Viruses are non-cellular infectious agents. The genetic information of a virus is surrounded by a protective coat made up of man
y protein monomers, called the capsid. The genetic component of a virus plus its capsid layer are collectively called the nucleocapsid. Which of the following accurately describe viruses?Select all the correct answers. A. Viruses have ribosomes to synthesize proteins.
B. Viruses are smaller than Bacteria and Archaea.
C. Viruses do not belong to any of the three domains: Bacteria, Archaea, and Eukarya. Viruses generate energy through mitochondria.
D. Viruses use facilitated transport to take in nutrients.
E. Viruses are as old as Bacteria and Archaea.

Ammonia is a highly toxic compound that is detrimental to one’s body. This toxic compound is often, and must be transformed into urea (uric acid) before being excreted from the body.
During the course of a continuous isometric contraction of given strength, the electrical activity progressively increases. This is due to recruitment of motor units taking place to compensate the decrease in force of contraction occurring in the fatigued muscle fibres.
