Levels of Organization
Structures that carry out specific functions in cells.
What is an Organelle?
Positively charged subatomic particles present in the nucleus of atoms.
What are Protons?
A type of chemical bond that is very weak but causes many of the unusual properties of water.
Water molecules are attracted to other substances.
What is Adhesion?
A type of organic compound that contains monosaccharides such as glucose.
What are Carbohydrates?
All the members of a particular type of organism living in one area.
What is a Population?
A substance made of a group of atoms held together by chemical bonds.
What are Molecules?
A type of chemical bond where atoms share electrons in a way that each atom shares two electrons.
What are Double Covalent Bonds?
Water molecules are attracted to other water molecules.
What is cohesion?
A molecule comprised of a ribose sugar, a nitrogenous base, and three phosphate groups.
What is ATP?
A group of similar cells that perform a common function.
What is a Tissue?
A substance made of joined atoms of two or more different elements and where one of the elements is carbon.
What are Organic Compounds?
A type of chemical bond where atoms share electrons evenly.
What are Non-Polar Covalent Bonds?
Water molecules can climb up trees.
What is Capillary Action?
A type of organic compound that contain amino acids and perform many functions; for example, antibodies, hemoglobin, enzymes, and collagen.
What are Proteins?
A living thing comprised of a single cell.
One of the three basic subatomic particles that has such a small mass that it is not considered significant when calculating the mass of an atom.
What are Electrons?
A neutral Calcium atom has this many valence electrons. Calcium has 20 protons.
What has 2 valence electrons?
The property of water which causes ice to float on water.
What is (Thermal) Expansion?
A macromolecule that contains a double strand of nucleotide polymers.
What is DNA?
All the members of multiple types of organisms living in one area and interacting with each other.
What is a Community?
Atoms of the same element that have different number of neutrons. For example, C-14 and C-12.
What are Isotopes?
The chemical formula for the ionic compound magnesium chloride. Magnesium (Mg) has 12 protons; Chlorine (Cl) has 17 protons.
What is MgCl2?
A substance which, when dissolved in water, causes hydrogen ions to form and causes the resulting solution to have a pH of less than 7.
What is an Acid?
An organic compound comprised of a glycerol backbone and three fatty acid tails and is used for long-term storage of engery.
What is Triglyceride?
