Explanation:

Just because DNA was found at the scene, that doesn't mean that the person there is actually guilty. For example, in a case where person B is guilty, a strand of hair from Person A could be carried over to another scene on Persons B's clothing.

Theoretically, how might researchers disrupt signal transduction pathways as possible treatments for cancer?
ivann1987 [24]

Answer:

d. disrupt the function of protein kinases involved in cell cycle regulation.

Explanation:

Protein kinases which are useful in cell cycles have major roles in the formation of tumors. So many of these protein kinases go through mutations. Cell cycles would be unable to be stoped and tumor would keep increasing.

A lot of receptors are G protein coupled. So it is going to be really helpful to alter and make G protein receptors to be inactive. Most if these kinases go through means of phosphorylation and dephosphorylation. Targeting these would cause disruption in signal transduction in cells with cancer

Tanya [424]

Answer:

Merkel’s disks: glabrous

Explanation:

Merkel's disks are nerve endings consisting of axonal branches that end in flat expansions and are implicated in the sensation of touch and pressure. Each of the nerve endings is associated with specialized epithelial cells. They can be found in the basal layers of the epidermis just above the basement membrane surface and are associated with rounded elevations of thick epidermis in the hairy skin. In addition, it is important to note that Merkel Disks are found only in glabrous skin and detect skin deflection.

!!AND!!

A non-polar molecule doesn't have anything in the molecule that cause it to be attracted to water or other polar molecules making it hydrophobic, like oil in water. 
A polar molecule has groups on it that give it a charge and cause it to be attracted to other polar molecules. Like alcohol in water. Alcohol is polar due to the -OH group attached to it causing it to miscible in water.
