Answer:
DNA helicase separates the two strands of DNA at a replication fork.
Explanation:
To allow DNA replication, two DNA strands should be separated to serve as a template strand. DNA helicases are the enzymes that separate the two parental DNA strands in an energy-dependent way. DNA helicases move along the DNA and separate the two strands by breaking the hydrogen bonds between the complementary base pairs of two DNA strands. The energy released from ATP hydrolysis is used to break the hydrogen bonds.

I had this question a couple days ago
According to the research, the correct option is phospholipids. The majority of the plasma membrane can be described as a bilayer of <u>phospholipids</u> with associated proteins.
<h3>What is the
plasma membrane?</h3>
It is a double layer of phospholipids and proteins, which perform functions of connection, transport and catalysis, which covers and delimits the cells, serving as a border between the inside and the outside of it.
In this sense, one of the peculiarities of phospholipids is that they are amphipathic, their molecules have a part that is soluble in water (that is, hydrophilic) and another that is not (hydrophobic), these lipids are primarily cholesterol, phosphoglycerides and sphingolipids
Therefore, we can conclude that according to the research, the correct option is phospholipids. The majority of the plasma membrane can be described as a bilayer of <u>phospholipids</u> with associated proteins.

Answer: Bacteria are much larger than viruses, and they are too large to be taken up by receptor-mediated endocytosis. Instead, they enter host cells through phagocytosis. Some pathogens, however, have acquired the ability to survive and replicate within macrophages after they have been phagocytosed.
Explanation: This is my answer
<span>The Inner Planets dense and rocky because they are close enough to the sun that the heat has driven off the free hydrogen and helium which forms most of the Gas Giant planets (and most of the universe). Only the heavier elements remain.
And please put the questions in right subject. It belongs to "Physics" not for "Biology".
Hope this helps!</span>
