Life Finds A Way
This organelle is often called the "powerhouse of the cell" because it produces most of a cell's ATP.
What is a Mitochondrion?
This particle has a positive electrical charge and is found in an atom's nucleus.
What is a proton?
This force opposes motion when two surfaces rub against each other.
What is friction?
Organisms that make their own food, usually using sunlight, are called this.
What are producers?
This planet is the largest planet in our solar system.
What is Jupiter?
This organ filters waste from the blood and produces urine.
What is the kidney?
During photosynthesis, plants take in this gas and liquid from the atmosphere and environment to survive.
When a solid changes directly into a gas without becoming a liquid first, this process occurs.
What is sublimation?
An object traveling at a constant velocity has this value for its acceleration.
What is zero?
This greenhouse gas is released when fossil fuels such as coal, oil, and natural gas are burned.
What is carbon dioxide?
The apparent yearly path of the Sun across the sky is called this.
What is the ecliptic?
This muscle contracts and relaxes to help move air into and out of the lungs.
What is the diaphragm?
This process produces two genetically identical daughter cells from one parent cell.
What is mitosis?
An atom of an element that has gained or lost electrons is called this.
What is an ion?
This quantity describes both how much matter an object contains and how difficult it is to accelerate.
What is mass?
When a species disappears completely from Earth, it has undergone this.
What is extinction?
A star's color can tell astronomers about its surface temperature. Of these colors, blue or red, which generally indicates a hotter star?
What is blue?
Red blood cells contain this protein, which binds to oxygen and gives blood much of its red color.
What is hemoglobin?
This term describes a person with two different versions of a gene for a particular trait (For example, Aa).
What is heterozygous?
This type of chemical bond forms when atoms share electrons.
What is a covalent bond?
When a wave bends as it passes from one medium into another because its speed changes, this occurs.
What is refraction?
In a food chain, only a small percentage of energy is typically transferred from one trophic level to the next. Most of the energy is lost primarily as this.
What is heat?
This is the stage of a Sun-like star's life when it expands dramatically after exhausting the hydrogen in its core.
What is a red giant?
When you suddenly become frightened, your heart rate increases, your pupils widen, and your breathing speeds up. Which division of the nervous system is primarily responsible for this response?
What is the sympathetic nervous system?
This molecule carries instructions from DNA to the ribosomes, where proteins are made.
What is messenger RNA (mRNA)?
If a solution has a pH of 2 and another has a pH of 4, the first solution has this many times the hydrogen-ion concentration of the second.
What is 100 times?
A 2-kilogram object accelerates at 3 m/s². According to Newton's second law, what net force acts on it?
What is 6 newtons?
DOUBLE JEOPARDY: When fertilizer runoff adds excess nitrogen and phosphorus to a lake, causing algae to grow rapidly and oxygen levels to fall, this process occurs.
What is eutrophication?
Scientists use this effect—the change in the observed wavelength of light caused by an object's motion—to determine whether distant galaxies are moving toward or away from us.
What is the Doppler effect?
This hormone lowers blood glucose levels by helping cells take glucose out of the bloodstream.
What is insulin?
A mutation changes a DNA codon from GAA to GAG, but the resulting protein functions normally. What type of mutation is this?
What is a silent mutation?
An atom has 17 protons, 18 electrons, and 18 neutrons. What is the element and what is its overall electrical charge?
What is chlorine with a −1 charge (Cl⁻)?
A car's velocity changes from 10 m/s to 30 m/s in 5 seconds. Assuming constant acceleration, what is its acceleration?
What is 4 m/s²?
A population of insects is exposed to a pesticide. Most insects die, but a few survive because they have a genetic trait that makes them resistant. After many generations, most of the population is resistant. What process caused this change?
What is natural selection?
A star has a much greater mass than the Sun. After exhausting the nuclear fuel in its core, it eventually explodes as a supernova. What extremely dense object could remain after the explosion if the star's core is massive enough?
What is a black hole?
A person suffers damage to the cerebellum. Which major function would most likely be affected?
What is coordination of movement and balance?
