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.

Answer:
community
Explanation:
Community refers to a group of populations of different species that live together in a defined habitat. These species exhibit interdependence for one or other resources. It is a level of the ecological organization just above the population and consists of hundreds of different types of organisms of various species.
Butterflies and flowering plants belong to different species. Butterflies are dependent on these plants for food. Therefore, these two together represent two populations of different species living together in habitat and are an ecological community.
