Cell Structure
Prokaryotes have a single circular chromosome, eukaryotes have several linear chromosomes.
What is genome difference between cells
Anything that occupies space and has mass
What is matter?
Electron loss
What is Oxidation?
Geologists suggested that Earth changed over vast periods of time
What is geologic time scale?
Non-living, obligate, intracellular parasites
What is virus?
Made of folded protein and rRNA, critical for the translation step of gene expression.
What is Ribosomes
The capacity to do work
What is energy?
Electron gain
What is Reduction?
Layers of accumulated sediments that allow us to approximate the age of the layer, deeper layers are older
What is geologic strata?
Outer protein coating of a virus
What is viral capsid?
The area within a cell and the material found there.
What is Cytoplasm
Energy of motion or any energy in active use
What is kinetic energy?
Reaction where oxidation and reduction reactions occur together; for example:
What is redox reactions?
Sequence in rock layers, record of time and process of evolution
What is fossil record?
An outer membrane taken from the previous host
What is viral envelope?
Proteins are suspended in a 'sea' of phospholipids.
What is fluid mosaic model
Stored energy
What is stored energy?
Electron shuttle used in respiration; NAD+ is reduced form and NADH is oxidized form
What is NAD+/NADH?
Group of individuals of the same species
What is population?
Occurs when viruses push their way out of the host, taking membrane with them
What is budding?
Double layer membrane perforated by numerous nuclear pores, each with a ring of 'guard proteins.'
What is nuclear envelope
Energy cannot be created nor destroyed, it can only change form
What is conservation of energy?
Reaction that breaks apart glucose in both prokaryotes and eukaryotes
What is Glycolysis?
Selection where nature provides the variations and humans select for useful or best traits
What is artificial selection?
A virus that infects bacteria
What is bacteriophage?
