The mechanisms and the processes that occurs in the squirrels for raising their body temperatures. Given: The arctic ground squirrels were kept in the hibernating chambers by the researchers. These squirrels can build the burrows that can reach –10°C. The hibernating chambers in the laboratory were held at either +2°C or –12°C. It was observed that all the squirrels taken into consideration entered bouts of torpor repeatedly. The body temperatures (Tb) and the metabolic rates of individual squirrels were measured during the arousal time. The given table depicts the mean values of the metabolic rate and the temperature during the rewarming phase with their standard errors. The observation taken is for the two groups of squirrels at the different temperatures. Introduction: There are two types of animals: ectotherms and endotherms. Ectotherms have a constant body temperature, while the endotherms have to change their internal body temperature according to the temperature outside the body.

To analyze:

The mechanisms and the processes that occurs in the squirrels for raising their body temperatures.

Given:

The arctic ground squirrels were kept in the hibernating chambers by the researchers. These squirrels can build the burrows that can reach –10°C. The hibernating chambers in the laboratory were held at either +2°C or –12°C. It was observed that all the squirrels taken into consideration entered bouts of torpor repeatedly. The body temperatures (Tb) and the metabolic rates of individual squirrels were measured during the arousal time.

The given table depicts the mean values of the metabolic rate and the temperature during the rewarming phase with their standard errors. The observation taken is for the two groups of squirrels at the different temperatures.

Suppose you varied air temperature and measured oxygenconsumption for a female Burmese python without a clutch of eggs. Since shewould not show shivering behavior, how would you expect the snake’s oxygenconsumption to vary with environmental temperature?

Use the sources to answer the following question. Source A Black ladybugs with red spots are referred to as melanic, and red ladybugs with black spots are referred to as nonmelanic. Because dark objects absorb more heat, the melanic ladybugs are better adapted to keep warm at lower temperatures. Paul Brakefield studied a population of ladybugs in Tilburg, the Netherlands between 1980 and 2004. As the average temperature in the area increased over a period of twenty four years, he noticed that the percentage of melanic ladybugs in the population decreased. Source B - image Source C - image Part A: How genetic variation in the ladybug population increased the survival probability of some individuals and changed the population over time. Include evidence and reasoning.
