Science is the broad field that is concerned with phenomena in nature. Additionally, it engages experiments that give rise to useful postulations. These are further tested to make reasonable inferences as numbers or laws. Certain laws namely; Newton's law, Faraday principle among others; were confirmed through scientific methods. How much do you know about science?

Questions and Answers

1.

Which of these is not a major division of science?
- A.
  
  Formal science
- B.
  
  Natural science
- C.
  
  Space science
- D.
  
  Social science
Correct Answer
C. Space science

Explanation
Space science is not a major division of science because it is a subfield of natural science. Natural science encompasses the study of the physical world, including physics, chemistry, biology, and earth science. Space science specifically focuses on the study of celestial objects, such as planets, stars, and galaxies, as well as the phenomena that occur in outer space. While space science is an important and specialized field, it is considered a subset of natural science rather than a major division in its own right.

Which of these scientists was not involved in Antiquity?
- A.
  
  Erasthosnes
- B.
  
  Euclid
- C.
  
  Hipparchus
- D.
  
  Theophrastus
Correct Answer
A. Erasthosnes

Explanation
Erasthosnes was not involved in Antiquity. Although he was a prominent Greek mathematician, geographer, and astronomer, he lived during the Hellenistic period, which came after the end of Antiquity. Antiquity refers to the period of ancient history that encompasses the civilizations of Greece and Rome, from around the 8th century BCE to the 6th century CE. Therefore, Erasthosnes cannot be considered a scientist involved in Antiquity.

Who described the origin of species?
- A.
  
  Jose Rogers
- B.
  
  Edwin Bob
- C.
  
  Charles Darwin
- D.
  
  Jean Lamarck
Correct Answer
A. Jose Rogers
4.

What science is concerned with the composition and decomposition of matter?
- A.
  
  Chemistry
- B.
  
  Astronomy
- C.
  
  Physics
- D.
  
  Biology
Correct Answer
A. Chemistry

Explanation
Chemistry is the branch of science that is concerned with the composition and decomposition of matter. It studies the properties, structure, and behavior of substances, as well as the changes they undergo during chemical reactions. Chemistry is specifically focused on understanding the fundamental building blocks of matter, the elements, and how they combine to form compounds. By studying the composition and decomposition of matter, chemistry provides insights into the physical and chemical properties of substances, which has important applications in various fields such as medicine, materials science, and environmental science.

What century saw John Dalton publicize the Atomic Theory?
- A.
  
  19th century
- B.
  
  14th century
- C.
  
  17th century
- D.
  
  15th century
Correct Answer
A. 19th century

Explanation
John Dalton publicized the Atomic Theory in the 19th century. This theory proposed that all matter is made up of tiny indivisible particles called atoms. Dalton's work laid the foundation for modern atomic theory and revolutionized our understanding of the composition and behavior of matter. His ideas were groundbreaking and had a significant impact on the development of chemistry and the scientific community as a whole.

When was the molecular structure of DNA discovered?
- A.
  
  1959
- B.
  
  1953
- C.
  
  1958
- D.
  
  1951
Correct Answer
B. 1953

Explanation
In 1953, the molecular structure of DNA was discovered. This breakthrough discovery was made by James Watson and Francis Crick, along with the help of Rosalind Franklin's X-ray crystallography images. They proposed the double helix structure of DNA, which consists of two strands twisted around each other. This discovery revolutionized the field of genetics and laid the foundation for understanding the mechanisms of heredity and the basis of life itself.

Which of these is not part of an atom?
- A.
  
  Protium
- B.
  
  Proton
- C.
  
  Electron
- D.
  
  Neutron
Correct Answer
A. Protium

Explanation
Protium is not part of an atom. Protium is actually a type of hydrogen atom that consists of only one proton and no neutrons. It is the most common form of hydrogen and does not have any electrons. Protons, electrons, and neutrons are the three main particles that make up an atom. Protons have a positive charge, electrons have a negative charge, and neutrons have no charge. Therefore, Protium is not part of an atom as it is a specific type of hydrogen atom.

What year saw the completion of the "Human Genome Project"?
- A.
  
  2005
- B.
  
  2007
- C.
  
  2010
- D.
  
  2003
Correct Answer
D. 2003

Explanation
The completion of the "Human Genome Project" occurred in the year 2003. This project aimed to sequence and map all the genes present in the human genome. It involved an international collaboration of scientists and researchers who worked together to identify and understand the approximately 20,000-25,000 genes that make up human DNA. The successful completion of this project marked a significant milestone in the field of genetics and provided valuable insights into human health and disease.

Which of these is not a life science?
- A.
  
  Anatomy
- B.
  
  Physiology
- C.
  
  Physics
- D.
  
  Botany
Correct Answer
C. pHysics

Explanation
Physics is not a life science because it is the study of matter, energy, and the interactions between them, whereas life sciences focus on the study of living organisms and their processes. Anatomy, physiology, and botany are all branches of life sciences that involve the study of the structure and function of living organisms.

Who pioneered astronomy?
- A.
  
  Charles Lamarck
- B.
  
  Greg Philips
- C.
  
  Galileo Galili
- D.
  
  Albert Einstein
Correct Answer
C. Galileo Galili

Explanation
Galileo Galili is the correct answer because he is widely recognized as the pioneer of astronomy. He made significant contributions to the field by using telescopes to observe celestial bodies and challenging the prevailing geocentric model of the universe. Galileo's observations and discoveries, such as the moons of Jupiter and the phases of Venus, revolutionized our understanding of the cosmos and laid the foundation for modern astronomy. His work paved the way for future astronomers and greatly advanced our knowledge of the universe.
