What is an effect of adaptive radiation?
A. Mass extinction
B. Geographical isolation
c. Many new species form
D. The rate of speciation decreases

B! Many new species form.

Explanation:

Adaptive radiation refers to the process by which animals diversify rapidly from the ancestral species into different forms especially when resources are abundantly available. The effect of adaptive radiation is the emergence of new species, which exhibit different morphological and physiological traits.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.

i'd say that the moon rock is about 2.2 billion years old.
