Answer:
The correct answer is D. The outermost layer of a virion fullfills both protection and recognition functions of the virus.
Explanation:
A virion is a single viral particle. In this form the virus is physically isolable but without metabolic activity. Many virions can even be crystallized.
A virion, infecting a single host cell, is capable of producing thousands of descendants using the mechanisms of DNA replication, transcription and translation of the infected cell. This viral multiplication is often sufficient to kill the host cell by breaking it (lysandola).
Nucleic acid gives infectious power to the virion. It is enclosed by a protein wrap called capsid which is always formed by a number of individual proteins, called structural subunits. These subunits, associating in a specific way, form larger complexes called capsomeres. The set of nucleic acid and proteins is called the nucleocapsid of the virus, which can be enclosed by a membrane called pericapside envelope. Viruses without this membrane are called naked. Virus membranes are made up of a lipid bilayer, often associated with virus-specific proteins. The main function of the envelope is to help the virus enter the host cell. The surface glycoprotein serves to identify and bind to the receptor points in the host membrane. The viral envelope is then fused with the cell membrane, allowing the capsid and the viral genome to enter.
A step further down the evolutionary scale is the virino and below it the viroid and the prion; higher up is the virus.
Answer:
We should not build more power plants in France because of a few reasons. reason 1 carbon emissions are terrible for our planet and we already have enough pollution. reason 2 we have a very low fuel supply as it is and using it up for things we don't need is not sufficient. Reason 3 is money. France is in a debt of 3,403.24 euros. we should not be spending what we don't have. These are the reasons why we should not build power plants in France.

Answer:
The correct answer is ATP and NADPH
Explanation:
During the light reaction, the light energy is absorbed by the chlorophyll pigment present in the thylakoid membrane which moves through different electron acceptors and allows the formation of NADPH and ATP.
This ATP and NADPH get utilized into the Calvin cycle during carbon fixation, reduction and regeneration steps. This utilization converts ATP and NADPH into ADP and NADP+. The energy released by them is used to fix carbon to produce organic compounds. Therefore the correct answer is ATP and NADPH.
Smooth muscle cells have the greatest ability to regenerate.
