The SAT and ACT both test your precision of language. – No commas around a name – Watch for singular/plural issues (singular–it and plural–they) – No comma between subject and verb – The company made. no commas here – Check to make sure you have a full sentence – 3/4 ways to separate 2 full[…]
Definitions for Chemistry Labs: – Solution = liquid mixture – Titrant = solution of a known concentration. Use a burette to put the titrant into a solution (in a beaker). – Solute = minor component that is uniformly distributed in the solvent – Solvent = major component that contains the solute – Precipitate = insoluble[…]
CH4 + 2O2 –> CO2 + 2H2O Left hand side: 1 C, 4 H, 4 O Right hand side: 1 C, 4 H, 4 O
These equations are important for SAT and ACT math. – Percent change: (new-old)/old * 100 – Percent error: (experimental-theoretical)/theoretical *. 100
– Density = mass/volume – Increasing pressure always raises density. Increasing temperature usually lowers density. When water freezes, it is less dense than liquid water. – Force of a spring = kx k is a constant and x is the amount of stretch or compression. – PE(spring) = 0.5kx^2 – Fahrenheit and Celsius F =[…]
– D=RT distance = rate * time – Position is in meters – Velocity is change in position, in meters per second – Acceleration is change in velocity, in meters per seconds^2 – Relative probability: P(X|Y) = P(X and Y) / P(Y) = probability of X given Y
Cellular Respiration: – Occurs in mitochondria – Plants and animals – Converts chemical energy (glucose) to ATP – Solar energy –> photosynthesis—chemical energy –> cellular respiration—ATP – Cell membrane – used for active and passive transport
It is important to know basic biology, chemistry, and physics for the ACT Science section! – Facilitated diffusion = molecules go from an area of higher concentration to lower concentration with the help of a carrier molecule – across a selectively permeable membrane – can be with larger molecules – Ribosomes = protein builders of[…]
Monocot = flowering plant whose seeds have one embryonic leaf (cotyledon) Dicot = plant with seed with two embryonic leaves (cotyledons)
What is mitosis? Mitosis is the process of cell division. One cell becomes two cells with full chromosomal identity. Stages of mitosis: 1. Prophase 2. Metaphase 3. Anaphase 4. Telephase Cytokinesis begins in anaphase or telephase. Cytokinesis is the division of the cytoplasm into 2 new cells.
