The calcium get into your body through Vitamin D.
<u>Explanation:</u>
In order to make the bones healthy, calcium and phosphorus is very essential. Calcium cannot be made by human body. The body only gets the calcium it needs, by means the food you eat, or from supplements. Vitamin D plays a major role in the absorption of calcium in human body. Calcium is a major mineral in a human body that helps in the proper working of body cells and nerves.
The quantity of the minerals like calcium, phosphorous,etc that are present in a segment of bone determines the density of bone. A percentage of 15 to 20 of calcium is absorbed from the diet that human intake. When the levels of vitamin D is low, there will be lower intake to calcium by gut. This causes the bones to become weaker.

Answer:
3' to 5'; 5' to 3'
Explanation:
The DNA strand with 3' to 5' polarity serves as a template for the process of transcription. Using the 3' to 5' DNA template strand, the enzyme RNA polymerase catalyzes the formation of RNA. The ribonucleotides are bonded together by phosphodiester bonds that are formed in 5' to 3' direction only. The formation of RNA occurs in 5' to 3' direction. The DNA template strand has a complementary nucleotide sequence to the newly synthesized RNA.
Van Leeuwenhoek discovered "protozoa" - the single-celled organisms and he called them "animalcules". He also improved the microscope and laid foundation for microbiology. He is often cited as the first microbiologist to study muscle fibers, bacteria, spermatozoa and blood flow in capillaries.
