Anything in the environment that can cause a mutation is called as a mutagen.
Environmental mutagens include:
radiations, chemical, infectious agents, extreme heat.
The environment we live in has a real impact on whether we experience genetic mutations. The quality of water we drink and the air we breathe can actually effect the integrity of our DNA. Our bodies are designed to correct any mistakes, but dangers from the environment can increase our chances of ending up with a mutation.

High temps can cause in death because our body is producing sweat and when our body isn't getting enough water, it's dehydrated and can die of heat exhaustion <span />
Answer:
haploid cells!
Explanation:
most body cells go through mitosis, which produces a cell exactly identical to the original cell.
what makes meiosis / sexual reproduction unique, is that they use zygotes. the male zygote (sperm) and female zygote (oocyte) go through mitosis TWICE so that they end up with half the number of things they need. When the oocyte and sperm combine during reproduction, the new cell will have a unique HALF from mom and a unique HALF from dad to make a whole unique cell!
