100
Which process involves crossing over and independent assortment to bring about genetic diversity, meiosis or mitosis?
Meiosis
100
This is known as the passive transport of water from an area of high concentration to low.
Osmosis
100
This macromolecule contains Carbon oxygen, nitrogen, hydrogen, and phosphorus and is found in DNA.
Nucleic Acids
100
DNA Replication occurs in this stage of interphase
S Phase
100
This organelle is responsible for making proteins.
Ribosome
200
Which process does not involve homologous chromosomes pairing or the formation of a bivalent?
Mitosis
200
Active transport requires ____________ in order to occur, while passive transport does not.
Energy
200
This macromolecule is used in the plasma membrane and has a carboxylic acid group (COOH) and a long carbon backbone.
Lipids
200
After being unzipped, this enzyme places a primer before DNA polymerase can begin copying.
RNA Primase
200
This organelle modifies and packages proteins in vesicles before leaving the cell through exocytosis
Golgi Apparatus/Body
300
Crossing over occurs at this structure
Chiasma
300
Which type of cytosis sends vesicle out of the cell, and which type sends vesicle into a cell?
Exocytosis and Endocytosis respectively.
300
Dehydration Synthesis of saccharides will lead to what? (Give two names for this polymer)
Carbs, Sugars, of Polysaccharides
300
DNA replication is referred to as this, since older strands are used as templates to make new strands and double helixes.
Semi Conservative
300
This organelle is found typically in plant cells, and helps make sugars like glucose out of sunlight.
Chloroplasts
400
Describe the difference between the products of mitosis and meiosis in terms of # of cells, amount of DNA, and amount of genetic diversity in DNA.
Mitosis --> 2 cells, identical in DNA, same amount of DNA as regular cell. Meiosis --> 4 cells, genetically different, 1/2 DNA of a regular cell.
400
What will occur if a cell with 50% water is places in a solution of 80% water? Use the terms intracellular and extracellular, and explain the size change in the cell (if any)
Water will move from extracellular to intracellular, cell will grow in size.
400
Lugol's Solution (Also known as iodine, or lugol's iodine, or iodine solution) is mixed with a solution which contains starch. What color would we expect it to turn?
Black or dark purple
400
Give 2 reasons DNA replication is important.
For cells to divide (cell cycle), for cells to do meiosis so we can reproduce, for interphase.
400
Name two organelles you would expect to find a prokarytik cell
DNA, Ribosomes, Plasma Membrane, Pilli, Flagella
500
Which process produces haploid cells? Which process produces diploid cells?
Meiosis --> Haploid Cells Mitosis --> Diploid Cells
500
Each of the following statements are true about bulk transport in cells EXCEPT A) Endocytosis brings material into a cell by forming inward folds of the cell membrane. B) Exocytosis is accomplished by placing material in a membrane-bound vesicle which 
fuses with the plasma membrane and expels its contents. C) Phagocytosis and exocytosis involve bringing substances into the cell. D) Exocytosis and endocytosis are processes that involve vesicles.
C, exocytosis does not involve bringing in the cell.

Imagine there is the following meal in front of you in thanksgiving: Roasted turkey, smooth mashed potatoes, stuffing, cranberry sauce, and pumpkin pie. Name TWO macromolecules you would expect to find in this meal, where from, and the two tests you would use to find them.
Starch --> Lugol's Potatoes or pie Glucose --> Benedicts (Pie or cranberry sauce) Protein --> Biuret's (Turkey) Sudan III --> Lipids (any)

Which of the following is not due to DNA replication? A) Individual cells may grow to an unlimited size B) Skin cells are able to divide B) Frogs are able to produce ovaries and sperm C) DNA can be copied during S Phase
A

A biologist is examining an organelle with an electron microscope. She observes a continuous network of membranes. The tubed membranes are in contact with the nucleus and have small, round structures on the outside of the membranes. Which cell organelle is being observed?
The ROUGH Endoplasmic Reticulum
