- To conduct their experiment, the researchers collected L. peronii eggs from a natural stream. After the eggs had hatched, tadpoles were raised in artificially constructed 2 L containers in a laboratory. All containers were filled with 1 L of filtered tap water, and the water was changed every other day. Thirteen tadpoles were placed in each container, and the tadpoles were exposed to a 12-hour light: 12-hour dark photoperiod. All tadpoles were fed thawed spinach daily. The researchers randomly placed the tadpoles into containers exposed to one of four treatments, with nine replicates of each treatment, as follows: Low UVBR (<6.0 kJ/m2), low temperature (15OC) Low UVBR (<6.0 kJ/m2), high temperature (26OC) High UVBR (>70.0 kJ/m2), low temperature (15OC) High UVBR (>70.0 kJ/m2), high temperature (26OC) The researchers recorded the number of tadpoles still alive out of the original 13 in a container (percent survival) at different time periods.

Question 17 options: A) True B) Falsearrow_forwardYou are a researcher studying birds in an Indonesian rainforest. You have just discovered two new species whose beaks are markedly different, which you have named Laetiphonia orthorhynchus and Laetiphonia rhamphis. In particular, the beaks of L. orthorhynchus are very long, straight and pointed, whereas L. rhamphis have beaks that are quite short, wide and curved downwards. In further studies, you find that the same gene codes for beak shape in both species. In your own words, explain at least two ways that changes in gene expression could result in the differences you observe between these two species. Make sure to be specific in how your explanation applies to the bird species in this example.arrow_forward
