If someone has "homozygous" alleles, what does that mean?
The two letters are the same, like TT or ff.

What are the shapes and names of the types of bacteria?
Cocci - round Bacilli - rod shaped Spirilla - spiral shaped
400
This structure houses the genetic material within the cell.
the nucleus

What is the difference between telophase and cytokinesis?
In telophase the cell shows a dividing wall developing but in cytokinesis the two cells have separated.
400
When do recessive traits show up in the offspring?
When both recessive alleles are present, like tt.

Describe how you protect yourself from a virus and a bacteria.
A virus, you can get a vaccine. A bacteria, you can take an antibiotic.

Name two important jobs the cell wall has.
It keeps the plant upright and it protects the cell.

What are the "tiny threads" called, that stretch between the chromosomes and the centromere?
Spindle fibers

What is the difference between a genotype and a phenotype?
Genotype are the alleles that make up the trait, and the phenotype is the physical trait you see, like freckles.
