| Question | Answer |
|---|---|
| Prostaglandins and steroids share | a ring structure in their molecules |
| When 2 molecules of glucose are joined, they form which disaccharide | Maltose |
| Which of the following is an active transport process | Endocytosis |
| Meiotic division occurs | in primitive sex cells |
| makes proteins by translation | RNA |
| Three types of specific carbohydrates | monosaccharides (simple sugars), disaccharides (double sugars), polysaccharides (complex sugars). |
| positive feedback system | accelerate a change |
| negative feedback system | reverses a chage |
| receptors | detect changes in enviroment in skin |
| effectors | implements a response to restore balance |
| control center | processes info and decides on response (hypothalamus) |
| lipids that form hormones like cortisone, estrogen and testosterone | steroids |
| 23 chromosomes per cells in humans are | haploid |
| amino group in amino acid | NH3+ |
| structural lipid found in a cell membrane | phospholipid and steroid |
| free radical | functional group that is temporarily unattached, highly reactive due to unpaired electrons |
| difussion | uses cellular energy |
| when chromosomes align across the equator | metaphase |
| ectodern layer | skin cells, neurons, pigment cells |
| mesoderm layer | skeletal muscle, tubule cell in kidney, rbc's, smooth muscle, cardiac muscle |
| endoderm layer | lung cell, thyroid cell, pancreatic cell |
| phospholipids have a | lipids bilayer; hydrophobic tails and hydophilic heads |
| epidermis/ 5 layers/epithelial tissue | makes keratin, rapid cell division/skin color basale,spinosum,granulosum,lucidum, corneum |
| Tactile epithelial cells, also called Merkel cells, | located in the deepest layer of the epidermis they connect to sensory nerve endings to form structures that serve as light touch receptor |
| Dermis/2 layers/connective tissue | papillary dermis(collagen,protein) reticular dermis (anchors,arrector pilli) |
| Hypodermis/ 1 layer | subcutaneous fat, muscle sits below this layer |
| axial | skull, ribcage, vertebral columm |
| apendicular | 2 legs, 2 arms, hips |
| diaphysis | shaft of bone/ yellow marrow |
| epiphysis | knuckle of bones(ends) red marrow |
| methaphysis | growing plate |
| hematopoeisis | stem cells are created and differentiate into rbc's, wbc's and platelets and subtypes |
| type of muscle w/o T-Tubules | smooth muscle |
