Answer:

Pili

Explanation:

The first external structure is the pilus (plural: pili). A pilus is a thin, rigid fiber made of protein that protrudes from the cell surface. The primary function of pili are to attach a bacterial cell to specific surfaces or to other cells. But how does the pilus know exactly what surface to attach to? Along the length of the pilus are adhesin proteins. The word 'adhesin' should remind you of the word 'adhesive' These molecules aid in the attachment of the pilus and are specific to the target surface.

Bordetella pertussis is the bacteria that causes whooping cough. Bordetella has pili coated with adhesins that can identify the mucosal surface of the respiratory tract and will stick to only that surface, allowing it to adhere to and infect those cells.

Plants have some of the most of complex cells of living organisms because they have different roles and structures to enable the plant to survive.

These include cells like the Parenchyma, Collenchyma, Sclerenchyma, Xylem and Phloem cells. Xylem cells for instance are complex cells located within the vascular tissues of plants and help transport water and minerals to the rest of the plant from the roots. Xylem cells look long and tracheal which is to enable them carry out the aforementioned roles.

Answer:

c. Increased reabsorption of phosphate in the kidneys

d. Increased deposition of calcium into the bones.

Explanation:

Hyperphosphatemia is a condition that is expressed particularly in people with a kidney dysfunction. It comprises the kidneys, which do not excrete enough phosphate from the body as they reabsorbe it and thus leading to increased phosphate levels.

Also, phosphate binds calcium with high affinity, provoking acute hypocalcemia (decreased levels of calcium). In Hyperphosphatemia, calcium is being deposited mostly in the bone but also in the extraskeletal tissue.
