Cells are the basic units of structure in living things
Two main functions of polysaccharides in living things are:
1. structural components
2. energy storage.
Those polysaccharides that are not easily broken down are used as structural components. Some of them are cellulose in plants and chitin in insects and crustacean.
On the other hand, starch and glycogen are easily broken down, so they serve as energy storage. <span>When energy is needed immediately, they break down to glucose and great amount of energy is released, </span>
Answer:
chemicals that cross the synaptic gap and bind to receptors on another neuron
found only in the central nervous system (the brain and spinal cord)
Explanation:
Neurotransmitters are defined as the chemicals that is transported from a nerve cell across the synaptic gap to the receptor of another neuron or a target cell such as a gland cell or a muscle cell.
Neurotransmitters are generated in the central nervous system (the brain and spinal cord) and are stored in synaptic vesicles.
"Hence, the correct answer is:
chemicals that cross the synaptic gap and bind to receptors on another neuron
found only in the central nervous system (the brain and spinal cord)".

While maternal intake and serum proteins contribute to the proteins synthesized in the breast tissue, the age of the infant will affect the composition of the breast milk as he or she ages. This is because of the reason that the demand for nutrients of the infant should be fulfilled until the recommended breastfeeding age of 2 years old.</span>
