Answer:

A virus attaches to a specific receptor site on the host cell membrane through attachment proteins in the capsid or via glycoproteins embedded in the viral envelope. The specificity of this interaction determines the host (and the cells within the host) that can be infected by a particular virus.

Answer:

Capsid proteins interlock with a receptor site on the host cell.

The capsid protein and host cell receptor interlock like a puzzle piece.

Viruses vary in shape to attack the various types of receptors on cells.

The shapes of viruses include polyhedral, helical, enveloped, and complex.

Once the virus attaches to the host cell, it invades the cell and hijacks the DNA of the cell.

nasty-shy [4]

Answer:

25000 fragments

Explanation:

A restriction enzyme can cut a random DNA sequence once per every 4^n where n = number of bases in the recognition site of enzyme.

There are 6 bases in Xbal's recognition site (TCTAGA) so it will cut once per every 4^6 = 4096 bases (4kb).

Total genomic size = 100000kb

So expected number of fragments = Total genomic size/Size of one fragment

= 100000/4

= 25000 fragments

<h2>Elk forested Area Avoid Riverbanks</h2>

Explanation:

  • Predators clearly can impact the size of prey species populaces through direct mortality, which, can impact all out scavenging pressure on explicit plant species or whole plant networks  
  • Predation hazard can likewise have populace ramifications for prey by expanding mortality, as indicated by the "predation delicate nourishment" theory  
  • The Gros Ventre River, which depletes around 600 square miles of eastern Jackson Hole and the mountains more remote east is the biggest waterway on the asylum. The generally wide stream diverts are vigorously meshed in territories where geologic materials are of low erosional opposition, just like the case on the shelter. The various rock bars in the river channel have next to zero vegetative spread, thus, of yearly flooding and disintegration
  • Hence, the right answer is "Elk tend to avoid riparian areas and wooded riverbanks"
