What is a magnet made of, how does it work?
Correct Answer
B. It is made of magnetized iron, it sticks to other magnetic metals.
Explanation
This answer is correct because magnets are typically made of magnetized iron or other materials that have magnetic properties. When a magnet comes into contact with another magnetic material, such as iron or steel, the magnetic forces between the two objects cause them to attract and stick together. This phenomenon is known as magnetic attraction and is the basis for how magnets work.
2.
What keeps us from flying of the earth?
Correct Answer
B. Gravity
Explanation
Gravity is the force that keeps us from flying off the earth. It is the natural phenomenon by which all objects with mass or energy are brought toward one another. The earth's gravity pulls everything towards its center, keeping us grounded and preventing us from floating away. Without gravity, we would not be able to stay on the surface of the earth and everything would float off into space.
3.
What is the definition for energy.
Correct Answer
A. Energy is something that makes things move or work.
Explanation
The correct answer is "Energy is something that makes things move or work." This definition accurately describes energy as the ability to do work or cause a change in motion. It encompasses the concept that energy is what allows objects to move, machines to operate, and processes to occur.
4.
Where do us humans live?
Correct Answer
C. Earth
Explanation
Humans live on Earth, which is the only known planet that supports life. Jupiter and Mars are other planets in our solar system, but they are not suitable for human habitation due to extreme conditions such as lack of breathable atmosphere and extreme temperatures. Planet Zockogumidongo is a fictional planet and does not exist in reality. Therefore, the correct answer is Earth.
5.
What speices of human are we?
Correct Answer
A. Homo-Sapien
Explanation
The correct answer is Homo-Sapien. Homo-Sapien is the scientific name for modern humans. It is the species to which all currently living humans belong. Neanderthals and Homo-Heidelbergensis are extinct species of human ancestors, while "Homo-Faceonlymothercouldlove" is not a valid scientific classification.
6.
Bees communicate by dancing.
Correct Answer
A. True
Explanation
Bees communicate by dancing. This is a well-known fact in the field of entomology. When bees find a food source, they return to the hive and perform a unique dance known as the waggle dance. Through this dance, they convey information about the direction and distance of the food source to other bees in the hive. This form of communication is crucial for the efficient functioning of the colony and is a fascinating example of how animals can communicate complex information without the use of spoken language.
7.
Neanderthals had bigger brains than us Homo-Sapiens.
Correct Answer
A. True
Explanation
Neanderthals had bigger brains than Homo sapiens. This is supported by scientific evidence, including fossil records and studies of Neanderthal skulls. Neanderthals had an average cranial capacity of around 1600 cubic centimeters, compared to the average cranial capacity of modern humans, which is around 1400 cubic centimeters. However, it is important to note that brain size alone does not determine intelligence, as there are other factors such as brain structure and organization that play a role.
8.
How big is a helium atom?
Correct Answer
A. 62 Picometers
Explanation
A helium atom is very small in size, measuring approximately 62 picometers. This is a unit of length used to express atomic sizes, where 1 picometer is equal to 1 trillionth of a meter. The size of an atom is determined by the distance between its nucleus and its outermost electron shell. In the case of a helium atom, it consists of two protons and two neutrons in the nucleus, with two electrons orbiting around it. The overall size is relatively small compared to other atoms, making 62 picometers the correct answer.
9.
What are the 3 "R"s?
Correct Answer
A. Reduce,Reuse,Recycle
Explanation
The correct answer is "Reduce, Reuse, Recycle." These three "R"s are commonly used to promote sustainable practices and environmental conservation. "Reduce" refers to minimizing the amount of waste generated by consuming less and making conscious choices to avoid unnecessary products. "Reuse" encourages the use of items multiple times instead of throwing them away after a single use. "Recycle" involves the process of converting waste materials into new products, thus reducing the need for raw materials and minimizing the impact on the environment.
10.
What are molcules?
Correct Answer
A. The smallest thing that gives a thing it's basic properties.
Explanation
The correct answer is "The smallest thing that gives a thing its basic properties." This explanation accurately describes molecules as the smallest unit of a substance that retains its chemical properties. Molecules are composed of atoms that are bonded together, and they determine the characteristics and behavior of different substances.
11.
What galaxy do we live in?
Correct Answer
A. The Milk Way
Explanation
The correct answer is "The Milky Way." The Milky Way is the galaxy that we live in. It is a barred spiral galaxy that contains our solar system and billions of stars, along with various other celestial objects. The Milked Cow and Andromeda are incorrect options and do not represent the galaxy we live in.
12.
What does RNA stand for?
Correct Answer
A. Ribonucleic Acid
Explanation
RNA stands for Ribonucleic Acid. It is a molecule that is involved in various biological processes, including the synthesis of proteins. RNA is similar to DNA, but it is single-stranded and contains the sugar ribose instead of deoxyribose. It plays a crucial role in gene expression and protein synthesis in cells.
13.
Why are there seasons?
Correct Answer
B. Because the earth is rotating.
Explanation
The correct answer is "Because the earth is rotating." This is because the Earth's rotation on its axis causes different parts of the planet to be exposed to varying amounts of sunlight throughout the year. As the Earth orbits the sun, the tilt of its axis causes the angle and intensity of sunlight to change, resulting in the changing seasons.
14.
What is the water cycle?
Correct Answer
B. The water cycle is the evaporation, condensation and precipitation for clouds.
Explanation
The correct answer is "The water cycle is the evaporation, condensation, and precipitation for clouds." This answer accurately describes the process of the water cycle, which involves water evaporating from bodies of water, condensing into clouds, and then precipitating back down to the earth as rain or other forms of precipitation.
