When we look at HEAD lice, we see (a) Lice from light and dark birds on feathers of light and dark birds (b) Mean luminosity of body and head lice from light and dark birds Luminosity score (mean ± std error) 225- 200 I O Lice from light birds ● Lice from dark birds - VS. Body lice (N = 16) p < 0.05 Head lice (N = 10) lower luminosity on light colored birds and higher luminosity on dark colored birds higher luminosity on light colored birds and lower luminosity on colored birds no differences in the luminosity between the two species on the two different birds

Please help with the following: Prior to approximately 12 KYA, humans were hunter-gatherers and relied on wild plants and animals for subsistence.

Please help me with the following question and make sure its 100% accurate pls Can parents distinguish their own children by smell alone? To investigate, Porter and Moore (1981) gave new T-shirts to children of nine mothers. Each child wore his or her shirt to bed for three consecutive nights. During the day, the shirts were kept in individually sealed plastic bags. No scented soaps or perfumes were used during the study. Each mother was given the shirt of her child and one shirt of another randomly chosen child. She was then asked to identify her own child’s shirt by smell. Eight of nine mothers identified their children correctly. Answer the following questions using a two-sided test and a significance level of 0.05.

1. Consider this graph on running speed in huskies Midosspring running speed (m/s) 16 14 12 10 8 + 2 Husky running speed 4 6 8 Midparent running speed (m/s) 10 12 14 16 a. Approximately what is the heritability of running speed in this kennel of huskies? (You can approximate by eyeballing from the graph, no need to calculate the actual slope) b. If the breeder where to selectively breed the dogs, will the dogs run substantially faster in the next generation? c. What else can the breeder do to increase running speed?
