Answer:
1.The group of organisms with cells which contain of nucleus and other membrane bound organelles are called Eukaryotes. These organisms have their DNA arranged in the chromosomes, bounded by histones proteins. They have diversity of forms, thus they can be colonial, unicellular or multicellular in forms. Their cells reproduced by mitosis and meiosis for gamete formation.
Reproduction can be sexual and asexual. Their ribosomes are found in the cytosol, and they are larger than that in prokaryotes, but ribosomes in chloroplast and mitochondria are similar as that in the Prokaryotes (70s). Plants and complex animal cells are examples.
Group of unicellular organisms which lack membrane bound nucleus, and other organelles, are called Prokaryotes. Their two domains are the bacteria and archaea. They reproduce asexually only, by fusion of gametes. Due to lack of membrane bound organelles, their water soluble components and cellular inclusions (metabolites and DNA) are found in the cytoplasm bounded by the cell membrane.
<u>When viewed under microscope. Prokaryotes are similar to Eukaryotes as follows. </u>

Well, it depends on what the parents would want. I personally would still have the child.
Answer:
Advances in DNA technology have allowed for treatments such as gene therapy in the medical field. Nowadays, there are tools like the CRIPSR-Cas9 - harnessed from bacteria's immune system- that can nip a ‘bad’ region of DNA, which is responsible for disease, and replace it with a proper functioning bit. This is how genetic disorders are going to be addressed in the near future in mainstream medical facilities.
Recombinant DNA technology is being used to create clones of transgenic organisms that produce products of significance in the medical fields. An example is incorporating the insulin gene in bacteria genome. These clones of modified bacteria colonies secrete insulin protein that is purified and injected in diabetic persons to lower their sugar level to normal.
The image shows a red blood cell in different solution. The first image shows an RBC in a hypotonic solutions. The RBC swell and lyse because of the osmotic movement or referred to as hemolysis. The second image shows a normal RBC in an isotonic solution. There is no net change of water to the RBC. The third image shows a shriveled RBC in a hypertonic solution. The water leak out of the RBC briskly than it enters the cell. It is also called as crenated cell.
Answer - Option C - hypotonic solution
