Answer:
As the diagram is not given, hence let's generally describe the movement of molecules along the cell membrane.
Molecules can either pass through the cell without using energy through the process of passive transport. An example includes molecules of oxygen.
Molecules which are large and un-polar cannot move through the cell membrane easily. These molecules will require energy to move through the cell membrane. These molecules might move in with the help of the carrier or facilitated proteins. Examples include molecules of glucose.
Presumably whatever their nutrition and health requires, for instance, if a tree frog requires fruit flies to maintain a healthy and balanced diet, then the conservation center probably feeds their tree frogs fruit flies.
A. multiply the chance that it will be a boy x the chance he will have PKU (1/2 x 1/4)
<span>B. chance of having PKU + chance of albinism </span>
<span>C. chance PKU x chance albinism</span>
Answer:
<h2>Helicase, topoisomerase ii /gyrase, single strand binding proteins.</h2>
Explanation:
DNA replication is the process in which DNA is replicated with the help of various enzymes and proteins..
Helicase is the enzyme which unwind the DNA strands, After unwinding, topoisomerase removes these twists. Single strand binding proteins stabilize the single strands of DNA during replication.
