  1. There are ~350,000 species of angiosperms, and there are less than 40,000 species of all other land plants combined. What evolutionary process resulted in this rapid accumulation of biodiversity from an original, ancestral lineage? In the case of the angiosperms, what specific evolutionary innovations related to angiosperm reproductive biology were likely involved with this explosion in biodiversity? In what way did these novel features allow angiosperms to become so diverse. Present evidence (to the extent we covered it in the course materials) to support your answer. Include in your answer a time frame for when the rapid diversification of the angiosperms occurred.

12: a. A wooded area contains mosses, ferns, gymnosperms and angiosperms. A species of bee is the major pollinating insect in this area. Which type of plant is most likely to be negatively affected if this species of bee becomes extinct? are there any types of plants not going to be affected? Explain. b. What organisms use spores as part of their reproduction cycles? How are these different types of spores alike and how do they differ?

A convex polygon is defined as a polygon where all its internal angles are less than 180 degrees and no edges cross each other. You can assume the vertex with the smallest x-coordinate (assuming origin at bottom left) is the first coordinate and other vertices are numbered in a counter-clockwise direction. Figure 1 shows an example of such a polygon where V[1] is the first polygon. For simplicity, you can also assume all polygon vertices have distinct x and y...

Let P2 be the vector space of all polynomials of degree less than or equal to 2. (i) Show that {x + 1, x2 + x, x − 1} is a basis for P2. (ii) Define a transformation L from P2 into P2 by: L(f) = (xf)'    . In other words, L acts on the polynomial f(x) by first multiplying the function by x, then differentiating. The result is another polynomial in P2. Prove that L is a linear transformation....
