Answer:
The sympathetic nervous system.
Explanation:
The sympathetic nervous system prepares the body to respond quickly to external stimulation or to situations that require alertness or strength, such as situations that arouse fear, anger, excitement or shame (situations of "fight or flight"). In this type of situation, the sympathetic nervous system stimulates the heart muscles to increase the heart rate and thus increases the rate with which oxygen and nutrients are sent to the blood, dilating the bronchi of the lungs (increases oxygen retention ) and causes the dilation of blood vessels that supply the heart and skeletal muscles (increasing the blood supply). The sympathetic system innervates the sweat glands and when the body is under situations of anxiety or stress stimulates them causing perspire to occur.
Answer:
The main function of the virion is to deliver its DNA or RNA genome into the host cell so that the genome can be expressed (transcribed and translated) by the host cell. The viral genome, often with associated basic proteins, is packaged inside a symmetric protein capsid.
Explanation:
what is a virus A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898, more than 9,000 virus species have been described in detail of the millions of types of viruses in the environment. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. The study of viruses is known as virology, a subspeciality of microbiology.
