Explanation:

Animals do not possess any sort of cell wall since animals always move, they are not static in one particular place, therefore they need to be flexible.Animal cells lack the thick cell wall that plant cells have, so there is no need for a central vacuole to exert pressure on the surrounding cell

Answer:

Brainliest pls

Explanation:

Animal cells have a larger amount of vacuoles than plant cells, but they are much smaller. Animal cells lack the thick cell wall that plant cells have, so there is no need for a central vacuole to exert pressure on the surrounding cell

How many years would it take the Atlantic Ocean to grow 500 centimeters? Show your work.
dlinn [17]

Answer:

250 years

Explanation:

The Atlantic Ocean is not static, but instead it is very active, and it is actually spreading from its central part. In its central part, this ocean has a mid-ocean ridge. This basically means that there is constant formation of new crust from the magma that comes out, and the old crust is pushed sideways as the new one is formed. On an annual level, the mid-ocean ridge is spreading out by an estimated 0.02 meters, thus that is how much the Atlantic Ocean is spreading out each year. In order to get to the result as to how many years are needed for the Atlantic Ocean to spread 500 cm, we just need to multiply the annual spreading with the number of cm in question:

0.02 x 500 =250

Thus we get a result of 250, meaning that in 250 years the Atlantic Ocean will spread out 500 cm in total.

densk [106]

Answer:

The cytochrome b6f is a large multi-subunit protein, which accepts electrons from the plastohydroquinone.

One electron moves linearly toward plastocyanin while the other goes through a cyclic process, which effectively pumps more protons into the thylakoid lumen.

Explanation:

The cytochrome b6f is distributed among both grana and stroma thylakoids equally. They are usually large and embedded in the membrane.
