1

• When analyzing a specimen under a microscope, why do we stain the specimen?

Answer: Most cell parts appear clear under the bright light of a microscope. Staining them gives them color and therefore makes it easier to see. BACK

2

• When a chromosome copies itself, the copy is referred to by this “relative” term.

Answer: sisterBACK

• This membrane junction are impermeable junctions that bind cells together into leakproof sheets?

Answer: tight junctions BACK

4

• This is a nonfunctioning unit in a cell.

Answer: inclusion.BACK

5

• This type of tissue is also known as fat, and it is essentially an areolar tissue in which fat cells predominate.

Answer: Adipose TissueBACK

6

• This is another name for a red blood cell.

BACK

7

• Describe what happens during diffusion.

Answer: Substances move from areas of high concentration to areas of low concentrations until eventually there is an equal concentration in all areas.

8

• When analyzing a specimen under a microscope, why must the sample be very thin?

Answer: This is to allow light to pass through the sample and to allow only one layer of cells to be observed at a time BACK

9

• In this phase, chromosomes appear as threadlike coils at the start, but each chromosome is copied by the end.

Answer: interphaseBACK

10

• This is the process in which a pressure gradient actually pushes a solute containing fluid from a higher pressure to a lower pressure.

Answer: filtrationBACK

11

• This refers to when a cell moves a large amount of substances out of the cell

Answer: exocytosisBACK

12

• What occurs if a solution is hypotonic and a cell was placed into it?

BACKAnswer: The cell would swell and possibly rupture

13

• This is the process during protein synthesis when the DNA is copied by RNA.

Answer: transcriptionBACK

14

• This type of tissue is made up of connective tissue sheets that attach to the body’s skeleton and help the body with movement.

Answer: skeletal muscleBACK

15

• This type of connective tissue forms the cushionlike disks between the vertebrae.

Answer: fibrocartilageBACK

16

• This attached skeletal muscles to bones.

Answer: tendonsBACK

17• This is also known as osseous tissue.

BACKAnswer: bone

18

• This word mean one layer of cells.

Answer: simpleBACK

19

• In this phase, centrioles appear and begin to move to opposite ends of the cell while spindle fibers forms between the poles.

Answer: prophaseBACK

20

• What is the relationship between a triplet and a codon?

Answer: A triplet is a three-base sequence on a DNA molecule. A codon is the corresponding three-base sequence on the mRNA moleculeExample: Triplet on DNA AAT-CGTCorresponding Codon on RNA UUA-GCA

BACK

21

• What type of cell is this?

Answer: macrophage BACK

22

• This broad type of tissue if used for support.

Answer: connectiveBACK

23

• This is a picture of this type of tissue

Answer: stratified squamous BACK

24

• In this phase, chromatids attach to the spindle fibers.

Answer: metaphaseBACK

25• Give two examples of tissues undergoing the aging

process and what happens to the tissue as it ages.

BACK

Answer: epithelial membranes lose their elasticity and began to sagWe begin to “dry out” as exocrine glands become less activeEndocrine glands produce less hormones so the body processes they control become less effectiveBones become porous and weakerMuscles begin to atrophy (deteriorate)

26

• This refers specifically to when liquid material is taken into the cell.

Answer: pinocytosisBACK

27

• This broad type of tissue is used for control.

BACKAnswer: nervous

28

• What is area O called

Answer: Mitochondria BACK

29

• What occurs if a solution is hypertonic and a cell was placed into it?

Answer: it would shrinkBACK

30

• This type of tissue help to insulate and protect the delicate neurons.

Answer: Supporting cells of the nervous tissue BACK

31

• In this phase, chromatids separate and begin to move to opposite ends of the cell.

Answer: anaphaseBACK

32

• What is inflammation and how does it help the healing process.

Answer: A swelling of a tissue. It is used by the body to keep the injured area from moving and thus prevents further damage BACK

33

• This is a fragile, transparent barrier that consists of two lipid layers arrange “tail to tail”

Answer: plasma membraneBACK

34

• small, dark-staining round body where ribosomes are assembled

Answer: nucleolusBACK

35

• This is what the fluid inside the cell is referred to.

Answer: intracellular fluidBACK

36

• These detoxify the cell of poisonous materials and deactivate free radicals using oxidase enzymes.

Answer: peroxisomesBACK

37

• This is a cell that gathers information and controls body functions.

BACKAnswer: nerve cells (nueron)

38

• In this phase, two nuclei form and the chromosomes appear as chromatin.

Answer: telephaseBACK

39

• This cell type covers and lines body organs.

Answer: epithelial cells BACK

40

• These are the “wires” that help to resist pulling forces on the cell.

Answer: intermediate filamentsBACK

41

• Why are stratified epithelial tissues better for protection purposes than simple epithelial tissues?

Answer: Stratified epithelial tissue has multiple layers of cells, which means there are more cells to absorb the damage BACK

42

• This is the female cell of reproduction.

Answer: oocyteBACK

43• Name this type of cell

BACKAnswer: Epithelial Cells

44

• This is a slick membrane that lines the ventral body cavity and covers the organs in the cavity.

BACKAnswer: serosae

• The lower surface of an epithelial tissue is known as this.

BACKAnswer: the basement membrane

46

• These are tiny fingerlike projections that greatly increase the surface area for faster absorption

Answer: microvilliBACK

47

• In this phase, cell membranes moves inward to create two daughter cells.
