Answer:
antigen-MHC protein complexes
Explanation:
Helper T-cells recognise antigens that are complexed with MHC proteins and interact with target cells. Antibodies can be produced against a single antigen in a variety of ways. Toxic shock syndrome is a relatively mild condition that resembles other minor allergy responses. Antigen-presenting cells break down superantigens.

*Given
Percent of the wolves which are female - 55%
Percent of the wolves which hunt 
     in medium-sized packs                      - 20%
Percent of the wolves which are both
     female and hunt in medium-sized
     packs                                                  - 15%
*Solution
<u>Assuming that there is a total of one hundred wolves in the species, </u>
1. Since percent (%) means "per 100" or "for every 100" then, 
a. The number of female wolves is
    (55 female wolves / 100 wolves) * 100 wolves total = 55 female wolves
b. The number of wolves that hunt in medium-sized packs is
    (20 wolves / 100 wolves) * 100 wolves total = 20 wolves
    Note that the 20 wolves is a mixture of male and female wolves. 
c. The number of female wolves that hunt in medium-sized packs is
    (15 female wolves / 100 wolves) * 100 wolves total = 15 female wolves
2. Because there is a total of 55 female wolves in the species, and 15 of these wolves hunt in medium-sized packs, then the number of female wolves that do not hunt in medium-sized packs is, 
 
    55 female wolves total - 15 female wolves hunting  = 40 female wolves not
                                                in medium-sized packs         hunting in medium
                                                                                              sized packs
3. To find the proportion, we can express the answer in terms of percent (%) or in fraction, which is usually how proportions are expressed. 
For every 100 wolves, there are 40 female wolves that do not hunt in medium-sized packs. This can be expressed as a proportion of 
 
                                       <span> <u> 40  </u>
</span>                                        100
and simplified by dividing both the numerator and denominator by 10, we get,
                                     <span><u> 40/10  </u>
</span>                                     100/10
                                       <span><u>  4   </u>
</span>                                        10
When this is expressed in percent, we multiply the fraction or proportion by 100% to get, 
                                       <span><u>  4   </u>   x    100%     = 40%
</span>                                        10
Thus, the proportion of female wolves that do not hunt in medium sized packs is 4/10 or 0.4. When expressed as percent, this is 40%.
