100
abiotic nonliving portion of an ecosystem
What is abiotic
100
known for proposing the natural selection and survival of the fittest
What is Darwin known for
100
The synthesis of mRNA (messenger RNA) from a DNA template.
What is transcription
100
Divides the nucleus so that both daughter cells are identical
What is Mitosis
100
cells to fight current infection
What are plasma cells
200
climograph a graph that shows information about the temperature and precipitation in a particular location of period of time
What is climograph
200
Micro - evolution in a population macroevolution evolution that occurs at or above the level of species
What is difference between microevolution and macroevolution
200
The nucleus
Where does transcription occur
200
Reduction division; four genetically variable daughter cells are produced, and they contain half the genetic material
What is Meiosis
200
It performs cellular respiration. This means it takes in nutrients from the cell, breaks it down, and turns it into energy
What is Mitochondria
300
Introduced Species, Overharvesting, Global Climate Change and Habitat Loss.
What is four main threats to biodiversity
300
genotype the actual genes, often designated by letters(G,g) phenotype the physical manifestation of genes
What is the difference between phenotype and genotype
300
RNA has ribose sugar instead of deoxyribose, and uracil (U) instead of thymine (T). Also, RNA is usually only a single strand, rather than a double helix.
What is the difference between RNA & DNA
300
Growth;cell carries out normal activities. Occurs at the end of the G1phase; if conditions are not right or if the cell is not supposed to divide, it remains in an extended G1 phase called the G0 phase
What is G1 Phase and checkpoint
300
Provide support outside the plasma membrane; made of cellulose in plants. In plant cell
What is the cell wall and what type of cell does it belong to
400
R-Species that exhibit rapid growth (J-shaped curve), where opportunistic species (grass/insects) quickly invade habitats, reproduce, and die. K-selected species Species where population size remains constant (ex.elephants/humans) and produce a small number of relatively large offspring that require much care until maturation
What is the difference between k and r selected species
400
analgous structures anatomical features that serve the same purpose, but don't suggest a common ancestor
What is analgous structures
400
Methionine (met), the start codon.
AUG codes for
400
Uncontrolled cell growth and division; transformed cells proliferate without regulatory mechanisms
What causes cancer
400
ψ= ψS + ψP
What is the formula for water potential?
500
Describes how mortality of individuals in a species varies during their lifetimes.
What is survivorship curves
500
Disruptive Selection:occurs when natural selection favors both extremes Directional Selection:occurs when natural selection favors one extreme of continuous variation.
What is the difference between disruptive and directional selection
500
The DNA sequence that allow RNA polymerase to begin transcription.
What is the Promoter
500
Made of two identical halves called sister chromatids joined at a centromere
What is chromosomes
