Species adapt to their environment using mutations to give them characteristics that better fit their environment over generations
Answer:
Copy of one side of DNA strand is made
mRNA moves to cytoplasm, then ribosome.
mRNA goes through ribosome 3 bases at a time
transfer RNA (tRNA) matches up with the open DNA bases.
tRNA releases the amino acid at the top, which joins the chain of amino acids being produced
Explanation:
The element starts off as 100%. half of 100% is 50% and half of 50% is 25%. the element has emitted 2 times the half life which is 10,000 x 2 = 20,000
the fossil bone is 20,000 years old
Answer:
Please find what occurs in the single nucleotide-pair substitution below
Explanation:
Single nucleotide-pair substitution is a type of point mutation as stated in this question. Point mutation is when one nucleotide base (single) is affected in the sequence. In this single nucleotide-pair substitution, ONE nucleotide base is substituted by another base.
For example, in a DNA sequence that reads: TAA GTC GGG, a mutated sequence affected by single nucleotide-pair substitution will read as follows: TAA GTC TGG. Note that in the last codon (GGG), a single nucleotide G has been replaced by another nucleotide T. Therefore, single nucleotide-pair substitution is said to have occur.
Answer: Endotherms have the highest growth rates and ectotherms the lowest
