Random Biology
The concept that organisms who are the best suited to their environment will be the most successful
What is natural selection
These simple molecules form the basis of all proteins
What are amino acids?
Differences among individuals within a population.
What is genetic variation?
The process in which carbon is cycled between the atmosphere, land, water, and organisms
What is the carbon cycle?
A diagram showing feeding relationships among multiple organisms.
What is a food web?
Which cell type does not have a nucleus?
What is a prokaryote? (or prokaryotic cell)
The process that copies DNA before cell division.
What is DNA replication?
This process is used to make new body cells during growth and repair
What is mitosis
A molecule that serves as a fast source of energy? (created by plants)
Glucose
A biomolecule that serves as a fast source of energy?
What are carbohydrates?
How much energy is lost from one trophic level to the next?
90%
movement of particles from an area of higher concentration to an area of lower concentration
What is diffusion
A change in the DNA sequence that can create new genetic variation.
What is a mutation?
This organelle produces sugars in plants
What is the chloroplast.
If the producers contain 10,000 Kcal, then how much energy will the secondary consumers contain?
What is 100 Kcal?
This process keeps an organism's internal environment stable despite changes in the external environment.
What is homeostasis?
This process produces four genetically unique cells, each with half the number of chromosomes as in the parent
meiosis
These are biological systems that detect change and help return conditions to normal.
What is a feedback mechanism?
Which organelle produces ATP?
Mitochondria
What type of cell is a chloroplast found in?
what is a plant cell
The process by which water moves through the cell membrane to balance out a high concentration of solutes.
What is osmosis?
Which characteristics do all living organisms share (list at least 3)
All living things are: made of cells, use energy, respond to changes in the environment, grow and develop, reproduce
This process converts light energy into food
What is photosynthesis
Individuals with favorable traits survive and reproduce more successfully.
What is natural selection?
This process cells use to generate energy (ATP) without oxygen
What is anaerobic respiration
