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>
Answer:
Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope. They almost always consist of 4x, 10x, 40x and 100x powers. When coupled with a 10x (most common) eyepiece lens, we get total magnification of 40x (4x times 10x), 100x, 400x, and 1000x. To have good resolution at 1000x, you will need a relatively sophisticated microscope with an Abbe condenser. The shortest lens is the lowest power, the longest one is the lens with the greatest power. Lenses are color coded and if built to DIN standards are interchangeable between microscopes. The high power objective lenses are retractable (ie 40xr). This means that if they hit a slide, the end of the lens will push in (spring loaded) thereby protecting the lens and the slide. All quality microscopes have achromatic, parcentered, parfocal lenses.
