Answer:
Asthma and Respiratory Infections can result from harsh toxins.
Explanation:
Asthma and Respiratory Infections are caused due to atmospheric conditions and chemicals, and things like pollution can contribute to it.
Sickle-cell Anemia and Color Blindness are inherited diseases, and are not caused by toxins in the environment.
Diabetes is caused by an excess amount of sugar in the blood and is not related to harsh toxins, just sugar.

Answer: b. The elderly have a higher risk from toxic pesticides because they are less able to eliminate environmental toxins.
Explanation:
The older adults are expected to have health problems after a pesticide exposure. This is because of the fact that their metabolism is slow and the liver and kidneys are not able to remove the pesticides from the body. The liver and kidney may get injured during the exposure of the high doses of pesticides.
The longer a pesticide stay in the body of an old person this may result in more severe injury. As the body is slow in metabolism that is the conversion of the chemicals in the pesticides into less toxic metabolites. Thus the elderly people will not be able to eliminate the toxin from the body. The toxin will damage the vital organs and can lead to death.
Answer:
The answer to the question: Electrical impulses or action potentials (AP) cannot propagate across a synaptic cleft. Instead, neurotransmitters are used to communicate at the synapse, and re-restablish the AP in the post-synaptic cell, would be, true.
Explanation:
Essentially, although the CNS, PNS and ANS (Central Nervous System, Peripheral Nervous System and Autonomic Nervous System) are electrical systems, that use the electricity generated through action potentials, that in turn, are created by the exchange of electrically charged ions from within and without the neuronal cells, these electrical impulses do not pass the pre-synaptic, and post-synaptic cleft. Instead, once an AP has reached the terminal end of the pre-synaptic neuron, neurotransmitters are released by this one, into the cleft, which are then taken up by the receptors present in the post-synaptic neuron. Depending on the type of transmitter released, there will be an inhibitory or excitatory effect. Then, with the transmitter attached, the post-synaptic neuron will depolarize and a new AP will be generated in the post-synaptic neuron, which will carry on. Messages, thus are transmitted that way between neurons, and also, between the nervous system and the organs they influence.
