Answer:
Ocean surface winds play a vital role in the water cycle as the tropical Pacific Ocean and overlying atmosphere react with, and influence each other. Easterly surface winds along the equator control the quantity and temperature of the water that upwells (moves or flows upward) to the surface.
Incomplete dominance is when both of the the alleles represented are heterozygous thus creating a third phenotype known as a blend e.g white and red flowers gives a pink one. Whereas dominant recessive both alleles are homozygous and thus the phenotype depicts that gene.
Phospholipid bilateral is a thin polar membrane made of two layers of lipid molecules. These membranes are flat sheets that form a continuous barrier around all cells.
Producers convert energy from the environment into carbon bonds such as sugar glucose
The correct answer is: A. How does changing the amount of water affect the growth of corn?
While options B, C & D are not impossible to test, option A is the only question that can be tested using quantitative methods, such as statistical analysis. The question in option A states: "How does changing the amount of water affect the growth of corn?". This question is easily testable using scientific investigation, because controlled or measured amounts of water can be added to corn, and the consequent growth rate of corn can be easily measured and recorded. However, the questions in options B, C & D cannot be precisely measured using quantitative tools, since they aim to measure qualitative (subjective) factors, such as: ethics, happiness and disappointment.
