A scientist changes the amount of fertilizer given to plants and measures plant height after four weeks. What is the independent variable?
Amount of Fertilizer

Describe the density of ice vs water
Ice is less dense than water (volume decreases as mass stays the same) -> floats

What is the monomer of a carbohydrate?
monosaccharide

What elements make up proteins?
C, H, O, N and sometimes S

A researcher investigates whether temperature affects the growth of sunflowers. One group is kept at 10*C (cold temperatures), while another is kept at 40*C (hot temperatures). A control group is the sunflower grown at 25*C (the ideal condition for sunflower growth). All other conditions are kept identical. Identify this specific control group.
Positive Control

Provide a general name for the molecules above and the polarity.
hydrocarbons
nonpolar

Classify glycogen and provide its function.
polysaccharide
found in animals
regulates blood glucose levels by being stored in the liver and muscle cells

If you had a DNA molecule that had the following sequence: 5' ATCATTG 3' what would be the complementary strand?
3' TAGTAAC 5'

What describes a number that shows how far apart the numbers are from their average (mean)
standard deviation

What would be the functional group that is found in all alcohols?
-OH (hydroxyl)

Describe the two parts of a phospholipid (use three descriptive terms for each part)
phosphate head - hydrophilic - polar
fatty acid tails - hydrophobic - nonpolar
300
What level of protein structure will form disulfide bridges? Between what amino acid?
Tertiary - Cysteine

Why do we use ± 2 SEM?
When creating a bar graph how do we know that the data is statistically significant?
to ensure a 95% condifence interval
The error bars DO NOT OVERLAP

Given that sucrose is made up of glucose and fructose. Describe how dehydration synthesis and hydrolysis would work to break down and build these molecules.
Sucrose -> glucose + fructose (add water to break the bond - hydrolysis)
glucose + fructose -> (remove water to form bond - dehydration synthesis)

Classify cholestrol, provide its generalized structure, and provide its key function for the plasma membrane.
steroid (lipid) - four carbon fused rings - maintain fluidity - prevents the phospholipids from spreading too far apart or constricting too close together
400
What form of protein structure is pictured above.
Label each one.
Which form involves hydrogen bonding between every 4th amino acid?
Secondary
Left - beta pleated sheet; right - alpha helix
Alpha helix - forms hydrogen bonding

Scenario: An AP Biology student tests whether varying the concentration of sucrose solution (0.0M, 0.2M, 0.4M, 0.6M, 0.8M, 1.0M) affects the percent mass change of core potato samples. [1, 2]
Research Question: Does the concentration of the surrounding sucrose solution affect the percent change in mass of potato cores?
Create a null hypothesis
The concentration of sucrose solution does not affect the percent change in mass of potato cores.

Describe how sweating cools a person down.
Evaporative cooling - individuals will sweat - as water leaves the body it takes heat with it.

Differentiate between the structure of starch and cellulose
Starch has alpha hydroxyl groups while cellulose has alternative alpha and beta hydroxyl groups.
This results in starch becoming a branched molecule, while cellulose is linear and stacked.

Which bond connects a phosphate group to the pentose sugar found in DNA or RNA
phosphodiester bond (type of covalent bond)
