Answer:
An identical setup but replacing the enzyme with an equal volume of water
Explanation:
When carrying out any experiment, it is important to set out a control in order to increase the reliability of the data and results.
The control minimizes the effects of variables other than the independent variable.
In the above experiment, starch has to be eliminated and replaced with water. Water does not have starch hence the digestive enzyme being tested will not have any effects making the data and results from the experimental group reliable.
Earth's temperature depends on the balance between energy entering and leaving the planet’s system. When incoming energy from the sun is absorbed by the Earth system, Earth warms. When the sun’s energy is reflected back into space, Earth avoids warming. When absorbed energy is released back into space, Earth cools. Many factors,
Answer:
The plant on the left does not accumulate significant photochlorophyll or carotenoids, so it will become very pale on the shoot tip, while the plant on the right will continue to grow upward as auxin is uniformly distributed around the tip of the right plant.
Explanation:
Phototropism is the orientation of a plant in response to light, either towards the source of light or away from light. Positive phototropism is growth towards light, while negative phototropism is away from light.
Auxin are substances that promote and regulate the growth and development of plants. Auxin escapes light making the area in the shade elongate more so the plant tip moves towards the light.
Answer:
The correct answer is option D.
Explanation:
Hamilton rules state that any trait that helps in benefiting others, B, is multiplied by genetic relatedness, R, which is greater than cot to self, C, it is favored by the process of natural selection.
As indicated by Hamilton's rule, the kin selection makes qualities increment in recurrence when the hereditary relatedness of a beneficiary to an actor multiplied by the advantage to the beneficiary is more noteworthy than the regenerative expense to the actor.
Thus, the correct answer is option D.
experiment, in the scientific method the hypothesis is tested through experimentation and if confirmed is called a theory.
