Isotopes are variant forms of an element; Radioactive isotopes are what?
What is when the nucleus decays spontaneously, gives off particles and energy.
What molecule is most widely known to be THE organic molecule?
Carbon
The core theme that makes sense of all biology is...
What is evolution.
What are the 3 Domains and 3 Kingdoms of life?
What is Archaea, Bacteria, and Eukarya; What is Animalia, Fungi, Plantae.
12 inches is ? cm.
What 3 things does an atom consist of? What is its new name if there are two or more atoms bonded together?
What are protons, neutrons, and electrons; molecule.
What are the 4 macromolecules and their matching monomers and polymers?
Carbohydrates; Monosaccharide; Polysaccharide
Lipids; Fatty acids and glycerol; Phospholipid (and some others like glycolipids)
Protein; Amino acids; Polypeptide
Nucleic acid; Nucleotide
This theory proposes that species change over time through a process where individuals with beneficial traits are more likely to survive and reproduce, then pass those traits onto their offspring.
What is the Darwin-Wallace theory of evolution.
What is a Virus and what are the two types?
What is a microscopic organism that can only survive by infecting a host. Two types are Lytic and Lysogenic.
You have two kids, one has a temperature of 100 degrees F and the other has a temperature of 40 degrees C. Who has the higher fever?
What is Kid 2, the one with a temperature of 40 degrees C.
Carbon has an atomic number of 6. Based on its electron configuration, how many electrons are in the first and second shells? What is the outermost shell typically called?
What is 2 in first shell and 4 in the second shell; Valance.
Which process involves the addition of water to break down macromolecules into monomers? What is the primary role of dehydration synthesis in the body?
What is hydrolysis; Building macromolecules by forming bonds between monomers.
True or False. According to the Darwin-Wallace theory of evolution by natural selection, all members of a population are equal in regard to their ability to survive and produce offspring; survival is solely based on chance.
What is false.
What is Homeostasis?
An adult lab weighs 18.15 kg, what is his weight in grams?
What is 18,150 g.
A radioactive isotope of carbon had an atomic number of 6 and a mass of 14. How many neutrons does this isotope have? What is the equation to figure this out?
What is 8 Neutrons.
Atomic Mass - Atomic # = # for Neutrons
What are the main short term energy storage molecules for humans (and animals) and what is the main short term energy storage molecule for plants?
What is glycogen and starch.
What are some examples of natural selection?
Giraffes: Developed longer neck to reach leaves others cant.
Galapagos finch bird: Beak changed over generations to be able to pick up food better; long strong beaks were good for cracking nutsp; small and pointy for getting insects.
Peppered Moths: Changed light color to dark to blend in with trees better, they needed to change because of pollution and they weren't camouflage anymore.
Antibiotic resistance in bacteria
Pesticide resistance in insects
What are 7 of the properties of life?
What is order, regulation, evolutionary adaptation, stimulus/response to environment/stimuli, energy processing, growth and development, and reproduction.
Going larger in size (Deci to Kilo) means you move the decimal point to the ___. Going smaller (Deci to Milli) means you move the decimal point to the _____.
What is left, right.
Compounds, such as water, have electrons that are shared unequally between the atoms and this causes one end to be slightly negative and the other to be slightly positive. What is this bond? If it was shared equally then what kind would it be?
What is the structure of the 4 big macromolecules? (don't forget about the 2 kinds of lipids...)
Carbohydrates: Composed of carbon, hydrogen, and oxygen; simple sugars
Lipids: Made mostly of carbon and hydrogen atoms; unsaturated VS saturated; Unsaturated: missing hydrogen, double bonded, and liquid at room temp.; Saturated: Hydrogen chains, single bonds, and solid at room temp.
Protein: Amino acids linked by peptide bonds; 4 complex structures: Primary, secondary, tertiary, and quaternary.
Nucleic Acids: Are built with a sugar, phosphate group, and nitrogenous base. 2 examples: DNA and RNA.
What are two examples of evidence for evolution?
What is homologous structures (bone developments), fossil records, Vestigial organs (tail bone), direct observation, or Darwin/Wallace's contributions.
