In adults, vitamin D deficiency leads to osteomalacia, which causes weak bones, bone pain and muscle weakness.
The body needs vitamin D to properly absorb calcium and phosphorus from the diet. However, keeping the right quantities of calcium and phosphorus in bones is challenging when vitamin D levels are low.
The two sources of vitamin D are-
- Natural sunlight
- Foods such as fish oil, Egg yolk and fatty fishes like salmon and mackerel
There are other disease conditions which lead to poor absorption of vitamin D-
- Inflammatory bowel disease

Semen creates a(n)<u>alkaline </u>environment for sperm to safely travel through both the male and female reproductive tracts.
In the field of biology, semen can be described as a white, slippery fluid that is released from the male reproductory organ. Semen is also referred to as the seminal fluid.
The semen of males carries the sperm cells which are required for the fertilization of the female egg. The conditions should be favorable for the process of fertilization to occur.
The natural atmosphere of the vagina of a female is acidic in nature. The sperms need a neutral environment for survival. Hence, the semen is produced alkaline in nature to prolong the lifetime of sperm cells. The alkalinity of the semen neutralizes the acidity of the vagina.
