Answer:
2nd one
Explanation:
Regardless of latitude or time of year, the sun's angle reaches closest to 90 degrees (perpendicular lines are 90 degrees) -- and is therefore at its most intense -- at the midpoint of the day: noon.
<span>The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipidsand proteins. A phospholipid is a lipid made of glycerol, two fatty acid tails, and aphosphate-linked head group.

The answer is logistic growth.
It is modeled by an S-shaped curve. Carrying capacity (K) is the maximum individuals of a population that a habitat can sustain indefinitely
given the limited resources in the environment. Before this number
is achieved, the population grows exponentially and slows as it gets close. When
the K number is reached, the stationary phase enters.
Answer: cellular membrane: The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.
Explanation:
passive transport Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes. Instead of using cellular energy, like active transport, passive transport relies on the second law of thermodynamics to drive the movement of substances across cell membranes.
Considering the choices;
A. blood glucose level and pH
B. amount of light and temperature
C. amount of light and pressure
D.
temperature and pH
Answer;
D.
temperature and pH
The two factors affect an enzyme's operation the most is the temperature and pH.
Explanation;
Enzymes work best at optimum pH and temperature.
At low temperature for example the enzymes are inactivated while at high temperatures enzymes are denatured.
At optimal temperature and pH; the chemical reaction rate is optimal.
