Life!
All living things are made of one or more of these small units of life.
What are cells?
Water molecules have a positively charged end and a negatively charged end, meaning they are this.
What is polar?
A group of organisms living in a specific area and who all belong to the same species are called this.
What is a population?
This type of bond involves atoms donating and recieving electrons, producing charged particles that are attracted to each other.
What is an ionic bond?
All scientific names must be written using this kind of formatting.
What is italicized?
Every living thing we see today developed over millions of years, thanks to this slow process.
What is evolution?
These weak bonds form between the oppositvely charged ends of water molecules.
What are hydrogen bonds?
This Swedish scientist is credited with developing the binomial naming system as well as the field of taxonomy.
Chemical reactions that follow this pattern:
AB --> A + B
are classified as this kind of reactions.
What is decomposition?
The two parts of a scientific name represent these two most specific taxonomic ranks.
What are genus and species.
All living things must maintain stable internal conditions, which is also known as this.
What is homeostasis?
Water's ability to dissolve many different substances gives it this impressive nickname.
What is the universal solvent?
There are currently 8 levels of organization in taxonomy, ordered from most general at the top down to most specific at the bottom. Name them in order.
What are Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species?
Bonds that involve atoms sharing electrons are called this.
What are covalent bonds?
Hannah is writing a paper about her favorite species, the pygmy hippopotamus, choeropsis liberiensis. She italicizes the name each time she writes it and she assumes this is the correct way to use the scientific name.
But she is wrong. Because she forgot to do this.
What is capitalize the Genus. (Choeropsis liberiensis.)
All organisms are capable of reproduction, but only some do this, which results in identical offspring.
What is asexual reproduction?
The attraction between water molecules and different molecules is called this.
What is adhesion?
A biological community plus the non-living, physical environment in which organisms interact is called this.
What is an ecosystem?
The following equation:
Fe +CuCl2 → FeCl2 + Cu
is classified as this type of reaction.
What is a single displacement reaction?
Large geographic areas with the same temperature, precipitation, and types of species are called this.
What are biomes?
Organisms use these processes to convert food into usable energy.
What is metabolism?
Water requires a lot of energy to change temperatue, due to this property.
What is high specific heat capacity?
This type of organism lacks a nucleus inside of it's cells.
What is a prokaryote?
The chemicals on the left side of a reaction are called this and those on the right side of a reaction are called this.
What are reactants and products?
The part of the Earth where life exists is called this.
