Answer:
Maltose
Explanation:
Maltose consists of two molecules of glucose that are linked by an α-(1,4′) glycosidic bond. Maltose results from the enzymatic hydrolysis of amylose, a homopolysaccharide (Section 26.9), by the enzyme amylase. Maltose is converted to two molecules of glucose by the enzyme maltase, which hydrolyzes the glycosidic bond. Commercial maltose is produced from starch that has been treated with barley malt.
The monosaccharide unit on the left is the hemiacetal of the α-d-glucopyranosyl unit. It is linked by an α-(1,4′) glycosidic bond to β-d-glucopyranose, the aglycone. The oxygen atom of the glycosidic bond is approximately in the center of the structure, between the two rings. It is projected down, axial, and therefore α. It is linked to C-4 of the aglycone, and so the link is axial–equatorial.
Maltose has a more formal, IUPAC of name: 4-O-(α-d-glucopyranosyl)-β-d-glucopyranose. This rather forbidding name is not quite as bad as it looks. The term in parentheses refers to the glucose unit on the left, which contributes the acetal portion of the glycosidic bond. The term -pyrano- tells us that this part of the structure is a six-membered ring, and the suffix -osyl indicates that the ring is linked to a partner by a glycosidic bond. The prefix 4-O- refers to the position of the oxygen atom on the aglycone, the right-hand ring. The term β-d-glucopyranose describes the aglycone.
Because the aglycone is a hemiacetal, maltose undergoes mutarotation. For the same reason maltose is a reducing sugar. The free aldehyde formed by ring opening can react with Benedict’s solution. The acetal part of the structure is called the “nonreducing end” of the disaccharide. If we do not want to specify the configuration of the aglycone, we use the name 4-O-(α-d-glucopyranosyl)-d-glucopyranose.

Explanation:
The Diaphysis ossifies before the other portions.
This is the middle of a section of thick, compact long bone. It comprises the main shaft and is typically cylindrical or tube-like in appearance. It functions as structural support and contains bone marrow, which produces red blood cells, white blood cells and platelets; it also contains adipose or fat tissue.
Osteoids comprise, significant sections of the entire bone matrix, and this includes fibers of collagen which give bone its flexibility and mechanical strength this allows born to resist stretching and twisting forces.
Osteoblasts are highly specialized cells which formulate new bone through the production or secretion of parts of the organic matrix; this is referred to as the osteoid and mediate the calcification of osteoid during the formation of mature bone matrix. The diaphysis is produced through the ossification of stem cells or mesenchymal cells during early development. Primary ossifiation occurs at ossification centers at the diaphysis, from cartilage cells in the matrix.

Answer:
Astigmatism is a problem of how the eye focuses light typically caused by a defect in the lens, resulting in distorted images. Astigmatism is not an eye disease or health problem. While it can cause blurred vision, eye strain, and headaches, particularly after prolonged reading, it does not cause blindness.
Astigmatism can be corrected with glasses, contact lenses, or refractive surgery (i.e. laser eye surgery), although treatment may not be necessary if the symptoms are mild. Glasses and contact lenses both compensate for the irregular shape of the cornea and help to focus light properly into the back of the eye
Answer:
Hypotonic solution
Explanation:
Haemolysis of red blood cell refers to the destruction or breakdown of red blood cells. Red blood cell will undergo haemolysis if placed in an Hypotonic solution. Hypotonic solution is a solution that contain smaller amount or lower concentration of solutes like dissolved salt than other solution and also compared to the cystol. If a cell is placed in Hypertonic solution, red blood cell will swell because it will absorb solute and undergo hemolysis burst when placed in a hypotonic solution.
