Here are more the Three:
Most of the increase in global temperatures since 1950 has been caused by human activity.
The United States is the second largest contributor to carbon dioxide (CO2) in our atmosphere
As global temperatures increase, our societies will find it harder to adapt to the changes this brings, and some species are more likely to go extinct
The concentration of carbon dioxide (CO2) in our atmosphere, as of May 2020, is the highest it has been in human history.
NASA data show that average global temperatures in 2019 were 1.8 degrees F (0.98 degrees C) warmer than the 20th century average. In fact, the five warmest years in the 1880–2019 record have all occurred since 2015
Global warming puts coral reefs in danger as the ocean warms, scientist fear that coral reefs will not be able to adapt quickly enough to the resulting changing conditions, and bleaching incidents and diseases will increase
Answer:
Potassium (k)
Explanation:
Potassium is so reactiev that it wont even be found naturally in nature, it legit racts with almost anything and doesn't take almost anything at all to start a reaction. COmpared to the other Potassium is easily number 1
Chromatography is a simple technique in principle, it remains the most important method for the separation of mixtures into its components. It is quite versatile for it can be used to separate mixtures of solids.
Explanation:
- The two elements of chromatography are the stationary phase and the mobile phase. There are many choices of stationary phases, some being alumina, silica, and even paper. The mobile phase, in liquid chromatography, can also vary. It is often either a solvent or a mixture of solvents and is often referred to as the eluant.
- A careful choice of eluting solvent helps to make the separation more successful. The mixture is placed on the stationary phase. The eluant passes over the mixture and continues to pass through the stationary phase carrying along the components of the mixture.
- Chromatography is used in industrial processes to purify chemicals, test for trace amounts of substances, separate chiral compounds and test products for quality control. Chromatography is the physical process by which complex mixtures are separated or analyzed.
- Chromatography is based on the principle where molecules in mixture applied onto the surface or into the solid, and fluid stationary phase (stable phase) is separating from each other while moving with the aid of a mobile phase

Answer: reproductive, endocrine, and nervous systems
- Hormones provide feedback to the brain to affect neural processing. Reproductive hormones affect the development of the nervous system. The hypothalamus controls the pituitary gland and other endocrine glands.
