Answer:
B. The carbon cycle
Explanation:
In the carbon cycle, carbon in the atmosphere is absorbed into plants, where the plants use photosynthesis to convert that carbon into oxygen and energy for themselves. Neither of the other cycles involves a plant taking in a gas directly from the atmosphere.
Hopefully this was helpful! :)
we aren't given options but in order from longest to shortest it is radiowaves, microwaves, infared,visible light, ultraviolet, x rays, gamma rays
Answer:
Hemoglobin is an iron-containing protein present in the blood that functions for transportation of oxygen to different body cells..
Each hemoglobin molecule have tetrahedral structure consist of four heme groups surrounded by a globin group. Heme, is composed of porphyrin (ringlike organic structure) which is attched to an iron atom. There are four iron atoms in each molecule of hemoglobin that binds with four oxygen atoms and globin carry two linked pair of polypeptide chain.
The oxygen reversibly binds with the polypeptide chain and the process called oxygenation.
The best kind of model for the scientist to use is an interactive model of the planets' orbits on a computer.
<h3>What is the law of orbits?</h3>
Kepler's first law, also known as the law of orbits, describes the shape of planetary orbits. According to this law, the planet's orbits around the Sun are elliptical, despite having very small eccentricities.
For this reason, it is necessary to know all the orbits of the planets in an interactive way, since according to Kepler's law, the orbits decrease over time.
