The _________________ is the most frequently asked about structure on Dr. Z’s lecture and lab exams. Hint: she mentions this structure quite frequently in class.

notochord
100

In eukaryotic cells, this network of membranes includes the rough and smooth variants and plays roles in protein modification and lipid synthesis.

Endoplasmic Reticulum

100

A homogeneous mixture of two or more substances is called this.

solution

100

An organism with two identical alleles for a trait is described using this genetic term.

Homozygous

200

This is the site of aerobic oxidative phosphorylation

Mitochondrion

200

The allantois constricts to become the urachus and then the ________________ in the adult.  

median umbilical ligament

200

This organelle contains acid hydrolases and is responsible for breaking down damaged organelles, pathogens, and large molecules.

Lysosome

200

This type of bond forms when electrons are transferred between atoms.

ionic

200

The location of a gene on a chromosome is called this.

Locus

Blood types are an example of several different types of inheritance.   A is dominant to O and B is dominant to O. A and B are ___________ to each other.

codominant

300

The ___________________ becomes the valve of the foraman ovale.

septum primum

300

These protein filaments provide shape and support for the cell and help with movement and division.

Cytoskeleton

300

This state of matter has a definite volume but no definite shape.

liquid

300

Noncoding regions of eukaryotic genes that are removed before translation are called this.

Introns

True or False:  Rabbits exhibit coprophagy, in which they eat certain forms of their feces

True

________________________ is the process that gives rise to all three germ layers.

Gastrulation

400

This process allows cells to engulf large particles or even whole bacteria through membrane folding.

Phagocytosis

400

This type of reaction releases heat to the surroundings.

Exothermic reaction

400

This phenomenon occurs when one gene influences multiple, seemingly unrelated traits.

Pleiotropy

500

Name a pyrimidine

C, U, or T

Incorporation of this structure during cranial/caudal and lateral body wall folding gives rise to the foregut, midgut, and hindgut.

Yolk Sac

500

This intraceullar structure breaks down hydrogen peroxide using enzymes such as catalase.

Peroxisome

500

This term refers to the highest occupied energy level of an atom.

Valence shell

500

This regulatory region on DNA is where RNA polymerase binds to initiate transcription.
