In the context of joint mobilization techniques, for what are inferior femoral glides at 90 degrees of hip flexion used?
Hip Inferior Glide is used to improve hip flexion. The technique is performed in supine with the hip flexed to 90°.
This technique can be used for decreasing muscle spasm or pain, and is also useful to increase accessory joint movement for flexion and abduction movements.
By performing the therapy the clinician’s hands can be clasped at the superior proximal femur or a mobilization strap can be used to enhance grip and reduce sliding on subject's skin. The clinician can simply lean back to impart an inferior force to the femur with a counterforce of the shoulder on the distal femur.

Cytotoxins induce:___.
a. the creation of peptide fragments
b. perforations in the cell membrane
c. cell division
d. apoptosis
Cytotoxins induce perforations in the cell membrane and apoptosis. So the correct option is (b) and (d).
By releasing two different types of preformed cytotoxic proteins—the pore-forming protein perforin, which creates holes in the target cell's membrane so the granzymes can enter, and the granzymes, which appear to be able to induce apoptosis in any type of target cell—cytotoxic CD8 T cells kill their target cells.
Particularly, the production of TNF-alpha and IFN-gamma by cytotoxic T cells promotes macrophage activation. Infected cells are attacked and eliminated by macrophages, which also stop uncontrolled cell proliferation like tumours.
Therefore, Cytotoxins induce perforations in the cell membrane and apoptosis. So the correct option is (b) and (d).

What is the final electron acceptor of the series of re-dox reactions that are facilitated by the electron transport chain in mitochondria?
In electron transport chain (ETC) , Complex IV, also known as cytochrome c oxidase, oxidises cytochrome c and delivers the electrons to oxygen, the final electron carrier in mitochondria.
The electrons in the electron transport chain (ETC) pass through a chain of proteins that raises its reduction potential and results in an energy release. A proton gradient is produced by pumping hydrogen ions (H+) from the mitochondrial matrix to the intermembrane space, with the majority of this energy being lost as heat in mitochondria .
This gradient generates an electrical difference with a positive charge outside and a negative charge inside, increasing the acidity.

Glycolysis requires an initial energy investment, which allows for the production of relatively larger quantities of atp during?
Glycolysis requires an initial energy investment, which allows for the production of relatively larger quantities of ATP during Substrate-level phosphorylation
The process of glycolysis starts with a single glucose molecule, which has a six-carbon ring structure, and finishes with two molecules of pyruvate, a three-carbon sugar. Two separate phases of glycolysis exist. Energy is utilized to alter the first step of the glycolysis process so that the six-carbon sugar molecule can divide equally into two three-carbon pyruvate molecules. ATP and nicotinamide-adenine dinucleotide (NADH) are created during the second phase of glycolysis.Substrate-level phosphorylation is the direct transfer of a high-energy phosphate group from a phosphorylated intermediate metabolic molecule in an exergonic catabolic pathway, which results in the generation of ATP from ADP.learn more about glycolysis here:

The characteristic that can distinguish bacterial cells from cells in the other domains of life is that only bacterial cells have peptidoglycan cell wells.
What is the major difference between a bacterial cell and the cells of other organisms?
Animal and plant cells are different from bacterial cells in a number of ways. One key distinction is that, unlike plant and animal cells, bacterial cells lack internal organelles including mitochondria, chloroplasts, and a nucleus.
Bacteria can be categorised according to their morphology, such as bacilli (rod-shaped), cocci (sphere-shaped), and spirilli (spirals). In that they have cytoplasm, ribosomes, and a plasma membrane, bacteria resemble eukaryotic cells.

The reduction of blood volume occurs following severe dehydration and hemorrhage; however, although dehydration results in an increase in hematocrit, immediately following hemorrhage hematocrit is unchanged. Explain this difference.
During bleeding, both formed elements (platelets, white blood cells, red blood cells) and plasma are lost from the circulatory system. They are lost proportionally, so initially there is no change in hematocrit.
Hematocrit is the percentage of the blood volume made up of elements (Hct = cell volume/blood volume). During dehydration, only water and electrolytes are lost, and the number of cells remains constant - the same number of cells in a smaller volume leads to an increase in hematocrit. When the body tries to restore blood volume, the first thing to recirculate is water from the ECF and this increases the amount of water without increasing the amount of red blood cells, so the compensatory mechanism causes the hematocrit to fall.
