Lab 1 Amazing, Wild, Wonderful Water

What type of covalent bond is formed between water

polar covalent

emergent properties of water

cohesive, adhesive, expansion when freezing, and versatility as a solvent

Cohesion

linking of like-molecules, often by hydrogen bonds

adhesion

clinging of water to another substance by hydrogen bonds

stomata

minute aperture structures found of leaf skin also known as epidermis. open and close for gases

dependent variable

The outcome factor; the variable that may change in response to manipulations of the independent variable. (the flower's reaction to the water, like dying, or the color it turned into)

independent variable

variable that is manipulated (the substance added to the water)

control group

In an experiment, the group that is not exposed to the treatment ( the carnation in regular water)

surface tension

A measure of how difficult it is to stretch or break the surface of a liquid (cohesion)

plasmolysis

When a cell loses water when placed in a hypertonic solution. (seen in elodea)

acid

releases H+ ion

base

decreases H+ ion

buffer

regulates pH. Gives an H+ when low and removes H+ when too high

OTC deficiency

excess ammonia

Homeostasis

regulation of body's functions (presence of buffers in the body)
