Concept 1
What is science?
the systematic study of the structure and behavior of the physical and natural world through observation, experimentation, and the testing of theories against the evidence obtained.
What are the most necessary element for life?
Oxygen
What are the main functions of macromolecule?
The broad functions of the 4 organic macromolecules are:
What is the scientific definition of Fact?
an indisputable observation of a natural or social phenomenon
what is the scientific definition of Macromolecules?
A macromolecule is a very large molecule important to biological processes, such as a protein or nucleic acid. It is composed of thousands of covalently bonded atoms.
What does IV and DV stand for and what are their definitions?
Independent Variable, Dependent Variable,
IV, the variable you manipulate, control, or vary in an experimental study to explore its effects
DV, what you measure in the experiment and what is affected during the experiment
Difference between polar and non polar molecules?
Some molecules have positive and negative ends too, and when they do, we call them polar. If they don't, we call them non-polar
What are the proteins main function?
There is no main function the do everything.
What is the scientific definition of Law?
a statement that describes an observable occurrence in nature that appears to always be true
What is the scientific definition of solvent?
A solvent is any substance, usually liquid, which is capable of dissolving one or several substances, thus creating a solution
What is the difference of accuracy and precision.
Accuracy refers to how close a measurement is to the true or accepted value. Precision refers to how close measurements of the same item are to each other
what is the biggest molecule for life and there smallest?
Atom Organism
What do nucleic acids do?
Nucleic acids are large biomolecules that play essential roles in all cells and viruses. A major function of nucleic acids involves the storage and expression of genomic information
What is the scientific definition of principle?
general scientific laws which explain how something happens or works
What is the scientific definition of Hydrophobic?
Something that does not combine with water molecules
Compare and contrast Qualitative and quantitative.
Quantitative data is numbers-based, countable, or measurable. Qualitative data is interpretation-based, descriptive, and relating to language
what are the properties of water that makes it so unique?
It has water tension It has a high specific heat point cohesion adhesion, less dense ads a solid and is a terrific solvent
Compare and contrast Monosaccharide and Polysaccharide?
Monosaccharides are made up with one molecule of glucose while polysaccharides are made up with many molecule of monosaccharides. Monosaccharides are reducing sugars because they reduce copper II to copper I oxide while polysaccharides are non- reducing sugars.
what is the scientific definition of Cell
the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body
what is the scientific definition of Hydrophilic?
Something that will combine with water molecules easily.
Contrast technology and engineering?
technology is the result of applying scientific knowledge and engineering principles to create practical solutions for various purposes, while engineering is the process of designing and constructing specific solutions to address particular challenges.
Compare and contrast atom and a cell?
An atom is a fundamental smallest unit of matter which is made up of protons (positive particles), neutral (neutral particles), and electrons(negative particles). Every matter (solid, gas, liquid, etc.) is made up of atoms. A cell is a fundamental membrane-bound unit of life that can be single-celled or multicellular.
Compare and contrast monomers and polymers?
In chemistry, a monomer is a molecule with low molecular weight that can combine with others of the same kind to form a chemical compound known as a polymer. In other words, polymers are formed from multiple monomers connected together. Mono- means “one” and poly- means “many.” Natural polymers include silk and wool.
What is the scientific definition of Monomer?
Monomers are atoms or small molecules that bond together to form more complex structures such as polymers
What is the scientific definition of surface tension?
The property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of its molecules
