Ateenager presents to the clinic with an infected wound from a bike accident. he asks, how does my body fight off the germs in my scraped arm? which is the nurse's best response? the cells that plays the central role related to the innate immune response to an infectious microorganism are:
a. t lymphocytes.
b. antibodies.
c. b lymphocytes.
d. neutrophils.

Really, none of these answers are good. leukocytes are the body's general immune cell, and lymphocytes are a type of leukocyte. Antibodies are only used when fighting an infection that your body already has experience with, so I'm guessing it you have to pick from these answers, its "lymphocytes", but it's not really the best answer.

The mass of 220 lb football has less than 288 lb football. So, it will be easier to move it since it will require less force. The heavy football will have a bigger momentum. Since 288 lb has more weight than 220 lb, it will have bigger inertia making it difficult for the players to stop it. This makes it easier to tackle 220 lb football than 288 lb football.
