Science - Topic 1 - Properties of Life and Viruses

What is Biology?

study of life

What 2 words did Biology originate from?

bios and logos

What does bios and logos mean, respectively?

life and study

What is the Filipino term for Biology? ( asides from Biolohiya )

Haynayan

What are all the Levels of Organization?

Atom, Molecule, Cells, Tissues, Organs, Organ System, Organism, Population, Community, Ecosystem, Biosphere

What are the 7 Properties of Life, also known as the System of Living Things?

Order/Organization

Metabolism

Homeostasis

Response to Stimuli

Reproduction

Growth and Development

Evolutionary Adaptation

What is Order/Organization?

living organisms are composed of one or more cells

Can one cell carry every function needed for an organism to stay alive?

Yes

What is Metabolism?

the sum of all chemical reactions occurring within a living organism that converts nutrients into energy and essential molecules needed for growth

What is Response to Stimuli?

refers to the ability of a living organism to respond to internal and external stimuli

What is Homeostasis?

refers to the ability of a living organism to maintain a stable internal environment despite changes in external condition

What is Reproduction?

refers to the ability of a living organism to be able to produce another organism sexually or asexually

What is Growth and Development?

refers to the ability of a living organism to increase in size and undergo various stages of development throughout their lifespan

What is Evolutionary Adaptation?

refers to the ability of a living organism to be able to adapt to changing environment ( not the same as Homeostasis )

Are virsuses alive?

No

Do viruses steal some of the properties of life from it’s host, rather than having one itself?

Yes

What is the name of the virus mentioned in the table Ma’am Gre showed? ( Example Given )

SARS-CoV-2

What 2 Properties of Life / System of Living Things do Viruses Have?

Reproduction and Evolutionary Adaptation

What is the Celluar Organization of the Virus?

• not made of cells

• consists of genetic material surrounded by a protein coat

What is the Metabolism of the Virus?

• does not have metabolic processes

• relies on a host cell for replication

What is the Homeostasis of the Virus?

• does not maintain Homeostasis

• relies on the host cell’s environment

What is the Response to Stimuli of the Virus?

• does not respond to stimuli

• interacts with host cells through binding

What is the Reproduction of the Virus?

• reproduces by hijacking host cells to create new virus particles

What is the Growth and Development of the Virus?

• does not grow

• it replicates by assembling new virus particles within host cells

What is the Evolutionary Adaptation of the Virus?

• can evolve rapidly through mutations, but this is a result of interactions with the host cells, not self-directed adaptation
