Bacteria: are single-celled microscopic organisms that are characterized by the presence of incipient nucleus and few membrane-less cell organelles.
Fungi: are eukaryotes that are characterized by the presence of chitin in the cell wall.
Cell Type: All bacteria are prokaryotes. All fungi are eukaryotes.
Answer:
<u>Pathway A and B</u> are <u>anaerobic</u> ways of extracting energy (ATP) from glucose. These pathways are advantageous when little or no oxygen present. The net energy in both pathways is 2ATP. Both pathywas take place in the cytosol of the cell and are categorized as fermentation.
<u>Pathway C is aerobic</u> in which oxygen is used to yield energy (ATP). This pathway is advantageous when energy needs are high because it produces 36 molecules of ATP. Therefore, net energy in this pathway is higher than the anaerobic pathways. This pathyway takes place within the mitochondria and is recognized as cellular respiration.
A schematic illustration can be seen in the image attached.
PS: <u>Glycolysis</u> is common to fermentation and aerobic respiration.

Explanation:
Homo erectus existed about 200 million yeas ago as one of the early man to occupy the old world. Homo erectus are said to be the direct ancestors of other homos. The brain size of homo is population dependent and it ranges from 546–1, 251 cc (33.3–76.3 cu in). The maximum size of the brain was achieved early in their life to
this is similar to childhood in modern human.
Body size ranged widely from 146–185 cm which is about 4 feet 9 inches –6 feet 1 inch in height and 40–68 kg in weight.
Homo erectus have a flat skull that is low. The face is also flat compare to modern humans with brow ridge.
Fossils can support this hypothesis due to the fact that some fossils of the same dinosaur species were found on continents that are now very far apart. For example fossils of the plant Glossopteris have been found in South America, Africa, India, Antarctica, and Australia. The only theory that makes sense for the finding of these fossils is that the continents were once all connected.
