The small cell extensions that beat to create an up-ward current are called microvilli.
<h3>What are microvilli?</h3>
Microvilli are small extensions which are found on the surface of the alveoli of the lungs.
The microvilli play an important role in the lungs as the help to remove particles and mucus that may obstruct the lungs as a result of the upward current they create in the lungs from their beating motion.
Therefore, the paralyzed small cell extensions that beat to create an up-ward current are called microvilli.

Answer:
The protein is a symport protein.
Explanation:
Transport proteins are proteins which are involved in the transport of solutes across the cell membrane. The binding of the solute to be transported across the membrane causes a conformational change in the shape of the protein, thereby moving the molecule to the side of nthe membrane it is to be transported. The difference in the concentration of the solute across the membrane known as concentration gradient is mainly responsible for the transport of molecules by the transport proteins.
There are three types of transport proteins: uniport, symport and antiport transport proteins.
Uniporters are involved in moving only one molecule across a membrane
Symporters are involved in moving two or more molecule across a membrane in the same direction.
Antiporters are involved in moving two or more molecule across a membrane in opposite directions.
From the description of the transport protein in the question, both solutes A and B are moved across the membrane simultaneously in the same direction. Therefore, the protein is a symport protein.
Answer:
The most appropriate answer would be The cell will not make functional proteins from that mRNA strand.
The amino acid sequence of the proteins is derived from the nucleotide sequence of the mRNA (messenger ribonucleotide).
If the sequence of mRNA is miscopied, it will change the sequence of amino acids of the protein.
Consequently, the protein may become non-functional.
The answer is fundamental niche
