____ are substances that cause birth defects.
teratogens
vectors
carcinogens
neurotoxins
allergens

question 10
____ are toxicants that interrupt essential biochemical processes in organisms by blocking one or more steps in important biochemical reactions.
pathway inhibitors
carcinogens
neurotoxins
insecticides
mutagens

question 11
bisphenol a is ____.
a banned insecticide
produced when fossil fuels are burned
an estrogen mimic used in plastic manufacturing
released from aerosol spray cans
a currently used herbicide

question 12

Explanation:

• Question 9: Teratogens are substances that can cause birth defects. Vectors are agents that transmit diseases. Carcinogens cause cancer. Neurotoxins affect the nervous system. Allergens cause allergic reactions.
• Question 10: Pathway inhibitors interrupt essential biochemical processes by blocking steps in reactions. Carcinogens cause cancer. Neurotoxins affect the nervous system. Insecticides kill insects. Mutagens cause mutations.
• Question 11: Bisphenol A is an estrogen mimic used in plastic manufacturing. It is not a banned insecticide. It is not produced when fossil fuels are burned (that's more like pollutants like sulfur dioxide etc.). It is not released from aerosol spray cans (aerosol propellants were things like CFCs in the past). It is not a currently used herbicide.

Answer:

• Question 9: Teratogens
• Question 10: Pathway inhibitors
• Question 11: an estrogen mimic used in plastic manufacturing
