Answer:
Sphenoid bone spans the width of the cranial floor; keystone of the cranium because its central wedge articulates with every other cranial bone. Unlimited access.
Explanation:
The correct answer is that "the T cell enters a state of anergy".
The activation of T cells requires two signals: (1) antigen specific signal presented by an antigen presenting cell (either a macrophage or a dendritic cell) that activates t cell receptors and (2) co-stimulatory signals that is not antigen specific but rather found in the plasma membrane of the antigen presenting cell (i.e. CD28). In the absence of a co-stimulatory signal, the t cell will enter a state of anergy or the inability to produce an immune response toward an offending antigen.
Answer:
Lateral Hypothalamus
Explanation:
According to the hunger researchers' initial assumption lateral hypothalamus is that part of the brain which regulates intake of food and metabolical activities like metabolical regulation of peptides like the orexins melanin-concentrating hormone. It is that part of the brain that plays a key role in the ingestive behavior regulation.
The lateral hypothalamus system initiates physical and cognitive processes like it promotes arousal and feeding behavior, metabolism, regulates body temperature, BP, etc. and when stimulated it results in the feeding behaviour in animals as they begin to eat.
Diffusion is the passive transport from a high concentration to a low without using energy. homeostasis results from balance.

<h3>What is Ozone?</h3>
Ozone is a trioxygen molecule; contained in the upper atmosphere with a sole aim of protecting biological life against ultraviolet rays of the sun. The ozone layer is however depleted to Oxygen molecule in the lower atmosphere.
