A The observed differences in plants height are due to genetics.
The concentration of lipids necessary to prepare liposomes with a diameter of 250 nm is 0.30 mM.
<h3>What are liposomes?</h3>
Liposomes are vesicles which are made up of a lipid bilayer membrane.
Liposomes are important as delivery vehicles for substances such as drugs.
Ultrasonication is a method of liposomes preparation.
Solution of liposomes is dependent on the size.
The larger the diameter, the smaller the l elution volume. Also, increasing lipid concentration will decreases elution volume.
Therefore, the concentration of lipids necessary to prepare liposomes with a diameter of 250 nm is 0.30 mM.

The speed of a sound wave depends upon the medium through which it travels. In general, sound travels faster through solids than through liquids or gases. Also, the denser the medium, the slower sound will travel through it. The same sound will travel at a different speed on a cold day than it would on a warm day.
The soil, fertilizers, and pesticides eroded by the surrounding waterways are transported via the water to a location different from their former one. These are taken away by the water flow and deposited in the delta area of the river. This delta is a land-form which is formed by the deposition of the similar substances, where the flow of the river is slower.
Hence, the correct answer is 'Option B'.
