Answer:
D) None of the above
Explanation:
Arthropods are characterized by the possession of an exoskeleton and a segmented body. This group includes insects, arachnids, myriapods (centipedes and millipeds), and crustaceans.
The Devonian period, belonging to the Paleozoic Era, occurred from around 415 million to 350 million years ago. During this era, arthropods such as centipedes, millipedes, and flightless insects were predominant and diversified throughout this period.
Therefore, as all of these arthropods were present in the Devonian period, the correct answer is <u>d) None of the above</u>.
Answer: a) relies on the uptake of an external signal molecule from the cell
Explanation: Signal transduction is known as the transmitting of any signal of a molecule from exterior of cell to interior of cell.This technique is termed as critical is taken care of successful transmission of signal effectively and positive result and reception is done by the cell surface receptors.It is also known as cell signalling. Thus,option(a) is the correct option of all.

<span>Meiosis is the process of cell division that reduces the chromosome number by half. During the process two phases (two nuclear divisions) occur: Meiosis I and Meiosis II. Meiosis I is the phase of reduction and Meiosis II is the division. So, if a cell under a microscope shows two daughter cells and they aye haploid than this is the stage Meiosis II, in which the cell is divided into two daughter cells.</span><span />
