Biology is defined as
What is the study of organisms?
Mass is defined as
what is a measure of quantity of matter present
Macromolecules are defined as
what is polymers containing thousands or ore atoms
What is the differnce between Eukaryotic cells and prokaryotic cells?
Eukaryotic cells are cells containing membrane-bound organelles and are the basis for both unicellular and multicellular organisms. In contrast, prokaryotic cells do not have any membrane-bound organelles and are always part of unicellular organisms
What is photosythesis?
what is a process in which sunlight is transformed into a form of chemical energy that can be used for work?
Nucleus is defined as
What is the organelle that contains the cells genetic information.
Valence shell is defined as
what is the outermost dhell that can host up to 8 electrons
Monosaccharides is defined as
what is simple sugars
Four kinds of macromolecules
what is carbohydrates, proteins, nucleic acids and lipids
Amino Acids have...
what is a carboxyl functional group and an amino functional group
Comaparative Experiments is defined as
What is data gathered from different populations that differ in multiple ways?
Isotopes are define as
what is elements that have the same number of protons but different number of neutrons
Polypetide Chains is defined as
what is unbranded polymers of covalently bonded amino acids
What are the three major categories of life?
What is bacteria, Archaea, and Eukarya
When salt solution evaportates (chemical and phsyical level)
What is at a chemical level, evaporation eliminates water for hydration of the ions, so the ions are no longer separated. At the physical level, the salt will no longer dissolve in and crystals will form.
Nucleic Acid is defined as
What is a polymer made up of nucleotides specialized for the storage, transmission and expression of genetic information. Example: DNA and RNA are nucleic acids.
Radioisotopes is defined as
what is unstable isotopes that spontaneously give off energy in the form of alpha, beta, and gamma particles
Glycosidic bonds
what is bonds between disaccharides, oligosaccharides, and polysaccharides
The difference between Inductive Logic and Deductive Logic
What is inductive involves taking observations or facts to formulate a new proposition while deductive logic starts with a hypothesis and then goes to predict what facts would have to be true to be compatible with the statement
Disulfide bridges determine
what is how a polypetide chain will fold
Aerobic Metabolism is defined as
What is a biochemical process that uses 02 to extract energy from nutrient molecuels
The trend and definition of Electronegativity
what is the attractive force that an atomic nucleus exerts on electrons, it increases from left to right and bottom to top across the periodic table
Oligopeptide is defined as
what is short polymers of 20 or fewer amino acids
what is cellulose
Atoms like Na (sodium) form ionic bonds opposed to covalent bonds
what is because it is a metal that "wants" to give away electrons versus being a nonmetal
