A cell membrane that transports glucose, ions, or other charged or polar molecules is likely to have a higher percentage and gre

ater variety of proteins than one that does not transport these molecules.

Answer: True

Explanation:

<u>A cell membrane consists of a lipid bilayer made of polar phosphate head and a nonpolar lipid tail.</u> It is semipermeable and regulates the transport of materials through it. For this,<u> it is selectively permeable</u> and since it is made of lipids, hydrophobic and small polar molecules can diffuse easily through it by simple diffusion and down their concentration gradient. However, polar molecules, large molecules (such as glucose) and ions are not able to pass through it because they are repelled.

To accomplish the transport of these molecules that can not diffuse, proteins embebbed in the membrane function as carriers that enable the transport of polar molecules, large molecules and ions by passive (through facilitated diffusion, down its concentration gradient) or active transport (movement against its concentration gradient).

Why does the United States experience winter during the months of November through early March
Ghella [55]

The United States are entirely located in the Northern Hemisphere. It is bordering Canada on the north, and the air masses that form over it have big influence on the climate of the United States. Most of the United States falls under the influence of the air masses coming from the north, with only the southern parts of the east and west coastlines not being heavily affected. The air masses that form over Canada are cold continental air masses. They move towards south, thus toward the United States in November, quickly pushing the warmer air masses, and replacing them, bringing in cold weather conditions, which last until March.

Rus_ich [418]

Answer:

Anabolic.

Explanation:

The metabolic reactions of the body are important to maintain the physiology and homeostasis of the body. Two main types of reaction in the body are catabolic reactions and anabolic reactions.

The anabolic reaction is the reactions that are involved in the formation of the large molecules from the simpler substances. The anabolic reactions are involved in the growth and repair process as complex protein and factors are required that can only be obtained by the anabolic reactions.

Thus, the correct answer is option (3).
