You observe a tiny structure under a microscope.what question would ask and then investigate to determine whether the structure
anygoal [31]

Answer:

The question to be asked an investigated when observing a structure under the microscope to determine whether it is living is if it has a nucleus if eukaryote or nucleoid if prokaryote.

Explanation:

The major organelle that must be present in all living cells is the nucleus or nucleoid and the protoplasm. The observation of the cell under the microscope will show the subcellular entity, nucleus/nucleoid, more pronounced than other organelles in the cell. The nucleus house the necessary information for the maintenance and reproduction, which is mainly the genetic information that dictates the translational protein products that are needed to build another aspect of the cells. Therefore, when such a tiny structure is placed under the light microscope under the view of oil immersion, the nucleus of the cell should be visible if it is a living structure.

Would white fur color be an evolutionary advantage if the arctic circle began to resemble a temperate forest biome?
Firdavs [7]

Answer:

White fur is only an evolutionary advantage if the creature can hide in snow.

If you live in a temperate forest biome and want to hide from enemies, you wouldn't want fur that sticks out brightly against the dark forest.

Just like, if you lived in a snowy biome, you wouldn't want black fur that would stick out against all the snow.

So no, white fur is not an evolutionary advantage in a temperate forest biome

Hope this helps!
