The three main parts of a nucleotide are a phosphate group, a five-carbon sugar (deoxyribose in DNA or ribose in RNA), and a nitrogenous base.
Phosphate Group: This is one of the essential parts of a nucleotide. The phosphate group consists of a phosphorus atom bonded to four oxygen atoms.
It provides a negatively charged backbone in the DNA or RNA molecule, contributing to its overall structure and stability.
Five-Carbon Sugar: The second vital component is a five-carbon sugar molecule. In DNA, this sugar is deoxyribose, while in RNA, it is ribose. The sugar forms the central part of the nucleotide structure and serves as a link between the phosphate group and the nitrogenous base.
Nitrogenous Base: The third crucial part is the nitrogenous base. There are four nitrogenous bases in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G). In RNA, uracil (U) replaces thymine.
The nitrogenous base is responsible for the genetic code and base pairing in DNA (A pairs with T, and C pairs with G).
Therefore, all three components—phosphate group, five-carbon sugar, and nitrogenous base—are integral to the structure and function of nucleotides. None of them can be considered "not one of the main three parts" of a nucleotide.

Besides, mitochondria,vacuole and nucleus
"cell membrane - the thin layer of protein and fat that surrounds the cell. The cell membrane is semipermeable, allowing some substances to pass into the cell and blocking others.
centrosome - (also called the "microtubule organizing center") a small body located near the nucleus - it has a dense center and radiating tubules. The centrosomes is where microtubules are made. During cell division (mitosis), the centrosome divides and the two parts move to opposite sides of the dividing cell. The centriole is the dense center of the centrosome.
cytoplasm - the jellylike material outside the cell nucleus in which the organelles are located.
Golgi body - (also called the Golgi apparatus or golgi complex) a flattened, layered, sac-like organelle that looks like a stack of pancakes and is located near the nucleus. It produces the membranes that surround the lysosomes. The Golgi body packages proteins and carbohydrates into membrane-bound vesicles for "export" from the cell.
lysosome - (also called cell vesicles) round organelles surrounded by a membrane and containing digestive enzymes. This is where the digestion of cell nutrients takes place.
mitochondrion - spherical to rod-shaped organelles with a double membrane. The inner membrane is infolded many times, forming a series of projections (called cristae). The mitochondrion converts the energy stored in glucose into ATP (adenosine triphosphate) for the cell.
nuclear membrane - the membrane that surrounds the nucleus.
nucleolus - an organelle within the nucleus - it is where ribosomal RNA is produced. Some cells have more than one nucleolus.
nucleus - spherical body containing many organelles, including the nucleolus. The nucleus controls many of the functions of the cell (by controlling protein synthesis) and contains DNA (in chromosomes). The nucleus is surrounded by the nuclear membrane.
ribosome - small organelles composed of RNA-rich cytoplasmic granules that are sites of protein synthesis.
rough endoplasmic reticulum - (rough ER) a vast system of interconnected, membranous, infolded and convoluted sacks that are located in the cell's cytoplasm (the ER is continuous with the outer nuclear membrane). Rough ER is covered with ribosomes that give it a rough appearance.
smooth endoplasmic reticulum - (smooth ER) a vast system of interconnected, membranous, infolded and convoluted tubes that are located in the cell's cytoplasm (the ER is continuous with the outer nuclear membrane). The space within the ER is called the ER lumen. Smooth ER transports materials through the cell. It contains enzymes and produces and digests lipids (fats) and membrane proteins.
vacuole - fluid-filled, membrane-surrounded cavities inside a cell. The vacuole fills with food being digested and waste material that is on its way out of the cell." I quote from my science paper. It was exhausting! But I know all this so I added some extra.
Answer:
Explanation:
the color of the leaves would be different (red, purple, yellow, etc.) and they would most likely fall off of the tree
This inheritance is termed as Incomplete Dominance.When a red bird and blue bird mate the result is a purple offspring.This is because neither of the two colors are expressed.This type of a cross results in formation of a new colored offspring here it is purple.Incomplete dominance is a trait in which an intermediate offspring is formed because one allele is not completely expressed over the other paired allele.The resulting offspring is formed with characters that is a combination of both of their parents character.
is the second stage of photosynthesis
does not require light
all of the above if u would help wich one would it be
Answer: Calvin cycle is the second stage of photosynthesis and does not require light.
Explanation: Photosynthetic reactions are divided into two phases: light dependent reactions and carbon fixation reactions. Light dependent reactions is the first stage of photosynthesis in which sunlight is used to split a molecule of water and the energy generated is conserved in form of ATP and NADPH.
Calvin cycle is the second stage of photosynthesis. It is also called carbon fixation reactions. These reactions do not need light to occur. It occurs in the dark, the ATP and NADPH produced in light dependent reactions are used to drive these reactions. In Calvin cycle, carbon dioxide is assimilated through a cyclic pathway to produce triose phosphate which is a precursor for glucose and other related molecules such as starch.
The Calvin cycle is the second stage of photosynthesis.
The correct statement is the second stage of photosynthesis. The Calvin cycle is a series of reactions that occur in the stroma of chloroplasts in plants. It takes place after the light-dependent reactions and uses the energy stored in ATP and NADPH to convert carbon dioxide into glucose. This cycle does not directly produce water and does not require light.
Also known as the Calvin-Benson cycle, is a series of biochemical reactions that take place in the stroma of chloroplasts during photosynthesis. It converts carbon dioxide and energy from ATP and NADPH into glucose and other organic molecules. The Calvin cycle is a crucial part of the light-independent reactions of photosynthesis.
