Answer:
A. 3/16
Explanation:
The four possible outcomes for Stem length are:
Tt, tT, TT and tt.
The dominant trait (tall stems) will manifest itself in 3 out of 4 outcomes, so its ratio is 3/4.
The four possible outcomes for flower coloration are:
Rr, rR, RR and rr.
The non-dominant trait (white flowers) will manifest itself in 1 out of 4 outcomes, so its ratio is 1/4.
Multiplying both ratios gives us the ratio of offspring that have tall stems and white flowers:

Therefore, the answer is A. 3/16

Answer:
A. Duodenum
Explanation:
Duodenum is the first part of the small intestine which receives bile juice, pancreatic and intestinal digestive juices. The digestive enzymes present in these juices completes the process of digestion.
The lining of the duodenum has numerous finger-like projections called intestinal villi. The villi are specialized to absorb the digested food by providing increased surface area for the process of digestion. Hence, among the given options, the absorption of digested food occurs in duodenum.
But the many-celled algae, make their food by photosynthesis. Plants have complex, multi-cellular reproductive systems and might need wind, birds, or bugs for pollination. Algae can reproduce through tiny spores or even by replication or the growth of broken piec
