Answer:
Water's extensive capability to dissolve a variety of molecules has earned it the designation of “universal solvent,” and it is this ability that makes water such an invaluable life-sustaining force. On a biological level, water's role as a solvent helps cells transport and use substances like oxygen or nutrients.

<h2>Ecological succession</h2>
Explanation:
An area with bare rock or a disturbed site with no vestige of its former community undergoes secondary succession while an area recovering from forest fire undergoes primary succession.
-False.
Ecological succession that takes place in an area which was formerly inhabited by living organism gots disturbed or barren due to some natural calamity is called secondary succession.
In the given question both the cases reflect that the area which was experiencing succession, was formerly inhabited by living communities. So in both the cases secondary succession is taking place.
Explanation:
Adenomatous genes are most often found among neoplastic genes and are the target of 2/3 of all colon members. The factors of risks associated with its onset include advanced age, sedentary lifestyle, male gender and increased BMI / abdominal fat. Dysplasia gives it the potential for malignancy, constituting the precursors of most, however, only 5% of adenomas evolve to carcinoma by a process that runs from 7 to 10 years, with the greater risk of progression for advanced adenomas. Adenomatous polyps can be classified into 3 subtypes based on epithelial architecture:
Tubular adenoma: represent about 80% of all adenomas and are characterized by the presence of tubular glands in at least less than 75% of the architecture.
Villous adenoma: account for 5 to 15% of all adenomas and have glands with villous projections in at least 75% of its architecture.
Tubulovillous adenoma: correspond to 5 to 15% of adenomas and has mixed histology with less than 75% of both types of architectures.
High-grade dysplasia is characterized by a complex architecture where there are grouping and glandular irregularity as well as a cribriform pattern and cytological atypia, with loss of nuclear polarity, enlarged nuclei with nucleoli, atypical mitoses, and prominent apoptosis. The high-grade dysplasia has a higher risk of developing for carcinoma
