Answer:
It must belong to the Kingdom Fungi.
Explanation:
Fungi are the organisms that have long thread-like structures called hypha in their body. Many hyphae together form a mass called mycelium. Fungi are eukaryotes and have a well-defined nucleus in their cells. They also have cell walls that are made up of chitin. Fungi are mostly multicellular. However, yeast is the fungi that have a single cell in their body. Fungi are heterotrophs and derive their nutrition by parasitic or saprophytic mode of nutrition. Therefore, the given description tells that the microbe should be a fungus.
Well, MOST pathogenic bacteria is harmless, but SOME could cause death, like tuberculosis, but just in case you would want to mark the answer as, "True".
I hope I helped! =D
I think it is either y or z. It has been a little bit since I have done this unit though...
Answer:
Five hundred out of every one thousand rats would die
Explanation:
Median lethal dose LD-50 (lethal dose 50%) is used as a measure of poisoning potential of a substance. LD-50 is the dose of substance, given all at once, which causes the death of 50% (one half) of a group of test animals. LD-50 is usually expressed as the amount of chemical administered (e.g., milligrams) per 100 grams or per kilogram of the body weight of the test animal. In this example, the test animals were rats, they were administrated a certain insecticide. Administration methods that are the most common are dermal (applied to the skin) and oral (given by mouth). If the determined LD-50 is 250 milligrams per kilogram of body mass, it means that one half (five hundred) of one thousand rats would die, because we are talking about lethal doses.
