Answer:

The correct answer is c) opsonins

Explanation:

Opsonization is a process in which proteins like antibodies and complement proteins called opsonins bind to the antigens and get it recognized by the phagocyted which destroys the antigen.

Especially when bacteria is having external capsule than it becomes difficult for phagocytes to attach to the capsular surface as the recognition molecule like membrane carbohydrate of antigen is concealed by capsule.

So to encounter this, antibodies like IgG and complement proteins like C3b attaches to the antigen and get it recognized and opsonized by the phagocytes like macrophages. This opsonization causes the destruction of antigen by enzymatic lysis.

What is the Difference between DNA & RNA?
Travka [436]
DNA is deoxyribonucleic acid while RNA is ribonucleic acid !

DNA has base pair of adenine guanine thymine and cytosine.....while RNA has adenine guanine cytosine and uracil !

DNA is always double helix while RNA is mainly single helix !

DNA contains genetic info for 99℅ of organism while RNA is being catalytic and unstable than DNA is only present as genetic information holder in 1℅ !

DNA does not involve in protein synthesis directly but RNA has to !

Please help me I don’t understand it.
Irina18 [472]

Answer:

1) bay - 0%

  cream - 0%

  buckskin - 100%

2) cream - 25%

    bay - 25%

   buckskin - 50%

3) co-dominance

Explanation:

Ok so a run down on Punnett Squares,  all you have to do is put the parent's genes on the top and right hand side and combine those two genes in the middle as I did in the picture.  Now, co-dominance, this basically means that there is no dominant allele.  For example, imagine a white flower (W) and a red flower (R).  If these two plants were to breed, you would get a pink flower (WR).  This means the red allele and the white allele are both co-dominant.  It is basically a combination of both genes that result in a mixed phenotype of the two genes, aka red and white makes pink.  This is also how you get an AB blood type.

I hope this helps!
