Answer: Option (c) is the correct answer.
Explanation:
Backbone in a nucleic acids strand is made up of sugar molecules attached with phosphodiester bond.
This sugar-phosphate linkage helps in joining of nucleotides in a DNA sequence. Due to this backbone structural framework of nucleotides is formed. In DNA, the sugar is deoxyribose.
Thus, we can conclude that the backbone in a nucleic acids strand is called sugar backbone.
Answer:
930 g
Explanation:
D = m/V Multiply both sides by V
m = VD
<em>Data:
</em>
V = 372 cm³
D = 2.70 g/cm³
<em>Calculation:
</em>
m = 372 × 2.50
m = 930 g
The mass of Al is 930 g.
Atmosphere. You can think of the atmosphere as the outer shell for earth.
No, their specific heats are different. For water, and ice
Yes, this is a balanced chemical equation, and it obeys the Law of Conservation of Mass.
A balanced chemical equation obeys the Law of Conservation of Mass if there are the <em>same numbers of each type of atom on each side of the reaction arro</em>w.
2H₂ + O₂ ⟶ 2H₂O
Let’s check the numbers.
<u>Atom</u> <u>On the left</u> <u>On the right</u><u>
</u>
H 4 4
O 2 2
We have the same numbers of H and O atoms on each side of the reaction arrow.
The equation is<em> </em>balanced and it obeys the Law of Conservation of Mass.
