Answer:
by conducting scientific experiment.
Explanation:
The effect of temperature on changes in flower color can be tested by performing scientific experiment. The temperature range will be independent variable and the variation in flower color will be dependent variable.
In this way the experiment will be done to see the result in order to prove the hypothesis.
Human evolution is similar to every evolution in the animal and plant kingdom. Forced by the environment both internal and external forces, animals adapted to the extreme conditions they were put in. As humans evovled, bacteria and other microorganisms also evolved to better attack and obtain food from other organisms including mankind.

Answer:
4. The given statement is false.
Correct statement: The pyruvic acid produced in glycolysis enters the mitochondria if oxygen is present in a cell.
Explanation: Pyruvate is transported into the mitochondria with the help of pyruvate translocase (transport protein located in the membrane of the mitochondria) where it is decarboxylated in order to produce acetyl-CoA.
5. The given statement is false.
Correct statement: In the matrix, pyruvic acid is converted to acetyl-CoA before the Krebs cycle begins.
Explanation: In mitochondrial matrix, pyruvate is decarboxylated to produce acetyl-CoA which enters the Krebs cycle.
Pyruvate is converted into lactic acid in the cytoplasm when cell undergoes lactic acid fermentation due to lack of oxygen such as in muscle cell.
6. The given statement is true.
Acetyl-CoA condenses with oxaloacetate (4-carbon compound) to produce citrate (6-carbon compound).
7. The given statement is True.
CO₂ is released as the byproduct of cellular respiration which is removed out of the body.
Other products such as NADH, and FADH₂ are used in electron transport chain which aids in the production of ATP.
