- a bodys response to stimuli reverses the stimulus in effect turning it off for a while and keeps the body within normal range
- c process of cell division that results in the formation of gametes which are egg and sperm cells.
(used for creating human life)
- e diffusion of water through a selectively permeable membrane. water will move from an area with more present to an area with less water present. takes place in the kidneys which reabsorb large amounts of water. FOR WATER
5 Multiple choice questions
- 1. The dorsal cavity which contains the spinal and cranial cavity
2. The ventral cavity which contains the thoracic, abdominal and pelvic cavities
- Covalent bonds share electrons between atoms
(ex: H20 or water)
- Catalyst: speed up reactions without the use of external energy or heat
- Serous membranes are in closed body cavities where the serous fluid prevents friction between the two layers of the serous membrane.
---Thoracic cavity: partial pleura lines chest wall and cisceral pleura covers the lungs.
---Pericardial sac: parietal pericardium lines the fibrous pericardium and the visceral pericardium covers the heart muscle.
---Abdominal cavity: peritoneum lines the abdominal cavity and mesentary covers the abdominal organs
- 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
5 True/False questions
What is diffusion and how does it work? → 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)
What are the 7 types of connective tissue? → 1. Simple squamous -one layer of flat cells (alveoli of lungs, permits diffusion of gases)
2. Stratified squamous- many layers of cells (epidermis, lining of esophagus and vagina)
3. Transitional- many layers of cells (lining of bladder, permits expansion)
4. Cuboidal- one layer of cube shaped cells (thyroid gland, salivary gland, kidney tubules) excretory
5. Columnar- One layer of column shaped cells (lining of stomach, lining of small intestine and absorbs products in digestion)
6. Ciliated- one lay of columnar cells with cilia on free surfaces (lining of trachea to sweep mucus and dust pharynx and lining of fallopian tube to sweep ovum toward uterus)
What is the cell nucleus and what is its function? → Nucleus is within the cytoplasm and has a nuclear membrane with nucleoli and chromosomes of the cell. Nucleolus is where DNA and all genetic info for human traits lies.
What are the cell organelles and what do they do? → Nucleus is within the cytoplasm and has a nuclear membrane with nucleoli and chromosomes of the cell. Nucleolus is where DNA and all genetic info for human traits lies.
What is active transport and how does it work? → 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)
