the process in which populations gradually change over time
What is Evolution
100
Life cycle of an eukaryotic cell divided into three stages: Interphase, Mitosis and Cytokinesis
What is Cell Cycle
100
Chromosomes condense.
What is Prophase
100
A cell containing a single set of chromosomes (one of each kind - half)
What is haploid
100
reproduction that results from combining genetic material from two individuals (a male and a female). The result of meiosis.
What is sexual reproduction
200
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
200
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
200
Chromosomes line up
in the middle of the cell
What is Metaphase
200
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
200
A pair of chromosomes of the same size, shape and have the same gene; one from each parent.
What is homologous pairs
300
process by which organisms inherit advantageous traits that let them reproduce more successfully than the other organisms do.
What is What is Natural Selection
300
In eukaryotic cells, it is the part of the cell cycle during which the nucleus divides.
What is mitosis
300
Chromosomes separate
and pull to opposite sides of the cell.
What is Anaphase
300
A cell containing two full sets of chromosomes (2n - one from father and one from mother). In humans, the diploid number is 46.
What is Diploid
300
Male reproductive cell in animals. It is haploid and has a tail.
What is Sperm
400
natural differences within a species.
What is Variation
400
Ability to generate offspring.
What is reproduction
400
Nuclei form.
A new nuclear membrane forms around each group of chromosomes.
What is Telephase
400
A threadlike, gene-carrying structure found in the nucleus. Each consisting of one very long DNA molecule and associated proteins.
What is chromosome
400
Female reproductive cell in animals.
What is an Egg
500
an inherited trait that helps an organism survive and reproduce in its environment.
What is Adaptation
500
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
500
Reproduction, growth and repair
What are three reasons cell divide
500
Complex material made up of DNA and proteins.
What is chromatin
500
a section of the DNA (chromosome) that codes for a specific trait (e.g. eye color or hair color)
