What is it called when molecules move from low to high concentration across plasma membranes?

Biology

Answer: Osmosis

Explanation: Osmosis is a process in which water move from an area of low solute concentration to an area of high solute concentration through a selectively permeable membrane. For osmosis to occur, it must be through a selectively permeable membrane. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.

Ostrovityanka [42]

Responding to the environment is the characteristic of life that best describes the process of homeostasis. Homeostasis is the ability of a body or living organism to adjust its internalenvironment in order to maintain astable equilibrium regardless of the external changing conditions.

Cross bridge formation between myosin heads and actin molecules is caused by the elevation of calcium ion concentration in the c
Naily [24]

Answer:

by the sarcoplasmic reticulum's calcium ion pumps

Explanation:

Rigor mortis or postmortem rigidity, is a state caused by chemical changes in the muscles that occur post mortem and  cause the limbs of the corpse to stiffen.

This occurs because after death, there is no cellular respiration and consequently, no oxygen nor ATP (ATP is required for the muscle relaxation).

Calcium enters the cytosol after death because it is released due to the deterioration of the sarcoplasmic reticulum and due to the breakdown of the sarcolemma. Ca2+ ions activate the formation of actin-myosin cross-bridging necessary for the contraction. Muscles are unable to relax, because myosin heads continue to bind with the active sites of actin and there is no ATP to destabilize the myosin-actin bond.

4.6 Fusion of the reading frames of the bcr and abl genes, as is often observed in cases of chronic myelogenous leukemia (CML),
kirill115 [55]

Answer:

The answer is reciprocal chromosomal translocation

Explanation:

The Philadelphia chromosome (Ph) is the truncated chromosome 22 generated by the reciprocal translocation t(9;22)(q34;q11) and was first identified in 1960 in a patient with CML [3]. Translocation of the proto-oncogene tyrosine-protein kinase (ABL1) gene located on chromosome 9 to the breakpoint cluster region (BCR) gene located on chromosome 22 results in a BCR-ABL1 fusion gene on the Ph [4, 5]. Three BCR-ABL1 fusion gene hybrids encode BCR-ABL1 protein isoforms p210, p190, and p230, which have persistently enhanced tyrosine kinase (TK) activity. These aberrantly activated kinases disturb downstream signaling pathways, causing enhanced proliferation, differentiation arrest, and resistance to cell death [6, 7]. Tyrosine kinase inhibitors (TKIs) targeting the BCR-ABL1 protein are the most successful targeted therapy for Ph-positive leukemia.
