How to find solvent?

Biology
1 answer:
Helen [10]3 years ago

Answer:

here

Explanation:The concentration of a solution can be given in moles of solute dissolved per kilogram of solvent.

This is known as molality.

(Not to be confused with molarity which is a different measure of concentration.)

Molality is given the symbol m.

molality = moles of solute ÷ mass of solvent in kilograms

m = n(solute) ÷ mass(solvent in kg)

A solution containing 3 moles of solute per kilogram of solvent for example, is said to be 3-molal or 3m.

Hello, people of planet earth, I need help with a question for my friend Steve in science class, here on planet Neptune it is pr
ICE Princess25 [194]
The paramecium has two nuclei, a big and small one. The big one operates as the director of the cell's activities, rather like a little brain. The smaller one is used for reproduction. The paramecium splits in half (fission) just as the ameba does. First the smaller nucleus splits in half and each half goes to either end of the paramecium. Then the bigger nucleus splits and the whole paramecium splits. Occasionally two paramecium exchange material and form a new paramecium. This is called conjugation. 

<span>Conjugation in Paramecia occurs in the following way: </span>

<span>a). The formation of ciliary contacts. </span>
<span>b). Local loss of cilia and formation of narrow contacts between anterioventral somatic cell membranes </span>
<span>c). Formation of small cytoplasmic bridges (which allow for the exchange of molecular components only). </span>
<span>d). Their enlargement enables the cells to exchange micronuclei. </span>

<span>Bacteria exchange plasmid material and the Paramecia exchange micronuclei.

Good luck to Steve! How is it in Neptune? XD</span>

1. About of all species on Earth<br> have become extinct.<br> 10%<br> 50%<br> 99%
natulia [17]

Believe it or not, 99.9% of the species on Earth have gone extinct. Now, not all of these were caused by Humans, some were caused by MAJOR cataclysmic events such as the extinction of dinosaurs or other prehistoric animals that make up a large amount of the species on Earth. And remember that all the prehistoric plants are also included, because every plant organism is ALSO a species.

Hope this helps, if not, comment below please!!!
