Answer:
D) A giraffe's long tail
Explanation:
I'm guessing this is the right choice because:
a. Migration is a survival instinct and doesn't particularly help with energy.
b. A polar bear's thick fur is to protect it from the cold and helps to warm the animal, but it doesn't supply energy.
c. A monkey's long tail is indeed useful for hanging from branch and climbing, yet they have four other limbs that aid in the same process and again, it doesn't neccessarily supply energy.
d. A giraffe's long neck is used to eat from trees since giraffes are herbivores and eat from tall trees, which counts as energy. This is because when the eaten it is later converted into protein to be used energy.

Answer: i think maybe 10.
Explanation:
All of these elements have an electron configuration<span> that ends with </span><span>s1</span><span>. Francium's properties have not been determined experimentally, because so far there has not been enough of it to experiment with </span>Sodium is group 1/IA, the alkali metals, on the periodic table. Therefore, the other elements in this group will have similar properties as sodium. These would include, lithium<span>, potassium, </span>rubidium<span>, and </span>cesium<span>.
Hope this is the answer

I Believe this is the right answer:
Get a periodic table of elements. ...
Find your element on the periodic table. ...
Locate the element's atomic number. ...
Determine the number of electrons. ...
Look for the atomic mass of the element. ...
Subtract the atomic number from the atomic mass.
Hoped this helped!
