How can plants cause weathering? (1 point)
A. Plants attract animals, and animals can burrow into rocks.
B. Chemical reactions in plants change rocks and break them into smaller pieces.
C. Plants need water, and water can weather rocks.
D. Sprouting seeds and growing roots can cause rocks to break.

C or D either one

Explanation:

Either one.

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.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
