Hemoglobin is involved in the transport of other gases: It carries some of the body's respiratory carbon dioxide<span> (about 20–25% of the total</span><span>) as </span>carbaminohemoglobin<span>, in which </span><span>CO2</span><span> is bound to the globin protein. The molecule also carries the important regulatory molecule </span>nitric oxide<span> bound to a globin protein </span>thiol<span> group, releasing it at the same time as oxygen.</span>
The correct answer is - B. The countries cannot produce enough food to feed their own people.
The countries of Central America do not have sufficient amount of arable land for agriculture to produce for themselves, and also to export, especially not to be exporting on a large scale. Despite this, the large landowners that control most of the arable land, are exporting most of the products to other countries. They do this for getting bigger profit, even though the people in the countries don't have sufficient food for eating, they don't really care because they have enough money to have enough food on the table, while the ordinary citizen suffers from malnutrition.
A. Cooperation between governments and citizens

Fossilization is a process that requires certain conditions so that it can take place. The climate is very important, a hot and wet place is not a place where there's a chance of finding fossils, while the places with permafrost are a much better candidate because the bacteria can not dissolve the organisms. The pressure also can play a vital role. A place that manages to keep the organisms safe from outside influence, like the tar pits, are excellent preservers. Also the structure of the organisms play a key role, a boneless organism is very hard to preserve and be fossilized, while an organism with bone structure has a bigger chance of being preserved.
Answer:
Viscosity directly affect the speed of convictions.
Explanation:
The speed of convection in Earth’s mantle, oceans, and atmosphere also depends on the viscosity of the fluids. If the viscosity of fluids is higher so it takes more time to complete the process of convection in Earth’s mantle, oceans, and atmosphere, while on the other hand, if there is lower viscosity of fluids, the conviction in the mantle, oceans, and atmosphere of earth occur in high speed due to easily movement from place to place.
