Carbon is released into the atmosphere only during the burning of fossil fuels
Explanation:
During the process of fuel burning, carbon is released in the atmosphere. The human invented power plants, factories, cars and other vehicles releases carbon in the form of carbon di-oxide in atmosphere.
However, the cellular respiration is similar to that of fuel burning as it is too a combustion process. But the carbon produced in this process fuels the inner cellular activities rather than releasing it in the atmosphere.
Answer:
Scientific theories are testable and make falsifiable predictions. They describe the causes of a particular natural phenomenon and are used to explain and predict aspects of the physical universe or specific areas of inquiry. For example the big bang theory
I don't know the given choices but I found an answer to the above question.
The answer is:
<span>No longer dividing cells of the mammalian brain. Post-mitotic cells will exit the cell cycle and will not contain cells in S phase.
</span>S-phase<span> -</span> part of the cell cycle in which DNA is replicated. Synthesis phase occur between G1 phase<span> and G</span>2 phase<span>.</span>
Q1) Bacteria are capable of converting atmospheric N in the form of N2 gas to NH3. this process is known as nitrogen fixation. N2 in the atmospheric form is not usable by other organisms, therefore specialised bacteria such as Azetobacter species are capable of carrying out this conversion from N2 gas into NH3 form that can be used by other organisms
Q2) Condensation.
Water in the gaseous state or known as vapour state converted to liquid state, process is known as condensation. in condensation the particles in water become more tightly packed and heat energy is removed from these particles reducing their kinetic energy thus becoming liquid state
Q3)
Transpiration declines
Deforestation is when the number of trees and plants have been cut down therefore numbers have reduced drastically, transpiration is the process in which water is transported through the plant and lost to the environment through evaporation. When the trees and plants have reduced the water lost by way of transpiration is also reduced. This impacts the water cycle as the number of water being cycled in the environment is lesser now.
Q4) the sun
sun is the major source of energy that facilitates the recycling of water in the water cycle. The sun causes water to be evaporated from water bodies and converted to water vapour. This water vapour is then recycled.
Q5) Plants can’t use Nitrogen in the form of N2
N is an essential element needed by plants, however plants cannot use up the atmospheric N2 gas. therefore bacteria are capable of nitrogen fixation that converts N2 gas into forms that can be used up and absorbed by the plants from soil.
