Explanation:
In the given question, the graph has been shown representing the change in temperature on Earth between 1900 to 1990. The graph has been made by plotting temperature ( °F) on y-axis vs Year on the x-axis.
From the graph, it can be observed that the temperature on Earth has increased over the years but between 1970 to 1990 the temperature has increased from 56.9 °F to 58.1 °F approximately.
The reason for this increase in temperature could be accounted to the fact that the burning of fossil fuels like petrol, gas, coal and others increased over these years which increased the amount of carbon dioxide and other harmful gases in the atmosphere.
Due to the increase in these gas, the greenhouse effect was observed and the temperature of the Earth begins to rise at an alarming rate.
Melting hope it helps

Rotational symmetry is radial symmetry which means that the shape is the same after several rotations. In five-fold rotational symmetry<span> the number of distinct orientations in which the object looks the same is five. </span>
Living organisms whose shapes have five-fold rotational symmetry are sea stars (starfish) and sea urchin. They <span>can be mapped onto itself through rotation about a central point by an angle of 2π/5. </span>
Answer:
When fuels burn they release heat energy and light energy to the surroundings in exothermic reactions known as combustion reactions

The most direct way to different types of epithelium tissue is by the number of cell layers and by the shape<span> of the cells. As for the layers, they can be simple, if there is only one layer of cells, or stratified, if there is more than one layer of cells. Related to the shape of the cells it can be a squamous epithelium, a cuboid epithelium, a columnar epithelium, or transitional when the cell can adopt different shapes so that the epithelium can be stretched.</span>
