Characteristics of living things
- Correct Answer-
-All are composed of cells
-All obtain energy and use it to develop
-Can sense changes in the environment and adjust in response to change
-Exhibit modifications that represent adaptations to their environment
Levels of Biological Organization
- Correct Answer-atom, molecule, organelle, cell,tissue, organ, organ
system, organism
How are organisms classified?
- Correct Answer-on the basis of their
evolutionary/genetic relatedness
What is the scientific method? What is it's importance in biological
sciences?
- CorrectAnswer-Process used to validate observations while
minimizing observer bias
It's goal is for research to be conduced in a fair, unbiased and repeatable
manner. Thebest way to discover how and why the world works
What is matter?
- Correct Answer-Anything that has mass and takes up space
What is an atom?
- Correct Answer-smallest unit of matter that retains all the chemical
properties of an element. They combine to form molecules which then
form into a solid,gas or liquid

What is the structure of an atom?
- Correct Answer-Nucleus in the center that containsprotons (positively
charged) and neutrons (no charge). The outermost region is called an
electron shell that contain the electrons (negatively charged)
What is an ionic bond?
- Correct Answer-A chemical bond that's formed when an atomtransfers
and electron to another Atom
What is a covalent bond?
- Correct Answer-Results when 2 atoms share electrons inorder to have a
completed outer shell
What is a double covalent bond?
- Correct Answer-Occurs when 2 atoms share 2 pairsof electroms
In order to be an organic molecule it must contain what?
- Correct Answer-Carbon andhydrogen
What are the main groups of organic molecules that build cells and their
parts?
- CorrectAnswer-Carbohydrates, proteins, lipids, nucleic acid
What are the properties of water?
- Correct Answer-Its attraction to polar molecules.High-specific heat.
High heat of
vaporization.The
lower density of ice.
High polarity.
, Academicachiever - Stuvia US
Carbohydrates
- Correct Answer-Broken down to glucose to provide energy.
What are the different kinds of carbs?
- Correct Answer-Glucose= monosaccharide thatserves as blood sugar
Sucrose= disaccharide which is table sugar
Polysaccharides= include starch, which stores
energy in plantsGlycogen= stores energy in animals
Cellulose= makes up the structure of plant cell walls
Protein
- Correct Answer-macromolecule that contains carbon, hydrogen, oxygen,
andnitrogen; needed by the body for growth and repair
Lipid
- Correct Answer-Energy-rich organic compounds, such as fats, oils, and
waxes,that are made of carbon, hydrogen, and oxygen.
Serve as a long term energy source
Nucleic acid
- Correct Answer-macromolecule containing hydrogen, oxygen, nitrogen,
carbon, and phosphorus
Form DNA which acts to store genetic information
What is the cell theory?
- Correct Answer-All living organisms are made up of cellsThe cell is the
smallest structural and functional unit of all living organisms
All cells arise from pre-existing cells
Ribosome
- Correct Answer-Makes proteins
