Answer:

c. ll and lll only

Explanation:

Algae are plant-like protists capable of photosynthesis in their cells (chloroplast). Like every other living organism that grows and reproduce, algae also requires nutrients for these processes to effectively occur.

Algae makes use of inorganic nutrients including sulphates, phosphates, nitrates etc which are found in fertilizers, detergents etc. In the presence of these compounds, algae tends to grow excessively to form a BLOOM. Hence, according to the question, nitrates and phosphates are the two inorganic nutrients algae makes use of.

A train travels at a speed of 30 miles per hour. If 1 mile = 1.6 kilometers, how fast is the train traveling in kilometers per m
Alina [70]
The answer 
 the speed of <span>the train traveling in kilometers per minute can be found by using the following method:
v = </span><span>30 miles per hour
</span><span>1 mile = 1.6 kilometers

just do the calculus by changing miles to kilometers
 </span>1 mile = 1.6 kilometers, so 30 miles= 1.6 km x 30 = 48 km
 so the speed of the train is
v=30 miles / hour = 48km / h = 48km / 60 mn  = 0.8 km/ mn
the answer is
<span>C- 0.8 km/min</span>

Nickel(ii) chloride dissolves in water to form a light green solution. what ions are present in solution—that is, what is "swimm
ArbitrLikvidat [17]

Hello!

The ions that are present in solution are Ni⁺²(aq) and Cl⁻(aq)

Why?

When an ionic substance like Nickel Chloride (NiCl₂) dissolves in water, it dissociates into the individual ions that form the substance. Water molecules surround then the individual ions in a process called solvation.

It can be represented in the following chemical equation:

NiCl₂(s) → Ni⁺²(aq) + 2Cl⁻(aq)

Have a nice day!
