Answer:
Adhesion and surface tension
Explanation:
Capillary action is the tendency of a liquid to rise or fall in a narrow tube. Two main terms are required to explain capillary action; adhesion and cohesion.
Cohesion is the force of attraction between molecules of the same kind while adhesion is the force of attraction between molecules of different kinds.
Forces of adhesion causes water to move up in a capillary tube. The water is held as it rises by surface tension forces acting on the circumference of the meniscus. The water keeps rising in the tube until the weight of the water drawn up in the tube balances the surface tension acting at the top column of the water.
Answer: a) substrate and cofactors b) covalent modification
Explanation:
Metabolic pathways involve all the chemical processes takes place in the enviornment or in an organisms.The metabolic pathways are controlled through the catalytic activities of enzymes.
The availability of enzyme is regulated by substrate and cofactors present in enzyme and enzyme activity is commonly regulated via covalent modification.
Enzymes are highly selective in nature and bind to a specific substarte only. The active site in enzyme binds with the substrate to form enzyme substrate complex. Coactors assist the enzyme activity, without cofactor enzyme can not perform its activity.
Hence enzyme availibility is regulated by substrate and cofactors regulates.
Covalent modifications regulates activity of enzyme as it involves addition and removal of chemical group to synthesis required protein. It can change the chemical properties of the site by targeting one or multiple amino acid.
Thus the correct answer is a) substrate and cofactors b) covalent modification
Answer:
the answer would be chromosomes.
Explanation:
A chromosome contains hundreds to thousands of genes.
