Answer:
flexion
Explanation:
The flexion is a movement of the body part that is described the bending of an elbow, or the clenching a hand into a fist, etc. where the angle between any segment of the body and its proximal segment decreases.
In simple words, the flexion is a movement which decreases the angle between two body parts when they are moved.
The flexion occurs in the sagittal plane.
Thus, the movement of a thumb that would be mostly affected by the lesion of median nerve in cubital fossa is the flexion movement.
The correct answer is option (D) The active transport and the facilitated diffusion both involve the proteins present in the cell membrane.
Facilitated diffusion transport the large and the charged molecules through the protein transport channels present in the cell membrane. In this case, the solute move from a region of higher concentration to lower concentration and it does not require energy.
Active transports takes place when the molecules move from a region of lower concentration to higher concentration via the membrane protein channels.
Both facilitated diffusion and active transport requires the proteins present in the cell membrane.
It doesn't show the choices but, Biostimulation<span> involves the modification of the environment to stimulate existing bacteria capable of bioremediation. </span>
Answer:
The correct answer will be- to synthesise the ATP molecules in respiration process.
Explanation:
The electron transport chain is the last phase of the cellular respiration which helps in the synthesis of a large number of ATP molecules.
The ATP molecules are synthesized when the energy generated by the movement of protons through CF₀ unit takes place.
The movement of electrons in the chain leads to the movement of proton from the mitochondrial matrix to the intermembrane space. This creates the proton gradient across the membrane which to equilibrate the protons move down the concentration gradient through ATP synthase. The energy while this is used to rotate the ATP synthase which coverts the ADP to ATP.
Thus, to synthesise the ATP molecules in the respiration process.
Answer: Daughter cell that does not receive mitochondria, will not be able to produce the energy needed to carry out cell functions. The cell that receives all the mitochondria, will be able to carry out cellular respiration and thus produce energy.
Explanation:
The mitochondrion is a cellular organelle found in eukaryotic cells, and provides the energy needed to carry out cellular activity. They are characterized by their large size, compared to other cell organelles, and their globular shape. <u>Mitochondria generate most of the chemical energy needed to activate the biochemical reactions in the cell</u>,<u> through a process called cellular respiration</u>. It irefers to a set of biochemical reactions by which certain organic compounds are degraded by oxidation into inorganic substances. The chemical energy produced by mitochondria is stored in an energized molecule called adenosine triphosphate (ATP).
Then, if during cell division, one of the daughter cells does not receive mitochondria, it will not have the necessary organelles to carry out cell respiration and will not be able to produce the energy needed to carry out cell functions. The cell that receives all the mitochondria will have no major problems, it will be able to carry out cellular respiration and thus produce energy.
