Process, transmit, and receive nerve impulses (electrical signals) from periphery to central nervous system.
Answer:
The most appropriate answer would be A sperm cell fertilizes an egg cell.
In sexually reproducing organisms including plants, life starts as a single-celled zygote which is formed by the fertilization of sperm and egg.
The zygote then divides through mitotic division to form an embryo.
After fertilization In angiosperms, the ovule matures to form seed and ovary matures to form fruit.
In gymnosperms, zygote develops into a new sporophyte.
The answer would be D) The growing population is taxing Earth’s resources which could lead to the extinction of many species (I just got this right)
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).
