- A.
Robert Hooke
- B.
Greg Mendel
- C.
Dalton
- D.
Rutherford
Correct Answer
B. Greg MendelExplanation
Greg Mendel is known as the "Father of Genetics" because of his groundbreaking work with pea plants. He conducted experiments in the mid-19th century where he crossbred different varieties of pea plants and carefully observed the traits that were passed down to the offspring. Through his experiments, Mendel discovered the basic principles of inheritance, including the concepts of dominant and recessive traits. His work laid the foundation for modern genetics and revolutionized our understanding of how traits are inherited from one generation to the next.Rate this question:

Which scientist concluded that thought the Earth was the center of the solar system instead of the sun?
- A.
Ptomeley
- B.
Bounuelli
- C.
Boyle
- D.
Ohms
Correct Answer
A. PtomeleyExplanation
Ptolemy is the correct answer because he was an ancient Greek astronomer and mathematician who proposed the geocentric model of the universe, which stated that the Earth was the center of the solar system. This model dominated scientific thought for over a thousand years until it was eventually replaced by the heliocentric model proposed by Copernicus.Rate this question:

He was the scientist that was responsible for the principle that when "a body plunged in a fluid, the fluid looses as much weight that is equal to the weight of an equal volume of the fluid" which explains buoyancy.
- A.
Archimedes
- B.
Robert Hooke
- C.
Democritus
- D.
Bounuelli
Correct Answer
A. ArchimedesExplanation
Archimedes is the correct answer because he was the scientist responsible for the principle of buoyancy. This principle states that when a body is submerged in a fluid, it loses weight equal to the weight of the fluid displaced by the body. Archimedes discovered this principle while he was in a bathtub and realized that the water level rose as he got in, demonstrating that his body was displacing an equal volume of water. This principle is fundamental to our understanding of buoyancy and is still used in various applications today.Rate this question:

He was responsible for explaining the principle of "flight" and explained "as the velocity of a fluid increases, its pressure decreases."
- A.
Archimedes(287-212 B.C.)
- B.
Niels Bohr (1885-1962):
- C.
Daniel Bernouilli (1700-82)
- D.
Robert Boyle (1627-91):
Correct Answer
C. Daniel Bernouilli (1700-82)Explanation
Daniel Bernouilli (1700-82) is the correct answer because he was responsible for explaining the principle of flight and the relationship between fluid velocity and pressure. This principle, known as Bernoulli's principle, states that as the velocity of a fluid increases, its pressure decreases. Archimedes, Niels Bohr, and Robert Boyle were not specifically known for their contributions to the principle of flight or this specific relationship between fluid velocity and pressure.Rate this question:

Who was the "father of the cell theory" after he looked at "cork" under a microscope and saw "little rooms" and then called them "cells"?
- A.
Dalton
- B.
Robert Hooke
- C.
Greg Mendel
- D.
Copernicus
Correct Answer
B. Robert HookeExplanation
Robert Hooke is known as the "father of the cell theory" because he was the first to observe and describe cells. When he looked at cork under a microscope, he saw small compartments that he called "cells" due to their resemblance to small rooms. Hooke's observations and naming of cells laid the foundation for the development of the cell theory, which states that all living organisms are composed of cells.Rate this question:

Who was responsible for the organization of the elements in a "periodic table" by atomic number?
- A.
Charles
- B.
Boyle
- C.
Mendeleev
- D.
Democritus
Correct Answer
C. MendeleevExplanation
Mendeleev was responsible for the organization of the elements in a "periodic table" by atomic number. He is credited with creating the first widely recognized periodic table, which arranged the elements in order of increasing atomic mass. However, he also left gaps in the table for undiscovered elements and predicted their properties based on the patterns he observed. His periodic table laid the foundation for the modern periodic table that we use today, which is organized by atomic number rather than atomic mass.Rate this question:

Pascal
Correct Answer
B. DaltonExplanation
Dalton is considered the "Father of Atomic Theory" because he proposed the first modern atomic theory in the early 19th century. His theory stated that all matter is made up of tiny indivisible particles called atoms, which combine to form compounds in fixed ratios. Dalton's theory also introduced the concept of conservation of mass in chemical reactions and provided a framework for understanding the behavior of gases. His work laid the foundation for the development of modern chemistry and our understanding of the structure and properties of matter.Rate this question:

Boyle
Correct Answer
B. LlnnaeusExplanation

- D.
Galileo
Correct Answer
A. DemocritusExplanation
Democritus is credited with the discovery of the "atomos" and the idea that it is indivisible. He proposed that all matter is made up of tiny, indivisible particles called atoms. This theory challenged the prevailing belief at the time that matter could be infinitely divided. Democritus' ideas laid the foundation for modern atomic theory and greatly influenced the development of scientific thought.Rate this question:

Who discovered that "resistance equals voltage, divided by current"?
- A.
Mendeleev
- B.
Ohms
- C.
Rutherford
- D.
Thomson
Correct Answer
B. OhmsExplanation
Ohms discovered that "resistance equals voltage, divided by current." He formulated Ohm's law, which states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to the resistance of the conductor. This fundamental relationship between voltage, current, and resistance is widely used in electrical and electronic circuits.Rate this question:

Whose model of the atom looked like the "blueberry muffin" or "plum pudding model" to represent the electrons and protons in it?
- A.
Rutherford
- B.
Dalton
- C.
Thomson
- D.
Mendel
Correct Answer
C. ThomsonExplanation
Thomson's model of the atom, also known as the "plum pudding model" or "blueberry muffin model," proposed that the atom is a positively charged sphere with negatively charged electrons embedded within it, similar to the way plums or blueberries are embedded in a muffin or pudding. This model suggested that the atom is mostly made up of positive charge with small negatively charged electrons scattered throughout. This model was later disproven by Rutherford's gold foil experiment, which led to the discovery of the atomic nucleus.Rate this question:
