Two molecules of ATP are produced. The presence of the enzyme succinyl-CoA synthetase.
