Explanation:
Helium is a colorless odorless gas. It is lighter than air. It is nonflammable and is only slightly soluble in water. It is chemically inert.
A) heat is related to speed/ energy of molecules so when it is decreased the molecules slow down and stop bouncing around/ loose energy
Hydrogen, Carbon, Nitrogen, and Oxygen all make up amino acids.
The possible result of the founder effect would be loss of genetic variation. The reason why this is so is because by definition, the founder effect is often considered to be the cause for a essened genetic variation in a specie or a certain area where organisms thrive.
Answer:
32%
Explanation:
According to Chargaff in his complementary base pairing rule, he stated that the proportion of purine and pyrimidine bases is equal to 100%
That is, A + T + G + C = 100%
Where A=T and G=C i.e the proportion of each base pair is equal.
Hence, if the Guanine content is 18%, it means the Cytosine content of that DNA molecule must also be 18%. Therefore:
18 + 18 + A + T = 100
A + T = 100 - 36
A + T = 64
If the sum proportion of Adenine and Thymine is 64% and each must contain equal proportions, A or T = 64/2 = 32
Hence, Adenine contains 32%, likewise Thymine.
