A biologist needs at least 4 mature specimens of a certain
plant. The plant needs a year to
reach maturity; once a seed is planted, any plant will survive for
the year with probability
1/1000 (Independently of other plants). The biologist plants 2000
seeds. A year is deemed a
success if 4 or more plants from these seeds reach maturity.
a. Write down the exact expression for the probability that the
biologist will indeed end up
with at least 4 mature plants.
b. Write down the relevant approximate expression for the
probability from (a). Justify
briefly the approximation.
c. The biologist plans to do this year after year. What is the
approximate probability that he
has at least 3 success in 8 years?

A marine biologist claims that the mean length of mature female
pink seaperch is different in fall and winter. A sample of 6 mature
female pink seaperch collected in fall has a mean length of 106
millimeters and a standard deviation of 14 millimeters. A sample of
8 mature female pink seaperch collected in winter has a mean length
of 101 millimeters and a standard deviation of 13 millimeters. At
alphaequals 0.20, can you support the marine biologist's claim?

A biologist measures the lengths of a random sample 45 mature
brown trout in a large lake and finds that the sample a mean weight
of 41 pounds. Assume the population standard deviation is 3.7
pounds. Based on this, construct a 99% confidence interval for the
mean weight of all mature brown trout in the lake. Round your
anwers to two decimal places. < μ

A local biologist needs a program to predict population growth.
The inputs would be:
The initial number of organisms, as an int
The rate of growth (a real number greater than 1), as a
float
The number of hours it takes to achieve this rate, as an
int
A number of hours during which the population grows, as an
int
For example, one might start with a population of 500 organisms,
a growth rate of 2, and a growth period...

A manufacturing company receives orders for engines from two
assembly plants. Plant I needs at least 45 engines, and plant II
needs at least 32 engines. The company can send at most 140engines
to these assembly plants. It costs $30 per engine to ship to plant
I and $40 per engine to ship to plant II. Plant I gives the
manufacturing company $20 in rebates toward its products for each
engine they buy, while plant II gives similar $10 rebates....

Describe at least 4 organelles/structures present in or
associated with plant cells but not in animal cells. Be sure to
include the function and any identifying structural components.
Review basic cell organelles and structures that plants and animals
share. Briefly describe the role of the organelle/structure.
