Lab Midterm

Normal range for body temperature

37 C/ 98.6 F

Normal range for respiration rate

12-20

Normal range for pulse rate

60-100 BPM

Stimulus

A change in the environment that disrupts homeostasis

Response

The action that restores homeostasis

How did we test for sugar? What reagent did we use?

Benedict's reagent

How do we test for starch?

Iodine

Simple Diffusion

Movement of molecules directly through the cell membrane from high to low concentration

Facilitated (Selective) Diffusion

Movement of larger or charged molecules through specific proteins in the membrane from high to low concentration

Active Transport

Movement of molecules from low to high concentration using ATP (energy) and transport proteins

Osmosis

Movement of water across a semipermeable membrane from an area of low solute concentration to high solute concentration

The main solutions in the human body related to osmotic pressure are:

Blood plasma, Interstitial fluid, Intracellular fluid

Osmolarity

The total concentration of solute particles in a solution

Tonicity

How a solution affects water movement into or out of cells. It compares the solute concentration outside the cell to the inside.

Hypotonic Solution

Solute is lower outside the cell/ cell may burst

Hypertonic Solution

Solute is higher outside the cell/ cell shrinks

Isotonic Solution

Equal solute inside and outside

Normal hemoglobin range for men:

13-17 g/dl

Normal hemoglobin range for females:

12-15 g/dl
