What plant has been associated with episodic events of Cyclopia in sheep, goats and cattle?  

The phenotype of cyclopic lambs reminded scientists studying the loss of function mutants of the _________________ signaling pathway which showed craniofacial abnormalities including cyclopia that they may  both be caused due to a similar molecular mechanism. The phenocopy of teratogenic action of Veratrum californicum alkaloids with the above  genetic mutant phenotype eventually led scientists to pinpoint the role of cyclopamine albeit with integration of multiple fields. 

Which one of the following secondary metabolites, is not derived from the plant Veratrum californicum but instead derived from a fungus?

Ontogeny and Oncogenesis are intimately related, since signaling pathways that regulate normal development, are often misregulated in cancers.

It took both genetic and chemical approaches to establish Smoothened protein (component of the Hedgehog pathway) as the direct target of Cyclopamine action.

If a firm confronts a Perfectly Elastic demand curve, it means:

Suppose local government decides to reduce traffic congestion on the Cross-Town Bridge by imposing a $3.00 toll. The toll will be most effective at reducing the number of cars using the bridge if the demand for travel on the bridge is:

Suppose the government decides to increase the federal tax on gasoline in order to raise additional revenue to fund a new government program. Since raising the gasoline tax would increase the price of gasoline, the government must be correctly assuming that:

Suppose you are told that Publix Bottled Spring Water has a Price Elasticity of Demand (PED) coefficient of 3. The coefficient tells us that the quantity demanded of Publix Bottled Spring Water will increase by:

A wedding planner determines that one waiter can serve 10 guests, two waiters can serve 40 guests, three waiters can serve 100 guests, four waiters can serve 140 guests, and five waiters can serve 170 guests. The Marginal Physical Product (MPP) of the third waiter is:
