Even at temperatures as low as 75° F conditions can reach cautionary levels after two consecutive days. What relative humidity level must be reached for a 75° F day to reach the caution zone?

☐ 17. (07.08 MC) The prairie chicken was once widely seen in many areas across the Great Plains. Due to the conversion of prairie land into farmland, one species of the prairie chicken became extinct. The only species of prairie chicken left are endangered mainly because of habitat loss. They require tall grass prairies as their habitat. Which of the following is the best explanation for their endangered state? (4 points) The prairie chickens lack genetic diversity and resilience to changes in environment, resulting decline of the population. Environmental perturbations increased the rate of adaptive alleles. The prairie chickens have adapted to many new environments. The prairie chickens are genetically diverse and resilient to environmental perturbations.

The figure (above) shows the changes in vegetation cover along a 2 m vertical transect up the trunk of an oak tree (Quercus). Changes in the physical factors light, humidity, and temperature along the same transect were also recorded. From what you know about the ecology of mosses and lichens, account for the observed vegetation distribution:

39. Mites are common pests on individual fence lizards. Mites are observed to bite fence lizards to draw a blood meal, which increases mite population growth rates. Fence lizards respond by scratching their heads to remove mites. The population growth rate of fence lizards is not impacted by this interaction although it appears to be negative for the fence lizards that have mites. What is the best explanation to account for the population growth pattern in fence lizards.   a. the interaction is a +, - interaction b. the interaction is at the organism level c. the interaction is a altruism d. the interaction is at the population level e. the interaction is a mutualism

The tree is turned 90 degrees so that the branches are vertical instead of horizontal, but that is just a style preference of the authors. From this phylogenetic tree, when was Zika virus estimated to have emerged in South and Central America (including Brazil, Caribbean)? SA2 The branch lengths of the phylogenetic tree are scaled by time (time is on y-axis), the tips are positioned at their sampling date. Zika virus was sampled in Polynesia in 2013-January 2014 and these Polynesian samples are indicated in grey. Zika virus…
