Answer:
Evolution is a process that results in changes in the genetic material of a population over time. Evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species.
Explanation:
Answer to Question 1:
True
Explanation
As indicated in the passage, fruiting bodies of fungi differ structurally. However, different species can appear to be similar and often misleading thus creating the risk of food poisoning.
Question 2:
Many experiments require student-supplied items, such as _____.
1. Chicken
2. Fresh flowers
3. Distilled water
4. All of the Above.
Answer to Question 2:
The correct answer is 3.
Explanation
Water comes in varying degrees of purity. When water that contains other substrates or impurities is used for an experiment, it distorts the results and creates errors. So the scientist's ability to determine the root of a problem becomes enervated.
Using distilled water impurities removes the possibility of such an error. Distilled water is also used for cleaning laboratory equipment.

The controlled experiments are performed by the scientists, when they want to study the changes in the sample on changing a single variable. So, the correct answer is option (b).
In case, all variables are kept same, no changes would be observed in the experiment sample. A controlled experiment can be performed on living thing as well as non living. But, controlled experiment cannot be performed on the things which are influenced by a lot of variables, as they cannot create realistic results. So, the option (a), (c), and (d) are incorrect.
Thermal energy/ heat energy
