Sex Chromosome Biology in the Mammalian Kingdom All biological
... All biological differences between women and men originate from the sex chromosomes. Some 160 million years ago, the X and Y chromosomes were very similar, but since then the Y chromosome has lost most of its genes, whereas the present X chromosome contains more than 1000 genes. Hence, the dosage of ...

Gas Exchange/Alveoli
... Gas exchange is the uptake of O2 from the environment and the discharge of CO2 to the environment. It is necessary to support the production of ATP in cellular respiration. Alveoli are the vehicle by which some organisms perform gas exchange, typically because they are too large or complex for direc ...

Organisms at high altitude
.jpg?width=300)
Organisms can live at high altitude, either on land, or while flying. Decreased oxygen availability and decreased temperature make life at high altitude challenging. Despite these environmental conditions, many species have been successfully adapted at high altitudes. Animals have developed physiological adaptations to enhance oxygen uptake and delivery to tissues which can be used to sustain metabolism. The strategies used by animals to adapt to high altitude depend on their morphology and phylogeny.
