Animal Circulatory Systems An efficient circulatory system has: a fluid, e.g., blood, to carry the materials to be transported; a system of vessels to distribute the blood; a pump to push the blood through the system; exchange organs to carry out exchanges between the blood and external environment, e.g., lungs and intestine to add materials to the blood; lungs and kidneys to remove materials from the blood. The most crucial demand on the circulatory system is the transport of oxygen and carbon dioxide to and from a gas exchange organ: lungs or gills and the tissues. All exchanges between blood and cells occur in the capillaries. The force of the pump that pushes blood through the arteries is dissipated as the blood flows through capillaries.

<h2>Answer </h2>

Lactic acid fermentation ocurrs in muscle cells when oxygen is in low supply

joja [24]

Answer:

1. My toaster doesn't toast my bread. --> Observation

2. Why doesn't my toaster work? ---> ask questions

3. There is something wrong with the electrical outlet. ---> Hypothesis

4. If there is something wrong with the outlet, my coffeemaker also won't work when plugged into it. ---> Prediction

5. I plug my coffeemaker into the outlet. ---> Experiments

6. My coffeemaker works. ---> Result of experiment

<em>Note: The question is missing some parts. The complete question is given below.</em>

<em>In the example below the scientific method is used to solve an everyday problem. Match each component to the appropriate step in the scientific method:</em>

<em>1. My toaster doesn't toast my bread.</em>

<em>2. Why doesn't my toaster work?</em>

<em>3. There is something wrong with the electrical outlet</em>

<em>4. If there is something wrong with the outlet, my coffeemaker also won't work when plugged into it.</em>

<em>5. I plug my coffeemaker into the outlet.</em>

<em>6. My coffeemaker works.</em>

Explanation:

The scientific method involves the following; observations, ask questions, form a hypothesis, make predictions, design experiment to test the hypothesis, obtain results, analyze results, draw conclusions.

1. My toaster doesn't toast my bread is an observation made by the person.

2. The person then proceeds to asks questions based on the observation; Why doesn't my toaster work?

3. The next step involves making a hypothesis to try to explain the observation; "There is something wrong with the electrical outlet"

4. A prediction is then made, which is an expected outcome if the hypothesis is correct; "If there is something wrong with the outlet, my coffeemaker also won't work when plugged into it".

5. Next, an experiment is conducted to test the hypothesis whether it is true or not; "I plug my coffeemaker into the outlet".

6. Results are obtained from the experiment which in this case is, "My coffeemaker works". The result is then analyzed to see whether it supports the initial hypothesis or not. Depending on the results, new hypothesis is made and further experiments conducted until a conclusion is reached.
