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.
Explanation:
There are eight major terrestrial biomes: tropical rainforests, savannas, subtropical deserts, chaparral, temperate grasslands, temperate forests, boreal forests, and Arctic tundra. Biomes are large-scale environments that are distinguished by characteristic temperature ranges and amounts of precipitation. These two variables affect the types of vegetation and animal life that can exist in those areas. Because each biome is defined by climate, the same biome can occur in geographically distinct areas with similar climates .

Explanation:
Protein elastin is used to made elastic fiber, component of connective tissue that found abundant in blood vessels, bones, tendon and skin. The effect should be prominent in those organs.
Aorta is the biggest artery blood vessels and it need more elasticity to withstand the pressure of the ventricle. Less elasticity makes aorta become enlarged. The bone will lose density and become thinner. The tendon in heart valve will be weaken and might cause the heart valve disease. The skin will lose elasticity, so it will be easier to stretch.
