Suppose concordance data were collected from a cohort study of twins to study the genetic contribution to the onset of type 1 diabetes, also called juvenile diabetes. both monozygotic (identical) twins and dizygotic (fraternal) twins who grew up together in the same household were included. the concordance rate was found to be 68% among monozygotic twin pairs and 3% in dizygotic twin pairs. what general conclusion about type 1 diabetes can be drawn from these results?

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.

explanation:

answer: grassland biomes are closer to the equator and receive more rain.
