Compared to arteries, valves have no pulse, have thin walls and have valves that prevent backflow of the blood. The pressure in the veins is less than that of the arteries, hence, there is no pulse. They are nearer to the surface of the skin. It also connects arteries and capillaries which transport blood all throughout the circulatory system.
Answer:
The correct answer is The bridge between cystein which connects parts of a protein is stable but non covalent interaction.
Explanation:
Disulfide bond link the sulfhydryl group of two adjacent cystein residues in a protein structure.
Dulsulfine bond is stable but is not a non covalent interaction.Disulfide bond itself is a covalent interaction.
Answer:
osmolarity depends upon molarity.
glucose is a non-ionizing substance. it won't break down and will go as a whole.
osmolarity means the solute concentration of a solution.
here, the solvent is water.
therefore, 1 osmole = 1 mol
the ions of glucose after forming a solution (i) = 1
osmolarity = 1.5 M glucose × 1
= 1.5 osmoles of glucose.
Answer:
The correct answer is D) integral membrane proteins.
Explanation:
257/5000
Ionic channels consist of oligomeric transmembrane integral proteins (formed by the assembly of several subunits). Said proteins act as gate channels that allow the passage of certain ions eg. calcium, sodium, potassium, etc.
