Which statement is true about ocean thermal energy conversion (otec)? it is a mineral that contains one or more elements of economic value. it is the thinning of the stratospheric ozone that occurs over the poles in the spring. it is the use of temperature differences in ocean water to produce electricity. it is the process of obtaining information by using the senses.

The correct answer is: It is the use of temperature differences in ocean water to produce electricity.

Thermal gradients that are formed between warmer surface and colder deep water are used for energy production. That temperature difference is used to produce electricity and for desalination of ocean water. Difference between water levels must be at least 77o Fahrenheit to power a turbine.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

the unequal cytoplasmic division that  results  in  one egg  and three polar bodies ensures that a fertilized  egg has  ample nutrients  forits journey  to  the uterus.
