Answer:
The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.

Answer:
As you move from red to violet, the wavelength decreases and energy increases.
Explanation:
Here are the 7 from shortest to longest wavelength. Violet - shortest wavelength, around 400-420 nanometers with highest frequency.

Answer:
The correct answer is "Fist sequence; Fourth sequence; Second sequence; Third sequence".
Explanation:
Inversion of DNA is a process that often occurs during evolution of chromosomes. It occurs when the breakage of a chromosome in two places, results in the reinsertion of a DNA but in a reversed fashion. The evolutionary order of predecessors of inversion of DNA can be established by looking on the number of nucleotides that are different in the sequences of DNA. In this case, the first sequence is the ancestor and it haves the sequence "ABCDEF". The second in the evolutionary order is the fourth sequence since it originates from the first sequence only by changing the "BC" nucleotides to the end of the sequence "ADEFBC". The third in the evolutionary order is the second sequence since it still starts in AB, but has the other four nucleotides different: "ABFEDC". The last in the evolutionary order is the third sequence, which is completely different and reversed respect to the first sequence: "FEDABC".
Answer:
The correct answer is- Pharynx
Explanation:
Pharynx is a muscular tube that connects the nasal cavity to the larynx and oral cavity to the esophagus. A common passage is provided by pharynx for food and air.
Pharynx gets divided into three regions which are nasopharynx, oropharynx, laryngopharynx. Nasopharynx is the first portion of pharynx that connects the nasal cavity to it.
Oryngopharynx makes the middle portion of pharynx and acts as a passageway of food from mouth. Larygopharynx is the last portion that guides air towards larynx and food towards the esophagus. So the right answer is pharynx.
