<h2>Scurvy </h2>
Explanation:
(a) Collagen is the major structural component of cartilage,bones and tendons
- The basic unit of collagen is tropocollagen and each tropocollagen consists of three coiled left handed polypeptide chains called α chains
- Generally each α chain consists of a repeating tripeptide sequence called: G-X-Y
- Here G represents glycine; X represents proline and Y represents hydroxyproline
- Rigidity of collagen molecule is due to presence of proline and hydroxyproline
- Hydroxylation of proline is catalysed by prolyl hydroxylase enzyme which use ascorbate,α ketoglutarate and oxygen
- α ketoglutarate is oxidatively decarboxylated to form carbon dioxide and succinate
- Sequence of events leading from a dietary vitamin C deficiency to symptoms such as bruising and breakdown of supporting tissues includes: tissue levels of ascorbic acid is low; enzyme prolyl hydroxylase is inactive; proline is not hydroxylated; the triple helix is inadequately stabilized; collagen breaks down; defects in tissues that depend on collagen
; tissues that depend on collagen are subject to breakdown and bruising
(b) Sailors are no longer susceptible to scurvy because fresh fruits which are the source of vitamin C source are available now
British sailors called "limeys" to this day,this term reflects the British navy's use of limes

Answer:
The central nervous system (CNS) controls most functions of the body and mind.
i think this is it
Explanation:
Answer:
Rapid progress in biomedical science has also encouraged the development of multiple successful medical technologies, but their translation into clinical use has posed complex scientific, cultural, and social problems. As demonstrated by the development of new acquired immune deficiency syndrome (AIDS) medications, the rise of these problems is spurring new interest in medical innovation.
Biomedical products are created for better results in medical technology including autoclave / sterilizer, anesthesia machine, aspiration/suction pump, and blood chemistry analyzer etcetra.
Factors influencing them includes harmful effect on other body parts ( beta blockers have harmful effect on heart), outdating technology, and introduction of evolved diseases that is not abl to cure with old products.
In meiosis the are two divisions. The division of the original cell results in two daughter cell. Those two cells divide to produce 4 haploid cell in total.
