Answer:
The correct answer would be Late.
Explanation:
Glaciers are the dense layers of solid ice which are accumulated on the tops of the mountains, or on the surface of the mountains, or on the rivers, near the poles, and they are moving slowly under their own mass or weight. Glaciers are most likely to advance during the Late Summers. When the summer passes and the heat accumulates and reaches the inner surfaces of the snow, it starts to advance in the late summers due to the continuous exposure to the sunlight. They start to melt and move forward in the late summers and heavy melting usually lead to floods in the nearby towns and cities.
Answer:
250 H bonds
Explanation:
The Chargaff rule states that a DNA molecule has the following features-
1. Purine binds pyrimidines through hydrogen bond
2. The sum of purine and pyrimidine is equal to 1.
3. Adenine binds thymine always (involve two H bonds)
4. Guanine binds cytosine (involves three H bonds)
In the given question,
guanine bases- 50, therefore, cytosine bases will be 50
H bond will be 50 x 3 = 150 bonds
Similarly,
Adenine bases will be 50 equal thymine which will also be 50
double H bond will be - 50 x 2= 100
Total H bond will be- 250 H bonds.
Thus, 250 H bonds are the correct answer.
