Answer:
(E) The two objects reach the bottom of the incline at the same time.
Explanation:
Given;
first object with mass, m
second object with mass, 5m
The acceleration of gravity for both object is the same = 9.8 m/s²
Since both objects have the same acceleration of gravity, and no external force due friction (frictionless inclined plane), they will reach bottom of the inclined at the time.
Thus, the acceleration due to gravity is constant for all objects regardless of their masses.
Therefore, the correct option is E;
(E) The two objects reach the bottom of the incline at the same time.

Correct answer choice is :
C) A jar with snails crawling on living plants
Explanation:
By using the power of sunlight, plants can change carbon dioxide and water into glucose and oxygen in a method described photosynthesis. As photosynthesis needs sunlight, this method only occurs during the day. We usually like to think of this as plants `exhaling in carbon dioxide and `breathing out oxygen. Gas transfer between Alveolar Spaces and Capillaries. The role of the respiratory system is to transfer two gases, oxygen and carbon dioxide. The transfer takes place in the millions of alveoli in the lungs and the capillaries that surround them.
Answer: False
Explanation:
The statement that the environment affects people, but people don't affect the environment is incorrect. It should be noted that people also affect the environment.
Some of our impact on the environment include pollution, deforestation, overpopulation, burning of fossil fuels etc. Thus has resulted in changes such as erosion, climate change, etc.
