Tcecarenko [31]

Among the typical midlife changes for men is an Increase in prostate size.

A portion of the fluid that carries sperm during ejaculation is produced by the prostate, a gland. The urethra, which is the tube through which urine leaves the body, is surrounded by the prostate gland.

As you get older, your chances of having an enlarged prostate go up. Because BPH is so common, it has been said that if a man lives long enough, he will all have an enlarged prostate. Many men over 40 have a small amount of prostate enlargement. The condition affects more than 90% of men over the age of 80.

How does cellular respiration demonstrate<br> the conservation of mass?
Nonamiya [84]

Cellular respiration is the process by which cells obtain energy from glucose. It can be represented by a chemical reaction which, when balanced, obeys the Law of Conservation of Matter:

C6H1206 + 6O2 ---- 6CO2 + 6H2O

Th number of atoms of reactants equals the number of atoms of products:

six carbon atoms, 12 hydrogen atoms, 18 oxygen atoms

No atoms are created or destroyed in this process, they're just rearranged into different molecules.

We often hear the term "burn" to describe glucose being used by living things for energy. When a substance burns, matter is conserved. It might seem like the burned substance is completely consumed because the products, CO2 and water, are both produced in the gaseous form and are colorless and invisible. The French chemist Antoine Lavoisier was the first to show that mass is conserved in chemical reactions by carrying out combustion reactions in a closed system and capturing the gaseous products.
