What do each of the three male glands contribute to semen?
The 3 male glands are: 1. seminal vesicles 2. prostate gland 3. bulbourethral glands (Cowper's glands) Seminal vesicles make a gooey liquid rich in sugars, producing about 60% of the volume of seminal fluid in the body. The prostate gland secretes an antacid liquid. The bulbourethral organs discharge thick, gooey, antacid bodily fluid that acts as lubrication.
A student was isolating copper metal from a copper salt. If the student started with 1.255 g of Copper II sulfate, how many grams of copper solid would you expect them to recover ?
First step is to calculate the molar mass of CuSO4 by adding up the values of each element from the periodic table. This gives us - 63.5 + 32 + (16x4) = 159.5 g/mol. For each mole of CuSO4, there is a total of 159.5 grams. Of the 159.5 grams, 63.5 are from copper. This as a percentage would be 63.5/159.5 = 39.8% To find out how much copper is in 1.255 g, we take that percentage and multiple by what we have: .398*1.255 = 0.5 grams To do it in one step: 63.5/159.5 x 1.255 = 0.5 grams
What is the path of protein transport through the cell?
Protein transport starts at the ribosomes. They send the proteins to other structures in the cell - including the endoplasmic reticulum & Golgi bodies where the proteins are changed & packaged. Each of these organelles have a role in helping these proteins reach their final destination.
