Answer:

Explanation:

Yes, the disease specialist's explanation is plausible based on what we know about evolution by natural selection. Let me break it down for you in simpler terms.

The disease specialist is suggesting that the tropical fungus mentioned by your colleague might be related to the fungal pathogen causing the illness at the hospital. They explain that even though the tropical fungus may have been brought to Vancouver Island some time ago, it might not have caused any illness until now. This could be because the tropical fungus was originally adapted to a different environment and couldn't infect people in the new environment of Vancouver Island.

Now, here's where evolution by natural selection comes into play. Over time, organisms can undergo changes in their traits and abilities through a process called natural selection. Mutations, which are changes in the genetic material of organisms, can happen randomly. If a mutation occurs in the tropical fungus that enables it to infect individuals in the Vancouver Island environment, it could be favored by natural selection.

For example, let's say that due to a mutation, the tropical fungus developed adaptations that allowed it to thrive in the new environment and infect people. These adaptations might include changes in its ability to penetrate human cells or evade the immune system. As a result, the fungus would become more successful at causing infections in the Vancouver Island population.

So, the disease specialist's explanation is plausible because it suggests that over time, through natural selection acting on mutations, the original tropical fungus could have evolved adaptations that made it capable of causing illness in the new environment of Vancouver Island.

The citrus industry in Florida is facing a new threat from an invasive butterfly species called the Asian citrus psyllid. This insect is known to transmit a deadly citrus disease called "huanglongbing" or citrus greening.

The psyllid feeds on citrus trees and injects the bacteria that causes citrus greening. The disease causes the fruit to be bitter and misshapen, eventually killing the tree. Citrus greening has already caused significant damage to the citrus industry in Asia, Africa, and Brazil, and has been present in Florida since 2005.

However, the recent detection of the invasive butterfly, which feeds on citrus trees and damages the fruit, has raised concerns about the potential for the disease to spread even more rapidly. The butterfly, which is native to Southeast Asia, has already caused significant damage to citrus trees in California, and experts are warning that it could have a similar impact in Florida if not controlled.

Researchers are working to develop new strategies to combat the spread of both the butterfly and the disease, including the use of biological control methods and the development of resistant citrus varieties. However, the scale of the challenge facing the industry is significant, and there are concerns that the long-term impact on Florida's citrus industry could be severe.

Explanation:

Tree pollen is a common hay fever trigger. It’s the first pollen to be released during hay fever season, and levels are typically highest from late March to mid-May.

Around 95% of people’s hay fever is triggered by grass pollen, which tends to be highest between mid-May and July. In fact, there’s strong evidence that when grass pollen levels are high, people with asthma are more likely to need hospital treatment.

Hay fever can also be triggered by weed pollen, which is highest from the end of June until September.

Know your pollen triggers

You can be allergic to more than one kind of pollen across the year. Different pollens are released at different times, but our changeable weather makes it hard to predict exactly when. If you have hay fever symptoms all year round you might have non-allergic rhinitis.  

If you regularly get hay fever and take antihistamines, start taking them up to four weeks before you normally get symptoms. Starting them early means that when pollen starts being released, the medication has already built up in your bloodstream so you may be less likely to react.

If you usually use a steroid nasal spray, it can take up to two weeks to start working, so again, start using it before your personal pollen trigger is released.

Cytotoxic T cells recognize the foreign transplants through the difference in class I MHC molecules on the cells. The correct option is A.

Cytotoxic T cells are known for their property of attacking the foreign cells and thus serve as the first line of defense against the transplants. They attack the foreign cell of a transplant if they recognize it as foreign. The following explains the reason and method of recognition:

Option A: Presence of different class I MHC molecules on the graft

The Cytotoxic T cells can recognize the difference between self and non-self cells by the identification of MHC molecules on the cells. The MHC molecules act as a label on the surface of every nucleated cell in the body. Every nucleated cell has the Major Histocompatibility Complex molecules that distinguish self from non-self cells. Thus, when there is a transplant, the Cytotoxic T cells recognize that the transplant cells do not contain the same class I MHC molecules as the host cells, which makes it easier for them to target the foreign cells.

Option B: Presence of different class II MHC molecules on the graft

The class II MHC molecules are found on antigen-presenting cells. They are responsible for presenting foreign antigens to T cells and then activating them. However, cytotoxic T cells recognize the foreign cells through class I MHC molecules instead of class II MHC molecules. So, the option is incorrect.

Option C: Presence of different complement factors on the graft

Complement factors are also involved in the immune response, but they do not help the Cytotoxic T cells recognize the foreign cells. Thus, the option is incorrect.

Thus, we can conclude that the cytotoxic T cells recognize the foreign transplants through the difference in class I MHC molecules on the cells. Answer option A.
