Answer:
thick, insulating fur
Explanation:
If an animal lives in a freezing climate, it makes sense logically that the animal would adapt and develop a layer of thick fur to keep its body insulated and maintain homeostasis.

Answer:
True
Explanation:
The given statement is true. The elements on the upper right side of periodic table accept the electrons because of higher electronegativity values and form anions.
For example:
Consider the halogens. All halogens accept the one electron per atom to complete the octet and form anion. when they combine with metals metals loses their electrons to halogens atoms and form cations while halogens accept the electrons and form anion.
Consider the sodium chloride salt. The sodium metal loses its one valance electron which is accepted by chlorine.
Na⁺Cl⁻
Magnesium bromide:
To complete the octet bromine required one electron. By gaining the one electron it showed -1 oxidation state.
When bromine combine with magnesium both formed MgBr₂.
The one atom of Mg have +2 oxidation state while bromine have -1 that's why to make the overall compound neutral two bromine atoms combine with one atom of magnesium.
Answer:
It is true that a characteristic of rock is that each of the component minerals retains its properties in the mixture.
Explanation:
Rocks are composed of two or more minerals. A rock is any naturally occurring solid mass or aggregate of minerals or mineraloid matter.
These minerals have been
1) cemented together
2) squeezed and heated together, or
3) melted and cooled together.
One of the most common rock is granite. The four minerals that make up granite are feldspar, quartz, mica, and hornblende. Each of these minerals retain their property in a mixture form in a rock.
Answer:
electrons can bond atoms together
Explanation:
when two atoms share electrons,they are locked together by that sharing.These are called covalent bonds...but when an atom gives one of its electrons to another atom ,they are held together by electric forces.HOPE THAT HELPED☺
