Hydrophobic

Substance that does not mix with water repels water.

Hydrophilic

Substance that dissolves and mixes with water.

Cohesion

The attraction between molecules of water.

Adhesion

The attraction between molecules of different substances, allowing them to cling together.

High specific Heat

The amount of heat required to raise the temperature of one gram of a substance by one degree Celsius, which helps maintain stable temperatures in bodies of water.

Water is less dense as a solid.

This phenomenon occurs because the hydrogen bonds in ice form a crystalline structure that is less compact than liquid water, causing ice to float.

Water is a Universal Solvent.

Water can dissolve most substances.

Covalent bond.

A type of chemical bond formed when two atoms share one or more pairs of electrons.

Ionic Bond.

A bond formed based on the attraction of opposite charges.

Hydrogen Bond.

weak attraction between a hydrogen atom (which is covalently bonded to a more electronegative atom, like oxygen or nitrogen) and another electronegative atom in a neighboring molecule.

Functional group

Groups of atoms that occur within molecules and center specific chem properties to the molecules.

Microscope

A microscope is a tool that magnify something small or large a microscope is used to look at microscopic things usually.

Polar molecules

In a polar molecule electrons are not shared equally.

Non-Polar molecules

Non-Polar molecules do share equally.

Dependent variable

The dependent variable is what is being measured during a experiment.

Independent variable.

Independent variable is the variable that is being manipulated or changed in the experiment.

Experimental design

The steps u take to answer the question.

Control group.

The control group is the neutral group.

Hypothesis.

A hypothesis is a prediction on what you think is going to happen.

Positive feedback loops.

A positive feedback loop is when a loop continues and boosts something in the direction its going.

Negative feedback loop.

It is like a positive feed back loop but with a on and off switch.

Response to stimuli

Type of response: Negative (Away) Postivie (Towards)

Divide

Reproduction

Growth dev

Getting larger in size throughout life

regulation

Internal functions are cordnated within systems, groups of organs working together

homeostasis

Having equal (equilibrum in the body)
