Answer:
A phenotype is the physical observations of anything, really. For example, lazuli bunting (a bird species) has feathers that range from dull brown to bright blue. the dull brown and bright blue birds are best at mating. adult males are aggressive toward the bluish-brown birds. The greatest frequency here is that 2 seperate colors are able to mate best, yet, the mixed birds are attacked.

Answer:
Hello, The DNA fingerprinting technique and development and comparison of physical fingerprints can be the methods used for the purpose of solving crimes and identification of missing person. The DNA fingerprinting can be done from the physical evidences such as blood, sweat, hair, tissues, teeth and other material obtain at crime scene. These can be compared with the suspects, victim and missing persons so as to establish their identity. The physical fingerprints can be developed on the scene of crime and compared with the requested specimen from suspect, victim and the missing person or in case of impersonation to establish the desired identity.

The earth's tilt of 23.5 degrees to it's axis as it revolves around the sun causes seasons; summer, spring, winter and autumn. This is due to the orientation of the earth with respect to the sun that cause variations in how to sun rays 'strike' the earth. Consequently, there are variations in temperatures across the earth, over its complete revolution, causing seasons my brotha, Hope this helps!
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).
