Which source is the LEAST credible for scientific information?
Margarita [4]

Answer:

D) A Survey of fellow classmates

Explanation:

This is the correct answer because an informal survey involves various answers that may or may not be accurate.  Informal surveys cannot be held as scientific fact and are, therefore, not reliable. A scientific journal is reliable because it most likely includes data from an experiment and/or research of a trusted scientist or group. The results of past experiments are very reliable because these are the results of hard work and thorough planning and research. A scientific discussion with colleagues is not very credible because it involves the sharing of opinionated information, but it is certainly more reliable that the varying answers of school-aged peers.

Why cant or shouldnt you use pet waste in compost
Sever21 [200]
In dog waste, there is a chemical called fecal coliform bacteria. this bacteria is harmful to plants and animals alike, if this compost was used on plants, eating the plants would be bad news. the bacteria can cause cramps, diarrhea, intestinal illnesses, and even serious kidney issues in people. dog poop mostly carries these things

Whipworms

Hookworms

Roundworms

Tapeworms

Parvo

Corona

Giardiasis

Salmonellosis

Cryptosporidiosis

Campylobacteriosis

pet droppings contribute to diseases spread from animals to people called zoonoses, using the pet poop in the compost can make the bacteria linger for years, making further crops infected too.

(really hope this helps!)
