Answer:
a, 8
b, 3
Explanation:
If the pedigree you are referring to is the one that is attached then the answer would be:
A pedigree shows how a trait is passed on throughout generations. Like it says in the question, the squares represent males. If the square isn't shaded in, then that means they are unaffected by the trait or normal. If it is shaded, they are affected.
All you need to do for the first question is count the number of squares you see in the whole pedigree. In this case, there are 8.
The second one is asking how many are affected, or have hemophilia. You need to count the number of squares that are shaded in. In the pedigree, we see 3.

Answer:
Release or egress
Explanation:
Virus can reproduce only within a host cell, this cycle of infection begins with the <em>attachment</em>, where the virus attaches to a specific receptor site on the host cell, after this comes the<em> entry,</em> 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 <em>replication and assembly </em>mechanism depending on its genome, finally, the last stage of viral replication is the <em>release or egress </em>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.

Answer:
The correct answer would be adaptive radiation.
It is a natural phenomenon by which ancestor species diversify into new forms as a result of adaptation towards changing the environment, limited or different resources, new challenges or new ecological niches.
For example, Darwin's finches faced new niches, different environment, different types of food resources due to which they adapt to different species bearing beaks of different shapes and sizes.
Ok so let me help you with this: Desertification is the process in which an environment becomes drier in climate, typically causing plant and animal life to decrease significantly. Researchers have found that areas around current deserts are becoming desertified, therefore expanding the desert.<span> Areas that may have once had adequate rain may now not receive much rain at all, causing desertification. I know this is going to be useful</span>
