Answer:
C) layering, directional pressure
Explanation:
The foliated metamorphic rocks are those rocks subjected to heat and pressure during metamorphism, characterized by presenting a parallel alignment of minerals, which gives the rock an appearance of layers or bands.
D. She should look for ovals full of green dots called chloroplasts.
A group of cells that performs a similar function is known as tissue.
The best evidence of such phenomena could be a population's genetic variation decrease.
When a population bottleneck occur it means that for some reason (i.e. environmental events) the size of a population is largely reduced. This leads to reduction of the genetic variation in that new smaller population. When a bottleneck occur, the founder effect is normally seen, which is that one population is established by a small group of a previously larger population leading once again the genetic variation, now though with a bigger population, to be very reduced.
