Answer:
Plates are floating and sliding on the asthenosphere. After millions of years the plate movement allows continents to move.
Explanation:
Continents lie on tectonic plates that are constantly shifting, which eventually caused the continents to change location.
Answer:
The Respiratory system allows entry of oxygen into the body and release Carbon Dioxide. The Oxygen travels across lung tissue into blood vessels and the blood carries the oxygen around the body. Thus the Respiratory and Circulatory system work together in gas exchange which is vital in Homeostasis
Answer:
Phosphate sugar backbone:
The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
Nitrogenous base:
Nitrogen bases are the molecules that make up the steps of the ladders. There are four different nitrogen bases, namely; Guanine, Thymine,Adenine and Cytosine.
Pyrimidines are compounds that make a single 6-sided ring. Examples of pyrimidines are Cytosine and Thymine.
Purines on the other hand make 5-sided and 6-sided rings. Examples of purines are Guanine and Adenine.
The nitrogen bases are helped together through hydrogen bonds.
Hydrogen Bonds:
A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.

Explanation:
water vapor
Answer: The maximum number of amino acids that could be coded is 2
Explanation:
- A codon in this microorganism is 2 bases instead of 3 bases .
- In order to encode a protein a sequence requires a start and stop codon
- If you assume no start codon: then only 2 bases would make up the stop codon.
- This leaves 4 bases which is 2 codons. This would encode 2 amino acids.
- If you assume a start and stop codon, then each codon would be allocated 2 base pairs each = 4 base pairs
- This only leaves 2 base pairs, a single codon which would only code for 1 amino acid
