Explanation:
Intracellular receptors are a type of receptors located inside the cell, specifically in the cytoplasm or nucleus. When intracellular receptors are activated by ligands called SIGNALLING MOLECULES, they change shape and regulate genetic expression in the nucleus i.e. they induce turning on and off in a gene.
However, signalling molecules that activate intracellular receptors are usually hydrophobic hormones because they need to easily diffuse through the cell membrane and bind to the receptors located internally. Example of these hydrophobic signal molecules are STEROIDS.

No they do not since whilst the parents may exhibit a certain trait this does not mean that they are necessarily homozygous for that trait, and thus if for example we had two heterozygous individuals who had brown eyes, with B denoting brown eyes as the dominant trait and b denoting blue eyes as the recessive trait, their offSpring could have the genotypes BB, Bb or bb - we can see here that whilst the chance of having brown eyes is higher, the offspring may have either brown or blue eyes.
Answer:
Many scientists use dichotomous keys to identify plants, animals, and other organisms. They may also use dichotomous keys to identify species, or to determine whether a particular organism has been identified and described before. However, dichotomous keys are not used only to identify organisms.
