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.'"

Periodic Table Trends

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.
