The correct answer is that it directs cellular activity. 
DNA undergoes transcription to produce mRNA, which then translated into proteins. Proteins plays a variety of roles in the cellular activities. For example protein can serve for structural support, they can exist in the form of enzymes that catalyze reactions, and functions as messengers.

In July 1994 the comet
KiRa [710]

Answer:

The correct answer is B) the gravitational attraction that exists between all

bodies.

Explanation:

Every plant has a gravitational force which extends beyond its atmosphere.

The formula for calculating this gravitational pull is given as follows:

                                                       Fg= GMm/r2

F_{g} = Force of Gravity

<em>G </em>= Gravitational Constant

<em>M </em>= Mass of the Planet

<em>m </em>= The Comets Mass

<em>r  </em>= The distance between the centre of the comet and that of the planet

The force of gravity of the Planet can cause the comet to move faster in it's course towards the planet. This is called centripetal acceleration.

Cheer.

1) The process arrow A represents is photosynthesis.

2) Arrow A represents light energy transformation. Light energy from the sun is converted into chemical energy in plants.

3) Photosynthesis is part of a carbon recycling process in the carbon cycle. Plants absorb light energy and convert it to chemical energy. Plants absorb carbon dioxide which is exhaled by humans and animals. Plants then produce oxygen which is absorbed by humans and animals. Animals also eat plants thus passing the carbon compounds along.

I hope this makes sense. Hope this helps! :)
