Epithelial tissue is one of the four major tissue types in the body, acting as an interface between the body and the rest of the world.
Answer:
Conversion of forest to cropland or pasture decreases the rate at which carbon is taken up by plants.
Cut trees are often burned, and this releases carbon into the atmosphere.
Explanation:
First of all, <u>deforestation is the conversion of forests to non-forest uses. Non-forest uses include agriculture, industrial development, infrastructural development, etc. </u>
Forests are sinks for carbon and their removal or conversion to non-forest uses means that less carbon would be fixed through photosynthesis. Slash and burn agricultural practice also leads to the emission of carbon dioxide into the atmosphere.
Thus, more carbon dioxide would be present in the atmosphere as a result of deforestation and burning. This carbon dioxide is a greenhouse gas that causes the warming of the planet, a phenomenon that results in the change of climate of the planet.
<em>Hence, the conversion of forest to cropland leading to a decrease in the rate of carbon fixation and the emission associated with burning both contribute immensely to global climate change.</em>
Answer:
Symbiosis
Explanation:
Symbiosis is a physical association between two different organisms whereby both benefit from the relationship. A good example is the lichens. These are composite plants consisting of blue-green algae within the mycelial mass of fungus. The algae are provided with a means of attachment. They also obtain water, carbon dioxide and mineral salts from the fungus. The fungus obtains oxygen and carbohydrates made by algae through photosynthesis.
One of the most common conflict between human and machines that have arisen in the past and is still present up to today is the substitution of the machine to the jobs that could have been the source of income for the human beings.
