One major aspect of animal life is the need to move as part of capturing food. One slight difficulty in this effort, however, is that the complex machinery required to make movement possible requires proteins maintained as specific temperature. choose one protein unique to animals you think is particularly important and do some research on what temperatures it can operate at Report the results here about it's response to temperature For one animal that uses that protein from part 1-what temperature range might they experience and is it possible the protein might leave it's optimal range (e.g) might a fish using said protein experience a large enough shift in environmental temperature to interfere with the protein functioning)? Under what circumstances might it experience this if true what strategy does the animal from part 2 use to make sure the proteins it requires stay at their optimal temp

All else being equal, a warm chameleon sitting on a sunny tree branch will experience a decrease in body temperature due to conduction if: O It changes color, and its new hue is a lighter color, reducing the amount of energy the chameleon absorbs from the sun. A cold breeze moves over the chameleon, transferring heat from the warmer chameleon to the cooler, moving ain. It opens its mnouth, allowing water to evaporate from its tongue and cheeks. The branch is cooler than the chameleon, and heat moves directly from the warmer animal to the cooler branch.
*our body is tightly regulated to maintain an internal (core) temperature of 98.6 degrees F. Your body does not function properly if you get too hot or too cold, partially because protein enzymes get too "stiff" (cold temperatures) or denatured (hot temperatures). If blood temperature rises too high, this is sensed by specialized neurons in the brain. They signal other herve centers, which in turn send signals toʻthe blood vessels of the skin. As these blood vessels dilate, more blood flows close to the body surface and excess heat radiates from the body. If this is not enough to cool the body back to its set point, the brain activates sweating. Evaporation of sweat from the skin has a strong cooling effect, as we feel when we are sweaty and stand in front of a fan. In this example, the brain is a(n): а. гесеptor b. control center nent C. effector eweet alands, are a(n):
Endothermic animals can maintain consistent temperature conditions by generating, main- taining, and regulating their body heat. Under cold conditions, more body heat becomes lost to the environment. Endothermic ani- mals rely on different mechanisms that allow them to maintain their body heat. Which of the following mechanisms that occur in endothermic animals does not describe a mechanism by which they maintain their body heat under these types of conditions? A B с D Some endothermic animals hibernate during extreme environmental conditions, which decreases the rate of metabolic reaction and decreases heat loss. The tissues of the blood vessels of many endothermic animals can dilate and move closer to the skin, allowing for heat to move more readily into the environment. Shivering, which can occur involuntarily in most endothermic animals, produces rapid muscle contractions, which increase the rate of cellular respiration and thereby increase heat production. Layers of densely packed…
SCIENTIFIC INQUIRY Female luna moths (Actias luna) attractmales by emitting chemical signals that spread throughthe air. A male hundreds of meters away can detect thesemolecules and fly toward their source. The sensory organsresponsible for this behavior are the comblike antennaevisible in the photograph shown here. Each filament of anantenna is equipped withthousands of receptorcells that detect the sexattractant. Based on whatyou learned in this chapter,propose a hypothesis toaccount for the ability ofthe male moth to detecta specific molecule in thepresence of many othermolecules in the air. Whatpredictions does yourhypothesis make? Designan experiment to test oneof these predictions.
Regulation of internal body temperature by animals O normally Involves constriction of blood vessels in the skin to lower temperature in a person in bed with a fever O is not very important except in primates O Involves many processes that vary greatly in different animal phyla does not involve the nervous system in any animals Ois always aimed at raising temperatures in ectotherms.

Imagine being on the TV show Survivor of the Smartest and you are stuck on an island with only a few tools. You are given a bow, 1 arrow, and two vials. One is labeled ‘Na Pump antagonist’ and the other is labeled ‘Na Channel agonist’. The arrows are to capture food, of course. You are an average shot! What will you coat the arrow tips with and why? Please, if you are not a meat eater then pretend that you can trade the meat for a bean burrito!

10. Which one of the following statements is true of the regulation of activities in the human body? J K L Hormones are always transported directly from a gland to an effector The interval between stimulus and response is usually greater if a message is transmitted by the nervous system rather than the endocrine system M Some processes are controlled by both the nervous and endocrine system 11. Oxytocin is a hormone that stimulates milk release during breast feeding. The diagram below shows the stimulus response model for milk release during breast feeding.
