ale4655 [162]

Your answer is...

<em>A benign tumor is a noncancerous group of cells that does not spread any harmful substances to the impacted area nor anything at all. It is safe compared to Malignant tumors and typically cause no harm to the body.</em>

<em />

Benign tumor:

Although it is noncancerous, if it is applying pressure to any vitals such as the blood vessels or nerves, it causes an obstruction. Thus ending up having to require treatment occasionally but not in all cases. It is considered a "good" tumor since it does not cause any pain or any problems when it doesn't apply pressure.

Malignant Tumor:

A Malignant Tumor is known as cancerous, or just cancer. These can be spread around the affected area of tissue or throughout the body. It is uncontrollably spread and disease ridden tumor that destroy the body tissue of the person. If this moves into the bloodstream, it can lead up to spreading within the lymph nodes, causing even more damage.

Kamila [148]

Answer:

Within the geological structure of Cayuga Lake Basin there is a diversity of limestone sources, which would make it possible for the lake to be a good location for the construction of a cement-making plant.

Explanation:

Cayuga Lake, part of the so-called Finger Lakes, located in New York, has an extension of about 40 miles. This lake is of great economic and ecological importance, because it allows fishing and recreation activities, besides being a place of passage for migratory birds.

The Skaneateles, Onandaga, Marcellus, Manilius, Moscow and Tully formations are an important source of limestone of variable quality, from which lime can be obtained for the manufacture of cement.

Although the presence of limestone would be ideal for building a cement-making plant, a project of this size should consider the environmental impact it could have.
