What is calcareous ooze? what is calcareous ooze? a fine-grained, deep ocean sediment containing the skeletal remains of calcite-secreting microbes a fine-grained, shallow-ocean sediment containing the skeletal remains of calcite-secreting microbes a coarse-grained, deep-ocean sediment containing the skeletal remains of calcite-secreting microbes a fine-grained, deep-ocean sediment containing the skeletal remains of ooze-secreting microbes a coarse-grained, deep-ocean sediment containing the skeletal remains of ooze-secreting microbes

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.  

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
