Which of these would be evidence that cyanobacteria evolved the ability to perform photosynthesis on earth over 2 billion years ago? a) a decrease in glucose in cellular fossils more recent than 2 billion years ago b) an increase in oxygen gas in the atmosphere and oceans starting 2 billion years ago c) an increase in carbon dioxide levels in the atmosphere and soils from 2 billion years ago d) the presence of eukaryotic cellular structures trapped in ice from earlier than 2 billion years ago

Which of the following would be least likely to support the modern concept of biological evolution? ( 2 points) a)different species of organisms with similar bone patterns b)different species of organisms with similar reproductive rates species in c)different domains with similar metabolic pathways species in d)different kingdoms with similar cellular structures.

Seen in some gram-positive bacilli, occurs when only the inner portion of a cell wall is deposited across the dividing cell. this new cross wall puts tension on the outer layer of the old cell wall. eventually, the outer wall breaks at its weakest point with a snapping movement that tears it most of the way around. the daughter cells can then remain hanging together almost side by side being held by a small remnant of the original outer wall. choose from the following statements the ones that correctly discuss reproduction using binary fission in a bacterial cell. select all that apply. view available hint(s) select all that apply. due to the stretching of the cytoplasmic membrane, both cells will contain a complete genome. each daughter cell will contain an equal number of organelles. the daughter cell will be a permanently smaller copy of the mother cell but will contain a complete genome. each daughter cell is an exact copy of the other, both genetically and morphologically

Drag each label to the correct location on the table. each label can be used more than once. decide whether each statement describes saturated fat, unsaturated fat, or both saturated and unsaturated fats.
