Answer:
B) Helicase uses energy from ATP Hydrolysis
Explanation:
Helicase's primary function is to separate the annealed nucleic acid strands. It is a motor protein and moves directionally along the phosphodiester backbone. It usually separates strands of double helix DNA or self annealed RNA. It used the energy from ATP hydrolysis and breaks hydrogen bonds between nucleotide bases.
In human body 95 types of helicases are found. They have sequence motifs required for ATP binding, ATP hydrolysis and translocation along nucleic acid phosphodiester backbone. The variable portion in their amino acid sequence imparts specific feature to each helicase.
The correct answer is B) An electron beam passes over the specimen's surface and displaces electrons, which are then focused on a screen to form an image.
A channel protein serves as a tunnel across the membrane into the cell. More specifically, channel proteins help molecules across the membrane via passive transport, a process called facilitated diffusion. These channel proteins are responsible for bringing in ions and other small molecules into the cell

The right option is; The neuromuscular system
The neuromuscular system directs and coordinates the interrelated activities of the gastrointestinal tract.
The neuromuscular system connects the central nervous system to the peripheral nervous system and it is composed of the nervous system, somatic system, autonomic system and the muscular system which include skeletal, cardiac, and smooth muscles. The neuromuscular system is important in the activities of the gastrointestinal tract, body movements and breathing.
