Elden [556K]
Type-II Diabetes, or non insulin-dependent diabetes mellitus (NIDDM) involves a disrupted insulin signaling mechanism [broken]. There is usually a problem with insulin receptors on cells, and not so much the insulin itself (or pancreas). Sometimes the cause of type-II is referred to as "insulin resistance."

if you examined a cross section of a eudicot plant stem, in what order would you encounter different plant tissues from the pith
SSSSS [86.1K]

From the pith outward, if you looked at a cross-section of a eudicot plant stem, you would see Xylem, vascular, cambium, and phloem in that order. The vascular cylinder divides the ground tissue into two discrete areas and is structured in a ring in eudicot stems.

The pith refers to the area of ground tissue that is included within the vascular cylinder. In general, eudicots possess three or more of the following traits: There are 2, 4, or 5 flower parts, or multiples of 4 or 5, and leaves have netted venation (pinnate or palmate). A ring of stem vascular bundles surrounds the pith, and seeds have two seed leaves (cotyledons).

As a result, we can assert that if you cut a cross-section of a eudicot plant stem, Xylem, vascular, cambium, and phloem in that order, you will find various plant tissues from the pith outward.

A plant cell is placed in distilled water, as shown in the figure. There is a net uptake of water by osmosis, causing the cell t
Korvikt [17]

Answer:

The water potentials (Ψ) of the cell and its surroundings are the same.

Explanation:

When a cell is kept in hypotonic surroundings such as distilled water, the osmotic movement of water occurs towards the cell. The entry of water makes the cell swell up and it becomes turgid. Water potential is determined by solute and pressure potentials mainly. Here, the solute potential of the cell and the distilled water was different resulting in differences in their respective water potential values which in turn served as a driving force for endosmosis.

When the cell is fully turgid, the solute concentration of the cell and the surrounding distilled water become equal to each other. Under these conditions, the water potential of the cell and distilled water are the same.
