Scientists believe the earth is approximately 4 1/2 billion years old
The correct answer would be a hospital
Answer:
Sunlight.
Explanation:
Sunlight is responsible for proper functioning of stomata present on the leaves because the stomata only opens when there is sunlight and when the stomata opens, carbondioxide gas is absorbed by the leaves from the air while the water is taken from the roots which combines together to form glucose and oxygen. Glucose is stored in different parts of the plant while some oxygen is used by the plants in the process of respiration while the remaining oxygen is released in the atmosphere through stomata.
Explanation:
1. Donkeys have smaller hoofs than horses.
2.Donkeys do have longer and thicker ears than horses.
3.Horses tend to have a long and large face than Donkeys.
Sorry that's all I know

G-linked proteins are activated by odorants, as well as by sweet, bitter, and umami chemicals, though the specific action in the cell varies. Direct signaling pathways are triggered by sour and salt chemicals.
Gustatory receptors are found on the tongue's papillae and are utilized to sense flavor. The olfactory epithelium of the nasal cavity contains olfactory receptors. These are used to identify different odors. These receptors use sensory nerves to transmit sensory messages to the brain.
Gustatory receptors belong to the cells on the tongue that are specifically designed to perceive taste, whereas olfactory receptors refer to any of the nucleated, specialized cells of the mucous membrane of the nostrils that serve as the receptors for smell. So, the primary distinction between gustatory and olfactory receptors is this.
So, we can say that odorants, as well as sweet, bitter, and umami compounds, induce G-linked protein activities; however, the cellular response is different for each. Acidic and salty substances activate direct signaling pathways.
