yarga [219]

Answer:

Jaden's lack of sensitivity to poison ivy may be an inherited trait.

Explanation:

The poison ivy poisoning is due to the essential oils of this plant, mainly uroshiol, causing a reaction in the skin characterized by intense itching, redness and even burns with flicthenes, manifesting as an allergic reaction of varying severity.

Some people may have a low sensitivity or be insensitive to uroshiol, which does not rule out the possibility that they may become sensitive at some point in their lives.

The fact that Jaden and her father are insensitive to poison ivy venom may be an inherited trait, determined by a resistance to the allergic reaction the plant produces.

Regarding other options:

    <em><u>Environmental, acquired or learned traits</u></em><em>, do not determine the resistance to certain hypersensitivity or allergy reactions, which depends on each person's immune response or sensitivity.</em>
