Answer: A variety of substances will dissolve oil, including gasoline and carbon tetrachloride -- both of which have non-polar molecules. Acetone is a special class of solvent called “dipolar aprotic” that, depending on the circumstances, can act as a weak acid or base; it dissolves oil and mixes with water as well.
Explanation:
I’m not exactly sure, but I’m thinking it may be A . I just learned about this unit previously .
The synthesis of thyroid hormones requires the iodination of tyrosine molecules and the combination of two iodinated tyrosine residues
From this one migrant species would come many -- at least 13 species of finch evolving from the single ancestor.
This process in which one species gives rise to multiple species that exploit different niches is called adaptive radiation. The ecological niches exert the selection pressures that push the populations in various directions. On various islands, finch species have become adapted for different diets: seeds, insects, flowers, the blood of seabirds, and leaves.
The ancestral finch was a ground-dwelling, seed-eating finch. After the burst of speciation in the Galapagos, a total of 14 species would exist: three species of ground-dwelling seed-eaters; three others living on cactuses and eating seeds; one living in trees and eating seeds; and 7 species of tree-dwelling insect-eaters.
Scientists long after Darwin spent years trying to understand the process that had created so many types of finches that differed mainly in the size and shape of their beaks.
Answer:
chloroplasts
Explanation:
photosynthesis takes place inside plant cells in small things called chloroplasts ( mostly found in the mesophyll layer) contain a green substance called chlorophyll
