Question 1
particles of liquids and gases move much more freely than do particles of solids.
options:
true
false

The following statement is true. Gases and liquids are the two states of matter that move around more freely than the solid particles.

This is due to the fact that the molecules of water and gas are lighter and less densely packed. They can slide past each other and move around easily. These particles can take whatever shape they are kept on.

Out of gases and liquids, the molecules of gas are less densely packed and flow freely. They are also easy to compress than a solid or liquid. Meanwhile, solid matters have its own shape, its molecules are tightly locked with one another which is much harder to compress.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

the correct answer is sex-linked recessive.
