In the lyric cycle, the virus attaches to the host cell which then injects its DNA. By using the hosts cellular metabolism
Explanation:
When cells asexually reproduce they split off from itself, and they have to replicate their DNA so both cells will have it because DNA is what tells the cell what to do, and how to work. The DNA will tell the cell parts all how to do their jobs, and will let the cell know when it should split off from itself. The DNA controls everything in the cell so without it the cell wouldn't know what to do.
Sympathetic nervous system under the Autonomic nervous system (ANS) is responsible for the physiological changes you experience when startled by a loud noise.
Autonomic nervous system (ANS) is part of the peripheral nervous system (PNS) and is responsible for control of vital functions.
ANS possesses three divisions, they are : Sympathetic nervous system (SYNS), parasympathetic nervous system and enteric plexus. Sympathetic nervous system is responsible for flight and fight responses.
SYNS also performs such tasks as relaxing the bladder, speeding up heart rate, and dilating eye pupils.
The ganglions associated with SYNS mostly arise from the thoracic and lumbar regions of the spinal cord.

The modern taxonomists classified organisms on the general basis of evolutionary, morphological, and genetic traits
Explanation:
- Evolutionary relationships provides the phylogeny of evolutionary ancestors and descendants
- Homologous structures are structures which look the same but perform different functions
, like bones of a human leg compared to bones on a bird's wing
- Analogous structures have different structure but same function like an insect’s and a bird’s wing
- Embryo developmental pattern and similar relationships
- Similarities in DNA and protein sequencing in related organisms
The above basis provided modern taxonomists to classify organisms according to the various disciplines like Genetics, Cytology, Embryology, Physiology, Anatomy and many more.
