Answer : Corpus Callosum
Explanation : By the end of the preschool period, the brain structure called the <u>Corpus Callosum </u> becomes considerably thicker, with individual fibers that helps to co-ordinate brain functioning between the two hemispheres.
Corpus Callosum by definition is a thick band of nerve fibers that divides the cerebral cortex lobes into left and right hemispheres in the brain, which connects the left and right sides of the brain allowing for communication between both hemispheres.
Answer: Glycine has the smallest aspect chain of any amino acid. Its measurement is regularly fundamental in allowing polypeptide chains to make tight turns or to strategy one some other closely.

A prediction is making a forecast of what will happen in the future based on past experience or evidence
Answer:
Constitutive activation is the alteration of a protein or signaling pathway such that it is functional or engaged even in the absence of an upstream activating event. For example, RasD is constitutively active because it cannot bind GAP and therefore remains in the GTP-bound, active state even when cells are not stimulated by growth factor to activate a receptor tyrosine kinase.
Constitutively active Ras is cancer promoting because cells will proliferate in the absence of growth factors, and thus normal regulatory mechanisms for cell proliferation are bypassed.
(a) A mutation that resulted in Smad3 binding Smad4, entering the nucleus, and activating transcription independent of phosphorylation by the TGFβ receptor would render Smad3 constitutively active.
(b) A mutation that made MAPK active as a kinase and able to enter the nucleus without being phosphorylated by MEK would render MAPK constitutively active.
(c) A mutation that prevented NF-KB from binding to IK-B or that allowed NF-KB to enter the nucleus and regulate transcription even when bound to IK-B would render NF-KB constitutively active.
