Correct answer: D). Algal cells have a cell wall made of chitin, while plant cell walls are made of cellulose.
Algae and plants are similar as both of them produce their own food by the process of photosynthesis. The main difference is found in their complexity.
The cell wall of the plants is made of cellulose, hemicellulose and pectin, and polysaccharides, while the cell wall of algae is made up of chitin, which is a polysaccharide derived from glucose.

During the course of an action potential, the membrane potential rapidly rises and reaches a peak of about 40 mV before falling
elena-14-01-66 [18.8K]

Answer:

This is because the voltage gated sodium channels which opens for the influx of sodium ions, which caused  increased postivity of the axoplasm closed, with simultaneous opening  of potassium channels.

Therefore depolarization stopped, thus  propagation  and transmission of action potential (caused by depolarization) which cause the reversal of charges in the membrane (making the axoplasm  more negative) for the voltage rise to 40mV also stopped.

In addition the  simultaneous opening  of voltage gated potassium channels caused K+ to leave the axoplasm to the external environments. This makes the inner membrane to be negative further lowering the potential, to -75mv. This is  re-polarization.

In the natural carbon cycle, the ocean influences climate by controlling CO2 levels primarily through ________________ and _____
yulyashka [42]

<u>Answer:</u>

In the natural carbon cycle, the ocean influences climate by controlling CO2 levels primarily through <u>biological activity</u> and <u>massive geological events</u>.

<u>Explanation:</u>

Carbon flows in an interchange across each reservoir called the carbon cycle, which has gradual and rapid components. Any cycle shift which moves carbon from one reservoir places more carbon in another reservoirs.Changes that bring carbon dioxide into the environment contribute to higher Earth temperatures.

The carbon cycle appears to keep the balance over the long term that prohibits all Earth's carbon from atmospheric entry or being deposited entirely in rocks. That equilibrium helps to keep the temperature on Earth fairly stable, just like a thermostat.
