Question

question 3
why dont we expect to find life on planets orbiting a high - mass star?
their lifetimes are too short to allow life to evolve & they generally produce more ionizing radiation
theyre too hot to allow for life
planets cannot have stable orbits around high - mass stars

Explanation:

High - mass stars have short lifetimes, which may not provide enough time for life to evolve. Also, they emit more ionizing radiation that can be harmful to life. Planets can have stable orbits around them, and while they are hot, the main issues are time for evolution and radiation.

Answer:

their lifetimes are too short to allow life to evolve & they generally produce more ionizing radiation
