Virus life cycles ! fill in the blank diagram.

The virus life cycle consists of 6 stages:

1. Attachment: The protein on the virus capsid attaches itself to the receptors on the ell surface of the host.

2. Penetration: The viruses capsid goes through a conformational change, fusing the virus to the host's cell surface.

3. Uncoating: The virus nucleic DNA is released when the enzymes of the virus or host degrade the capsid of the virus.

4. Replication: Once released the virus DNA undergoes transcription or translation. The replication will be different due to the type of virus invading the host, example DNA virus, RNA virus or viruses with opposite nucleic acid polarity.

5. Assembly: Maturation process occurs, where by the replicated DNA and the virus protein are packed into virions in order to be released from the host.

6. Virion release: The virions can be released either through lysis or budding.

Explanation:

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther

explanation:

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
