Answer: Purine; is equal to; pyrimidine
Explanation:
When a segment of DNA is examined then the nucleotide in one DNA molecule, it will be expected that the sum of purine in one strand will be equal to the sum of the pyrimidine in the other strand.
Adenine combines with Thymine and Cytosine combines with Guanine in 1:1 ratio.
More specifically the ratio of purine is to pyramidine is 1:1 in an organism. This pattern is seen in both the strands of the DNA.
Answer:
pioneer species
Explanation:
Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support plants.
<span>The correct answer is A. atoms. Atoms are studied by physics and chemistry, not by ecology. Ecology studies organisms, populations, and the earth in terms of climate, pollution prevention, natural habitats and biomes, and all kinds of similar things that are related to living on earth. Atoms are irrelevant for the study of ecology.</span>
