I don't but lately there has been tons of reports about seeing them. I believe there is life on another planet, but I don't believe that they come to hunt us down.

lichens are found to be very sensitive to the levels of contaminants like Sulphur dioxide in air.They can commonly be found growing on barks of trees as a thin greenish white crust.

a)What is the difference between the lichen on trees near busy roads and trees some distance away?

b)On the trees near roads, compare the incidence of lichen on the side facing the road and on the side away from the road

Then why is this question hurting my brain?
When we look at very distant stars, are we looking back in time?
Since we are using light year to measure the distance b/n objects in space, when we look at stars, the light that is hitting us now must have started from the stars long time a go that means the stars appears how they looked like some time ago when the light was emitted from it, right?
Ok in other example, Alpha Century, the closes star to earth is 3 light years away right? Does that mean the light we see from it now, left the star 3 years a go? So if the star was destroyed or gone from it is position, with in this time, we wouldn’t know right?
Am I making things complicated? Or do you get my point?

This is the original question.

You have two pure breeding strains of gold fish. Strain 1 has but one large dorsal fin, while strain 2 has two such fins. You cross them together and all of the progeny have a single dorsal fin. You then mate brothers and sister together and to your utter amazement only 1 in 16 progeny has two dorsal fins. How do you understand this?

I understand the 1st breeding part.
For example GG X gg (GG for 1 dorsal fin and gg for 2 dorsal fin) -> all progency will have Gg genotype and 1 dorsal fin.

However how can they get 2 dorsal fin 1/16 possibility in 2nd breeding?

The following is part of a quilt design. The shaded part is formed by five identical 3 units by 3 units squares. Calculate the length of the diameter of the circle.

The formula for diameter is d = 2√Area/pi. --> area of a circle is a = pi(r)^2. Would the radius be 3, 4.5, or 6?

The picture is here: http://warcount.googlepages.com/square.JPG

It seems like the rotation of the earth should prevent weather from becoming stagnet since the land mass continues to move. Why doesn't the area move out from under a weather system?
