The sun. Greenhouse gases absorb heat better. So the more of these gases, the hotter it gets. However, the earth itself is naturally heating, but it goes too fast for live to adjust to the temperatures.

Photosynthesis uses energy from the sun to synthesize carbon-based molecules, that will serve as the energy for plants.</span>
1. Amphibians has moist slimy skin meanwhile fish has scales.
2. Fish uses gills for breathing, but amphibians are different. Young ones uses gills, but adult amphibians uses lungs and even skin for breathing.
Examples of amphibians include frogs and toads.
Both fish and amphibians are one of the 5 types of vertebrates under animals. Besides fish and amphibians, other vertebrates includes mammals, reptiles and birds.
Answer: Skin cancer
Explanation:
Melanin is a pigment derived from an amino called acid tyrosine. The most common form of melanin is called eumelanin, which is a polymer of dihydroxyindole carboxylic acids and their reduced forms.<u> When a person is exposed to the ultraviolet light (UV) from the sun, the melanocytes will produce eumelanin to prevent the skin from burning and damage to the cell nuclei (where DNA is found)</u> of the epidermis. This melanin production causes the skin to darken. The eumelanin in the skin then acts as a natural sunscreen by blocking the damaging effects of sunlight. So, skin darkens when exposed UV light, thus providing greater protection when needed by producing more eumelanin, but it also becomes more likely to develop melanoma, which is a type of skin cancer. This is because UV rays damage the DNA of skin cells. <u>The DNA (deoxyribonucleic acid) is the genetic material that has the instructios to the growth and functioning</u> of an organisms). Skin cancers begin when eumelanin protection is not sufficient and this damage affects the DNA of the genes that control the growth of skin cells. <u>This results in a tumor, which is the uncontrolled growth of cells </u>(in this case, skin cells) because there will be a mutation in DNA that affects the function of the cells.
