A lens that curves inwards.
What is a concave lens?
The average weather in an area over a long period of time.
What is climate?
What is the formula to calculate the index of refraction? Provide a description of each variable.
n = c/v
How do scientists know what Earth's climate was like thousands of years ago?
Ice cores, Tree Rings/Coral Reefs, and Rock/Ocean Sediment/Caves
A description of the osmosis process. What are the 3 types of osmosis states?
The process in which the solvent moves through a semipermeable membrane from a dilute solution into a more concentrated solution.
Hypotonic
Hypoertonic
Isotonic
What are the SALT characteristics for a convex mirror?
A - upright
L - behind mirror
T - virtual image
Describe the molecular difference between a acid and a base. Provide an example of each (formula and name).
Acid - lower pH (0-7) and has a higher concentration of H+ ions
Base - high pH (7-14) and has a lower concentration of H+ ions
Acid - H2SO4 - sulfuric acid or HF - hydrofluoric acid
Base - NaOH - Sodium Hydroxide - CO3 carbonate of some sort
What are the two chemical compounds from your summative that are responsible for trapping heat in the atmosphere.
SO2 & NOx
Using the "Mitosis Hand Model", describe the stages of Mitosis in order. How many chromosomes should a organism with 2n = 8 have at the end of mitosis?
Metaphase - chromosomes aligning in the middle
Anaphase - sister chromatids being pulled to opposite ends
Telophase - the reforming of nuclear membrane and coiling of chromosomes
The organism should have 8 chromosomes in each daughter cell.
What is refraction? What type of lens is this?
Describe the "Greenhouse Gas Effect".
The Greenhouse Gas Effect serves as a blanket that traps the heat from leaving Earth. There are certain chemical compounds such as CO2 and NOx and SO2 that help to trap the heat. Due to an increase in human activity, the greenhouse gases are becoming more and more abundant in the atmosphere, which is becoming more dangerous.
