Explanation:
Batesian mimicry is when an organism uses colors or symbols that other organisms regard as dangerous. These organisms use their scary appearance to appear as more of a threat than they really are, such as the viceroy butterfly, which looks like a poisonous monarch but is actually harmless.
The correct answer is uracil.
<span>Uracil is one of the pyrimidine nucleotide bases which is the component of nucleic acid-RNA. In RNA, uracil binds to adenine via two hydrogen bonds (complementary binding). Uracil is not found in DNA, it is replaced by thymine because it is thymine’s demethylated form.</span>
Answer:
He examined covered and uncovered meat to determine that maggots came from eggs.
Explanation:
Prior to Redi's experiment and other supporting experiments, it was formerly believed that life could emanate from non-living things, for example, the generation of maggots from rotting meat.
In 1668, a scientist called Francesco Redi disproved the idea of spontaneous generation. He did this when he experimented that the maggots from meats are only as a result of eggs laid by flies when they perched on the meat.
He placed the meat in two jars; an uncovered jar and another in a covered jar with a cloth, after several days, the uncovered jar had maggots on the meat, while the covered jar had no maggot on the meat, but on the cloth. With this experiment, he was able to demonstrate that the maggot arose from the eggs of the flies, not the meat itself which is nonliving and hence, disproved the idea of spontaneous generation.
