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.
Explanation:
Basically it means that each virus is specific because of a certain cell makeup or cell membrane. Search up your question on google, there is a site I got this from! :)
Answer:
50%
Explanation:
Both parent's genotype is Bb because they are hairless and alive.
If it has a homozygous dominant genotype (BB), the dog will die in utero.
If it has a heterozygous genotype (Bb), the dog will be hairless but won't die.
If it has a homozygous dominant genotype (bb), the dog will have hair.
The ratio of BB:Bb:bb is 1:2:1 meaning that there is a 50% probability of having a live hairless puppy.
Hope this helps! <3
I’m assuming that this activity is about the Super Nova?, I can’t say I can help with that but what would help is looking up diagrams about, such as other examples, to see what the names of each part of the cycle/chart is?
C.interaction and attachment between myosin
Horses in the old times were smaller because of the softer grass to step on in the forests. However, as time passes, the living shifted to survival from the predators. This strengthens the limbs of horses and lifting the body from the ground in the process of running at great speeds. The answer here is D. <span>larger horses had longer legs and could run faster to escape predators.</span>
