The beetles that died were unable to avoid or detoxify the chemical and were thus killed by nerve poison insecticides.
- Chemicals called insecticides are used to kill insects or stop them from acting in an unwanted or destructive way. Their structure and mechanism of operation are used to categorize them.
- Most insecticides function by interfering with the insect's nervous system. The herbicide prevents neurotransmitters in synapses from transmitting information.
- Acetylcholine is the name of the substance that the body produces and uses to transmit information through synapses. Muscles can relax because of an enzyme called cholinesterase that binds to acetylcholine.
- Through the synapses, acetylcholine communicates with the muscles. The cholinesterase is impacted when a pesticide is administered at a deadly dose for a specific body, preventing it from binding with the acetylcholine.
- The muscles become overstimulated as a result, which will cause paralysis and death.

I think the correct answer would be the last option. People with one sickle cell allele are not likely to get malaria. This would be an example of genetic drift. It is one of the mechanism of evolution which involves the change in the frequency of an allele in a certain population due to the random sampling of the organisms. It is when a certain trait is being spread by chance rather by natural selection. Sickle cell is classified as an autosomal recessive disease that is caused by hemoglobin. It is a disease that is inherited depending on how the alleles are received. So, it can be inherited by chance.
I think it is the last choice that you put down. hopefully that helps.
The social sciences are scientific in the sense that we seek true knowledge of man and his society. Same as for science
