Biology Unit 1

QuestionAnswer
Biology Definition Study of life
Fundamental properties of life Reproduction, growth and development, energy use, homeostasis, Response to environment
Smallest unit of life the cell
Prokaryote domain Archaea, bacteria
Eukaryotic domain Eukarea
Chemicals are _______ in an ecosystem recycled
Why aren't viruses considered living? because they can't reproduce
Five unifying themes of life Organization, structure, function, information flow, organization of matter
Biosphere Earth
Ecosystem Living and non living
Communities species living and interacting with each other.
Population group of a species chilling
Organism individual
Organ tissue bound together to serve a specific purpose
Tissue cells together for a purpose
Molecules Chemical compounds
Emergent property Individual components produce new functions not present in previous levels. When they emerge/come together they can perform specific functions that they cannot alone.
There is correlation between form and function
DNA is the genetic information for all life
Proteins are the building block of life
Energy _____ flows through an ecosystem
Every time energy is transformed A large amount is lost through heat energy
Evolution is the process in which the unity and diversity of life is achieved
Basic definition of chemistry making and breaking bonds
Smallest unit of matter Atom
Bulk of elements in human in body O, C, N, H
Valance electrons determine the reactivity of a element
Energy level _____ the further away from the center increase
Chemical bonds store potential energy, sharing or transferring electrons
Ion charged atom

Ionic bond Second strongest bond, not super strong in water
Covalent bond sharing electrons. strongest bond
Polar Bond is unequal. - hydrophilic
Nonpolar Bond is equal - hydrophobic
Hydrogen bonds electrical attractions among polar covalent molecules, weakest bonds
Ocean acidification Bicarbonate is removed from the ocean because carbon keeps forming bonds into bicarbonate instead of carbonate

Phospholipids consist of a phosphate group and two fatty acid tales
Sertiod are lipids, hydrophobic and made up of three carbon rings and a dog house.
What does cholesterol do in the phospholipid bilayer? It controls the viscosity of the phospholipid bilayer
Polar molecules are soluble in other polar molecules
DNA and RNA have Phosphate, sugar and a base pair
DNA base pair AT,GC

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
