The correct answer is d. 3.5 billion years.
Prokaryotes were the first forms of life on Earth long before simple multicellular life appeared because of their ability to withstand extreme conditions. It is believed that the first living forms were bacteria combined with archaea in the microbial mat (multi-layered sheet).
The intermediate disturbance hypothesis predicts that species diversity will be highest when the frequency and/or intensity of disturbances are intermediate
Explanation:
The diversity of the species is maximised at an intermediate near of anthropogenic as well as natural disturbances. As the competitively inferior disturbances are being tolerated for species disturbance and are termed to be dominant. Co exist of the sensitive species when the disturbance are either frequent or rare, which possess the reduced level of the disturbances. the productivity is predicted as very less due to competitive exclusion. As the disturbances increases productivity becomes less as most of them unable to sustain the regular destructive occurrence. So with the intermediate disturbances productivity is high as the rapid colonizers and dominant competitors are able to coexist.
The name for the tail-like appendage would be flagella
The right answer is Fruiting type.
The sporophore (literally "spore carrier"), also called Fruitbodies, is the reproductive system of the so-called superior mushrooms. It is, in popular language, the organ of the "fructification" of the mushroom mycelium. It contains sporocysts (basid and asci) that differentiate in the hymenium and produce spores in various forms. It is present in the mushroom's cap.
It would be all if u can pick that but if not it depends on what animal the he question is talking about
