1. Three of what sub-atomic particles make up a proton?

Neutrons

Electrons

Quarks

Atoms

Protons are made up of three quarks. Quarks are elementary particles that are considered to be the building blocks of matter. They come in different types, or flavors, such as up, down, charm, strange, top, and bottom. Protons consist of two up quarks and one down quark, which gives them a positive charge. Neutrons, on the other hand, are made up of three quarks as well, but they consist of two down quarks and one up quark, resulting in no charge. Electrons are not sub-atomic particles that make up a proton, but they are negatively charged particles that orbit around the nucleus of an atom. Atoms, on the other hand, are made up of protons, neutrons, and electrons, but they are not sub-atomic particles themselves.

2. Pluto has recently been changed from a ______ to a ________, more commonly called dwarf planet.

Planet; star

Planet; asteroid

Planet; trans-neptunian object

Star; planet

Pluto has recently been changed from a planet to a trans-neptunian object, more commonly called a dwarf planet. This change occurred because the International Astronomical Union redefined the criteria for what qualifies as a planet, and Pluto no longer met those criteria. Instead, it was categorized as a trans-neptunian object, a term that refers to objects that orbit the Sun beyond Neptune's orbit. This reclassification was made to better understand and categorize the various celestial bodies in our solar system.

3. Deoxyribonucleic acid (DNA) is made up of _____ nitrogen bases.

Four

Three

Two

Six

They are Adenine, Thymine, Guanine, and Cytosine.

Explanation

They are Adenine, Thymine, Guanine, and Cytosine.

4. Oxygen was discovered in 1774 by who?

Joseph McGrannahan

Robert Barone

Joseph Priestley

Augustin von Uukskafrusken

Joseph Priestley is the correct answer because he is credited with the discovery of oxygen in 1774. Priestley was an English chemist and theologian who conducted experiments on gases, including the discovery of oxygen gas. His work laid the foundation for the understanding of oxygen's role in combustion and respiration, and he is considered one of the pioneers of modern chemistry.

5. What is the largest biome on Earth (not counting Ocean)? Hint: It is found south of the tundra.

Taiga

Desert

Tropical rain forest

Grassland

The taiga is the largest biome on Earth, excluding the ocean. It is found south of the tundra and is characterized by its cold climate and extensive forests of coniferous trees. The taiga covers vast areas of North America, Europe, and Asia, making it the largest terrestrial biome. It is home to a diverse range of plant and animal species, including bears, wolves, and moose. The taiga's size and unique ecosystem make it the correct answer to the question.
