What is the difference between anaerobic and aerobic organisms?
-Aerobic organisms need oxygen for their life activities.
-Anaerobic organism don’t need oxygen for their life functions.
What is an organelle?
An organelle is a tiny cell structure that carries out a specific function within the cell.
What is a nucleic acids?
A large molecule made up of carbon, oxygen, nitrogen, and phosphorus.
What is nutrition?
The life activity by which your body gets food and changes it into a usable form is called nutrition.
What is chemical bonding?
Elements combine to form compounds by a process called chemical bonding.
Who was Anton van Leeuwenhoek?
A dutch naturalist who worked in the 1600s. He developed the first simple microscope. This microscope was just a single lens but it enabled him to examine drops of pond water. He drew the organisms he saw. These were thought to be the first drawings of microscopic light.
What is diffusion?
The process by which molecules move from an area of higher concentration of fluid to an area of lower concentration of fluid.

-The basic unit and function of all living things.
Tissue
- Group of similar cells performing the same function.
Organs
- A group of specialized tissues performing one main function.
Organ Systems
- A group of organs that carry on one of the major body functions.
Organism
- Made up of systems that perform its functions.
What is a pH scale?
Measures whether a solution is acid, basic, or neutral.
What types of charges do protons, neutrons, and electrons have?
Protons - Positive
Neutrons - Neutral
Electrons - Negative
What is a monosaccharides?
Monosaccharides are the simplest carbohydrates or simple sugars.
what is the Coarse adjustment
Adjusts the clarity of the specimen (rough)
Where do chemical processes of the organism take place?
The chemical processes of the organism take place inside the organism’s cells.
How do elements differ from one another?
Elements differ for one another by the number of protons, neutrons, and electrons each element has.
What is synthesis?
Living things are able to produce complex substances from simpler substances by the process of synthesis.
What is glucose?
An example of simple sugar is glucose; Glucose helps create energy.
What is a covalent bond?
Is formed when when atoms produce compounds by sharing electrons.
What is osmosis?
The diffusion of water molecules across a selectively permeable membrane.
What are lipids?
Lipids are a source of stored energy in living organisms. (fats and oils)
What is an ion?
Elements combine to form compounds by a process called chemical bonding. The formation of a chemical bond involved either the transfer of electrons from one atom to another to the sharing of electrons between atoms.
What is active transport?
The moving of materials that requires cell energy.The process in which cellular energy is used to move particles through a membrane.
Who was Robert Hooke?
An Englishman who, in 1665, put two lenses together and made a crude compound microscope. He observed slices of cork and saw cell walls.
What are the six basic nutrients and their uses in the body.

Fats and Oils: Source of stored energy for life activities. (2nd source of energy)
Proteins: Build and repair body tissue; also a source of energy.
Vitamins: Necessary for a healthy body.
Minerals: Important in building body parts; help regulate body functions.
Water: Dissolves and transports materials.
What is the chemical formula for sugar?
