7 0

Each person carries 23 pairs of  chromosomes in every cell that makes up their body, with the exception of gametes, which contain 23 SINGLE chromosomes. So when a sperm and egg meet, they then have 23 pairs. In the process of meiosis 'crossing-over' occurs, which means that the chromosomes get "shuffled". This means that the child can receive random traits not only from the parents, but also the grandparents. so there is about  2⁴⁶ possible pairings, excluding the risk for things such as Down-Syndrome

Which description of synapses is not correct? which description of synapses is not correct? second messengers can activate gene
LiRa [457]
The incorrect among the choices is "<span>direct signaling involves the activation of g proteins"

This is incorrect because direct signaling does not involve the activation of g proteins rather it involves the activation of ion channels resulting to either an excitation reaction (depolarization of the membrane) or an inhibition reaction (hyperpolarization of the membrane); and this will ultimately affect the action of the organ the nerve is innervating.</span>
