<span>Carbon enters the atmosphere as carbon dioxide from respiration (breathing) and combustion (burning). This then reacts in the atmosphere in the carbon dioxide cycle, increasing global warming as gases get trapped by the ozone layer. Autotrophs use energy from the sun and inhale CO2 to release oxygen through photosynthesis. Heterotrophs respire and are consumers of plant life, through cellular respiration, waste products are created, organism decay, dead organisms and their waste products then transform into fossils and fossil fuels used for energy resources and feed into the ocean uptake. The entire cycle creates a greenhouse effect on the planet and carbon and nitrogen gases become trapped in the atmosphere.

Animal, Plant and Root Respiration + Auto and Factory Emissions
=> CO2 cycle + sunlight => photosynthesis
=> organism decay, dead organisms + waste products
=> fossils and fossil fuels + ocean uptake
Answer:
B. Stabilizing selection
Explanation:
When natural selection acts against the extreme phenotypes but favors intermediate variants, it is called stabilizing selection. Stabilizing selection is mostly operative in the population s that are well adapted to the prevailing environmental conditions. Individuals with average or intermediate phenotypes are favored by stabilizing selection.
In the given example, the elk population maintains the antler size over generations. Most of the elks have intermediate-sized antlers while only a few have larger or smaller antlers. Since the average antler size (the intermediate phenotype) is favored over the extreme ones (larger or smaller sized antlers), the population is experiencing stabilizing selection.
Answer: The charges of the objects are A: Positive and B: Negative.
Explanation-
The electric field lines are pictorial representation of the electric field in terms of imaginary lines.
The direction of electric field is away from the positive charge and is directed towards the negative charge.
In this question, the electric field lines are emerging from A and coming towards B.
Thus, the right answer is A: Positive and B: Negative.
Metabolism
The metabolic processes in a cell determine its activity for conducting chemical reactions.
Answer: It’s called a point mutation.
