Answer:
Explanation:
The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
The bases in DNA pair by chemical interactions is adenine and thymine form two hydrogen bonds, while cytosine and guanine form three hydrogen bonds.
What is the use of two strands?The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
Adenine and thymine form three hydrogen bonds, while cytosine and guanine form two hydrogen bonds. Adenine and thymine form covalent bonds, while cytosine and guanine form hydrogen bonds.
Adenine and thymine form two hydrogen bonds, while cytosine and guanine form three hydrogen bonds. Adenine and thymine form hydrogen bonds, while cytosine and guanine form covalent bonds.
Therefore, The bases in DNA pair by chemical interactions is adenine and thymine form two hydrogen bonds, while cytosine and guanine form three hydrogen bonds.

If two air masses have the same relative humidity of 60 %, which one contains more water vapor?
a. The one with the higher temperature
b. Both would have the same amount
c. The one with higher relative humidity
d. The one with the lower temperature
b. Both would have the same amount
Option b. Both contain a similar amount.
Given that,
The two masses should have a similar relative humidity of 60%.We need to find out which have more water vapor.Based on the above information, we can say that since both two masses contain the same humidity i.e. 60% so it means that they have the same amount.
Therefore the option b is correct.

radium in an element found in group 2 and period 7. in a normal radium atom, how many energy levels contain at least one atom?
A. 1 B.6 C.7 D.8
Answer:
the answer is d
Explanation:
In a normal radium atom, there are 7 energy levels.
The periodic table is arranged in groups and periods. The elements in a group have the same number of valence electrons while the elements in the same period have the same number of energy levels.
Radium is an element in period 7. The fact that it is in period 7 implies that it has 7 shells or energy levels. Hence, in a normal radium atom, there are 7 energy levels, each containing electrons.
