Is when you breathe in oxygen and exhale carbon dioxide
Answer:
Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix.
Explanation:
Integrins are transmembrane protein receptors that attach the cell cytoskeleton to the extracellular matrix (ECM) in animal cells. These glycoproteins (integrins) are highly dynamic heterodimeric molecules that anchor cells in their position and transduce signals into and out of cells. Integrin-ligand binding activates signaling pathways that are involved in fundamental cellular functions including, among others, organization of the cell cytoskeleton, cell migration, regulation of the cell cycle, etc.
The heart and the arteries of a person, both contracts to pump the blood throughout the body. The aorta, which is the largest artery of the human body, pumps the blood from the heart to the entire body of a person. The oxygen-rich blood is pumped out of the left ventricle when its contraction into the aorta, from where it is transported to the whole body.
Hence, the given statement is true.
Answer: supersaturated
Explanation: A supersaturated solution is a solution in which the dissolved solute is more than the solvent can hold at that particular temperature.
A solution is a substance which sontains a dissolved solute. A solution can be saturated, unsaturated or supersaturated.
A saturated solution contains the maximum amount of dissolved solute a solvent can hold at that temperature.
An unsaturated solution contains less amount of solute than the solvent can hold at that temperature, this means that more solute can still dissolve in the solution.
A supersaturated solution contains more solute that can be dissolved in the solvent at that temperature.
