Answer:
The functions of the skeletal muscles are affected by the CNS via the two sets of neurons, that is, lower motor neuron and upper motor neurons. The PNS comprises sensory neurons and motor neurons. The lower motor neuron is monitored by the upper motor neuron.
Hyporeflexia occurs because of the dysfunction of the lower motor neuron or its lesion. The lower motor neurons refer to the neurons, which innervate the skeletal muscles directly. Destruction to the central nervous system leads to hyper reflexes and destruction to the peripheral nervous system results in hyporeflexia.

Answer:
d. a system that enhances the destruction of bacteria through the activation of mast cells, lymphocytes, and phagocytes
Explanation:
Mast cells are white blood cells (i.e., lymphocytes) that form part of the immune system. These cells form part of the first line of defense against pathogenic organisms. Some of the most important phagocytic cells that function to protect the body by ingesting pathogenic agents (e.g., harmful bacteria) include mast cells, monocytes, neutrophils, macrophages and dendritic cells. In this regard, it is important to highlight that mast cells are similar to basophil granulocytes (another type of lymphocyte), and they are derived from hematopoietic stem cells.
Answer: <span>C.) Great white sharks have sharp serrated teeth for tearing into their prey.
Structure of teeth is highly related to the food an animal eats. For a carnivore, the animal whom eating meat, then sharp teeth is giving most benefit since meat is hard to cut. For herbivore, teeth with cutting ability will help much to cut the grass.</span>
