You have to find the similarities and differences of intrusive and extrusive igneous rocks for the first question. The second one requires you to find out coarse-grained rocks are formed, the third is asking how igneous rocks are classified according to its structure, like the construction of the rock(what it is made up of). The fourth is asking you how fine grained-igneous rocks are made basically, the fifth is asking you how do igneous rocks with that glossy fine stain, how are they made.
If the concentration inside the cells is the same as outside (water) than it should move at the same rate. Only if the cell's concentration in the inside is more than it is on the outside is when water would move faster going in.
Hope this helps(;

Answer:
Proportion of the F2 male with red eyes and forked bristle will be 1/4
Explanation:
forked bristles are caused by an allele (Xf) that is X linked and recessive to an allele for normal bristles (X+).
Brown eyes are caused by an allele (b) that is autosomal and recessive to an allele for red eyes (b+)
A female fly that is homozygous for normal bristles and red eyes mates with a male fly that has forked bristles and brown eyes
X+X+b+b+ x Xfbb
the F1 gives 1/2X+Xf 1/2b+b
1/2X+Y 1/2b+b
intercross of F1
Proportion of the F2 male with red eyes and forked bristle will be
forked bristle= Xfy = 1/2 and for red eyes 2/4= 1/2 = 1/2x1/2 =1/4
