The answer is B Microscope :)
Answer:
Root hair cells are alive and therefore need energy, which is why root hair cells contain many mitochondria in them. Root hair cells don't contain chloroplasts. Chloroplasts are used by the plant to make food using light energy. Since the roots aren't exposed to any form of light, they have no need for chloroplasts.
Both photosynthesis and respiration involve the conversion of energy from one form to another through a series of biochemical reactions. Both processes use and produce ATP in reactions that are carried out on membranes and are controlled by enzymes.
The answer would be A: 1:16
This is because the letters mean:
Y: yellow
y: green
S: round
s: wrinkled
Thus, because the lowercase letters represent recessive alleles, both letters must be lowercase in order for the gene to show in the offspring.
So, if you wanted green, wrinkled, seeds, the only option (in letter form) would represented by:
ssyy
Therefore, because there is only one block with those letters, and sixteen blocks total, the ratio is 1:16.
