N LIINNN RIGHT ANSWERS ONLY Where is the artic tundra biome found.

A. in tropical and subtropical latitudes
B. almost entirely in the Northern Hemisphere, from 60 to 70 degrees latitude North
C. within tropical and subtropical latitudes
D. in high altitudes

Explanation:

The answer is B because looking at a map, tundra is at 60 and 70 degrees north. Also, the tundra is cold, and the other answers are hot places.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
