Most types of communication between cells utilize -chemical or electric signals.
Communication is done by the release of chemical signals by the cell thus sending the message. These chemical signals are usually proteins or other molecules that are produced by the sending cell. These signals are released into the extracellular space.
Answer:
d. all of the above
Explanation:
The diencephalon is a part of the brain located inferiorly and anteriorly to the corpus callosum, part of the telencephalon, and superior to the midbrain, delimited by the latter by an imaginary line that runs from the nipple to the posterior commissure (epithalamus). The diencephalon consists of: thalamus, hypothalamus, epithalamus, metatalamus and subthalamus. For this reason, we can conclude that the correct answer to your question is "d. All of the above".
Equator area: closest to the sun and hot and humid due to the mass evaporation from the excess heat.
Mid equator/south pole: somewhat mild, colder, probably mid-humid, depending on which end of the midsection you're going for
South Pole: cold and dry. Cold because it's naturally far away from the sun (like the north pole) and dry because there isn't significant water evaporation here and any that may form crystallizes into snow and ice.
