Answer:
Option b. is correct
Explanation:
If hydronium ion concentration 
is given then pH is given by ![-log[H_3O^+]](https://tex.z-dn.net/?f=-log%5BH_3O%5E%2B%5D)
The hydronium ion refers to the hydrogen ion in aqueous solution.
A Tomato has A Proton Concentration Of 0.00006 M
Here, 0.00006 is equal to 6 × 
So,
pH is given by - log [6 × ]
Option b. is correct
Answer:
The correct answer is 4.ecosystem.
Explanation:
An ecosystem is a system, that is, a set of elements that interact with each other, in which such elements are: physical environment, living beings and their interactions (predator-prey, parasite-host, competition, symbiosis, pollination, distribution of seeds , etc.) The interrelation between living beings (competition, parasitism, etc.) occurs through cycles of matter and energy flows on which the functioning of the entire ecosystem depends.
Answer:
B. Black Squirrels have a survival advantage over gray squirrels
Explanation:
Using the information provided, it can be inferred that there is a difference between how many Gray squirrels and how many Black squirrels are being naturally selected.
This means:
Black squirrels have an advantage that reduces the amount of squirrels being selected from their environment.
Hope this helps!
