Explanation:
<span>High mass stars are the largest, hottest and brightest while the low mass stars are the smallest, coolest and dimmest. High mass stars use their hydrogen fuel rapidly and have short lives while the low mass stars use hydrogen fuel slowly and have long lives. High mass stars pass through the Red Supergiant stage before dying in supernovae explosions while the low mass stars simply die by burning up their fuel to leave behind the white dwarfs which themselves cool and contract further to black dwarfs.

Answer:
A gene mutation can be described as errors in the nucleotide sequence of a gene due to errors in the DNA replication process or due to any mutagen. On the other hand, a chromosomal mutation can be described as a change in the structure of a DNA or changes in the number of chromosomes.
A gene mutation occurs in a single gene whereas a chromosomal mutation will affect many genes. Hence, gene mutations will be comparatively less lethal than chromosomal mutations.
Example of gene mutation: Sickle cell anemia
Example of chromosomal mutation: Down's Syndrome
Correct answer: B). They can be transformed into any type of body cell.
The stem cell is the biological cell that has the ability to differentiate into other types of cell. These are always found in the multi-cellular organism. These cells are known to be the foundation of every tissue and organ in our body. Embryonic stem cell is pluripotent, it means they can give rise to every type of cell in the body.
Example: Hematopoietic stem cells that give rise to all type of blood cells like red blood cells, white blood cells etc.
Hence, the correct answer would be option B.
