Q

Q: Define osmosis.

Study These Flashcards
A

A: Movement of water across a semi-permeable membrane from high to low water concentration.

22
Q

Q: In which direction does water move in a hypertonic solution?

Study These Flashcards
A

A: Out of the cell (toward higher solute concentration).

23
Q

Q: What type of membrane is required for osmosis?

Study These Flashcards
A

A: Semi-permeable membrane.

24
Q

Q: List two factors that affect diffusion rate.

Study These Flashcards
A

A: Molecular size and temperature.

25
Q: What ion do acids donate?
A: H+ ions.
26
Q: What pH range is considered acidic?
A: Below 7.
27
Q: Describe the relationship between H+ concentration and pH.
A: As H+ increases, pH decreases.
28
Q: What ion do bases donate?
A: OH- ions.
29
Q: How does OH- affect H+ concentration in a solution?
A: OH- combines with H+ to form water, reducing acidity.
30
Q: What type of bond shares electrons equally?
A: Non-polar covalent bond.
31
Q: Give an example of a polar covalent bond.
A: Water (H2O).
32
Q: What happens during hydrolysis?
A: Breaks molecules by adding water.
33
Q: Define dehydration synthesis.
A: Joins molecules by removing water (H+ and OH-).
34
Q: Why is water considered a polar molecule?
A: Uneven sharing of electrons (O is partially negative, H is partially positive).
35
Q: What are the monomers of proteins?
A: Amino acids.
36
Q: What type of bond links amino acids?
A: Peptide bonds.
37
Q: What is the storage form of glucose in humans?
A: Glycogen.
38
Q: How do you calculate total magnification on a microscope?
A: Ocular lens × Objective lens.
39
Q: What is the field of view used for?
A: Estimating the size of cells under the microscope.
40
Q: What magnification results from a 10x ocular and a 40x objective lens?
A: 400x magnification.
41
Q: Identify the tissue type: cells tall and lining digestive tract.
A: Simple columnar epithelium.
42
Q: Identify the tissue type: found at ends of long bones with glossy matrix.
A: Hyaline cartilage.
43
Q: What does areolar connective tissue look like?
A: Loose network of fibers and cells, lots of empty space.
44
Q: Which muscle tissue has striations and intercalated discs?
A: Cardiac muscle.
45
Q: What are the main cells in nervous tissue?
A: Neurons.
46
Q: What tissue type has no striations and is found in the digestive tract?
A: Smooth muscle.
47
Q: What type of epithelium lines kidney tubules?
A: Simple cuboidal epithelium.
48
Q: What type of cells can be seen in a cheek cell sample?
A: Epithelial cells.
49
Q: In which root tip region can mitosis be observed?
A: Meristematic region (root tip).
50
Q: What organelle is visible in both cheek and onion cells?
A: Nucleus.
51
Q: Why do red blood cells lack nuclei?
A: To maximize space for hemoglobin and oxygen transport.
