There are five different types of nucleotide bases found in living things. which is an accurate comparison of the bases found in bears and the bases found in raccoons? a. bears and raccoons use the same bases , but in different order . b. bears and raccoons use the same bases in the exact same order . c. bears and raccoons have only one base in common . d . bears and raccoons do not use any of the sand bases .

A. Bears and raccoons use the same bases , but in different order .

Explanation:

The type of the nitrogenous bases present in nucleotides of all living beings are same irrespective of their species type. Since different genes differ from each other in total number of bases and their order, combinations of the five bases produce a large number of genes. Bears and raccoons belong to different species, they have same bases but different order of bases results in presence of different genes in their genomes.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
