The correct answer is: a. n+1, n+1, n-1, n-1
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during mitosis or meiosis. There are three forms of nondisjunction:
1. failure of a pair of homologous chromosomes to separate in meiosis I ,
2. failure of sister chromatids to separate during meiosis II, and
3. failure of sister chromatids to separate during mitosis.
As a consequence of nondisjunction abnormal chromosome numbers appears. If nondisjunction occurs during the meiosis I (anaphase I), this means that at least one pair of homologous chromosomes did not separate. The consequence is two cells that have an extra copy of one chromosome and two cells that lack that chromosome.
No they do not have the same process but they are very close and work in function with each other
The Stroma is the colorless fluid surrounding the grana (or Granum) and enzymes in the process of photosynthesis is embeded in the stroma and also the thylakoid membranes
Thylakoids are the site of the light-dependent reactions of photosynthesis. Thylakoids<span> consist of a </span>thylakoid <span>membrane surrounding a </span>thylakoid<span> lumen. They normally stack up in stacks called Granum and the Stroma surrounds</span>

Answer:
1. Bacteria cannot live above 100 degrees Celsius; archaea can thrive in extreme temperatures. Archaea are actually extremophiles. They can survive in extreme physical and geochemical conditions.
2. Bacterial cell walls have peptidoglycan (mesh-like structure also known as murein); archaeal cell walls do not have peptidoglycan.
