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.

Answer;
-In the smooth ER
In certain kinds of muscle cells, calcium ions are stored in the smooth ER.
Explanation;
-The smooth endoplasmic reticulum is the part of the endoplasmic reticulum (ER) which does not have ribosomes bound to it, thus not exhibiting the bumpy appearance shown by the rough endoplasmic reticulum.
-The smooth ER is important in the synthesis of lipids, such as cholesterol and phospholipids, which form all the membranes of the organism. In addition it is important for the synthesis and secretion of steroid hormones from cholesterol and other lipid precursors.
