Answer:
Transition metals, alkali metals, alkaline earth metals Transition metals - Middle of the periodic chart, only average reactivity. alkali metals - As mentioned above, very reactive. Bad choice, going from lower reactivity to higher reactivity.
Hope this answer is right!
Answer:
Glucose will move from the solution B to the solution A
Explanation:
Given that:
Solution A contains 1% glucose, and,
Solution B contains 5% glucose
Diffusion is the net movement of the substance from the region of the higher concentration to the region of the lower concentration.
Thus, solution B contains more concentration of glucose as compared to solution A. <u>By the process of diffusion, the particle moves from higher concentration to lower concentration and thus, glucose will move from solution B to solution A.</u>
I am very sure that the answer is C. Hope it’s right :)
Couple of things:
1: only one type of bacteria was discovered metabolising sulphur, this does not necessarily mean that other bacteria, or indeed another organism can also metabolise sulphur. For his theory to be correct, many more and different types of organisms, metabolising sulphur needs to be discovered.
Secondly the use of the word diverse infers that more than just bacteria can metabolise sulphur. Bacteria are unicellular (single-celled) organisms, we therefore cannot say that multicellular organism can also do this, it could be specific to that one type of bacteria.
