Biology! Any help is appreciated! Thanks!

Most non-vascular plants are small because they can only transport water short distances.

Explanation:

Vascular systems in plants enable the water to circulate higher in the plant. Without it, the plant has no way of getting the water to it's higher parts.

b. read the phase at the intersection of any given temperature and pressure.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
