Read each of the following descriptions of hypothetical species. Then indicate which mode of selection you predict will be in operation in this case, according to the following choices: 1. Directional 2. Stabilizing 3. Disruptive A species of snake feeds largely on amphibians, many of which produce chemicals in their skins that are distasteful or toxic. Individual snakes vary in the degree to which they can abide or resist the effects of these chemicals, and such resistance is a heritable trait. Over time, this will result in directional O stabilizing O disruptive selection.

Consider the effects of the same climate change scenario (+3°C) for a small frog with high cutaneous resistance, Litoria bicolor and cane toads Rhinella marina . The characteristics of the 3 species are show in the table below. The main differences among these 3 spreadsheets are the body masses and cutaneous resistances. Another difference is that, unlike Litoria caerulea, the other two species are assumed to be outside during the day rather than in a tree hollow. The wind speed inside a hollow is very low, and the humidity is higher. But the air temperatures are the same for all 3 models. Under the climate change scenario, were these 2 species exposed to lethal conditions for either water loss or body temperature? Species Mass (g) Cutaneous resistance (s/cm) Critical Thermal Maximum Temperature (°C) Litoria caerulea 50 14 37.5 Litoria bicolor 1 63 41.0 Rhinella marina 1, 50 or 500 1.7 37.5
I would like to know some examples of chemicals used by snakes like python or any other organism to defend or nurture themselves. I would also to read more about these chemicals; journals or texts references that provide information about these chemicals and organisms would be appreciated.

● How/Why might the COVID-19 quarantine have caused an increase in complaints of eye strain as well as neck and back pain?
As a qualitative researcher, you have been consulted to study the effects of COVID-19 on migrants. Identify the appropriate qualitative data collection methods you will employ in generating the data for your study and discuss two (2) challenges you might encounter
For your summer research project, you decide to repeat Lillian Tuttle’s (2017) experiment testing the effect of lionfish on other fish that are cleaners and clients. You do this new experiment at a new location (Bonaire), but use basically the same experimental approach and BACI design as Tuttle. a) You do not separate resident and transient clients (as Tuttle did), and below is a graph of your results showing the effect of the treatment on the total density of client fish in the community. Please explain your result. Imagine that you are planning to publish your experiment and that your answer to this question will be part of the “Results” section of your paper. Please do not worry about hypothetical statistical tests; just assume that the obvious patterns displayed in the graph can be interpreted at face value.
Considering a One Health approach, what do you think is the biggest challenge facing the future of parasitology?
As a municipal fisheries officer (MFO) you were assigned to investigate a report in the occurrence ofpoor breeding activities of fresh water tilapia in a barangay involved in tilapia aquaculture. It wasalso reported that the fry produced are weak and are always affected by fungal and bacterialinfection. You have ordered a blood and tissue analysis of the fry and the broodstock and the resultsare:• Prostaglandin in the blood of broodstock are low as compared to normal values.• Eicosanoids levels in the larvae were below the normal levels. 1. With these results, what major dietary nutrients would you order to be analyzed ?2. Wat major nutrients would you suspect is inadequate and are causing these problems. (Bearin mind that this is a freshwater fish.)3. Discuss what are the role of this/these nutrients in Fish breeding and immune responses.
