Virus are made with ADN or RNA only, which both of them has the information of replication. Once that the virus is in a cell, this ADN or RNA will be deposit inside the cell at the replication system that is going to make the virus reproduce unlimited times until the membranes of the cell break down. And they are useful because you can use them as a carrier or vector for treat diseases or for transgenics, bioterrorism, and so on.
The anwer is C. It makes more sence and is more mature.
Explanation:
K.E = 1/2mv²
1/2 x 7.26 x 7.5²= 204.19j
Answer:
A. passive transport by diffusion
Explanation:
Diffusion and osmosis are both types of passive transport. They do not require energy. Diffusion is the general term for the process. Osmosis is the diffusion of water molecules.
Many small, uncharged molecules can cross the cell membrane by diffusion. Oxygen and carbon dioxide are examples of two small molecules that pass the cell membrane by passive transport.
Larger or charged molecules require energy to cross the cell membrane. This is achieved by active transport.
