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>

Answer.
Actually all of these are involved.
Explanation:
Transcription is the process where genetic material or DNA is copied into RNA by the enzyme RNA polymerase. The transcription unit is made up of a promoter, a protein-coding sequence an attenuation sequence, a termination sequence. The rotein coding sequence contain the structural genes which Consist of two strands which is known as template strand and coding strand. Attenuator sequence can be as a result of stop signal which can also lead to transcription.
Answer:
answer is point b is taxonomic diversity
There are a lot of human activities that gives negative effects on the earth's ecosystem but I will mention only four: Burning of things such as garbages or plants and trees, dumping of garbages anywhere, chemical substance that are being made and produced, cutting down of trees for replacement of buildings and homes. The human activities increase the occurrence of species extinction by doing this, it eliminates and destroy the homes of the species that are supposed to be living on their natural habitat. But instead of them, living peacefully, by doing these activities, their home will be destroyed that can kill them-- which can lead to extinction.
Answer:
I started out as glucose, got converted to pyruvate, after which I got oxidised by Oxygen to become CO2
Explanation:
My name is CO2, and I started out as glucose from pure honey. I got eaten by a little child when I was two weeks old, and I had to go through the dreadful process of aerobic respiration in the child's body.
My glucose molecules were broken down into pyruvate, and I stayed that way for a while, as I made my way to the mitochondria of the child's cells. Once I got to the mitochondria, I met my old friend oxygen, who reacted with me to turn me into the molecule I am today - C02.
If you want to know how I escaped the child's body, that's easy - I simply snuck out his nose while he was breathing one cold dark night.
