Effect of oxytocin on residual milk letdown and composition

Thesis - 4 pages - Biology

The Endogenous release of Oxytocin occurs in response to stimuli and mechanical release. Milk ejection is stimulated by the release of oxytocin from the posterior pituitary gland. The oxytocin then binds to the myoepithelial cells to squeeze milk out of the alveoli and ducts in the mammary gland....

Fruit abscission in physalis species in response to herbivory by heliothis subflexa

Thesis - 6 pages - Biology

Heliothis subflexa is a Lepidopteran caterpillar that feeds exclusively on Physalis spp. fruits. These fruits are encased in the inflated calyces—a characteristic that all plants in the genus Physalis share. Abscission of the fruits on which H. subflexa is feeding is a mechanism employed...

The use and abuse of biology

Essay - 1 pages - Biology

Although biology is useful it is not everything as it does not explain the motive of an individual. The motives of the individual may not be the motives of a society. In the example of war, the biological standpoint says that people go to war because there is an underlying aggression engrained in...
