No, the cell membrane regulates movement of materials into and out of cells.
There are so many examples for that in different areas, like Perylene experiment carried out in our lab recently.Here's one link: http://www.alfa-chemistry.com/perylene-cas-198-55-0-item-282870.htm
At the inner mitochondrial membrane<span>, a high energy electron is passed along an electron transport chain. The energy released pumps hydrogen out of the matrix space. The gradient created by this drives hydrogen back through the </span>membrane<span>, through ATP synthase.</span>
Answer: Define Active transport
Explanation: The moving of molecules or ions across the cell membrane.
Hope this helps!
The answer is C.
The man’s genotype must be AB. The woman’s genotype can be either BB or BO as both correspond to a blood type (which is a phenotype) of B.
Each parent passes on one allele. The man can contribute A or B and the woman can contribute B or O.
The possible genotype combinations are therefore AB, AO, BB, and BO. These correspond to the phenotypes AB, A, B, and B.
