Answer: C. The carbon cycle
Explanation:
The burning of the fossil fuel like coal will liberate carbon dioxide and carbon monoxide gases into the atmosphere. The carbon present in this gases circulates among the biosphere, hydrosphere, lithosphere and geosphere. Hence, burning of the fossil will affect the carbon cycle.
TrueFalse
C) proteins
D) nucleic acids
E) lipids, carbohydrates, proteins, and nucleic acids all consist of only macromolecular polymers
Answer:
(Correct option is B) Carbohydrates.
Explanation:
Biological molecules are known as the molecules which are found in the organisms, and play some important roles like development, cell division, and morphogenesis. They are necessary for the life.
Carbohydrates are known as the classes of biological molecules which consist of small molecules, and macromolecular polymers both. Carbohydrate are divided into three subtypes of essential macromolecules:
1) Monosaccharides: Fructose, galactose, and glucose are isomers of monosaccharide.
2) Disaccharides: Sucrose is the isomer of disaccharide.
3) Polysaccharides: Starch, cellulose, and glycogen are example of polysaccharide.
Glucose, and sucrose are known as the small molecules of carbohydrates, and other molecules of carbohydrate such as polysaccharides are known as macromolecular polymers.
Answer:
Crossing over
Explanation:
for variations which is one of the most important characteristic for Meosis
From the calculations, we can see that the length of the arc is 13.3 inches.
The arc is the portion of the circle that is bonded by two radii. Recall that the radius is a line drawn from the center to any part of the circumference.
Arc length = 2πr(C / 360)
Hence;
r = 2 * 3.14 * 8(95/360)
r = 13.3 inches
