1. what could happen to the reproductive process of mosses during a drought?

a)mitosis in the sporophyte would cease and the reproductive cycle would stop.
b)meiosis in the sporophyte would cease and the reproductive cycle would stop.
c)the flagellated sperm would not be able to swim to the eggs for fertilization.
d) the flagellated sperm and eggs would go dormant until water was available.

2. which of the following is true of conifers?
a)the sporophytes grow directly from the gametophyte b)the gametophytes grow directly from the sporophyte c) the spores release from the male cones d)the spores release from the gametophyte

the answer   is 200

step-by-step explanation:

this is a problem about poisson probabilities.   i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.  

here's how you can see a poisson distribution coming.   when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution.   this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot.   there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything.   the form of the distribution is

  probability of n chips = {[e^(-x)]*(x^n)} / (n! )
