    Study Notes

    Percentage Change in Price

    • A television's price fell from $450 to $400, indicating a change of $50.
    • To calculate percentage change: (change in price / initial price) × 100 = (-11%).

    Types of Natural Lipids

    • Supersaturated is not a natural lipid; the other types include saturated, unsaturated, and polyunsaturated lipids.
    • Unsaturated and polyunsaturated lipids feature double bonds in fatty acid chains.

    Mitosis Facts

    • Mitosis produces identical daughter cells; thus, daughter cells are not different from parent cells.
    • The process consists of four phases: prophase, metaphase, anaphase, and telophase.

    Golgi Apparatus Function

    • The Golgi apparatus transports materials within eukaryotic cells.
    • Other organelles handle digestion (lysosomes), food uptake (vacuoles), and respiration (mitochondria).

    Chemical Combustion

    • Combustion occurs when hydrocarbons are heated, producing carbon dioxide and water.

    Double Covalent Bonds

    • A double covalent bond forms when two electron pairs are shared between atoms.

    Suffix Usage

    • The suffix -oid indicates resemblance (e.g., tabloid, spheroid).

    Atom Composition

    • Atoms consist of protons, neutrons, and electrons; isotopes are variants with differing neutron counts.

    Skeletal System

    • Cartilage belongs to the skeletal system, which supports movement, protection, and metabolism.

    Phases of Matter

    • Solids have molecules that exert strong attraction and move slowly compared to liquids and gases.

    Adrenocorticotropic Hormone (ACTH)

    • ACTH stimulates cortisol production; it is an important hormone in stress response.

    Metric System Weight

    • The gram is the basic weight measure in the metric system.

    Identifying Pronouns

    • Pronouns replace nouns; “He” is a pronoun in the sentence provided.

    Endogenous Definition

    • "Endogenous" means produced within the body, as in the case of insulin.

    Supporting Detail Indicators

    • Transition words typically indicate supporting details in writing.

    Subject-Verb Agreement

    • The sentence "The students was driving..." is incorrect; it should use "were."

    Kidney Stones Formation

    • Oxalates can contribute to calcium kidney stone formation.

    Ribosome Function

    • Ribosomes use RNA to synthesize proteins.

    Volume Calculation

    • 432 cubic inches is 25% of a cubic foot.

    Role of Catalysts

    • Catalysts increase the reaction rate without undergoing chemical change.

    Glycolysis Products

    • Glycolysis produces two ATP, two pyruvate, and two NADH molecules.

    Melting Point Definition

    • The melting point is the temperature at which a solid becomes a liquid.

    Septum in the Heart

    • The septum divides the right/left ventricles from the right/left atria.

    Meiosis Outcome

    • Each daughter cell from meiosis contains 23 chromosomes.

    Mitosis Overview

    • Mitosis consists of four stages: prophase, metaphase, anaphase, and telophase.

    Charge Calculation

    • A 3- charged atom of element X reacting with two 1+ charged Y atoms results in a final charge of 1-.

    Epistasis in Genetics

    • Epistasis involves one gene's effect being dependent on one or more modifier genes.

    Water Leakage Calculation

    • After two days, a tank will contain 79,680 cubic inches of water after leakage.

    Fraction Conversion

    • The decimal 1.05 can be expressed as the fraction 21/20.

    Additional Pronouns

    • In the sentence “I asked him…”, "him" is a pronoun.

    Liver Disease Cause

    • Alcohol abuse is commonly associated with liver disease.

    Recessive Allele Representation

    • Recessive alleles are represented by lowercase letters in Punnett squares.

    Temperature Effect on Reaction Rate

    • Increasing temperature enhances the reaction rate by increasing molecular movement.

    Atomic Number Definition

    • The atomic number of an atom is equal to the number of protons; here, it is 45.### Hydrogen Bonds
    • Hydrogen bonds form when a hydrogen atom is attracted to highly electronegative elements.
    • This type of bond is classified as an intermolecular force.

    Steroids

    • Steroids are a type of lipid that acts as membrane components.
    • They serve as precursors for significant hormones.
    • Lipids also encompass fatty acids and phospholipids, commonly referred to as fats.

    Mitosis: Anaphase

    • Anaphase marks the stage in mitosis when chromosomes begin to separate.

    Subjective Writing

    • Subjective writing reflects personal feelings, attitudes, and opinions.

    Punctuation: Colons

    • A colon (:) is used to introduce quotations, sentences, or questions formally.
    • Example usage: "Darla stated: 'I am the only individual who has achieved perfection.'"
    • As one moves from left to right across the periodic table, the atomic radius decreases.
    • This decrease occurs due to the increased number of protons, enhancing attraction forces drawing electrons closer to the nucleus.

    Prepositions

    • "Under" is identified as a preposition in the sentence about finding a stuffed animal.
    • Prepositions establish relationships between objects and other words in a sentence.

    Sentence Construction

    • The sentence "I must have got some sun from working outside all day" is classified as a simple sentence.
    • It consists of one independent clause and contains two phrases, lacking dependent clauses.

    Emulsions

    • Emulsions are solutions that readily combine separate matter, such as water and oil.
    • They differ from compounds, which create a single matter by mixing elements, and alloys, which form new types of metals.
    • Amalgams involve mercury to dissolve other metals.
