Participation Pop Quizzes (Topic 1-4)

Question 1

Biology, in general, the study of what exactly?

Answer 1

life and all its aspect

Question 2

Life is diverse, yet all life must share what properties to be considered living?

Answer 2

Sensitivity - respond to stimuli

Organization - ordered complexity

Growth, development and reproduction

Energy utilization - producers, consumers, and decomposers

Homeostasis - must maintain constant internal conditions

Evolutionary adaptations - ability to adapt to the environment

Question 3

Are fungi considered living?

Answer 3

Yes, they fulfill all the requirements of life, energy utilization, reproduction, growth, homeostasis, evolutionary adaptations,

Question 4

Are viruses considered alive? And why are they considered alive or not alive?

Answer 4

Not they are not considered to be alive because they do not fulfill the requirements of life….

Cellular Structure: Viruses are not made up of cells. They are simply packages of DNA or RNA, surrounded by a protein coat.

Metabolism: Viruses do not have their own metabolism. They rely on the host cell’s metabolic machinery for energy production.

Reproduction: Viruses cannot reproduce independently. They need to infect a host cell and use the host’s cellular machinery to replicate.

Growth and Development: Viruses do not grow or develop. Once they are assembled in the host cell, they remain the same size.

Response to Environment: Viruses do not respond to changes in their environment like living organisms do. They do not move towards or away from stimuli.
