Cellular Processes
Maintaining Internal Stability
What is homeostasis
The order from smallest to largest:
organ, cell, organelle, tissue, organ system
What is
organelle, cell, tissue, organ, organ system
The complementary sequence to the DNA strand:
ATC
What is TAG
The place where fertilization occurs.
What is the oviduct
An example of an abiotic factor.
What is light, temperature, water, soil
Also known as biological catalysts
What are enzymes
The 2 differences between active transport and passive transport.
Active: Low to High, ATP needed
Passive: High to Low, NO ATP needed
The order from smallest to largest:
Chromosome, Nucleotide, Nucleus, Gene
What is
Nucleotide, Gene, Chromosome, Nucleus
2 differences between mitosis and meiosis
Mitosis: identical cells, same number of chromosomes
Meiosis: differences between cells, half the number of chromosomes
All of the biotic and abiotic factors in an area.
What is an ecosystem
When an enzyme changes shape due to high temperatures or extreme pH levels.
What is denature
What is the formula for finding the size of a unicellular organism under the microscope?
What is the diameter/# of cells that fit across the field of view?
Choosing the two parents to breed together.
What is selective breeding.
The process during Prophase I when genes are exchanged between homologous chromosomes
What is crossing over
2 types of the organisms that return nutrients to the environment.
What are bacteria and fungi
The entire chemical reaction for photosynthesis
What is water + carbon dioxide using sunlight = glucose + oxygen
The four large categories of organic molecules
What are nucleic acids, carbohydrates, proteins, and lipids.
A combination of DNA from 2 or more organisms.
What is recombinant DNA
When cells become specialized.
What is differentiation
A series of changes that modify environments over time.
What is ecological succession.
Examples include regulating gas exchange in plants, regulating glucose levels with insulin, and regulating body temperature. NOT homeostasis....
What are feedback mechanisms
All of the chemical reactions that occur in your body.
What is metabolism
2 differences between DNA and mRNA
DNA: ATCG, 2 strands
mRNA: AUCG, 1 strand
The 3 things produced by the ovary and the 2 things produced by the testes
Ovary: eggs, estrogen, progesterone
Testes: sperm, testosterone
The cause and one effect of the following:
Ozone depletion
Global Warming
Ozone: use of CFC's, more UV light coming to earth
Global Warming: Burning fossil fuels, increase in earth's temperature
