Answer:
carbon dioxide at normal atmospheric concentrations is limiting for the metabo- lism and growth of most land plants of the world. These plants share a comparable photosynthetic metabolic pathway, termed C3 photosynthesis. With an increase in CO2 there is an increase in photosynthesis and growth.
Explanation:
<h2>Answer:</h2>
Chromosomes are structures present in the nucleus of the every organism's cell and it is the DNA packed with histones proteins.
Explanation:
DNA deoxyribo nucleic acid is the nucleotide sequence which is the blue print of the structural and functional characteristics of the whole organism.
Nucleus of the call is very small to be contain the DNA of cell. So DNA is present in the condense form by wrapping around the histones proteins which is known as cell division.
At the time of cell division, it is present in chromosomal form to equally divide the genetic material.
I’d talk about how enzymes have that induced fit model. A substrate is unique to that specific enzyme. The substrate binds to the enzymes active site (or sometimes allosteric site) which in turn alters the conformation or shape of that particular enzyme
