Has one extra chromosome in each cell (i.e 47 instead of 4.6). This is caused by one of the cell divisions during the formation of sex cells. Basically, the 21st chromosome ends up with 3 chromatids instead of 2. This is also why down syndrome is called trisomy 21.

5. It is one of the systems that is directly involved in maintaining the normal functions of cells. <em>d. nervous system</em>  

Explanation:

Neuron: Neurons are the structural and functional units in the nervous system.  Neurons transmit nervous impulses. These cells are formed in general by a cellular body, dendrites that are cytoplasmic extensions that receive stimuli from other cells, and an axon that is a long formation capable of conducting the electrochemical signals. Every neuron forms connections with other neurons. These connections are known as synapsis.

Peripheral nervous  system: Sense information is received by the peripheral nervous system and processed by neurons and synapses in the central nervous system. There are three types of neurons involved in this transmission: sensory or efferent neurons, interneurons, and motor or efferent neurons.

Spinal cord: The nervous system might be divided into the central nervous system and peripheral nervous system. There are two organs involved in the central nervous system that funtion as control centers. One of them is the brain, and the other organ is the spinal cord, surrounded by the vertebral column.  

Autonomic nervous  system: The autonomic nervous system is conformed by the sympathetic nervous system and the parasympathetic nervous system. It has too many functions in the organisms, controlling pressure, heart bitting, body temperature, sexual responses, urination, digestion, general metabolism, among others. It controls and regulates the whole organism.  

The nervous system: Homeostasis refers to stability, balance, or equilibrium. The organism needs to maintain homeostasis to guarantee the correct functioning of cells, tissues, organs, and so on. The homeostatic regulation is controlled by the endocrine system and by the nervous system, which acts as the control center.
