The correct answer to the question: What is calcareous ooze, would be: A fine-grained, deep ocean sediment containing the skeletal remains of calcite-secreting microbes.

Explanation:

The oceans are great reservoirs of different elements and different particles that are basic for life formation, life sustenance and ecological balance. Just as in other bodies of water, the ocean is also rich in sediments that are both carried by rivers, and deposited in them by thermal vents on their floors. These sediments, which are the result of depositions of different elements, and also of skeletons of dead microscopic beings, receive their names from the type of elements that these beings secrete. As such, we have calcareous oozes, that are given that name because of the presence of skeletal remains of microorganisms that secreted calcite, and which are present in deep ocean, far from land, as soft mud, or siliceous oozes, because the microorganisms deposited there secreted silica. In the case of the question here, since they are called calcareous, the name comes from the element calcite, and that is why the answer is the first one.  

well schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would  not be written on computer in this day and age.
