The proximate reason for the uptake by plants of nutrients like ammonium nitrate is?
Blizzard [7]

The proximate reason for the uptake by plants of nutrients like ammonium nitrate is homeostatis

<h3>What is homeostasis?</h3>

Homeostasis refers to an organism's ability to regulate various physiological processes to keep internal states steady and balanced.

<h3>How does plant perform homeostatis?</h3>

As water leaves the plant tissues into the atmosphere, it takes energy with it in the form of heat.

Much like when we sweat, this allows the plant to cool and maintain homeostasis.

Similarly, the same process allows plants to  absorb nutrient like ammonium nitrate.

Thus, the proximate reason for the uptake by plants of nutrients like ammonium nitrate is homeostatis.

Which material is likely to slow the<br> flow of electric charges the most? Explain.
AlladinOne [14]

Explanation:

Atoms of metals do not hold their electrons to themselves. Instead they allow them to float around them delocalised. This is important because it is this characteristic that allows metals to be good conductors of electricity since electrons are free to move around to carry a charge.

Why is there Roman numerals (II) in copper(II) chloride, but no (III) in Aluminum chloride?
Neporo4naja [7]

This is because copper is a transition metals.

Transition metals don't have a definite charge, you can see this on the periodic table. However, Alkali Earth, Alkali, Metalloids, Non-metals, Halogens, Noble Gases, etc, all have a specified charge.

Although, there are exceptions: Zinc, Gold, and Cadmium.

Aluminum is a poor metal, but it has it's own charge (3+).

Therefore, Copper has roman numerals due to the fact that it's a transition metal and Aluminum is a poor metal.

Hope this helps!
