the process in which populations gradually change over time.
What is Evolution
100
Chromosomes condense.
What is Prophase (Pmat)
100
The cell grows and carries out normal life functions; organelles duplicate; DNA replicates; the cell grows twice its size and prepares for mitosis
What is Interphase
100
Cell division that results in 4 daughter cells that each are haploid (1n) having half the number of chromosomes as the parent cell
What is Meiosis
100
A threadlike, gene-carrying structure found in the nucleus. Each consisting of one very long DNA molecule and associated proteins.
What is chromosome
200
process by which organisms inherit advantageous traits that let them reproduce more successfully than the other organisms do.
What is Natural selection
200
Chromosomes line up
in the middle of the cell.
What is Metaphase (pMat)
200
In eukaryotic cells, it is the part of the cell cycle during which the nucleus divides.
What is mitosis
200
Symbol for diploid number of chromosomes in a cell.
What is 2n
200
Ability to generate offspring
What is reproduction
300
the total number of fossils that have been discovered.
The fossil record provides evidence about the order in which species have existed through time, and how they have changed over time.
What is Fossil Record
300
Chromosomes separate
and pull to opposite sides of the cell.
What is Anaphase (pmAt)
300
Reproduction, growth and repair
What is three reasons cells divide
300
Symbol for haploid number of chromosomes in a cell.
What is 1n
300
Complex material made up of DNA and proteins.
What is chromatin
400
A scientist best known for his contributions to the science of evolution. Sailed on the HMS Beagle and explored the Galapagos Islands discovering different species of finches on each island.
What is Charles Darwin
400
Nuclei form.
A new nuclear membrane forms around each group of chromosomes.
What is Telophase (pmaT)
400
The division of the parent's cytoplasm pinching into two new identical daughter cells in animal cells. In plant cells a CELL PLATE forms separating the two new cells.
What is Cytokinesis
400
female chromosome that controls development of sexual characteristics
What is x chromosome
400
Two identical structures of a chromosome held together by a CENTROMERE.
What is chromatids
500
The human practice of breeding organisms (plants or animals) with specific traits in order to produce offspring with those desired traits.
What is Artificial Selection
500
Life cycle of an eukaryotic cell divided into three stages: Interphase, Mitosis and Cytokinesis
What is Cell Cycle
500
Nuclei form.
A new nuclear membrane forms around each group of chromosomes.
What is Telophase (pmaT)
500
male chromosome that controls development of sexual characteristics
