Scientists have discovered organisms that thrive in hot water that is 90*C (194*F) and do not need sunlight or oxygen to live. Into which kingdom would the scientists classify these organisms? Protista
Archaebacteria
Plantae
Fungi

Archaebacteria

Explanation:

Archaebacteria is one of the three domains in which living organisms are classified into. These set of organisms are characterized by their prokaryotic nature i.e lack of membrane-bound nucleus and their unique ability to withstand extreme environmental conditions e.g heat etc.

Based on the explanation above, the organism described in this question as being discovered by scientists and have the ability to thrive in hot water that is 90*C (194°F) and do not need sunlight or oxygen (anaerobic) to live is likely to belong to the kingdom ARCHAEBACTERIA.

answer; i believe that the correct answer is(d) nondisjunction during meiosis;

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
