Xylem is one among the two types of transport tissue in vascular plants, the opposite being phloem.
Transport water from roots to stems and leaves is the main function of xylem, but it also transports nutrients.
The word xylem springs from the Ancient Greek word ξύλον (xylon), meaning "wood"; the best-known xylem tissue is wood, though it's found throughout a plant. The term was introduced by Carl Nägeli in 1858.
The long tracheary elements are the most distinctive xylem cells that transport water. Tracheid and vessel elements are distinguished by their shape; vessel elements are shorter, and are connected together into long tubes that are called vessels.

Give an example of antagonistic control

kozerog [31]

<h2>Antagonistic Control</h2>

Explanation:

These cells control blood glucose focus by creating the <em>hostile hormones insulin and glucagon Beta cells</em> <em>discharge insulin</em>.
When the convergence of blood <em>glucose drops (during exercise, for instance), alpha cells emit glucagon</em> into the blood.
<em>Glucagon </em>animates the liver to discharge <em>glucose. </em>
The opposing control issue isn't curved, thus can't be effectively fathomed. We present here an incredible arched streamlining based heuristic for opposing control, in view of the <em>curved inward system.</em>
Most pessimistic scenario, inputs. We additionally give a<em> S-methodology </em>based upper headed for opposing control, pertinent in situations when the goal and requirements can be depicted by quadratic imbalances, and utilize this to confirm on models that our strategy yields inputs exceptionally near the<em> (worldwide) thinking pessimistically.</em>

Describe the differences in the four protein structures.

hram777 [196]

Answer:

The four levels of protein structure are distinguished from one another by the degree of complexity in the polypeptide chain. A single protein molecule may contain one or more of the protein structure types: primary, secondary, tertiary, and quaternary structure.
