The level of medication in the bloodstream after a drug is administered is often modeled by a function of the form S (t) = A t p e k t S(t)=A t^{p} e^{-k t} S (t) = A t p e k t where A, p, and k are positive constants. The amnion can be found within the egg, as in lizards and birds, or the amnion can simply enclose the fetus within the uterus. The evolution of the extraembryonic membranes led to less dependence on water for development and thus allowed the amniotes to branch out into drier environments.

Translation of Cryobiological Techniques to Socially Economically This contrasts with external fertilization, which occurs in most fishes and amphibians. Bactrian camels are pregnant for 13 months, while dromedary camels are pregnant for 15 months. The lepidosaurs include modern lizards, snakes, and tuataras. How is frog, chick, and mouse embryonic development different? The hatchlings from amniotic eggs are more developed than that of amphibians, largely due to the vessels within the yolk sac allowing the transferal of nutrients. Urea can be concentrated in the synapsid kidney, and excreted with small bits of water. do camels have amniotic eggs Most reptiles reproduce sexually and have internal fertilization. Amniotes have an amniotic egg, which typically has a hard covering to prevent desiccation.
