In Africa, there is grooved bedrock and there are glacial deposits called tillites that are more than 240 million years old. These are found along the equator, in areas with a very warm
climate. What could you infer from these rocks about the position of this part of Africa in the
past?

explanation:

allergens: overstimulate the nerve system

neurotics: attack nerve cells

mutagens: damage or otherwise alter dna sequence

generators: cause defects during growth and development  

carcinogens: cause unchecked cell growth

i hope you get the idea according to me these are the effects that happened.
