Sergio039 [100]

Answer:

e. All could limit protein mobility

Explanation:

Plasma membrane proteins perform a variety of functions: they act preferentially on transport mechanisms, organizing true tunnels that allow substances to pass into and out of the cell, function as membrane receptors, among other functions. These proteins vary greatly in their mobility, some are as mobile as lipids, while others are practically immobile. But FRAP has revealed that some proteins move in cell membranes much more slowly than in reconstituted liposomes. This limited mobility can be explained by the statement in alternative "E" of the above question.

How do the mouth, nose, throat, and lungs fight against<br> pathogens?
irinina [24]

Answer:

Your nose, mouth and eyes are obvious entry points for pathogens. However, tears, mucus and saliva contain an enzyme that breaks down the cell wall of many bacteria. Those that are not killed immediately are trapped in mucus and swallowed. Special cells line and protect the nose, throat and other passages within your body. The inner lining of your gut and lungs also produces mucus to trap invading pathogens.

How does the sequence of bases on one strand of DNA control the sequence of bases on the complementary strand?
nlexa [21]

Answer:

Adenine on one strand can pair only with thymine on the other strand; cytosine, only with guanine.

Explanation:

DNA nucleotides can contain one of four nitrogenous bases. These bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The two strands are held together through hydrogen bonds that form between the nitrogenous bases. Adenine (A) forms bonds with thymine (T) while cytosine (C) forms bonds with guanine (G); A only ever pairs with T, and C only ever pairs with G.

What makes plant material more difficult to digest?
muminat

Answer:

Cell walls can make plant material difficult to digest. Many herbivorous mammals have wide molars. These big teeth help them grind up leaves and grasses. Carnivorous mammals, on the other hand, usually have long, sharp teeth that help them grab prey and rip it apart. A group of herbivores called ruminants have specialized stomachs.
