Answer:
Jacob and Monod were intellectually primed to draw the conclusions they did concerning regulation of the lac operon. In part, this was due to their fascination with mechanisms of enzyme regulation. They knew that the activity of some enzymes is regulated when their reaction product binds to the enzyme, changing its shape and therefore its activity. This knowledge allowed them to easily make the intellectual leap to propose B) allosteric regulation of the repressor
Explanation:
When we talk about the mechanisms of enzyme regulation, we refer to allosteric regulation of the repressor. The Allosteric control of transcriptional regulatory proteins allows organisms to react to changes in environmental and metabolic conditions. Also, it is s a thermodynamic phenomenon. When it binds one molecule, the affinity with which a protein binds to a second molecule is altered.
Answer:
As somatic cells are diploid (2n) 2n=56
gametes receive only haploid set so, n=28
Herbivore; carnivore
A rabbit is an example of a herbivore while a hyena is an example of a carnivore.
A herbivore is an animal that obtain its energy by feeding mainly on plants (i.e. that eats no meat). Other examples of herbivores apart from rabbit are cows, sheep and insects. A carnivore is an animal that feeds on meat as the main parts of its diet. Other examples of carnivores apart from hyena are lions, coyotes, tigers and eagles.
