1. Scientists believe the missing carbon has found a sink in the Northern Forest. Scientist have come up with this idea because they believe consequences of global warming contributed to significant extent to the northern forest carbon sinking processes. In addition to that, scientists describe a process where the oceans of the world sink carbon to create a balance of the ecosystem. That is why they are not 100% sure.
2. Scientists are not sure concerning their idea about the whereabouts of the missing carbon because half of the emission stays in the atmosphere directly resulting to global warming with the remaining percentage absorbed by oceans and plants. The idea still offers room for discussion because it is observed that forest and savanna grass also contribute to carbon sinking though not all of the remaining percentage could be accounted in this manner.
3. Well, I believe in 2017, the carbon emissions were ranked the highest. The records indicate that this year recorded 45 billion tons of all global emission of the gas due to human activities. This figure could be argued from the fact that 2017 recorded a 2% rise in fossil fuel combustion. In a recent study on global emissions, China was identified as a major contributor to the growth of these emissions because of using coal as the major source of fuel.

Answer: See explanation
Explanation:
• Function of Iris?
The Iris simply regulates the amount if light that'll enter ones eyes.
• function of Suspensory ligament?
The sensory ligament maintains and also supports the eyeball's position within the orbit, while also preventing the eyeball's downward displacement of the eyeball.
• function of Yellow Spot?
A yellow spot refers to the area which can be found on the retina where there is beat vision. It is the part where maximum light falls
• Function of Choroid?
The choroid supplies nutrients to the outer retina and also maintains the volume of the eye and its temperature.
• function of retina
The retina receives light which is converted into neural signals, and this will then be sent on to the brain.
Answer:
Obsidian allows less crystal growth than basalt because it cools more rapidly than basalt.
Explanation:
Both Obsidian and Basalts are igneous rocks. Igneous rocks from the solidification and cooling of magma.
The textures of igneous rocks relies mostly on their mode of formation. Igneous texture refers to the way minerals are formed and arranged in rocks.
When magma forms and cools rapidly, crystals of minerals don't have time to grow. This leads to the formation of a rock that would look like glass. An example of such rock is Obisdian. Obsidian's glassy and smooth texture is as a result of the way it was formed. This rock type is an extrusive igneous rock that forms on the surface where cooling magma solidifies rapidly and crystals have little to no time to solidify.
Basalt on the other hand is an extrusive igneous rock. The mineral grains here have some ample time to form. Basalt is made of mafic minerals which impacts some very interesting textures on the rock mass. The texture of a typical basalt is fine grained and the minerals can be seen when magnified. Cooling is not as rapid during the formation of basalts compared to obsidian.
