A nursing infant is able to obtain disease-fighting antibodies, which are large protein molecules, from its mother’s milk. These molecules probably enter the cells lining the baby’s digestive tract via:.
a. osmosis
b. passive transport
c. exocytosis
d. endocytosis

D

Explanation:

A is not possible because osmosis is a term given only for the movement of water down it's potential through a partially permeable membrane.

B is not possible since the molecule is big and since it's an antibody, it's polar. It being polar makes it impossible to passively cross the phospholipid bilayer of the cell membrane.

C is not possible because it describes the action of something bulky leaving the cells, not entering them.

Endocytosis is the uptake of large molecules into the cells by forming phagocytic or pinocytic vesicles.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
