Answer:D( Ribosomes
Explanation: Since most enzymes are proteins, it will be produced at the ribosomes. It may have an active and an inactive form. Which means another substance Will turn it on or off.
A "ring of Life" is more appropriate to describe the relationship between archaea, bacteria, and eukaryotes than a “tree of life “, because each group of single-celled prokaryotic organisms produces something that is a necessity to another group of single-celled prokaryotic organisms. so therefor it is not like a tree of life which is more of a hierarchy than an everyone, and everything is equal Ring of Life.
The best answer is C.
Plant cells are surrounded by a cell wall and have chloroplasts whereas animal cell do not.
The cell wall is a covering that is rigid whose main purpose is to protect the cell and give structural support as well shape to the plant cell. The equivalent of a cell wall in animal cell is the cell membrane, which has distinct differences from the plant cell wall.
Chloroplasts are plant cell organelles which carry out photosynthesis by which plants make their own food. These are absent from animal cells because animals do not make their own food, they ingest it from external sources.
Answer:
Transfer RNA (tRNA) is a small RNA molecule that participates in protein synthesis. Each tRNA molecule has two important areas: a trinucleotide region called the anticodon and a region for attaching a specific amino acid. During translation, each time an amino acid is added to the growing chain, a tRNA molecule forms base pairs with its complementary sequence on the messenger RNA (mRNA) molecule, ensuring that the appropriate amino acid is inserted into the protein.
