Water is able to dissolve varieties of all kinds of different substances, which is the whole reason why it's such a good solvent.
It's also called the "universal solvent" bcuz it dissolves more substances than any liquid has ever been able, and this allows the water molecule to become attracted many other kinds of molecules :)
Glad I could help! Byee
In the 1900s, Comparative Biologists were based in North America, while Ethologists were based in Europe. Hope that help!
Choice A:
A male inherits only one of the two X-linked genes controlling hair color.
The correct answer is an increased number of rod cells.
In eyes of the humans, and many other animals there are two types of receptors, the rods, and the cones. The cones have an important role in color vision and they possess different types of pigment which enable color vision.
On the other hand, the rods are more sensitive to light, and they are responsible for black and white vision.
Therefore, an increase in the number of rods can enable the animal to see betther in the dark.
