Cells and Organelles
The control center of the cell responsible for sending out RNA.
What is the nucleus?
An element with the smallest molar mass, being composed of only one proton.
What is hydrogen?
A term used to describe the result returned when a number is multiplied by itself.
This part of the atom holds a small, negative charge.
What is an electron?
This type of lens resembles an hourglass shape and reflects incoming rays of light outwards.
What is a convex lens?
This organelle is responsible for cellular respiration, which is when food is turned into energy.
What is mitochondria?
A family of extremely reactive elements, such as lithium, sodium, and potassium.
What are alkali metals?
On a coordinate plane, this term is used to define the point (0, 0).
A type of circuit in which the electrons create excess energy due to the energy not being released in the form of an output device.
What is a short circuit?
The part of the human eye that controls how much light enters.
What is the iris?
Bacteria are an example of this type of cell, which don't have membrane-bound organelles.
What is a prokaryotic cell?
A term used to describe elements that are covalently bonded to themselves, such as Oxygen, Iodine, and Chlorine.
What are diatomics?
A cylinder has a radius of 5cm and is able to perfectly fit 4 tennis balls with a radius of 5cm. To the nearest whole cubic centimetre, this is the volume of the cylinder.
What is 1571 cm3?
A material, such as rubber, that prevents electrons from flowing through easily.
What is an insulator?
A term used to describe an object that transmits light, but scatters it in the process, creating a blurry filter-like image.
What is translucent?
Besides the chloroplast, this organelle is only found in plant cells, and not animal cells.
What is a cell wall?
The Russian chemist generally acknowledged as the "father" of the modern periodic table.
Who is Dmitri Mendeleev?
A right triangle has a hypotenuse of 18cm and one angle of 31o. To the nearest hundredth of a centimetre, this is the length of the shortest side of this triangle.
What is 9.27 cm?
A circuit with a 6Ω resistor, a 11Ω resistor, and a 23Ω resistor connected in series, hooked up to a 10V battery has this much current flowing through it.
What is 0.25A?
A term used to describe the first light ray that hits a mirror.
What is the incidence ray?
This organelle contains digestive enzymes that are used to break down waste and other items the cell no longer needs.
What is a lysosome?
The element on the periodic table with the highest melting point.
What is tungsten?
A term used to describe numbers that are "counted." This includes all whole numbers beginning with 1 but excluding 0.
What are natural numbers?
A circuit has two 5Ω lightbulbs connected in parallel, a 15Ω fan connected in series with the two lightbulbs, and a 20Ω resistor connected in parallel with the above contraption. A voltage drop of 5V is measured across the battery. This much current, to the nearest tenth, is flowing through the resistor.
What is 46.7A?
The middle layer of the eye, located between the sclera and the retina.
What is the choroid?
