<span>The right anwer is (b). Indeed, some scientists consider viruses as non-living because viruses do not undergo mitosis, which is the usual way living cells reproduce themselves. On the contrary, viruses inoculate their genetic material in a host cell in such a way to force the cell to make a copy of the virus DNA, thus making more viruses, that then kill the host cell and disseminate themselves. In practice the viruses exploits the replication tools of the living cells to replicate themselves, since they lack the machinery and also they lack something resembling cell metabolism, i.e., they do not "eat" or "grow".</span>
<span>There are many types of algae. Some of which are brown algae or the Phaeophyta/Phaeophytes,the green algae which is also known as the Chlorophytes, and the Chrysophytes or the golden algae. Among these algae, only the Chrysophytes shows distinct alternation of generations or metagenesis.</span>
Answer:
The three main domains into which the organisms are classified are archaea, bacteria and eukarya.
Archaea : The archaea is more closely related to eukaryotes. Although they have bacteria like metabolism and have 70'S chromosomes but shows presence of introns and shows similar molecular mechanism like replication, transcription and translation similar to eukaryotes. These are found in the extreme conditions as well.
Bacteria: The bacteria have circular DNA with 70'S ribosomes. The cell membrane has ester linkage and no nucleosome formation occur in bacteria. The transcription and translation are coupled together with no further modification.
Eukarya: The eukaryotes have linear DNA with 80'S ribosomes. The cell membrane has ether linkage and proper nucleosome fprmation occurs in eukarya. The transcription and translation occurs separately in the distinct compartments and further modification occurs.
The proton is connected to the atomic number of elements. Protons and neutrons make up the nucleus of the atom while electrons are found around the nucleus
First atom
proton: 3 Neutrons: 3 Electrons: 3 atomic number: 3 mass: 6 Isotope name: Lithium-6
Second atom
Proton: 3 Neutrons: 4 Electrons: 3 atomic number: 3 mass: 7 Isotope name: Lithium-7
