Passive transport:
For simple diffusion = fatty acids, amino acids, steroid hormones (because they’re non-polar)
Facilitated diffusion = N2 and Cl-
Like D. Codon is the answer
Answer;
a segment of chromosomal DNA
Explanation;
A gene is a hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes.
It is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins.
Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.
The things that birds have attached to their bodies called their wings, a left one and a right one, cause them to have the ability to fly.
