If copies were not made before cell division, than I believe both cells would only have half the proper amount of Chromosomes, as I don't think it's possible for one to have all chromosomes, and another cell to not have any.
D because they are complete systems
Answer:
glycosidic bonds between monosaccharides that combine to form polysaccharides
Explanation:
The building blocks of carbohydrates are individual monosaccharides (i.e., sugar molecules), such as glucose, fructose, glucuronic acid, galactosamine, glucosamine, etc. These individual monomers of carbohydrates bond to form polysaccharides such as cellulose and starches. Monosaccharides form glycosidic bonds with an alcoholic OH group of a second monosaccharide to form a disaccharide (for example, lactose), and then these larger molecules bond together to form either linear or branched polysaccharides. Starch, for example, is a polysaccharide composed of monomers of glucose molecules.
Answer:
D. It is able to form colonies and produce oxygen.
Explanation:
Cyanobacteria are the photoautotrophs and carry out oxygenic photosynthesis. These prokaryotic organisms use water molecules as an electron donor during light-dependent reactions of photosynthesis and release oxygen gas as a by-product.
Cyanobacteria are considered to be the first organisms on the earth to perform oxygenic photosynthesis and are supposed to be responsible for the present-day oxidative atmosphere of the earth. Most of the cyanobacteria are colonial forms and are present as colonies of a large number of cells. However, unicellular solitary forms are also present.
The process that makes proteins is called protein synthesis, this process uses transcriptions to change DNA stands into RNA, and they are set into codons and paired with anti-codons. After this, they are put into sets of three, and they are set with amino acids
