What are the only two mammals that lay eggs?
Only two kinds of egg-laying mammals are left on the planet today—the duck-billed platypus and the echidna, or spiny anteater. These odd “monotremes” once dominated Australia, until their pouch-bearing cousins, the marsupials, invaded the land down under 71 million to 54 million years ago and swept them away.

What causes low engine temperature?
When the coolant temp is low it closes and allows the engine to warm to the designed temperature.The are three most likely causes. A defective thermostat that stays open. This allows the coolant to flow thru the radiator and actually overcools the engine. It could also be a defective gauge ot sensor.

What does a lunar eclipse look like from Earth?
Lunar eclipses occur when Earth's shadow blocks the sun's light, which otherwise reflects off the moon. There are three types — total, partial and penumbral — with the most dramatic being a total lunar eclipse, in which Earth's shadow completely covers the moon.

Why does Aspirin help during a heart attack?
Platelets are cells that clump together and help to form blood clots. Aspirin keeps platelets from clumping together, thus helping to prevent or reduce blood clots. During a heart attack. Blood clots form in an already-narrowed artery and block the flow of oxygen-rich blood to the heart muscle.

How long can a penguin go without food?
Since penguins don't leave the nesting areas to feed, some species go through the entire courtship, nesting, and incubation period without food or water. For male king penguins, this period lasts for 55 days. For the male emperor penguin, the fast can last up to 120 days.

What organ produces adrenaline?
Epinephrine and norepinephrine are two separate but related hormones secreted by the medulla of the adrenal glands. They are also produced at the ends of sympathetic nerve fibres, where they serve as chemical mediators for conveying the nerve impulses to effector organs.

How do fish get oxygen out of water?
Gills are feathery organs full of blood vessels. A fish breathes by taking water into its mouth and forcing it out through the gill passages. As water passes over the thin walls of the gills, dissolved oxygen moves into the blood and travels to the fish's cells.

Are clouds made up of liquid or gas?
Clouds, snow, and rain are all made of up of some form of water. A cloud is comprised of tiny water droplets and/or ice crystals, a snowflake is an aggregate of many ice crystals, and rain is just liquid water. Water existing as a gas is called water vapor.

Why do lights flicker in the distance?
When you stand on the ground and look at the stars, about 100% of the Earth's atmosphere is above your head, so the light from stars has to pass through the turbulent air of the troposphere, where it is refracted, giving it a twinkling appearance. From an aircraft, this same thing happens with city lights.

How much horsepower does a person have?
When considering human-powered equipment, a healthy human can produce about 1.2 hp briefly (see orders of magnitude) and sustain about 0.1 hp indefinitely; trained athletes can manage up to about 2.5 hp briefly and 0.3 hp for a period of several hours.
