Which statement about endotherms and ectotherms is correct?
ankoles [38]

Answer:

3.  Endotherms spend more energy on internal temperature regulation compared to ectotherms.

Explanation:

Ectotherms, are considered  as cold-blooded animals (reptiles and amphibians),  and are organisms that don't have the ability to generate enough heat to keep themselves warm. Endotherms, in contrast, do possess the ability to generate their own body heat.

Endotherms also called warm blooded animals  (mammals) have the ability to regulate their body temperature by themselves. If the endotherms are in a cold place their body increases the metabolism and generates more heat. This will compensate for the cold outside.

kobusy [5.1K]

Answer:

No. They will need to repeat their experiment several times, since the weather and times were different both days.

Explanation:

When a scientific experiment is conducted, one independent variable shall be changed in each experiment at a time so that the results of the experiment are authentic and we can easily determine which independent variable caused a change in the dependent variable.

If more than one independent variable is changed in the same experiment, then it will be difficult to interpret that which variable caused the change.

<u><em>Similarly, Maria and her brother need to repeat their experiment several times with just changing one variable at a time. </em></u>
