Answer:
The answer is spongy mesophyll.
Explanation:
Between the upper and lower epidermis of a leave, you can find the so called mesophyll tissue which is rich in chloroplasts. There are two types of mesophyll tissue: the palisade and the spongy mesophyll. Whereas the cells of the palisade mesophyll are tightly packed, the cells of the spongy mesophyll are loosely packed.

John is suffering from ariboflavinosis, which is a deficiency disease that is due to inadequate intake of riboflavin and the disease is characterized by sores on the mouth.
Answer:
The correct answer will be option- permits complementary base pairing
Explanation:
DNA contains four types of nitrogenous bases which pair with one another, identified by Erwin Chargaff.
Chargaff suggested that adenine binds thymine forming two hydrogen bonds and cytosine binds guanine forming three hydrogen bonds.
This base pairing between the complementary groups is known as a complementary base pairing which plays an important role in DNA.
The complementary base pairing allows the formation of the helical structure of DNA, the base pairs to be arranged in most energetically and favourable way and replication and transcription processes.
Thus, permits complementary base pairing is the correct answer.
Answer:
Explanation:Twenty fruit flies are placed in each of four glass tubes. The tubes are sealed. Tubes I and II are partially covered with black paper; Tubes III and IV are not covered. The tubes are placed as shown. Then they are exposed to blue light for five minutes. The number of flies in the uncovered part of each tube is shown in the drawing.
These data show that these flies respond to (respond means move to or away from):
