Answer true or false to the following statements:

a) blood in the pulmonary arteries of a lizard would be partly oxygenated whereas blood from the pulmonary arteries of mammals is deoxygenated.

b) the pulmonary vein carries oxygenated blood in mammals but only partly oxygenated blood in lizards.

c) blood in the aorta of a lizard has a higher oxygen concentration than blood in the pulmonary vein.

d) the difference between the oxygen concentration in arterial blood and venous blood would be greater in mammals than in lizards.

I really need help in this, so any ideas? :-)

In STATISTICAL MECHANICS &THERMODYNAMICS u can observe these vars .Basically,i know that :
INTENSIVE VARS: These are independent of matter present in the system.
EXTENSIVE VARS:These are directly proportional to the matter enclosed by the system.
The extensive vars are the fundamental quantities.The first derivatives of the ex.vars are teh intensive vars.
FOR EXAMPLE:
EX.VAR: total volume,mole number,etc.
IN.VARS:pressure,temperature,etc.

We always have cold fronts coming into Britain from the Atlantic, bringing wind and rain. Would huge blowers, or something similar, be able to force them back out?

Last night I was outside enjoying the stars and a little lower in the sky I saw what I thought was a twinkling star. I looked a little longer and saw colors. I got my binoculars and this "star" was twinkling red, green and white lights. It was not a plane because in was in the same spot for over 20 minutes until the trees blocked my view. Any ideas? If it makes any difference, I believe it was in the North western sky in northern Westchester county in NY.
