Life and Scientific Method
Bacteria
Archaea
Eukarya
What are the 3 Domains of Life?
The core theme in Biology. And is the change of populations of species over time.
What is EVOLUTION?
This tells us how many PROTONS an element has on the periodic table.
What is ATOMIC NUMBER?
pH below 7
What is ACIDIC solution?
The 4 classes of BIOMOLECULES
What are Carbohydrates, Proteins, Lipids, and Nucleic Acids?
Contains PROKARYOTIC Cells and are usually UNICELLULAR.
What are
1.) Domain BACTERIA
&
2.) Domain Archaea?
Animals evolve the same trait independently from different ancestors because they live in a similar environment.
What is CONVERGENT Evolution?
These are electrons in the outermost shell of an element/atom that CAN PARTICIPATE in bonds.
What are VALENCE ELECTRONS?
When we put a molecule in a water solution, this happens when water pulls apart the ions in an ionic bond.
What is DISSOCIATING?
These are monomers of PROTEINS.
What are amino acids?
This is a PROPOSED explanation for an observed behavior. And MUST BE TESTABLE.
What is a HYPOTHESIS?
Selective breeding of plants and animals by humans to select for better traits.
What is Artificial Selection?
These bonds have an Electronegativity Difference of 0.4 - 1.8.
What are POLAR COVALENT bonds?
This molecule increases in an acidic solution.
What are HYDROGEN (H+) ions?
These are what links two glucose molecules together to make disaccharide or more to make polysaccharide.
What are GLYCOSIDIC Linkages?
In an experiment, this is MANIPULATED by Researchers.
What is INDEPENDENT Variable?
THE individuals with the BEST TRAITS BEST SUITED for the Environment are more LIKELY TO SURVIVE and Reproduce more offspring and propagate.
What is NATURAL SELECTION.
The tendency of an atom/element to have EIGHT (8) electrons on the most outermost shell.
What is OCTET RULE?
This element is the BACKBONE of all our biomolecules.
What is the Carbon element?
Responsible for maintaining homeostasis by speeding up reactions.
What are ENZYMES?
In an experiment, this is what is MEASURED and used to judge the outcome of the experiment.
What is DEPENDENT Variable?
Animals or different individuals share similar features because they share a common ancestor who had the same trait
What is DIVERGENT EVOLUTION.
A weak bond characterized by a partially positive hydrogen on one molecule and a partially negative atom such as fluorine, oxygen, or nitrogen on another molecule.
What are HYDROGEN BONDS?
Molecules that have the same molecular formula (chemical symbols and subscripts indicating the numbers of atoms in a molecule or compound), but different structures.
What are ISOMERS?
TWO types of ENZYME Inhibition.
What are COMPETITIVE Inhibitors and NON-COMPETITIVE Inhibitors?
