<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:
3 criteria used to determine whether is REAL SCIENCE are temperature, precipitation and atmospheric pressure
Explanation:
Temperature forms the basis of a weather condition, it depicts the role of some other criteria, other factors are precipitation and atmospheric pressure
I think that's asexual reproduction.
<span>The answer would be: less; less
Repetitive Transcranial Magnetic Stimulation(</span>rTMS) and Electro Convulsion Therapy(ECT) are a treatment option for a patient with major depressions. Both of them is dangerous because it involves a stimulation of the brain and has a chance to do permanent damage afterward. rTMS is a newer method that has lower chance of side effect.
