Answer 1

Hint: Cooking oil is synthetic fat which is used in baking, frying, and other types of cooking and is used in food preparation. It is used in flavoring in which heat is not involved like salad dressings and bread dippings which may be known as edible oil.

Complete answer:
Cooking oil should not be thrown down the drain because it can block the drainage pipes. The fats clog the soil pores which reduces its effectiveness in filtering water and therefore blocks the drain pipes. The oil traveling into waterways can cause water's oxygen level to drop which can suffocate the wildlife living in it. Cooking oils are commonly liquid at room temperature but can get solid if the oil contains fat such as coconut oil, palm kernel oil and palm oil. The oil extracted from plant sources are olives, soybean oil, palm oil, canola oil, corn oil, peanut oil, and other vegetable oil whereas the oil extracted from the animal sources are butter and lard. Aromatic foodstuffs like herbs, garlic, or chilies are flavored. The consumption of small amounts of saturated fats is common in diets and it is found that there is a significant correlation between the high consumption of saturated fats and blood LDL concentration which is a risk factor for cardiovascular diseases. Some oils including coconut oil and palm kernel oil are highly saturated fats. The oil having less amount of saturated fats and higher levels of unsaturated fats are generally healthier.

Additional Information: The proper disposal of cooking oil is an important waste management concern as it can congeal the pipes and provoke blockages. The cooking oil should never be dumped in the kitchen sink or the tet bowl. The proper way to dispose of cooking oil is put in a sealed non-recyclable discarding it with the regular garbage. Refrigerating the container of oil makes disposal easier and less messy. The cooking oil can be recycled and used as animal feed which can be directly used as fuel, producing biodiesel and other industrial products. The cooking oil recovered from the restaurants and fruit processing industries which are known as recycled vegetable oil can be used in the recycling industry.
So, the correct answer is 'They block drainage pipes'.

Note: Almond oil is good for eyes and it should be used in salads . peanut oil is good for growing teenagers as they are rich in monounsaturated soybean oil and is good for heart and cholesterol patients. Olive oil helps people over and it is great for salads and to saute veggies.
