First true cells were. . .
A change in life forms that has taken place in the past and will take place in the future
Holds the code
The construction of family trees in based on shared similarities and gene sequences
Similarities that result from common ancestry should also be similar at a smaller level of detail
Steven Jay Gould
Species remain static for long periods of time and then change abruptly
Mutation, Variation, Selection pressures
Use a bible account of creation and reject and scientific account that conflicts with scripture
Intelligent design creationists
Work within the framework of science to find evidence of design in nature and state that biological systems are so complex that only an intelligent designer could have made them
Believe that God created the universe and all life and believe that evolution is, in fact, God's creative process and part of the plan
The study of biological traits
Variant of a gene. Can be dominant or recessive and are the basis of varied traits
Non sex cells. Contain a full complement of chromosomes. Characteristic to their species. Referred to as the diploid number of chromosomes
Sex cells. Cells which carry genetic information for sexual reproduction, Contain one half compliment for chromosomes characteristic to their species. Referred to as the haploid number of chromosomes
The additive effect of two or more genes on a single phenotype
Sickle cell anemia
Red blood cells are not concave
Any change in the nucleotide sequence in RNA
Paired gonads within scrotum, sperm and steroids are produced here
Tightly coiled duct where sperm maturation occurs
Delivers sperm through abdomen to ejaculatory duct
Duct through penis where sperm and urine exit
Seminal fluid, contains sperm, fluid and ATP producing nutrients
Adds fluid to semen
Contribute nutrients to semen
Contributes mucoid fluid to semen
Secretes gonadotropin releasing hormone
Produce eggs and steroid hormones
Conduct the egg to the uterus, fertilization occurs here
Ovulation day is typically. . .
Cells from follicle that nourished egg in ovary
Layer that covers plasma membrane- will form fertilization envelope
Contains sperm nucleus and acrosome
Stanly Miller's Experiment 1952
Amino acids, simple sugars, and most of the building blocks for DNA and RNA were produced.
Give off radio waves
Contains ozone, created weather
The greenhouse effect
The process in which the absorption of infrared radiation by an atmosphere warms a planet
Reaction of photosynthesis
Site of gas exchange. Co2 in and O2 out.
Less solute than the cell. Higher water concentration.
More solute than the cell. Lower water concentration.
Same solute as the cell. Water comes in and goes out. Bad for plant.
