Do ants have blood in their body?
Ants do not have lungs. Oxygen enters through tiny holes all over the body and Carbon Dioxide leaves through the same holes. There are no blood vessels. The heart is a long tube that pumps colorless blood from the head back to the rear and then back up to the head again.

What percentage of your weight is muscle?
Exercise is very important in maintaining a healthy body and the muscle mass % is a useful indicator to control it. The normal muscle mass percentage on the body weight lies between 38% and 54% for men and between 28% and 39% for women depending on age and physical activity level.

How many pairs of ribs does a horse have?
Normally, there are 18 pairs of ribs in the horse, but a nineteenth rib on one side or both is not considered all that rare. Eight pairs of ribs are known as true ribs. They join the segments of the sternum or breastbone. The other 10 are known as floating ribs--merely overlapping and being attached to each other.

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.
