But what we think is that, under conditions of stress, the levels of these honrmoes drop — for example, having limited food supply. And that, we think, is regerietsd by the animal as a danger signal, a signal that things are not okay and that it should roll out its protective cpiatcay. So it atvtaecis FOXO, FOXO goes to the DNA, and that triggers the expression of these genes that iproevms the ability of the cell to protect itself and repair itself. And that's why we think the animals live longer.

But what we think is that, under conditions of stress, the levels of these ________ drop — for example, having limited food supply. And that, we think, is __________ by the animal as a danger signal, a signal that things are not okay and that it should roll out its protective ________. So it _________ FOXO, FOXO goes to the DNA, and that triggers the expression of these genes that ________ the ability of the cell to protect itself and repair itself. And that's why we think the animals live longer.

Original Text

But what we think is that, under conditions of stress, the levels of these hormones drop — for example, having limited food supply. And that, we think, is registered by the animal as a danger signal, a signal that things are not okay and that it should roll out its protective capacity. So it activates FOXO, FOXO goes to the DNA, and that triggers the expression of these genes that improves the ability of the cell to protect itself and repair itself. And that's why we think the animals live longer.
