Answer:
93 billion light years
Explanation:
The proper distance—the distance as would be measured at a specific time, including the present—between Earth and the edge of the observable universe is 46 billion light-years (14 billion parsecs), making the diameter of the observable universe about 93 billion light-years (28 billion parsecs).
Option B- They play a minor role in biological and geo-chemical cycles is the right answer.
Marine microbes are tiny, single-celled organisms that live in the ocean. They play a major role in biological and geo-chemical cycles.
Using a microscope
Explanation:
A microscope is a scientific device used for magnifying and studying very tiny features.
It was invented by Anton Von Leeuwenhoek in the 17th century.
- A unicellular organism is an organism made up of a single cell.
- A multi-cellular organism is made up of several cells.
- A cell is a very small microscopic structure.
- It is usually described as the fundamental unit of life.
- Due to its small size, the naked eyes cannot see it

Answer:
Each three base sequence of the mRNA, called a codon, is read by the ribosome, and the appropriate amino acid is inserted into the growing protein. If you have only a DNA sequence, to find the corresponding amino acids first transcribe your DNA sequence into an RNA sequence using complimentary base pairing.
