Answer:
The energy is mostly released as heat through the dog's activities; the nutrients either become part of the dog's body or are released to the ecosystem as wastes like urine, feces, and exhaled gases.
Explanation:
- The food that is consumed by an organism is digested and the nutrients obtained from the food are partly absorbed by the digestive system and assimilated and stored into the body and the nutrients that are not absorbed are released in the form of feces.
- The chemical energy obtained from the food is released in the form of heat through the activities that are done by the dog.
- The independent variables are temperature, airflow, and light and the dependent variable in each of the experiments is evaporation.
- The schematic representation in the diagram helps in the understanding of the setup for the experiments.
- The level of temperature, the rate of airflow, and the intensity of light must be controlled in the experiments.
- A person will not be confident in experiment 3 results as the temperature is the independent variable that alters the results of evaporation.
<h3>What are the four foremost factors of a managed test?</h3>
When possible, scientists take a look at their hypotheses through the use of managed experiments. A managed test is a systematic take look at executed below-managed conditions, which means that simply one (or a few) elements are modified at a time, even as all others are saved consistently. We'll appear carefully at managed experiments within side the subsequent section.
- In the three experiments, the dependent variable is evaporation, as it changes with the change in another variable.
The independent variable in experiment 1 is temperature, experiment 2 is airflow, and experiment 3 is light.
- The experiment can be understood better with the representation of the schematic that shows the setup to analyze how the experiment was performed. Therefore the diagram must add the schematic of the experiment.
- The controlled items in the experiment are the variables that are set at the particular unit to form the result. the controlled item in experiment 1 is temperature, experiment 2 is airflow from the fan, and experiment 3 is the intensity of light.
- The result of experiment 3 is based on the dependence on the intensity of light keeping temperature constant and controlled. If the temperature is not controlled in the experiment then it may lead to an alteration in the results as it depends on both light and temperature.
- The flow chart for the increase in pressure affecting the evaporation is given in the image attached.

Answer:
Malleable and ductile properties indeed help minerals useful. Both properties are useful because they help in transforming the shapes of minerals. Malleability is a useful property since it can be flattened or pounded by a hammer. Also, the ductile property makes it possible for the minerals to be stretched in the form of a wire. These two properties makes it useful for minerals.

Answer:
1. Using the map and the minimal knowledge that Liz has at this point, propose three different hypotheses regarding the sudden high mortality of marine iguanas. Record your answers in the worksheet and post your hypotheses to the 03.01 class discussion board before proceeding to the next question. (3 points possible)
Hypotheses One: Iguanas are adapted to hot/warm weather, so the weather changed could have affected them.
Hypotheses Two: There was not enough shelter for the iguanas so they started disappearing.
Hypotheses Three: A new species has come close to where the iguanas live and taken them out.
2. Look at your classmates’ hypotheses on the discussion board. Choose one hypothesis that seems most likely to you. Provide the student name and hypothesis and tell what evidence you would need to support (or refute) it. (3 points possible) Carter Spiers, Hypothesis 1. there was a lot of rain and it washed at the iguanas away. We would have to dive into the water/ ocean and find iguana bodies to be able to prove that this is true.
3. Given what you know at this point about marine iguanas and the abiotic effects of ENSO, develop two possible directions of research that Liz should pursue to understand exactly why the iguanas suffered such a high mortality. Keep in mind that you need to consider indirect effects. While environmental temperature does change metabolic rates of ectotherms, the iguanas are exposed to a wide range of temperatures as they feed and bask on the lava. Direct mortality in response to a temperature change of a couple of degrees is unlikely. (3 points possible)
Possible Research Direction One: The climate event caused a lot more rainfall which then made it very hard for the iguanas to reach their food source.
Possible Research Direction Two: The temperatures raised very high causing the iguanas to absorb a extreme about of extra heat, which eventually made them very lazy and stopped defending their self from predators.
4. Choose one of those directions of research and determine what data you would need to find to support your ideas. (2 points possible) Specific data of the extreme amounts of rainfall.
