Genetics, double helix, cells
you didn't list choice but i'm guessing chloroplasts
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>
Lessen impacts of flooding by absorbing water and reducing the speed at which flood waters flow. Upstream wetlands can serve to store flood waters temporarily and <span>release them slowly downstream.</span>
<span>Parasites that live in the body are called endoparasites. An example of an endoparasite is a hookworm that lives in the hosts gut. </span>
