Answer #1

The sponges reproduce sexually and produce an larva. The larva is the juvenile stage of an organism that is structurally very different from the adult. In case of sponges the larval species are able to swim using tiny hair like cilia that beat repeatedly to move the organism through the water As the larca continue to develop in water they become structurally similar to adult sponges and lose their locomotive ability. At this point they settle and attach to a solid support where they compete development into adult stage

The advantage of the motile structure to the larva of to swim in the water an attachment to a place for the development into the adult

    Embryonic stem cells are undifferentiated “blank” cells that can form into any of the tissues present in humans. This makes them all-purpose cells. Because they can form any tissue, harvesting stem cells has become something similar to the holy grail, but harvesting them is fraught with great controversy. Stem cells have two important properties. If they are left in the dish, they will continue to multiply and form more stem cells. If they are placed in different growth conditions, they...

    1) What can you use fluorescence lifetime (FLIM) measurements for and what is the advantage compare with fluorescence intensity measurements? I have difficult to understand why FLIM is a better technique than fluorescence intensity? by better I mean the advantage FLIM have comparing to fluorescence intensity method? They say its better because FLIM is indenpendent of change in fluorescence intensity, and fluorophore concentration. But in FLIM measurement we measure the intensity of flourophore versus time? just like the fluorescence intensity...
