Chapter 1&2, & Labs
Both a body of knowledge (data) about the world and an evidence-based process for acquiring that knowledge.
What is science?
The substance that undergoes a chemical change.
Reactants
The part of the cell that contains chromosomes made of protein and DNA.
What is the nucleus?
Asexual reproduction in eukaryotic cells.
What is mitosis?
A small region of the DNA on a chromosome coding for a genetic trait.
What is a gene?
The metric units for mass.
What are grams?
They are not polymers, but they are made up of hydrocarbons, fatty acids, and/or glycerol.
What are lipids?
A word used to describe an animal cell when it is put into a solution that is isotonic to the cell's interior?
The phase of mitosis in which the replicated chromosomes condense and attach to the mitotic spindle, and the nuclear envelope breaks down.
What is prophase?
The phenotype of the offspring when a true bred purple plant fertilizes a true-bred white plant. (Purple is dominant.)
What is purple?
Scientific-sounding statements, beliefs, or practices that are not based on the scientific method.
What is pseudoscience?
The type of bonds that connect all the carbon atoms in carbohydrates.
covalent
Evidence for this theory includes common DNA structure, cell shape & size, and double membrane in all living things.
What is endosymbiotic theory?
A synthetic chemical found in plastics that mimics estrogen and has been found to disrupt the process of meiosis in mice, causing problems such as cancer and birth defects.
What is BPA?
Color-blindness, albinism, and sickle cell disease are examples of this, because they are controlled by a single gene, and unaffected by environmental conditions.
What are Mendelian traits?
On a microscope, the measure of image clarity.
What is resolving power?
The first of the 4 levels of protein structure.
The three things that a plant cell has but an animal cell doesn't have.
What are a large central vacuole, chloroplasts, and a cell wall.
What is a homologous pair?
The organisms involved in the first cross.
What is the p generation?
What is crossing over?
The number of times more basic a solution of pH 10 is compared to a solution of pH 8.
What is 100 times?
In some organisms, this process is a way of eating. In others, it happens when white blood cells remove bacteria and cell debris from the blood, by forming a pseudopodium from the plasma membrane.
What is phagocytosis?
This process describes something that happens in metaphase I, when each homologous chromosome pair orients itself at the metaphase plate. They don't always line up the same way, which is one reason why the daughter cells come out different at the end.
What is independent assortment?
A species of monkey has either 4 fingers or 5 fingers. 4 fingers is dominant. What is the ratio of 4-fingered to 5-fingered offspring in a cross between a monkey that is heterozygous for this trait and a monkey that has 5 fingers?
What is 1:1?
