What is diffusion?
Diffusion is the movement of particles from an area of high concentration to an area of low concentration
100
what is energy conversion?
process of changing one form of energy into another.

Give an example of disease involving malfunction of proteins

viruses, cancer, Alzheimer's, and Mad Cow

What is Homeostasis?

Homeostasis is the tendency to maintain stable equilibrium of physiological processes

100

What is Osmosis?

the movement of water through a cell membrane

Give an example of diffusion :)

Active Transport, Passive Transport, Osmosis, and Waste Removal

What is cellular respiration?

Occurs in the mitochondria of eukaryotes, the cytoplasm of prokaryotes. In the process, oxygen is consumed and carbon dioxide is generated.

200

What is protein synthesis?

a process within a cell in which amino acids are joined together to make a protein. 


It requires a messenger RNA and takes place on ribosomes.

200
What usually results when an organism fails to maintain homeostasis? A) Growth rates within organs become equal. B) The organism becomes ill or may die. C) The water balance in the tissues of the organism stabilizes. D) A constant sugar supply for the cells is stopped.
B- The organism becomes ill or may die

What is mitochondria?

cell organelle that convert glucose into energy (ATP) 

300

what is active transport?

The movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.

300

What is photosynthesis?

Uses sunlight to synthesize foods from carbon dioxide and water.

300

What are the two main stages of protein synthesis in order?

transcription (mRNA) and translation (tRNA)

300

What is Chloroplast?

Organelle of plants and some other organisms use energy from the sunlight---photosynthesis

300

What are ribosomes?

organelle that synthesise proteins 

400

what is passive transport?

transport of a substance across a cell membrane by diffusion; expenditure of energy is not required.

400

what is fermentation?

Anaerobic breakdown of a substance by bacteria, yeasts, or other microorganisms, typically giving off carbon dioxide and Hear

400
What is the first step of protein synthesis? 1. The AUG codon signals both the interaction of the ribosome with m-RNA and also the tRNA with the anticodons (UAC). 2.the transcription of mRNA from a DNA gene in the nucleus. 3.Elongation of the peptide begins as various tRNA's read the next codon.
2. the transcription of mRNA from a DNA gene in the nucleus.
400

what is the nucleus?

large structure inside some cells that contains the cell's DNA and controls the cell's carbs.

400
what is active transport?
the movement of particles from low to high concentration (requires energy)
500

what are lysosomes?

an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes 

500

What is chemosynthesis?

Using energy derived from reactions involving inorganic chemicals (Rocks), typically in the absence of sunlight.

500

Why is protein synthesis important for living systems?

Without protein synthesis, living things could not grow or heal itself.

500

What is the purpose of homeostasis?

regulates its internal environment and tends to maintain a stable, relatively constant condition of properties such as temperature or pH.

500

What is Mad Cow Disease?

is a fatal, neurodegenerative disease in cattle, that causes a spongy degeneration in the brain and spinal cord
