I got it wrong on connexus so i hope you dont make the same mistake i did ;-;
The situation would be that, in a sealed tube, there are 3 to 4 nails inside and a certain amount of calcium chloride was added. After three days, there will be no changes to be observed in the first tube since the oxygen is not enough to initiate a change and there is no presence of water. For the second test, the same situation is made but boiling water was filled in the tube. For this, no changes would still be observed since there is no moisture. For the last test, the same situation as the first but it is filled halfway with water. After 3 days, rust would be observed on the nails. In order for rust to happen, there should be water and oxygen. The oxygen in the early atmosphere of the Earth would react with iron present in the oceans thus producing iron ores.
Clean coal technologies, such as advanced coal-fired power generation and carbon capture and storage, can allow the world's coal resource to be used in ways that are compatible with environmental and climate goals. The correct option is C.
<h3>What is coal capture and storage?</h3>
Carbon capture and storage (CCS) is the process of capturing carbon dioxide (CO2) before it enters the atmosphere, transporting it, and storing it for centuries or millennia (carbon sequestration).
Clean coal technologies, such as advanced coal-fired power generation and carbon capture and storage, can allow the world's coal resource to be used in ways that are compatible with environmental and climate goals.
Thus, the correct option is C.

These primates have retained some primitive mammalian anatomical and behavioral traits, such as a strong sense of smell with an associated longer snout, eyes that are positioned more to the sides of the head, a smaller brain, a distinct breeding season and litters of offspring, nocturnal activity and the ability to synthesis vitamin C.
Cyanobacteria are primitive organisms where chloroplasts are believed to be originated. Now, with the theory of endosymbiosis, this suggests that these organelle from cyanobacteria was engulfed by other organisms which has helped them process light with the help of chloroplasts.
