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
When the condition is acidic the substance that would leached is d.aluminum which is then the most ample element in the earth. Aluminum becomes a big part of one's life. It can be use in one's daily life like a beer can, cables,etc.

(B) Doing research how plastic affect the environment is the activity that would be within the field of Biology.
Biology is the study of life. Environment includes the surroundings and the lives involved on it. Therefore, plastic affect both the surrounding and the lives of every living creature.
Answer:
The lipoproteins with the highest proportion of triglyceride are CHYLOMICRONS.
Explanation:
Lipoproteins are biochemical molecules that are made up of lipid and protein; their primary function is to transport fat molecules in blood and in extracellular fluids. There are different types of lipoproteins, one good example of these are plasma lipoprotein particles, which are made up of HDL (high density lipoprotein), LDL (low density lipoprotein), VLDL (very low density lipoprotein), IDL (intermediate density lipoprotein) and ULDL (ultradensity low lipoproteins).
ULDL are also known as chylomicrons and they have the highest quantity of triglycerides.
