Many plants, such as the potato plant, avoid insect predation by producing highly toxic sap. however, the potato bug, unlike most insects, has adapted to the toxins and can still eat the potato plant. in turn, over a long period of time, potatoes are likely to develop more chemical defenses against the potato bugs.

this type of consistent adaptation between two species is known as
a) co-evolution.
b) commensalism.
c) a realized niche.
d) a fundamental niche.

Find the coordinates of point x that lies along the directed line segment from y(-8, 8) to t(-15, -13) and partitions the segment in the ratio of 5: 2.

Need now max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.

I’ve been trying all day to figure this puzzle out. i need the work for it aswell. it is a factoring polynomials tarsia. the image is below.
