Answer:
a) Soil type
b) Water quantity and quality
c) Intensity of light
d) Quantity and quality of fertilizer applied.
e) Environmental condition
Explanation:
Fertilizer plays an essential role is providing the essential nutrients to plants thereby boosting their growth.
Hence, in order to conduct a controlled experiment which shall monitor the impact of fertilizer on the growth of plants, all other factors which affect the growth of plants must be standardized or kept constant. These factors include -
a) Soil type
b) Water quantity and quality
c) Intensity of light
d) Quantity and quality of fertilizer applied.
e) Environmental condition
I'm pretty sure the answer is B. Invest in alternative energy sources that do not burn fossil fuels. The reason I would pick B is because in Antarctica the ice is melting more and more over time because, cars and factors etc are burning fuels which result in more damage to the ozone layer.

Answer:
enable capillarity
Explanation:
It is well known that water tends to adhere to the walls of the vessel in which it is contained. This is due to the force of adhesion which is defined as the force of attraction between unlike molecules. Cohesion is defined as the force of attraction between like molecules. In the case of a plant, cohesion of water molecules in the xylem vessels prevents the water column from breaking. The forces of adhesion, surface tension and cohesion are the basis of capillarity,that is, the rise of liquids in capillary tubes.
