The statement that describes the ability of the cell membrane to allow various substance to move through is that the cell membrane is preamble and allows only certain substances to pass through.
Explanation:
The plasma membrane is preamble, hydrophobic molecules and small polar molecules diffuse through lipid layer. The integral membrane proteins enable large polar molecules to pass through the membrane.
Some molecules can cross the membrane like hydrocarbons and oxygen. Whereas the large molecules like glucose and sugars cannot cross. The water pass through lipid.
There are no choices, I'll assume that the Nereus in the question refers to the underwater vehicle.
Facts about the Nereus
1) It is an HROV or <span>hybrid unmanned autonomous underwater vehicle. Operated underwater but its operator is in a remote location.
2) Built and operated by WHOI or </span>Woods Hole Oceanographic Institution<span>
3) Designed to explore the deepest surveyed point of the ocean worldwide named Challenger Deep.
4) Deepest dive was at 35,768 feet of the Mariana Trench last May 2009.
5) Was lost on May 10, 2014 after it imploded due to pressure in the Kermadec Trench</span>
Answer:didn’t put the number for how many blue cups were used
Explanation:
Answer;
- 1.2 nM
Explanation;
-Smallest Km means highest affinity, can bind substrate better at lower concentrations. The relationship between rate of reaction and concentration of substrate depends on the affinity of the enzyme for its substrate. This is usually expressed as the Km (Michaelis constant) of the enzyme, an inverse measure of affinity
-Km is therefore, the concentration of substrate which permits the enzyme to achieve half Vmax. An enzyme with a high Km has a low affinity for its substrate, and requires a greater concentration of substrate to achieve Vmax.
