Cell membranes are mostly made up of lipids (fats)
Answer:
Because most cells, including erythrocytes, are exposed to glucose concentrations outside the cell that are greater than those within, facilitated diffusion leads in net glucose inward movement.
ATP stands for Adenosine TriphosPhate. It is a molecule, responsible for <span>many essential roles in the </span>cell - energy transfer from and into the cell.
<span>If we have two cells A and B and Cell A have less circles in the cell, while cell B has more circles outside the cell, then: </span><span>
ATP is being used to move the molecules out of the cell by cell A , only. </span>
Answer:
The correct answer is conservative model.
Explanation:
There are 3 hypothesized DNA replication models: semi-conservative, conservative and dispersive model (see figure). Heavy isotope of nitrogen makes diference when density gradient centrifugation experiment conducted and two diffent bands contaning different isotopes of nitrogen are observed. With one band only containing 14N means bacteria only copies one strand in one replication which supports semi conservative model.

The slower wave through the body of rock is called the secondary or S wave.
