Answer:
I think a gene is something that makes look how we look
Explanation:
Living beings -reproduce , grow and develop, made of cells , store and use energy, adapt to their environment , responds to their environment or stimuli
Non living beings- do none of the above they do not eat , grow , develop, have cells store or use energy , they do not adapt to their environment, and they don’t respond to their environment or stimuli
The statement "When levels of the amino acid are high, it binds to the repressor, allowing synthesis of this amino acid to proceed" (A).
E. coli needs amino acids to survive. It can ingest the amino acid, Tryptophan from the environment. When the levels of Tryptophan are low, it can synthesize Tryptophan by using enzymes that are encoded in five genes. These genes lie next to each other in the tryptophan operon. If tryptophan is available in the environment, E. coli will not synthesize it.
Connective tissues are the tissues that are responsible to connect, support, bind, or to separate out other tissues or organs,that have relatively few cells embedded in an amorphous matrix, often with collagen or other fibers, that includes cartilaginous, fatty, and elastic tissues. Cartilaginous tissues are responsible for the firm, rubbery matrix that provides flexibility. These tissues give shape to the external ear, the larynx (voice box) which is the most easily palpated cartilages in the body, and to the tip of the nose.
