Answer:

Both the PKA and IP3 levels increases. Hence, the correct answer is a and b.

Explanation:

Forskolin refers to a drug that increases the levels of cAMP or cyclic AMP by stimulating the enzyme adenylyl cyclase. The cAMP is an essential secondary messenger that ensures proper biological response of cells to hormones and other signals and also takes part in communication between the cells.  

When Forskolin increases the levels of cAMP, it will stimulate the enzyme PKA or protein kinase A and at the same time also enhances the intracellular concentration of Ca2+ and IP3 (inositol 1,2,5 triphosphate).

1) Alarm reaction stage

2) Resistance stage

3) Exhaustion stage

Note that the Alarm reaction stage consist of arousal by the autonomic nervous system, where several involuntary responses such as sweating, tension, raised breathing etc are observed due to hormones released.

Answer:

O founder's effect

Explanation:

A founder effect can be defined as the loss of genetic variation when a new population is established from a few individuals. This process is known to increase the frequency of particular gene variants (alleles) at different <em>loci</em> when they are selectively neutral (or nearly neutral), and thereby such genes are fixed by genetic drift (i.e., through the random sampling of founder individuals). Interestingly, it has been discovered that the majority of South American and Central American Indians are nearly exclusively in the O blood group, which has been further associated with random genetic drift and a founder effect.

Kamila [148]

Answer:

Within the geological structure of Cayuga Lake Basin there is a diversity of limestone sources, which would make it possible for the lake to be a good location for the construction of a cement-making plant.

Explanation:

Cayuga Lake, part of the so-called Finger Lakes, located in New York, has an extension of about 40 miles. This lake is of great economic and ecological importance, because it allows fishing and recreation activities, besides being a place of passage for migratory birds.

The Skaneateles, Onandaga, Marcellus, Manilius, Moscow and Tully formations are an important source of limestone of variable quality, from which lime can be obtained for the manufacture of cement.

Although the presence of limestone would be ideal for building a cement-making plant, a project of this size should consider the environmental impact it could have.
