the freezing point was denser than the water at 4°C?
a)The water would freeze across the surface of the lake, blocking sunlight necessary for photosynthesis.
b) The water would freeze across the surface of the lake, blocking the dissolving of oxygen and nutrients.

The correct option is D.
If water density at freezing point is greater, the ice formed will sink to the bottom of the water body and freeze the water up from the bottom. This will surely lead to the death of everything that live inside the water.

What is the primary objective in a telescope? What two materials can it be<br> made of?
Dennis_Churaev [7]

Answer:

The objective itself is usually a cylinder containing one or more lenses that are typically made of glass; its function is to collect light from the sample.

Explanation:

A telescope mirror can be made from glass that is somewhat less pure than that used to make a lens, since light does not pass through it.
