Answer: a. use of refrigerated clotted blood samples in which complement components coat RBCs in vitro
Explanation:
DAT is direct antiglobulin test. It is also called as Coombs test. It is primarily used for determining the cause of hemolytic anemia. This test looks for the attachment of the antibodies that break apart the red blood cells causing hemolysis.
A false positive DAT result signifies that the eluted antibody cannot bind to the red blood cells. But binding do occur in true positive test.
Thus the result may reflect that it has been conducted on the refrigerated and clotted blood samples yielding a false result in inappropriate results.
No; of course not! When you play a sport, whether you lose or win does very little compared to how you play and treat others. If you win, and tell another player they did horrible, or bring them down mentally in any way, you are being a poor sport.

Explanation:
The testes are where sperm are manufactured in the scrotum. The epididymis is a tortuously coiled structure topping the testis, and it receives immature sperm from the testis and stores it for several days. When ejaculation occurs, sperm is forcefully expelled from the tail of the epididymis into the deferent duct. Sperm then travels through the deferent duct through up the spermatic cord into the pelvic cavity, over the ureter to the prostate behind the bladder. Here, the vas deferens joins with the seminal vesicle to form the ejaculatory duct, which passes through the prostate and empties into the urethra. When ejaculation occurs, rhythmic muscle movements propel the sperm forward.
