Answer: they are all prokaryotes
Explanation: because they all lack a nucleus to retain their DNA
Most proteins in living organisms are composed of 40 amino acid residues in total, and nine of those are crucial for human health.
Which majority of amino acids make up proteins in living things?
- Only twenty different amino acids, each with a distinct side chain, make up proteins. Different chemistries can be found in the side chains of amino acids. The majority of amino acids contain side chains that are nonpolar.
- There are nine essential amino acids:
- tryptophan
- valine
- isoleucine
- leucine
- lysine
- methionine
- phenylalanine
- threonine
- methionine
What Constitutes Proteins?
- Amino acids are the basic units of proteins. They are tiny chemical compounds with an alpha (central) carbon coupled to an amino group, a carboxylic acid group, hydrogens, and a changeable element known as a side chain.
- A protein is made up of a lengthy chain of amino acids that are connected by peptide bonds. The biological process that links the carboxyl unit of one amino acid towards the amino group of a nearby amino acid results in the extraction of a water molecule, forming peptide bonds. The main structure of a protein is thought to be its linear amino acid sequence.

Answer: Racial classification
Explanation: Racial classification can be defined as the way humans are classified based on their physical and social traits which they have such as how they look, their skin color, hair texture, the native languages they speak.
Scientists used racial classification to learn how unique and different humans are.
Answer:
the respective means of growth within an organism varies from organism to organism. For instance, multicellular organisms grow via a process of cellular division known as mitosis, while others (being unicellular) grow or reproduce colonially-speaking via a process called binary fission.

Answer:
C
Explanation:
Hybrid electric vehicles are powered by an internal combustion engine and an electric motor, which uses energy stored in batteries. A hybrid electric vehicle cannot be plugged in to charge the battery. Instead, the battery is charged through regenerative braking and by the internal combustion engine.
