The tumor which grows slowly and is surrounded by membranes that prevent it from spreading from the original site is <u>benign tumor</u>
<u>Explanation:</u>
Benign tumor is normally surrounded by membrane which will be identified by the doctors due to their protective sac. They are abnormal growths found in the body. They are normally not malignant and doesn’t spread to any other parts.
It is normally found as a mass of tissue in any part of the body which can be found as a lump. It can be removed safely by operating it.

Answer:
The statement that is true about leukotrienes is that they create excess mucus in the airways (last option).
Explanation:
Leukotrienes are inflammatory mediators, derived from arachidonic acid, in whose presence occurs increased vascular permeability in tissues, leading to inflammatory processes.
The presence of leukotrienes has been related to the development of allergic reactions, mainly in the respiratory tract, producing edema in the mucosa, contraction of the smooth muscles of the airways and increased production of mucus
in the airways.
the other options are not correct because leukotrienes:
- <em>Produce contraction of the smooth musculature around the airway.
</em>
- <em>Are related to the production of bronchial asthma.
</em>
- <em>Are inflammatory (chemical) mediators. </em>
