This question had choices. These are the missing choices.
A) Scientists made careful observations of behavioral patterns.
B) The DNA mutation rates for both species was calculated and compared.
C) Scientists made a detailed analysis of the fossilized bones of each species.
D) The enzyme activity of each species was studied to determine similarities in metabolism.
My answer:
C) Scientists made a detailed analysis of the fossilized bones of each species.
This determination is the only feasible thing to do since dinosaurs are long dead and choices A, B, and D requires the subjects to be alive.
<span>The influenza pandemic of 1918-1919 killed more people
than the Great War, known today as World War I (WWI), at somewhere between
20 and
40 million people. It has been cited as the most devastating epidemic in
recorded world history. More people
died of influenza in a single year than in four-years of the Black Death
Bubonic Plague from 1347 to 1351. Known as "Spanish Flu" or "La
Grippe" the influenza of 1918-1919 was a global disaster. </span>
Answer: Colonial organisms are the result of many identical individuals joining together to form a colony. These cells are partly dependent on each other to start with. But, later evolutionary events resulted in the obligatory relationships among them resulted in multicellularity.
8 protons because a element always has the same number of protons as its atomic number
Answer:
Base substitution mutation
Explanation:
Mutation is the alteration or change that occurs to the sequence of a gene caused by a mutagen (chemicals) or spontaneously-induced. Depending on how the mutation occurs, it is of different types. The mutation shown in this question is as follows:
ATCGGCTTAACG to ATCGGCTAAACG
This type of mutation is called SUBSTITUTION MUTATION. Substitution mutation is a type of mutation that involves the replacement of one or more nucleotide base by another. In this original sequence; ATCGGCTTAACG, the eight base T was replaced by base A in the sequence, hence, it is a substitution mutation.
