What are the characteristics of living things?
|
All have cellular organization, contain similar chemicals, use energy, grow & develop, respond to their surroundings, and reproduce
|
|
|
What is the difference between growth and development?
|
Growth is when you change in size, development is when you become more complex
|
|
|
Why does a controlled experiment correct the mistake idea of spontaneous generation?
|
If there were really spontaneous generations there would be flies in the closed jar too. Putting the lid on it made it a controlled experiment
|
|
|
Living things must satisfy their basic needs for:
|
Energy, water living space, and stable internal conditions
|
|
|
Autotrophs
|
An organism that makes its own food
|
|
|
Heterotrophs
|
An organism that cannot make for itself, and must obtain food by eating other organisms
|
|
|
Homeostatis
|
A body or cell's ability to regulate its own environment, regardless of the outside conditions.
|
|
|
Unicellular
|
A type of organism that is made up of a single cell
|
|
|
Multicellular
|
A type of organism that is made up of many cells
|
|
|
How was earth's atmosphere 3.6 billion years ago?
|
They had many different gases. They had similar main gases as us like nitrogen, but no oxygen
|
|
|
What did Harold Urey and Stanley Miller model in their experiment?
|
They had a flask that symbolized the earth 3.6 billion years ago and put water in it to symbolize the ocean, gases 3.6 billion years ago n, co2,vapor, and methane. They put an electric shock to symbolize lightning and the water turned cloudy that made proteins which are the building blocks of life.

What are the seven levels of classification?
|
Kingdom, Phylum, Class, Order, Family, Genus, Species
|
|
|
Genus
|
A classification grouping that consists of a number similar, closely related species
|
|
|
Species
|
A group of similar organisms that can produce fertile offspring in nature
|
|
|
Binomial nomenclature
|
The naming system for organisms in which each organism given a two-part name-a genus name and a species name
|
|
|
All organisms are grouped into six kingdoms
|
Archebacteria, Eubacteria, Protists, Fungi, Plants, Animals
|
|
|
Describe few characteristics of each kingdoms:
|
Archebacteria place in Pacific ocean where hot gases and molten. Eubacteria produces yogurt. Protists includes slime molds like in Dallas made up of eukaryotes organisms with nuclei. Mushrooms, mild, and mildew are all fungi. Plants are multicellular they are autotrophs and can grow very tall. Animals are the same as plants except they are heterotrophs.
|
|
|
Prokaryote
|
An organism whose cells lack nucleus and some other cell structures
|
|
|
Eukaryote
|
An organism with cells that contain nuclei and other cell structures
|
|
|
Nucleus
|
The dense area in a eukaryote cell that contains nucleic acids, the chemical instructions that direct the cell's activities
|
