Answer:

The enzyme Topoisomerase functions to prevent super-coiling of the  DNA molecule during replication.

Explanation:

  • During replication, topoisomerases are required to relieve the positive supercoiling that arises from DNA unwiding mediated by Helicases.
  • A DNA topoisomerase is a nuclease that breaks a phosphodiester bond in a DNA strand.
  • All topoiomereases are classified as  Topoisomerase I and Topoisomerase II  depending on whether they cleave one or two strands respectively.
  • Topoisomerase I do not use ATP as a source of energy, the reaction is powered by energy stored in super-coiled DNA.
  • Topoisomerase II also do not require external energy but it utilizes ATP hydrolysis to drive conformation changes in the protein during reaction cycle.

How do nutrients get to the cells in a flatworms solid acoelomate body?
wariber [46]
The nutrients get to the cells in a flatworms solid acoelomate body by diffusion process. Flatworms feed primarily on protozoa and bacteria, smaller worms and tiny organisms, dead or alive, that they come across. Based on the species of the flatworms , they also consume plant materials. They rely on diffusion to transport oxygen and nutrients to their internal tissues.

Involuntary is which type cardiac, smooth, or skeletal?
grin007 [14]

Answer:

Smooth and cardiac

Explanation:

Smooth and cardiac muscles are both involuntary.

This means we do not consciously control them. Smooth muscles are found, for example, in the esophagus, and small intestine. The cardiac muscles are found in the heart.

The skeletal muscles are those that we control consciously, such as the muscles for moving our arms and legs.
