24. After eating a cookie, facilitated diffusion allows sugar molecules to enter the cell. Which component of the cell membrane participates in this process?
A. Phospholipid bilayer
B. Carbohydrate chains
Facilitated Diffusion
C. Protein channels
Outside of cell
D. Fatty acid tails
mann
W
W
Inside of cell

Explanation:

A cell membrane is composed of two phospholipid layers in which each molecule contains a single phosphate head and two lipid, or fatty acid, tails. The heads align along the inner and outer boundaries of the cell membrane, while the tails occupy the space in between. Only small, nonpolar molecules can pass through the membrane through simple diffusion. The lipid tails reject polar, or partially charged, molecules, which include many water-soluble substances such as glucose. However, the cell membrane is peppered with transmembrane proteins that provide passage to molecules that the tails would otherwise block.

d. in sexual reproduction, offspring have more chromosomes than

either parent.

asexual reproduction results in offspring which are genetically the same as the parent organism (not counting a rare mutation). sexual reproduction produces a random mixture of the genetics derived from both parents
