The answer is C
Completing multiple trials during an experiment
The rest of the options are possibilities of how you can "mess up" and experiment, but if you run multiple trials doing everything right, for example, making sure all variables are controlled, using the right equipment, and making sure you cover all possible variables. If you make sure you do multiple trials and you do them right, you get successful results.
So the answer is C
I hope this was helpful :)
Goodluck!!
Answer:
Are you referring to symbiotic relationships between organism? If so, the answer would be parasitism.
One organism, a parasite, takes advantage of another organism at the expense of the host organism.
Ex. A tick bites a dog for blood to use as food. The dog gets an uncomfortable bug bite and the dog might catch a tick borne disease.
A is correct. 10% of 100 is 10, so therefore, 10 members of the species have that particular phonotype. Hope this helps!
Well, I may not name ALL of the minerals, but I can give you the names of some minerals I've known about:
1. Quartz
2. Magnetite
3. Mica
4. Diamond
But just to let you know, there are many minerals out here on Earth. All you have to do is either remember some minerals you know of, or just do some research.
