Life
Inherited characteristic of an organism that enhances its survival and reproduction in a specific environment.
What is an adaptation?
a type of cell lacking a membrane enclosed nucleus and membrane enclosed organelles
The energy used by most organisms for metabolism and growth ultimately comes from
What is the Sun?
What are the hydrophobic and hydrophilic parts of a phospholipid
Hydrophobic: tails
Hydrophilic: head
genetic change in a population or species over generations
DNA's building block
What is a nucleotide?
Make observations
Ask question
Form hypothesis
Make prediction
Experiment
Statistical tests
What is the scientific method?
Flexible model of the plasma membrane composed of a two layers of lipid molecules and with protein molecules dispersed within.
What is the fluid mosaic model?
The process by which information encoded in DNA directs the synthesis of proteins or, in some cases, RNAs that are not translated into proteins and instead function as RNAs.
Rank from least to most organized:
tissue, organ system, organisms, cells, organ
Cells → tissue → organs → organ system → organisms
Feedback that either
1.increases the change or output: the result of a reaction is amplified to make it occur more quickly. 2. reduces the change or output: the result of a reaction is reduced to bring the system back to a stable state
What is positive and negative feedback
Protein that is integrated into the lipid bilayer in whole
What is an integral protein?
Eukaryotic cell organelles, such as mitochondria and plastids, evolved from free-living prokaryotes
What is the endosymbiotic theory?
Eukaryotic organisms that decompose dead organisms and absorb the nutrients are generally found in which kingdom?
Fungi
New properties that arise with each step upward in the hierarchy of life, owing to the arrangement and interactions of parts as complexity increases.
Consists of a carbohydrate covalently bonded to a lipid.
What is a glycolipid?
1. Order
2. Regulation
3. Energy Processing
4. Evolutionary Adaptation
5. Response to the Environment
6. Reproduction
7. Growth and Development
What is the seven characteristics of life?
Of the three domains Bacteria, Archaea, and Eukarya, which one is prokayotic?
Archaea
1. A type of logic in which specific results are predicted from a general premise.
2. moves from a set of specific observations (humans require organic molecules, fish require organic molecules) to reach a general conclusion (all animals require organic molecules
1. What is deductive reasoning?
2. What is inductive reasoning?
Proteins are attached to the surface of the bimolecular lipid layer
What is a peripheral membrane protein?
