D. Number of protons in an atom's nucleus
Answer:
Due to their hole size.
Explanation:
Some molecules can pass directly through the phospholipid bilayer because of their small size which can easily pass through the small holes of phospholipid bilayer, while those that are too large or too charged need to pass through a membrane protein because membrane protein has a large holes through which large molecules can easily pass through the semi-permeable membrane of the cell by active or passive transport.
at sea level in arterial blood it is between 35 mmHg and 45 mmHg. at sea level in venous blood it is between 40 mmHg and 50 mmHg
I hope this is right and helps:)
The geologic time scale is a system of chronological dating that relates geological strata to time, and is used by geologists, paleontologist, and other Earth scientists to describe the timing and relationships of events that have occurred during Earth's history. Hope I helped!
Answer:
True
Explanation:
Hydrophobicity is the aversion to the water of a molecule (or part of it). Amino acids with a hydrophobic R group (glycine, alanine, valine, leucine, isoleucine, proline, phenylalanine, methionine, and tryptophan) <em>will fold with the R groups in the interior to avoid water. This behavior is one of the most important forces in protein folding. </em>You can see it exemplified in the image I added.
I hope you fidn this information useful and interesting! Good luck!
