Groups of 3 bases are referred to as codons.
Each codon codes for an amino acid.
A group of amino acids makes a protein.
These proteins are then used to carry out basic life functions
Answer:
The correct answer is - amino acids.
Explanation:
Proteins are made up of amino acids by linking together by the peptide bonds therefore the building blocks of the proteins are amino acids and due to amino acids linked together by peptide bond they called polypeptide chain;
Amino acids are small organic molecules form by the process translation and have a central carbon atom with an amino -NH group, a hydrogen atom, a carboxyl group -COOH, and a side chain.
Rocks, granite, basalt, elements
Answer:
A.Earth's early atmosphere lacked oxygen, which multicellular organisms need to break apart food
Explanation:
One important feature that led to the development of multicellular organisms was the rise of oxygen-producing photosynthetic bacteria. Prior to this development, the unicellular organisms (anaerobes) then present on Earth obtained energy from inorganic fuels.
However, with the presence of oxygen in the atmosphere, a shift was observed as organisms that could obtain energy from the reduction of energy became predominant. This unicellular aerobes later paved way for the evolution of multicellular aerobes.
They look for facts to confirm their hypothesis then they look for patterns in the data .
