- What is a negative feedback mechanism?
- What is diffusion and how does it work?
- What is the formula for glucose?
- What is mitosis?
- What is facilitated diffusion and how does it work?
- a movement of molecules from an area of greater concentration to an area of lesser concentration along the concentration gradient. Very slow process. FOR MOLECULES
(Example: exchange of gases in lungs or body tissues)
- b C6H12O6
- c Cell division involving one cell with the diploid number of chromosomes dividing into two identical cells.
(used for repair of tissues and growth of the organism)
- d bodys response to stimuli reverses the stimulus in effect turning it off for a while and keeps the body within normal range
- e molecules move through a membrane from an area of greater concentration to an area of lesser concentration with the help of a carrier enzyme
(Example: intake of glucose by most cells)
5 Multiple choice questions
- Force or attraction between positive and negative charges that keeps atoms closely together
- requires ATP to move molecules from an area of lesser to an area of greater concentration.
(Example: sodium pumps to move Na+ out of the cells)
- Positive and negative feedback mechanisms
- secretion of an endocrine gland that has effects on target organs
(ex: Insulin - enables cells to take in glucose and lowers glucose levels. Growth hormone - increases protein synthesis and cell division)
5 True/False questions
What is a buffer and what does it do? → Catalyst: speed up reactions without the use of external energy or heat
What are the different kinds of bonding atoms? → 1. Sagittal plane which divides left from right (cut down the middle would be mid-sagittal)
2. Frontal plane which divides the body front to back (Coronal)
3. Transverse plane which is a horizontal plane that separates the body into upper and lower portions (cuts you at belly button into upper body and lower body)
What is contained in the pelvic cavity? → Spinal vertebre
What is cellular respiration? → a watery solution (cytosol) of minerals, gases, organic molecules and cell organelles are found. it gives the cell its shape
What is the cell membrane made up of and what is its function? → outer boundary of a cell made up of phospholipids, cholesterol and proteins.
its main job is to protect the cell and acts as a barrier for communication and assists in transport
