The thermoacidophile Sulfolobus acidocaldarius lacks peptidoglycan, but still possesses a cell wall. Which of the following stat

Eddi Din [679]

Answer:

c and d

Explanation:

A species of an organism with cell wall that lacks peptidoglycan is definitely not a bacterium because bacterial cell walls usually have peptidoglycan.

One particular group of organisms whose cells have cell walls but lack peptidoglycan is Archaea.

Archaea represents a group of prokaryotes that are able to survive in extreme conditions such as high temperature, pressure and salinity. As such, they could inhabit hydrothermal springs as well as alkaline hot springs.

Hence, thermoacidophile Sulfolobus acidocaldarius is likely to be an Archaea and could inhabit both hydrothermal springs and alkaline hot springs.

The correct option is option c and d.

How would earth be different without photosynthesis?

Sunny_sXe [5.5K]

Without any photosynthesis, there would be no plants which would lead to the many of the civilians of Earth starving to death. In the likely scenario where photosynthesis does not occur the world would most likely go into an apocalyptic way with the human race as well as many other mammals dying. The organisms that would survive might be used as a food source but the population would drastically decrease

Which of the following types of mutation would convert a proto-oncogene into an oncogene?

Diano4ka-milaya [45]

I think the correct answer from the choices listed above is option A. The type of mutation that would convert a proto-oncogene into an oncogene would be a deletion of most of the proto-oncogene coding sequence. Hope this answers the question. Have a nice day.
