Explanation:
The photophosphorylation process which results in the movement of the electrons in a cyclic manner for synthesizing ATP molecules is called cyclic photophosphorylation. ... During cyclic photophosphorylation, the electrons are transferred back to P700 instead of moving into the NADP from the electron acceptor.

Answer:
Yes, it accelerates
Explanation:
We have that:
The ball was stationary implies that its initial velocity, u = 0
It gained 5m/s means that its final velocity, v = 5m/s
Using first law of newton, we can determine whether it accelerates or not.
Substitute values for v and u
Make a the subject
<em>This implies that the ball accelerates over a period of time t</em>
<em></em>
Another way to tell if it accelerates or not is to consider the change in velocity.
When there is an increment in velocity of an object, the object accelerates.
In this case, the velocity increases from 0 to 5. Hence, we can conclude that it accelerates
Answer:
B. Three
Explanation:
Messenger RNA : mRNA : Encodes amino acid sequence of a polypeptide.
Transfer RNA: tRNA : Brings amino acids to ribosomes during translation.
Ribosomal RNA: rRNA : With ribosomal proteins, makes up the ribosomes, the organelles that translate the mRNA.
Answer:
Parenchyma cells are the abundant cells that make up ground tissues in plants.They are flat at point of contact.they have thin primary cell walls and have large vacuoles for storage of food.In leaves they are called mesophyll and are sites of photosynthesis.In other parts they are sites for respiration and protein synthesis.
Sclerenchyma cells are cells with rigid secondary cell walls.Their cell walls are hardened with lignin which is the main chemical component of wood.Mature sclerenchyma cells cannot elongate and most of them are dead.
Explanation:
The ozone layer reduces the amount of UV radiation reaching earth. Excessive UV radiation can increase global temperatures.
