Earth's history. In the worst one, 250 million years ago, 96 percent of marine species and 70 percent of land species died off. It took millions of years to recover.
Human impact can cause population decline as previous limit are removed. Carnivores prey on animals.
Answer: The complementary strand is TCC- GAT - TTG
Explanation: During DNA replication, each strand of the DNA serves as a template for the synthesis of a new strand, thereby producing two new DNA molecules, each with one new strand and one old strand. A template is a DNA strand that would allow nucleotide molecules to be lined up in a specific order and be joined to create another DNA with a unique sequence. This results in creation of a double stranded DNA in which each strand is complementary to the other. In nucleotide base pairing, Guanine pairs with Cytosine while Thymine pairs with Adenine.
G = C while T = A.
An ectotherm gets its heat from external sources
