Answer:
The backbone of the helix attached to the sugar, in between the Deoxyribose sugar
Explanation:
Two strands of DNA form a twisted ladder-like structure by wrapping around one another. The deoxyribose and phosphate units that make up the backbone of each strand alternate in direction. Adenine (A), cytosine (C), guanine (G), and thymine (G) are the four bases that are joined to each sugar (T).
18% because C pairs with G. A pairs with T. T and C are not complementary base pairs, but we do know that if a molecule consists of 32% T, it must have 32% A as well.
32 + 32 = 64
100 - 64 = 36
36 ÷ 2 = 18
There must be 18% of C.
<span>When plants moved on the land they had to adapt to new environment and </span>to deal with new <span>problems. The main problem for plants was to figure out how to regulate water loss within the cells. One of the solution was the formation of the waxy covering on top of leaves-cuticle, which evolved on the surface of leaves to reduce water loss. Another problem for plants was to figure out how to obtain resources from soil and air, so they developed vascular tissue to transport water/sugar within the plant.</span>
Hi there,
Speed of sound in water is approximately 1500 meters per second (the exact speed depends on the depth of water and its density) and the speed of sound in air is approximately 340 meters per second. So sound is almost 4.4 times faster in water than in air. I hope this helped :)
