Answer:

Cephalocaudal

Explanation:

The cephalocaudal principle is known as the general process of physical and motoric development which take place from infancy into toddlerhood and at times at early childhood of which development obeys a head-to-toe progression.

Cephalocaudal is a word that connotes head to toe. Therefore, the cephalocaudal principle is stated as the overall process of development observed in the first set of years in postnatal development majorly with the period from infancy into toddlerhood.

The cephalocaudal principle has to do with both physical and functional development. On the basis of the earliest (i.e., physical development), physical growth in size, weight, and feature differentiation obey this process or form of development. The signs of this is well observed in a contrast of the physical characteristics of an infant In contrast to a toddler. In consideration of the latter, the head is mostly disproportionately big in contrast to the other parts of the body. By the time the preschool years is over for most children, it is well noticed that most must have done away with this top heavy appearance just as seen in our question.

explain how a carrier protein can facilitate the diffusion of glucose or other substances into the cell.

Sveta_85 [38]

Specific chemicals are bound by carrier proteins and transferred on one side of the membrane. The conformational changes they go through next enable the molecule to cross the membrane and exit on the other side.

How carrier protein facilitate the diffusion?

When a molecule diffuses, it usually moves from a high concentration location to a low concentration area until the concentration is the same everywhere in the space.

Contrary to channel proteins, another form of membrane transport protein that is less selective in the molecules it transports, carriers are proteins that move a particular material through intracellular compartments, into the extracellular fluid, or across cells. Carrier proteins are found in lipid bilayer cell structures such cell membranes, mitochondria, and chloroplasts, just like other membrane transport proteins.
