Answer:

Option C, buoyant force has to be greater than the weight of the object

Explanation:

As per Archimedes' Principle, buoyant force is the force exerted by water and it acts in the upward direction and is equal to the weight water displaced by the object immersed in water. Hence, there arises three situations -

a) When both the buoyant force and weight of the displaced liquid is equal, the object remains in stable condition and thus it remains submerged.

b) When weight of water displaced by the immersed object becomes greater than the buoyancy force exerted by water, the object sinks down.

c) When weight of water displaced by the immersed object becomes less than the buoyancy force exerted by water, the object rise up and floats.

Hence , Option C is correct.

The mechanism whereby an enveloped virus leaves a host cell is called

Levart [38]

Answer:

Release or egress

Explanation:

Virus can reproduce only within a host cell, this cycle of infection begins with the attachment, where the virus attaches to a specific receptor site on the host cell, after this comes the entry, in the case of enveloped virus, the envelope can fuse directly with the cell membrane to enter the cell, they can also enter through endocytosis. After entering the cell the virus initiates a replication and assembly mechanism depending on its genome, finally, the last stage of viral replication is the release or egress of the new virions produced in the host organism, some viruses can be released when the host cell dies, but some can leave infected cells by budding through the membrane without directly killing the cell.

I hope you find this information useful and interesting! Good luck!

in a series of experiments Griffith infected mi've with oa nonvirulent r strain bacteria and highly virulent s strain bacteria.

Andrej [43]

Answer:

This demonstrate the transforming principle.

Explanation:

Griffith performed the experiment on the virulent bacteria and non- virulent bacteria. The non- virulent bacteria produce rough colonies and did not cause pneumonia. The virulent bacteria produces smooth colonies that kill the mice and caused pneumonia.

When Griffith mixed the on virulent bacteria and heat killed virulent bacteria he found that the mice were killed. He concluded that there was transforming principle that turns the non- virulent bacteria into virulent bacteria from the heat killed bacteria. Something, has been transferred from the heat killed bacteria to the non- virulent bacteria. Later, he found that dead mice blood sample contained both the non-virulent rough bacteria strains and virulent smooth strains of bacteria.
