Trivia Questions On Characteristics Of Life! Quiz

2.

Homeostasis means

Change over long periods of time.
Keeping things the same.
rapid change.
The same thing as evolution.

Correct Answer

A. Keeping things the same.

Explanation

Homeostasis refers to the ability of an organism or system to maintain a stable internal environment despite external changes. It involves various physiological processes that work together to regulate temperature, pH levels, blood sugar, and other variables within a narrow range. By keeping things the same, homeostasis ensures that an organism can function optimally and maintain its internal balance. It is not related to rapid change, evolution, or change over long periods of time.

Which of the following is not necessarily a characteristic of living things?

Homeostasis
Metabolism
complexity
reproduction

Correct Answer

A. complexity

Explanation

Complexity is not necessarily a characteristic of living things because there are some living organisms that are simple in structure and organization, such as bacteria. Although complexity can be observed in many living organisms, it is not a defining characteristic that all living things must possess. Homeostasis refers to the ability of an organism to maintain a stable internal environment, metabolism refers to the chemical processes that occur within an organism to sustain life, and reproduction refers to the ability of an organism to produce offspring.

4.

The smallest units that can carry on all the functions of life are called

Molecules.
cells.
Organelles.
Species.

Correct Answer

A. cells.

Explanation

Cells are the smallest units that can carry on all the functions of life. They are the basic building blocks of all living organisms and are capable of reproducing, growing, responding to stimuli, and carrying out metabolic activities. Cells contain various organelles, such as the nucleus, mitochondria, and ribosomes, which perform specific functions within the cell. Molecules, on the other hand, are made up of atoms and are the smallest units of chemical compounds. Species, on the other hand, refers to a group of organisms that can interbreed and produce fertile offspring. Therefore, cells are the correct answer as they are the fundamental units of life.

Living things

Need energy for life processes.
Have the ability to reproduce.
Are composed of cells.
All of the above

Correct Answer

A. All of the above

Explanation

The correct answer is "All of the above" because living things do indeed need energy for life processes, such as metabolism and growth. They also have the ability to reproduce, either sexually or asexually, to ensure the continuation of their species. Additionally, living things are composed of cells, which are the basic structural and functional units of life. Therefore, all three statements are true and encompass the characteristics of living things.

6.

All organisms are composed of

Diatoms.
cellulose.
Cells.
None of the answers

Correct Answer

A. Cells.

Explanation

The correct answer is "cells" because cells are the basic structural and functional units of all living organisms. They are responsible for carrying out essential life processes and are the building blocks of tissues, organs, and systems in organisms. Diatoms and cellulose are specific components or substances found in some organisms, but not all organisms are composed of them. Therefore, the most accurate and inclusive answer is "cells."

7.

All living things maintain a balance within their cells and the environment through the process of

Growth.
Development.
Homeostasis.
Evolution.

Correct Answer

A. Homeostasis.

Explanation

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in the external environment. It involves regulating various factors such as temperature, pH levels, and nutrient levels to ensure optimal conditions for cellular function and survival. Growth and development are related processes, but they do not specifically refer to the maintenance of balance. Evolution, on the other hand, refers to the gradual change in species over time and is not directly related to maintaining balance within cells and the environment.

Rate this question:

8.

Which of the following is a characteristic of all living things?

Movement
Photosynthesis
Development
Cellular organization

Correct Answer

A. Development

Explanation

Development is a characteristic of all living things because it refers to the process of growth, maturation, and differentiation from a simple to a more complex form. Living organisms undergo various stages of development throughout their lifespan, including embryonic development, growth, and aging. This process allows living organisms to adapt, reproduce, and evolve over time. Development is a fundamental characteristic that distinguishes living things from non-living things.
