Explain how temperature is an example of a homeostatic feedback control system in your body? Is this a negative or positive feedback system? Explain.
Temperature is an example of homeostatic feedback control system because if the body temperature is higher or lower than normal your body makes it go back to normal. It is a negative feedback system.
Jenny Dip fell off her motorcycle and tore a nerve in her axillary region. She also tore ligaments in her cervical and scapular regions and broke the only bone of her right brachial region. Explain where each of her injuries is located.
She tore a nerve in her armpit as well as ligaments in her throat region and shoulder blade area. Also broke her upper right arm bone.
Virtually no chemical reactions can occur within the body in the absence of enzymes. How might excessively high body temperature or acidosis (acidic blood pH) interfere with enzyme activity?
High temperature and acidosis will harm enzymes which will stop them from being able to to do the job that they are needed to do and can't be done without those enzymes.
Define monosaccharide, disacchharide and polysaccharide and give an example of each. Which of these is the building unit of carbohydrates, and what is the primary function of carbohydrates in the body?
Monosaccharide - simple sugar ex. glucose
Disaccharide - double sugar ex. sucrose, maltose
Polysaccharide - long chain of monosaccharide ex. starch
A monosaccharides are the building units of carbohydrates, carbohydrates act as road signs to guide cellular interactions
The epidermis of the skin is made up of stratified squamous epithelium. Explain why this type of epithelium is much better suited to protect the body's external surface than a simple columnar epithelium.
A simple squamous has many more layers than simple columnar. so therefore it takes a more serious or deeper injury to reach an inside level of body or other tissue.
Lupus is a disease that causes inflammation of the connective tissue. Would a person who has lupus most likely experience localized symptoms or widespread symptoms? Explain why.
Someone with lupus should experience widespread symptoms such as swelling. This is because connective tissue is the most widespread tissue type so it is most likely to happen multiple times than just once.
