Derived characteristics refers to those traits that have changed from ancestral form or function. The derived character, which cause K. monera to be divided into K. archeabacteria and K. eubacteria is that genetically and biochemically the two are different. The archeabacterial possess unusual lipid, which is not find in eubacteria or any other organism. And this give it the capacity to live in extreme environments.

Sorry the font was too big but yea...
Mitosis can occur in both haploid and diploid cells because it is equational division where the number of chromosomes remain the same after division. But meiosis cannot happen in haploid cells because it is reductional division and haploid cells do not have any extra copy of chromosomes to be halved.
Mitosis is the cell division where the number of chromosomes do not change after cell division. It usually happens in the somatic cells of the body. Cancer cells also undergo mitosis
Meiosis is the cell division where the number of chromosomes are halved after cell division. The process of meiosis occurs in two phases: meiosis I and meiosis II. The germ cells of the body undergo meiosis.

Answer:
A diving regulator is a pressure regulator that reduces the pressure of gas in the tank and deliver it to the diver so that he/she can breathe easily. It must pass the controlled laboratory testing and must have a second adjustment knob to ensure ease of breathing. Modern regulators are precision made and designed to work under demanding conditions. 1st stage and 2nd stage, diaphragm and piston, exhaust valve and purge button are types of diving regulators.
It will be transported into the cell through the process of endocytosis, which is a form of active transport. Active transport requires energy in the form of ATP. Hope this helps! :)
