A eukaryote has a spherical shape, lacks a cell wall, and has vacuoles, chloroplasts, and multiple flagella. Referring to the Eukaryote Dichotomous Key from your lab manual, what is the identity of this cell? Eukaryote Dichotomous Key 1a. The cell has a spherical shape. …Go to 2. 1b. The cell has a cube-like shape. … Go to 4. 1c. The cell has a column-like shape. … Go to 5. 1d. The cell has an elliptical, or oval shape. … Go to 6. 1e. The cell has no rigid structure. … Go to 8. 2a. The cell has a cell wall made of silica, and has vacuoles and chloroplasts. … Example: diatom 2b. The cell has a cell wall made of chitin. It has vacuoles, but lacks chloroplasts. … Example: Saccharomyces cerevisiae (yeast) 2c. The cell lacks a cell wall. … Go to 3. 3a. The cell has centrioles. … Example: hepatocyte (liver cell) 3b. The cell has vacuoles, chloroplasts, and multiple flagella. …Example: Chilomonas 4a. The cell has a cell wall made of silica. It has vacuoles and chloroplasts, but lacks centrioles. …Example: diatom 4b. The cell has a cell wall made of cellulose. It has vacuoles, chloroplasts, and centrioles. …Example: root tip cell 4c. The cell lacks a cell wall, but has centrioles. …Example: skin cell (cubiodal epithelium) 5a. The cell has a cell wall made of silica. It also has vacuoles and chloroplasts, but lacks centrioles. …Example: diatom 5b. The cell has a cell wall made of cellulose. It has vacuoles, chloroplasts, and centrioles. …Example: cork cell 5c. The cell lacks a cell wall and centrioles. …Example: skin cell (columnar epithelium) 6a. The cell has a cell wall made of cellulose, and has vacuoles and cilia. …Example: plasmodial slime mold (flagellated stage) 6b. The cell lacks a cell wall. … Go to 7. 7a. The cell has centrioles. … Example: myocyte (muscle cell) 7b. The cell has vacuoles and cilia. … Example: Paramecium 8a. The cell has centrioles. … Example: phagocyte (immune responder cell) 8b.

Diagram (a) on top shows reaction rate vs. temperature (oC). Diagram (b) on bottom shows reaction rate vs. pH. Which curves were generated using an enzyme isolated from a human stomach? Note: numbers on the X axis of the temperature graph (a) are: 0, 20, 40, 60, 80 , 100.  

____ occurs when there is a removal of electrons and/or hydrogen atoms from a substrate.

Which is most closely associated with the Calvin cycle reactions?

In lab, a dialysis tubing was filled with a solution containing 1% starch and 15% glucose. The tubing was immersed in a beaker containing water and Lugol’s iodine solution (0.1% Lugol’s iodine).  After 30 minutes, students tested the contents of the tubing and the contents of the beaker for glucose using the Benedict’s reagent. Both the tubing and the beaker solutions tested positive. This result leads you to conclude that:

Which solution is neutral?

Explain what it means for a solution to be hypotonic. Then explain what would happen to a cell if you placed it into a hypotonic solution. Be sure to discuss which direction water would flow (into or out of the cell).
