Answer:

I would think it’s the long distance runner.

Explanation: Running at any significant distance requires tremendous exertion from the entire body and breathing properly is the key to getting enough oxygen into the bloodstream which then carries it throughout the body.

Identify one possible air pressure at the center of the low-pressure system.
sineoko [7]

High in the atmosphere, air pressure decreases. ... A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation.

Select the letter of the correct answer.
ZanzabumX [31]

Answer:

3.5264 x 10^{7}

Explanation:

The metric ton is used as a unit of mass. The metric ton in British units can be represented as 2240 pounds or long ton whereas in United state is termed as 1.102 short ton.

In the given question, it has been mentioned that the growers around the world produce about 3.2 x 10^{7} a metric ton of sunflower.

So the short ton produced will be

= ( 3.2 x 10^{7} ) x 1.102

= 3.5264 x 10^{7} short ton.

Thus, 3.5264 x 10^{7} is the correct answer.

What is a non example of crystallization​
schepotkina [342]

Answer:

Microscopically, a single crystal has atoms in a near-perfect periodic arrangement; a polycrystal is composed of many microscopic crystals (called "crystallites" or "grains"), and an amorphous solid (such as glass) has no periodic arrangement even microscopically.

Most inorganic solids are not crystals but polycrystals, i.e. many microscopic crystals fused together into a single solid. ... The third category of solids is amorphous solids, where the atoms have no periodic structure whatsoever. Examples of amorphous solids include glass, wax, and many plastics.

In condensed matter physics and materials science, an amorphous (from the Greek a, without, morphé, shape, form) or non-crystalline solid is a solid that lacks the long-range order that is characteristic of a crystal. In some older books, the term has been used synonymously with glass.

Explanation:

This chapter highlights mesocrystals as an interesting example of particle‐mediated, non‐classical crystallization processes. Mesocrystals — the shortened name for mesoscopically structured crystals — are superstructures composed of nanoparticles, being arranged three‐dimensionally in crystallographic register. Mesocrystals are often only intermediate structures in a non‐classical crystallization pathway leading to a final single crystal by nanoparticle fusion. Therefore, they are difficult to detect. Although mesocrystals were initially described for synthetic systems, recent investigations have revealed an increasing number of bio‐mineral systems which appear to be mesocrystals, but which so far have been considered to be single crystalline, including nacre and sea urchin spines. This chapter briefly defines non‐classical crystallization processes, provides some examples of synthetic mesocrystals and mesocrystals in biomineralization, and attempts to provide some insight into their formation mechanisms, despite their being as yet largely unexplored.
