How can the freezing of surface waters make the water that is left unfrozen denser

Biology

Explanation:

When an aqueous solution freezes, the unfrozen solution becomes denser. That's because some of the water has been removed as ice. However, the solutes remain dissolved in a solution with a smaller liquid volume. The concentration of the solution increases, so the density increases.

this is because water expands as it gets cold hence floating leaving the unfrozen water dense

The theory of endosymbiosis suggests that chloroplasts and mitochondria were once free-living prokaryotes, that were engulfed by
Drupady [299]

The question is incomplete. The rest of the question is : Which of these is not supported by the endosymbiosis theory concerning organelles?

A) contain DNA.

B) contain ribosomes.

C) are capable of living independently.

D) are surrounded by a double membrane.

Answer:

Option C) are capable of living independently  is not supported by the endosymbiosis theory concerning organelles

Explanation:

The endosymbiosis theory proves that chloroplasts and mitochondria were prokaryotic cells before due to many reasons. Some of which are:

  • These organelles have their own separate DNA.
  • The separate DNA present in them is capable of making their own proteins.
  • They are membrane- bound organelles.

However, these organelles can now not live separately outside of the cell. This might be because of the evolutionary changes which  occurred in these cells during the long period of time.
