biology help!?

Why do you suppose there are usually equivalent numbers of males and females in most species?

Why would natural selection favor an even number of males and females? Why is this evidence that natural selection acts on individuals rather than populations?

Can anyone tell me if a Scarlet Kingsnake can be found in NY State?

I am deathly afraid of snakes and I'm trying to work through my fear. It stems from a childhood incident when I saw what I always thought was a water moccasin. Looking at pictures, however, I noticed that the coral snake looks like what I saw that day. Being as they aren't normally found in NY, I thought I'd look into any look alikes. I found the Scarlet Kingsnake, but can't find anywhere if they can be found in NY. If you can help I'd really appreciate it. I think if I find out the snake I saw wasn't poisonous, it'll help me get over my fear. Please, no rude or disrespectful answers.

Im in My 50's And For Most OF My Life Remember The Weather Being Weird Every So Often In MY Life <Why Then?

I have remembered weird weather every since I was a child.Freak snow storm here,tornado there hot when its suppose to be cold ,cold when its suppose to be hot..Hurricanes bunches in one year then five years without ..Freak rain and hail storms and everyting and anything.Most people I have talked to remember the same things..Not really that big of a deal.. Even in history there are countless freak strorms and weather systems..So why does everybody now say GREENHOUSE gases and crap?That is the funniest thing that I have ever heard.When I was growing up nobody even thought about greenhouse gases..they said its just mother earth changing.and if you read centuries ago before pollutants or the massive amounts we have dumped in the air they had the same weather.Whats with everybody..and the Freaks show"IT COULD HAPPEN TOMMOROW" Weirdos man.. These people don't realize it did happen and has happened and will continue to happen.Dont you remember things like this when u were young?Its normal!
