Answer:
The correct answer will be option
1. Oxygen
2. water.
Explanation:
Electron transport chain is the final step of the aerobic respiration which takes place in the inner mitochondrial membrane.
This chain helps in the formation of the ATP molecules as it is embedded with the ATP synthase.
The aerobic respiration is called the aerobic respiration as it uses the oxygen only in the final step of the ETS where oxygen combines with the free hydrogen ions to form metabolic water.
Thus, oxygen and water are the correct options.
Answer:
The immune system initiates inflammatory response while the immune response involves how this harmful substances are recognized and destroyed.
Explanation:
The inflammatory response is the normal response of the body's immune system to injuries to tissues by bacteria, trauma, toxins, that enter the body. Immune cells then quickly react to the damaged area to fix the problem because this area has become isolated separating the foreign substance from further contact with other body tissues. During the process, there may be symptoms like pain, warmth, swelling and redness.
The immune response involves how the body recognizes and and protect itself against foreign and harmful substances.
There has been a mutation and that mutation is a dominant trait. As both the parents have displayed the trait, there has been some reaction to the local environment that has improved or increased the survivabilty of the offspring related to this trait, so much so that the trait is now a characteristic that is dominant in the gene pool.
<h2>Mesophyll cells</h2>
Explanation:
The most distinctive characteristic of leaf mesophyll cells is that they are filled with many chloroplasts
Mesophyll cells constitute the main body of a leaf, occurring between upper and lower epidermis
Typically, the leaves of temperate-zone plants have two layers of mesophyll cells, the palisade mesophyll on the upper side and the spongy mesophyll on the lower side
The palisade mesophyll is a layer of densely packed, columnar cells which contain many chloroplasts, this layer is responsible for most of the photosynthesis of leaves
The spongy mesophyll is composed of large, often odd-shaped, photosynthetic cells separated from one another by large, intercellular spaces, these intercellular spaces apparently facilitate the exchange of photosynthetic gases
