Motion
Inertia, which Newton describes in his first law, says objects in motion remain in motion, and objects at rest remain at this.
What is rest?
Calcium has atomic number 20, which means the ion Ca2+ has this many electrons.
What is 18?
The lithosphere, which is composed of tectonic plates that float on top of the aesthenosphere, consists of the Earth's crust, and the upper part of this layer of the Earth.
What is the mantle?
This kind of mixture may appear homogeneous from a distance, but at the molecular level, different parts of it are made of different chemical compounds.
What is heterogenous?
If you think of a recipe as a gene, then different versions of the recipe - say one calls for white sugar and the other calls for brown sugar - would be called this.
If one car is driving 60 mph North, and one car is driving 60 mph East, the two cars have the same speed, but different this.
What are velocities?
What two atoms have a covalent bond, they share one of these.
What is an electron?
What are minerals?
Salt mixes with water to form this type of homogenous mixture, where each salt molecule breaks apart into two ions, surrounded by water molecules.
What is a solution?
If you get a dominant allele of a gene from your father and the recessive allele from your mother, and your sister gets the recessive allele from you father and the dominant one from your mother, you and your sister have the same this.
What is a genotype?
What is a force?
H+ ions, created when you dissolve an acid in water, are also knows as this type of particle.
What is a proton?
The branch of Earth Science that studies oceans.
What is meteorology?
When water vapor in the sky turns directly into ice crystals to form clouds, it's an example of this, the opposite of sublimation.
What is deposition?
Two identical twins have the same genotypes for every trait, but still may end up different due to this.
What are environmental effects?
Meters per seconds squared is the SI unit for this.
What is acceleration?
If you combine an acid and a base, you get this.
What is a salt?
It should like they study meteors, but this type of science actually studies weather.
What is a meteorologist?
Neutron stars, the densest objects in the universe after black holes, are made entirely of this electrically neutral fundamental particle.
What are neutrons?
According to Mendelian genetics, if both of your grandfathers have blue eyes, a recessive trait, but both of your parents have brown eyes, a dominant trait, this it the probability that you will have blue eyes.
According to Newtons third law, if you apply 10 Newtons of force to an object, it will apply this many Newtons of force to you, in the opposite direction.
What is 10?
A solution with a ph level of 13, would be a strong type of this.
What is a base?
Studying the effects of humans on climate change would be an example of this type of science, which studies the way humans interact with their environment.
What is environmental science?
An element is made of only one type of atom, while a chemical compound can be made of several kinds of atoms, but only one type of this.
What is a molecule?
For the alleles H and h, HH and hh are examples of this type of genotype.
What is homozygous?
