Answer:
A is a eukaryotic cell while B is a prokaryotic cell
Explanation:
The researcher can conclude that <u>cell A is eukaryotic while cell B is prokaryotic.</u>
In eukaryotic cells, the <u>DNA is located majorly in the nucleus and the replication of the DNA happens in the nucleus</u>. Hence, it is only logical to find segments of new DNA in the nucleus of cell A during replication.
<u>Prokaryotic cells, however, lack a nucleus</u>. Their DNAs lie freely within the cytoplasm. This thus means that replication can only happen in the cytoplasm. Hence, it follows logically to find a new DNA segment in the cytoplasm of cell B.
Answer: When you mix sand and water there are no reactions. The sand sits at the bottom of the water because the sand is heavier than the water is.

Answer:
Ability to perform locomotion with their legs
Explanation:
Plants and animals are two distinct species of organisms. Plants are capable of using photosynthesis to obtain their food due to the unique structures that can capture light energy in their cells (autotrophic). Animals, on the other hand, are heterotrophic i.e. cannot perform photosynthesis and therefore, rely on other organisms for food.
Since animals depends on eating other organisms to obtain food/energy, their possession of LEGS or ability to LOCOMOTE is very instrumental to their success as non-photosynthetic or heterotrophic organisms. This enables them leave one position in search for food and resources
