What physical change occurs quite frequently in middle-aged men?
Oliga [24]

Answer: A) Balding

Explanation:

Balding is the most common pshysical change in middle-aged men.

Generally speaking, men between 35 and 40 years old develop a state of baldness that although it is not aggravated, it is notorious. Some men even begin to lose their hair at an earlier age, approximately 25 years old and older, although in those cases it is very likely that the cause is a genetic tendency.

Normally, after a certain age range (stated above) the hair fiber begins to lose strength and said follicles simply do not allow hair growth so fast as they did when the individual was younger.

Choose the structures that most directly provide nutrients and remove wastes from osteocytes in compact bone.
Ber [7]
I had to look for the missing options of this question and here is my answer:

Osteocyte is the term that describes the cells of the bone. These cells are formed in the mesenchyme. Once the bone matures, the processes then take place inside the Lacunae and the Canaliculi, respectively. Therefore, we can say that the structure that allows the provision of nutrients and removal of wastes from osteocytes would be the canaliculi.
