Biology Questions

Every ecosystem must have Autotrophs.

The cell carries out the metabolic processes and it grows during interphase.

The cell cycle has three phases that must occur before mitosis, or cell division happens. These three phases are collectively known as interphase. They are G1, S, and G2.

Plants grow in size both in height and in grith. Enlargement  of cells already present cannot contribute much to the growth. Only addition of more and more cells could increase the size of the plant considerably.

3 Nucleotides make up a Codon. 

The nucleotide triplet that encodes an amino acid is called a codon.

Each group of three nucleotides encodes one amino acid.

RNA - ribonucleic acid is a type of nucleic acid. The sugar contained in it is called Ribose.
