five minutes and after forty-five minutes can be observed, as the ratio of lipids and carbohydrates vary depending on the time of the race. Due to the different energy densities and the body’s varying abilities to oxidise glucose, they dominate over each other at different times during the race as they are the most dominant energy source. Energy is also produced for the synthesis of adenosine triphosphate (ATP), through the catabolism of carbohydrates and…

1. Describe the function of the scrotum in protecting the testes from temperature fluctuations. Scrotum is an external sex organ. The scrotum is a pouch like structure made up of skin. It has 2 main functions. It protects the testis and maintains 2-3oc temperature lower than body temperature, which is very important for spermatogenesis.

Sometimes you need something to represent you, say a team. But you don’t have anything. I made a crest to symbolize myself. Three things I but on my Crest are symbols, values, and a motto.

The key means I can open up new paths for myself and choose where I want to go. The bow means I am watchful from afar. The arrow means me watching can’t always be a good thing. Next up…

Mosquitoes will think they hit the jackpot when they find a ripped screen to come through. If you don't want to be a…

The team leader for this experiment was Kyle McClain. Zach Verlander was supposed to be the recorder for this lab, but since he dropped the class I took his place as the recorder for the experiment. Greg was in charge of the backside of the heat exchanger apparatus, while Kyle controlled the front side of the apparatus. Greg monitored the pressure gauge of the steam inlet and measured the steam inlet temperature off of the temperature gauge. Kyle used the thermocouple meter to read the pressure…

Bad Boy Vibes by H.M Irwing is a thrilling trilogy that is made up of three books; Heartaches, Heartaches 2 and Heartaches 3. I was tempted to refer to this series as a triangle of books.
