2. Why do scientists often use thermoacidophile group of archaebacteria for research?
Archaebacteria have some unique characteristics.
Although members of kingdom Archaebacteria share many characteristics with members of kingdom Eubacteria, some of their characteristics are unique.
One such characteristic is the ability of archaea to live in extreme conditions.
What is Thermoacidophile archaebacteria?Thermoacidophile archaebacteria are a type of archaea that thrive in extremely hot and strong acidic (with low PH) environments. Thermoacidophile archaebacteria can be found in harsh environments such as in geothermal area, in the deep ocean vents and hot springs. Most of the
Thermoacidophile archaebacteria are chemotrophs (converts chemicals to food). They use sulfur as their energy source. They absorb the sulfur gas that is being released in their environment and reduce it to hydrogen sulphide, fixing it into an energy source.
Thus, this could be the answer.

B. 70% of the human body.
C. Controls negative feedback mechanisms.
D. Contains and moves ions in and out of cells.
The following that does not relate to water is it contains and moves ions in and out of cells. The correct option is D.
What is water?Water is a chemical compound made up of hydrogen and oxygen. It is a necessary part of life. As our body is made up of 90% of water, and without water, organisms would not survive.
The transport of ions and molecules in and out of the cell is done by the cytoplasm filling in the cell.
Thus, the correct option is D. Contains and moves ions in and out of cells.

Traditionally, the classification of fungi has been based on the nature of sexual stages of the life cycle. For Penicillium, however, no sexual stages of the life cycle have been observed. Without evidence from sexual stages, speculate about other possible sources of evidence that scientists may use in classification.
Answer:
Without the evaluation of sexual stages, fungi can be classified according to the type of colony they present, the speed of growth, the formation of pigments and the type of coloration.
Explanation:
Although the observation of sexual stages is extremely efficient for the classification of fungi in the laboratory. This type of analysis is not always possible to be carried out. In that case, scientists need to find other methods that allow for the classification of fungi. These methods are carried out with the help of a microscope, where scientists observe the morphology of the fungi and are able to classify them according to the type of colony they present, the speed of growth, the formation of pigments and the type of coloration.
