The organelle that is used as a storage in a cell is called a __________. Vacuole
Ribosome make __________ in the cell. Proteins
This organelle is located around the nucleolus and helps control what things, like proteins can enter and leave the nucleolus. It is sometimes called the mail system. Endoplasmic Reticulum

An organism's phenotype is its: Physical appearance
An organism's genotype is its: Allele combination
An allele whose trait always shows up in an organism when the allele is present is a: Dominant allele
An allele whose trait only shows up in an organism when there are two identical alleles is a: Recessive allele
A tool that applies the laws of probability to genetics is a: Punnett square
When an organism has two identical alleles for a trait, the organism is said to be: Homozygous for that trait
When an organism has two diff. alleles for a trait, the organism is said to be: Heterozygous for that trait
