Answer:
DNA: TTAAGCCCCAAA
RNA: UUAAGCCCCAAA
Explanation:
A binds with T (Apples on Trees)
C binds with G (Cows eat Grass)
So complementary sequence would be TTAAGCCCCAAA
For RNA sequence:
For RNA:
A binds with U
T binds with A
C binds with G
So RNA complementary will be UUAAGCCCCAAA

Answer:
The oceans are present on the 70 percent of the world but only 5 percent of the total oceans are explored yet.
There are many reasons of this problem but the most important is the hydrostatic pressure.
Hydrostatic pressure can be described as the pressure or weight exerted by the water on the object.
With every increase in 10 meters the pressure increase by 6.47kg (14.27lbs) each square inch of surface.
Due to extreme pressure, oxygen level in the cells of body fluctuates and person becomes unstable and can become unconscious.
