A simple example to illustrate genotype as distinct from phenotype is the flower colour in pea plants (see Gregor Mendel). There are three available genotypes, PP (homozygous dominant), Pp (heterozygous), and pp (homozygous recessive).
Vacuoles do /not/ digest molecules.
Well the nervous system divides into the central nervous system (CNS) (brain and spinal cord) and the peripheral nervous system (PNS) (everything else). From there, the CNS divides into the autonomic (ANS) (reflex functions) and the somatic (SNS) (voluntary movement) nervous systems. The ANS subdivides into the sympathetic (SANS) (fight or flight) and parasympathetic (PSNS) (rest and digest) nervous systems. Not sure exactly what the question is referring to, but this is a basic layout of all of the main nervous systems.
Answer:
Umm...I'm not sure if this is a question where there is MC but if not, the the answer would most likely be, "By actually doing then saying"
Explanation:
A Multi-Celled organism has many cells (more than one). Examples would be plants, humans and animals/mammals.
A Single-Celled organism only has one cell that makes up it's entire self. Examples would be bacteria and archaea.
