Why do you keep the lies in the textbooks?

ex. Miller Experiment, Darwins Tree of Life, Haeckel's Embryo's, Archaeopteryx, Java Man....

Why must we keep these in the textbooks? And when are you going to replace them?

Just wanted to see if anyone can help with whether I have the right answers to these questions or not.

1) If the arteries are hardened resulting in blood reaching the capillaries at higher hydrostatic pressure, what effect wold this haveon the overall loss of fluid from the capillaries?

The overall loss of fluid would decrease as the fluid would be moving so fast that the fluid would have less time to pass out.


2) If the vein receiving blood frm a particular capillary was compressed (or partially blocked by a tumour) resulting in raising of the hydrostatic pressure at the venous end of the capillary, how would this effect the overall uptake of fluid by the capillary?

The overall uptake would increase as the fluid moving in the capillary would be moving slow enough that fluid could get back into the capillary.


Thanks in advance!

in adult humans, most cancers are carcinomas or adenocarcinomas involving various types of epithelial tissue cells. These include cancers of the skin, lung, colon, breast, and prostate. Why do you think that most cancers arise from epithelial cells?

I asked my teacher and he told me it had to do with their location and cellular process but i'm still confused

If humans drank only sea water, they would be unable to remove the excess salf from their bodies. Marine animals are able to remove excess salt because their loop of Henle is longer.
