Explanation:
Many scientists believe that RNA, or something similar to RNA, was the first molecule on Earth to self-replicate and begin the process of evolution that led to more advanced forms of life, including human beings.
The main causes of climate change are: Humanity's increased use of fossil fuels – such as coal, oil and gas to generate electricity, run cars and other forms of transport, and power manufacturing and industry. Deforestation
Volcanologists can predict eruptions—if they have a thorough understanding of a volcano's eruptive history, if they can install the proper instrumentation on a volcano well in advance of an eruption, and if they can continuously monitor and adequately interpret data coming from that equipment.
Answer: The correct answer is-
liquid to solid.
The term exo in exothermic means outside the system whereas thermic means heat.
Exothermic process can be described as any chemical reaction that liberates energy in the surrounding in the form of heat.
In other words, when heat is liberated in the environment in a chemical reaction, it is said to be an exothermic reaction/process.
When liquid phase changes to solid phase (such as water to ice), heat is released/liberated in the surrounding.
Thus, it is an example of exothermic process.

Answer:
the answer c. is correct
Explanation:
During DNA replication, the two parental DNA strands must be separated so that both strands can be copied. The resulting structure known as 'replication fork' is generated by helicase enzymes that break hydrogen bonds that hold DNA strands together, thereby the two strands of the DNA double helix uncoil at a specific location called the origin. DNA replication always proceeds in 5' to 3' direction. In consequence, a new DNA strand referred to as 'leading strand' is continuously synthesized because this strand grows in the same direction (5' to 3' direction) of the replication fork's movement, while other new DNA strand referred to as 'lagging strand' is synthesized discontinuously in short pieces called Okazaki fragments.
The answers are starch and sugar.
Carbohydrates are commonly known as sugars. They are compounds made of carbon, oxygen, and hydrogen atoms. Starch is a complex carbohydrate. Therefore, c<span>arbohydrates are found in foods that contain starch and sugar.</span>
