Answer:
Light is sn important element in the growth of a plant.
Explanation:
Light is an important factor influencing plant growth. It is a common observation that plants grow towards light. Charles Darwin and his son Francis Darwin first observed that the coleoptiles of canary grass responded to unilateral illumination by growing towards the light source (phototropism). After a series of experiments, it was concluded that the tip of coleoptile was the site of transmittable influence that caused the bending of the entire coleoptile due to more growth on the dark side. That transmittable influence is now thought to be the phytohormone called auxin.

Answer:the following can be done to allow more NaCl to dissolve;
1.) heating the mixture.
2.) Addition of extra water to the solution.
Explanation:
When sodium chloride is dissolved in water, the polar water molecules are able to work their way in between the individual ions in the lattice. The water molecules surround the negative chloride ions and positive sodium ions and pull them away into the solution. This process is called dissociation. Now when the solution is heated, the rate of the dissociation between the two molecules increases leading to more dissolution of NaCl. Also in the absence of heating, more Water molecules can be added to the solution to decrease it's saturation thereby favouring the dissolution of more NaCl.

In my opinion ...it is option A:)
Often referred to as the molecule of life, DNA (deoxyribonucleic acid) is found in almost all living things. It acts as a type of chemical code that contains instructions, known as genes, for how the body and all its different parts grow, develop, function, and maintain themselves.
