The results of the study would be expected to change if the same experiment were repeated with natural gas in the area of a decrease in the reaction time.
<h3>What is Reaction time?</h3>
This is the time frame between when a stimulus and a response or total time taken for a reaction to occur.
Natural gas produces steady amount of heat with a higher temperature which leads to a decrease in reaction time.

<span>Ethics are human's comfort and interest,it cannot protect the environment so it causes damages to the environment where people will be affected.Nowadays Ethics are implemented to meet the needs of the current generation but it will be dangerous to the future generation.So that environmental crisis demand a new ethics which want focus on economic and social development,protective and caring environment.</span>
Answer:
A.All involve the active transport of gases across membrane
The leaf as a photosynthetic organ includes the following cells which contains chloroplasts
--> the palisade mesophyll
--> the spongy mesophyll and
--> the stomatal guard cells
Although all the green parts of a plant can be involved in the photosynthetic activities (with the exception of the root hairs), the leafs are the main organ of photosynthesis. Photosynthesis is the process by which green plants manufacture their food in the presence of sunlight. This takes place in the chloroplasts of these plant. Chloroplasts are structures that contains chlorophyll which traps in energy from the sunlight.
The mesophyll tissues are located between the upper and the lower epidermis of the leaf. The palisade mesophyll, which is found at the upper part, contains numerous chloroplasts and is the main site of photosynthesis in the leaf.
The spongy mesophyll is located at the lower part of the epidermis. They are irregularly arranged with air spaces between them which are linked to the stomatal openings. They also contain chloroplasts.
The stomatal guard cells are a pair of bean-shaped cells which controls the opening and closing of stomata. These cells contains chloroplasts which contributes to the movement of stomata.
Therefore the three different cells of the leaf that contains chloroplasts are the palisade mesophyll, the spongy mesophyll and the stomatal guard cells.
