I have checked a few websites. They all said praying mantis' are masters of camouflage and make use of protective coloration to blend in with the foliage, both to avoid predators themselves, and to better snare their victims. However, I haven't found anywhere that stated how long it takes the insect to change coloration if it moves from say a brownish area to a green leafy area.

When I look at city lights from a distance, no matter how still and unobstructed my line of sight is the distant lights always appear to be pulsing or flickering. Why is this? Is there a scientific explaination?

In the scheme of things is it possible that homosexuality has been put into place by nature to curb population explosions? Have any studies been made within biology that may suggest I am right? If I am right is homosexuality in direct proportion to the increase of population?

Is it propellers? Paddles? Mississippi-Steamer type wheels? Some bionic design, emulating penguin's feet? I'm trying to find the implement which will translate the highest percentage of the horsepower I produce with whatever means (muscle power, electric motor, diesel, who knows) into propulsion in the water.

It's for a boat project. I want to build my own boat, and I want to build the most efficient, possible drivetrain for it.

Thanks!
