<span>For a 20 month old child, a nurse may look for extremes in behavior to determine if the child is being abused. This includes being distant from parents or avoiding them, or being overly clingy. The child may act out or yell at any contact, or inconsolably cry beyond the point of a regular tantrum.</span>
Answer: C). A biozone can help trace the path of evolution over time.
Biozone is a stratigraphic unit which contains fossils in layers of strata existed in a particular geologic period. It is named as biozone because it depicts the number of biological taxa existed in particular strata. Therefore, the variation in features within taxonomic groups in biozones can give indication of evolution with respect to time.
Answer:
Electrical gradient.
Explanation:
Ions DO NOT move in Ion channels by simple diffusion because most ion channels can be:
I) selective of ions pass through it.
II) operating on a "open and close" principle. Where it opens or close on its own accord OR does so ONLY when induced by a specific influence like change in voltage of ion channels.
IN ADDITION to the concentration gradient, ELECTRICAL GRADIENTS (change in membrane voltage) affects the movement of ions through ion channels
Assume as what happens in a pot of water as it get heats.. hot becomes less dense, rises and cools, becoming more dense then sinks- that's called CONVECTION
So D- is the right answer
The gravitational force would increase, as the mass is increasing.
