The four types have different chemical structures and physical properties. The bad fats, saturated and trans fats, tend to be more solid at room temperature (like a stick of butter), while monounsaturated and polyunsaturated fats tend to be more liquid (like liquid vegetable oil)
On early earth, the one that was referred to as "Primordial Soup" is : B. The combination of organic compounds in warm salty water
Many speculated that these organic compounds mutated and evolved into a single cell organism, which became the origin of the organisms on earth
hope this helps
The best option for this question is: '<span>It increases the amount of runoff</span>'. Plant life acts as a barrier to the overland flow of water, thereby slowing the flow and allowing increased infiltration of water into the soil. Deforestation and overgrazing are major contributors to erosion, as plants act to bind the soil, and their removal allows the combination of looser soil and increased runoff to move masses of sediment into rivers and lakes. Deforestation will in fact decrease transpiration and percolation and precipitation rather than increase them.
Answer:
D. It is a random guess about how something happened.
Explanation:
In everyday life, a theory is a hunch or a guess about how something happens (in the scientific method, we might call it a <em>hypothesis</em>).
A is <em>wrong</em>. It doesn’t necessarily explain how nature works, because it hasn’t been tested by experimental testing and observation.
B and C are <em>wrong</em>. They are features of the <em>scientific method</em>.
