The hairlike cells in the cochlea are <u>Mechanoreceptors
</u>
Answer: Option A

Explanation:
Palaeontologists study the fossil and once they found that the fossil of an organism in layer 2 and 3. The fossil present in layer 3 is very similar to the fossil present in layer 2.
From this, it could be concluded that the layer 3 possible might be evolved from the fossil present in layer 2. The fossil of layer 3 might be a close relative of the extinct fossil of layer 2 as they could have shared a common ancestor.
Many possibilities could be explained but these two are more valid.
The difference between is metaphase in mitosis has ‘pairs of chromosomes’, while metaphase in meiosis have ‘spindle fibers’. They are the same because metaphase 2 is found in meiosis 2. The metaphase 2 in mitosis, chromosomes are arranged on the metaphase plate and are attached to the completed spindle.
