<span>Some scientists have presumed
that nature of life may exist with the choice
dictated by the local environment<span>. The primitive
earth illustrated the evolution of the
first heterotrophs from aggregates of organic molecules from the development of
heterotrophic forms according to the existing environmental conditions.</span></span>
The correct answer is As oceans get hotter, they release more CO2, which then increases atmospheric and ocean temperatures.
<span>
Positive feedback<span> is a process which can be explained like this: </span>A produces more of B which in turn produces more of A.</span> <span>In the example above, high-temperature oceans (A) produce CO2 (B) which then make temperature even higher (A).</span>
A BMI of 18.88 would be pretty normal for a 13 year old if not a bit on the lower side already. Usually we consider a BMI between around 18/19 and around 25 to be that of a normal weight person. If it is below theis, we would recommend to eat more, if ti above this we would recommend to eat less. Considering that we're talking about a 13 year old, perhaps it would be better if he/she ate a bit more to supply his body with the necessary nutritional needs.
I think the correct answer from the choices listed above is option b. A permeable rock weathers easily because it <span>contains many small, connected airspaces. Its porosity is very high that it can easily be destroyed by simple means. Hope this answers the question.</span>
Answer:
The pulmonary artery carries deoxygenated blood (blood whose oxygen content is relatively low) from the right ventricle to the lungs. The blood here passes through capillaries to alveoli and becomes oxygenated (as part of the process of respiration).
