Answer:
Replicate itself into the cell host
Explanation:
Visus is made from a protein capsule and inside a fragment of RNA. Sometimes they also have some feet of filament to get attached to the cellular membrane.
Once attached, the virus injects its RNA into the cytoplasm and travels to the nucleus and insert this fragment of RNA into the cell DNA and start making copies of itself.
When the cell is full of virus, the membrane breaks and releases all the new virus to the neighbor cells, and the process starts again.
Answer:
The correct answer is: lets the air get inside the lungs.
Explanation:
The process of ventilation, or breathing, consists of two parts: <u>inhaling and exhaling.</u>
Inhaling is the name of the process that is responsible for the air entering the body by the respiratory tract. Exhaling is the opposite, it lets the air out. Both are equally important since they allow the gas exchange necessary for the oxygenation of the blood.
When inhaling, the diaphragm and the external intercostal muscles contract. This pulls the ribcage upwards and outwards, which increases lung volume while decreasing the air pressure inside.
D - Good conductors of electricity :)
