Biology
What are the steps of Mitosis?
interphase, prophase, metaphase, anaphase, telophase, cytokinesis
What Roman Numeral represents a charge of +6?
VI
What is a series circuit?
Components run one after another, two lamps in a row, two batteries in a row
What are the four spheres?
Hydrosphere, Geosphere, Biosphere and Atmosphere
Which process mitosis or meiosis would you use to make new muscle cells after exercise, and why?
Mitosis, because it makes identical cells for growth and repair.
What are the base pairings for DNA?
A-T C-G
How would you balance: Sodium Hydroxide
NaOH
What unit is used to measure electric current?
Amperes (amps).
What is an example of a connection between the Biosphere and Atmosphere?
Answers will vary, but oxygen that animals breathe and then exhale CO2
Why do household circuits use parallel circuits instead of series circuits?
So, devices work independently and still function if one turns off.
Why is mitosis important for healing a cut on your skin?
It produces new, identical cells to replace damaged ones.
2-8-8
A heated blanket creates 125 volts of electricity, but the current caps out around 3 amps, what is the resistance?
41.6 ohms
Why are earthquakes common along plate boundaries?
Because plates collide, slide, or pull apart.
A student claims that meiosis would be better than mitosis for healing a broken bone because it creates more cells. Do you agree or disagree? Explain your reasoning.
Disagree. Mitosis is needed for healing because it creates identical cells with the correct number of chromosomes. Meiosis creates cells with half the chromosomes, which would not function properly in body tissues.
During which phase do sister chromatids separate?
Anaphase.
What is the difference between covalent and ionic bonds?
Ionic transfers electrons from a metal to a non-metal while covalent shares electrons between two non-metals.
Why are short circuits dangerous?
They allow too much current to flow, causing heat and fires.
What causes tectonic plates to move?
Convection currents in the mantle.
When balancing the equation
Al + SO₄ → Al₂(SO₄)₃
why is it important to treat SO₄ as a single unit instead of balancing sulfur and oxygen separately?
Because SO₄ is a polyatomic ion that stays together during reactions. Separating sulfur and oxygen would change the substances involved and make the equation chemically incorrect.
Why does meiosis increase genetic diversity?
Because chromosomes mix and separate differently, creating variation
Balance and name NH4At
Ammonium Astatide NH4At
In which type of circuit do bulbs stay on if one burns out?
Parallel circuit
What is the layer of the atmosphere that contains the Ozone layer?
Stratosphere
Why would meiosis be a disadvantage if it occurred in cells that control electrical signals in the nervous system?
Because meiosis creates genetically different cells with half the chromosomes, which could disrupt normal cell function and interfere with reliable electrical signaling.
