Answer:
These islands are barrier islands.
Explanation:
Barrier islands are islands in front of the mainland that separate part of the sea from the open sea. They lie parallel to the coast and have an elongated, narrow shape. On the sea side, dunes often shape the surface, on the land side they are flat. They were created by deposits of waves, currents and wind. Their formation requires a shallow coastal fore, a sufficiently large sediment store and a weak to moderate tidal range.
Oh this is easy.
Astronomy is the branch
<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
The last option: over tens of millions of years, the giant supercontinent Pangaea began to slowly drift apart forming the continents
<h2>
Animals</h2>
Explanation:
A. Animals have muscle tissue, whereas other living things do not.
The character that contrasts animals with other living organism is the presence of muscle tissue. Muscle tissue is exclusively found in animals and are not found in any other kingdom of the living world.
Animals and many other living things posses multiple cells. Most of the cells in organisms are with nucleus.Most of the multicellular organisms have tissue level organization of the body.
