Which observation provides evidence that a cell is most likely a prokaryote
Otrada [13]

Answer:

it has dna that is not contained within a nucleus

Explanation:

The word prokaryote is of Greek origin and means “anterior nucleus” or “before having nucleus”. This meaning gives the impression that it is a primitive structure, and that is exactly what these organisms are about. When compared to eukaryotes, prokaryotic cells are simpler, which leads to the belief that they are more primitive elements in evolutionary history. Thus, it is believed that the first cell was that of a prokaryote being.

The composition of this cell group has few membranes, in general, the only one present is the one that delimits the cell. The prokaryotic cell is characterized by the absence of very well-known and common membranous organelles, such as mitochondria, chloroplast, Golgi complex and nucleus. Regarding the absence of a nucleus, the DNA of this cell is not separated from the cytoplasm by a nucleus.

The prokaryotic cell has a plasma membrane, cytoplasm, free and non-compartmented genetic material (DNA) and ribosomes.

At 95% humidity, what percentage of the air around us is water vapour? Can you drown? ...?
NISA [10]
Humidity<span> is the amount of </span>water<span> vapor in the air. </span>Humidity<span> varies from place to place and season to season.

</span><span>There are two types of Humidity:
Absolute Humidity and Relative Humidity.
 
Absolute Humidity is the weight of water vapor in a cubic meter of air. The higher the temperature, the higher the ability of air to hold water. For example, at 20 C, the maximum Absolute Humidity is 17.3 g/m^3. At 50 C, the maximum Absolute Humidity is 83.0 g/m^3.  Relative Humidity is the % of water vapor in the air relative to the maximum possible Absolute Humidity.</span><span>

</span><span>When we use the word Humidity in ordinary speech, we're talking about Relative Humidity. So,  if the humidity is 95% or even 100%, that doesn't mean 95% or 100% of the air around us is water vapor; just the amount of water in the air is 95% or 100% of the maximum it can hold. 
</span>
Therefore, we wouldn't drown at 95% humidity, we will be uncomfortable due to the heat content of air and water but we are still be able to breathe. I hope this answer helps.

The stage of mitosis where the chromosomes line up
schepotkina [342]

Answer:

Metaphase

Explanation:

Chromosomes line up at the metaphase plate, under strain from the mitotic shaft. The two sister chromatids of every chromosome are caught by microtubules from inverse shaft posts. In metaphase, the shaft has caught every one of the chromosomes and arranged them at the center of the cell, prepared to separate.
