The peaks are there where the centre of the concentric circles lie. (Not circles exactly)
You can count a total 4 of them.
So there are a total of 4 peaks
See the attachment. I have marked them with a cross.

Answer:
the average weight of a frog is 0.8 ounces, so your answer would be 4
To compute for grams of fat in each salad:
We know that, A = C.
And B is 5 grams more, so it is B = 5 + A
And the total fat is 65, so A + B + C = 65 grams.
Computation:
A + (5 + A) + A = 65
3A + 5 = 65
3A = 60
A = 20
A = 20
B = (65 - 40) = 25
C = 20
Answer:
A. Ionic—Magnesium will give 2 electrons to oxygen, and both will become ions.
Explanation:
An ionic bond will form between the ions of both atoms. Ionic bonds forms when there is transfer of electrons between two atoms so as to achieve a noble configuration.
In the given problem, magnesium is a metal and highly electropositive. This implies that it will readily donate its valence electrons. Oxygen on the other hand is highly electronegative, to complete its outer shell configuration, it requires just two more electrons.
The transfer of the two electrons to the oxygen atom sets up an electrostatic force of attraction between the two ions and an ionic bond results.
