Answer: The correct option is A
Archae bacteria are extremophiles which thrive in extremely environment.
Explanation:
Extremophiles are organisms that inhabit extreme environments. They thrive in hot niches, ice, and salt solutions. Some of them grow in toxic waste, organic solvents and heavy metals. Extremophiles include members of all domains of life which are bacteria, archea,and eukaryotes. Out of these three members of extremophiles, archea are the main group of microorganisms to thrive in extreme environments. This is because the archea are skilled in adapting to different extreme conditions than bacteria and eukaryotes.
Archea are hyper thermophilic microorganisms.

Answer:
Sister chromatids.
Explanation:
Sister chromatids are the two identical halves of a chromosome that are held together at centromere with help of cohesin. DNA replication in the S phase of the cell cycle doubles the amount of DNA. The copies of the DNA formed during DNA replication are accommodated in sister chromatids. Hence, two sister chromatids of a chromosome carry the identical DNA helices and associated proteins.
1. Pathogens enter the body through a cut in the skin
2. Cells recognize the foreign invaders
3. Histamine is released
4. White blood cells travel to the invaded area
Hope it helps.
The answer is aneuploidy.
This means having an abnormal number of chromosomes
in a cell. MAD protein ensures that the spindle fibers
during metaphase of mitosis, attach properly.
The MAD protein inhibits progression to anaphase if this
process of spindle attachment is defective.
