Viral Spikies

Biology
1 answer:
kati45 [8]3 years ago
3 0

Answer:

B)attach specifically to host cell receptors

Explanation:

Viral spikes are one of the envelope proteins. These proteins are coded for by viral genes. Viral spikes project from the envelope surface. They are also called peplomers. One of the functions of these spikes is to specifically interact with the receptors present on the surface of the host cell to mediate the attachment of the virus to the host cell surface. Viral spikes and the host cell surface receptors are complementary to allow their specific binding. For example, the spike protein of the SARS-coronavirus bind specifically to the human host cell receptor ACE2.

<h3>What is speciation?</h3>

Speciation is the evolutionary process in which in populations of organisms come to being or evolve to become distinct species. The biologist Orator F. Cook made some Discovery and term it speciation in 1906when he performed experiment on cladogenesis, the splitting of lineages, as opposed to anagenesis, phyletic evolution within lineages.

Are insects intermediate host or definitive host? Are there any symptoms of gongylonemiasis? If the insects are the definitive h
Lemur [1.5K]

Answer:

They are intermediate hosts.

Explanation:

Disease-transmitting insects are called vectors.

The life cycle of disease-causing pathogens is closely linked to the biology of the insect that carries it.

 The symptoms of gongylonemiasis include  hemorrhagic inflammation  at the site the pathogen invades,  followed by  granulomatous tissue development that  produces nodules in the invaded organ.

Some diseases transmitted by insects occur in both humans and other mammals because our differences in anatomy and physiology are not very different.

It is unlikely that clinical symptoms will occur in humans if the insect were the definitive host, because our biology is quite different from their biology, and the pathogen would be adapted to fulfill its entire life cycle in their body.
