Concept explainers
Concept introduction:
Biologists are continuously studying about the exact concept of life. Living things are too diverse and they consist of the same basic components as non-living things. As per a biologist’s point of view, the life of living organisms is in increasingly inclusive levels of organization.
Answer to Problem 1SQ
Correct answer: Atoms are fundamental building blocks of all matter. Hence, option a. is the correct answer.
Explanation of Solution
Reasons for the correct statement:
Biologists view life in increasing levels of organization. The lowest level of
Option a. is given as “atoms”. An atom is the smallest basic unit of all substances, either living or non-living. Atoms, and the fundamental particles that arrange them, are the main building blocks of all matter. Hence, option a. is the correct answer.
Reasons for the incorrect statements:
Option b. is given as “molecule”. Atoms join with another atom; together, they form molecules. A molecule is larger than an atom. Hence, option b. is an incorrect answer.
Option c. is given as “cell”. The “molecules of life” are together arranged to form the smallest unit of life called the cell. Hence, option c. is an incorrect answer.
Option d. is given as “organisms”. An organism is an individual that consists of one or more cells. Hence, option d. is an incorrect answer.
Hence, options b., c., and d. are incorrect.
An atom is the fundamental and smallest unit of a substance.
