Answer:
a) Toxic (gases)
d) Bacterial
Explanation:
Septic tanks are underground structures usually built with concrete or plastic in which wastewater is treated. These tanks are generally used in rural areas and are located near bathrooms and laundry rooms.
If a septic tank is working correctly, it should produce any unpleasing smell. However, when an individual perceives a certain strong bad smell it could be due to the presence of gases (low levels of hydrogen sulfide and high levels of carbon dioxide, and methane) and anaerobic microorganisms such as sulfur bacteria which also produce methane and, therefore, strong smell.
It all depends of what kind of bad smell is the person perceiving. For example, the smell of "rotten egg" is usually due to microbial pollution and gases. Although these gases are not toxic in low levels, they could become highly toxic. It is extremely important to pay attention to smell and give the appropriate mainteinance.
I'm sort of confused, the correct answer should be that 75% would be homozygous dominate and 25% heterozygous dominate and 0% would be anything recessive. I couldn't tell if that was an option because they were all smooshed together. I hope that helped
