Deoxyribose is the same as ribose but with two elements of oxygen add to it.
Intermediates in the first half of glycolysis are: Glucose - 6-Phosphate, Fructose- 6- Phosphate, Fructose-1,6-bisphosphate, Glyceraldehyde-3-Phosphate, Dihydroxy acetone phosphate.
Intermediates in the second half of glycolysis are: 1,3-bisphosphoglycerate, 3-phosphoglycerate, 2-phosphoglycerate, phosphoenolpyruvate.
Glycolysis is the process of breakdown of glucose that occurs in all the organisms of the earth whether aerobic or anaerobic. It is a 10 step process that occurs in the cytoplasm of the cell.
Phosphoenolpyruvate (PEP) is the last intermediate of the glycolysis process which converts into pyruvic acid by the action of the enzyme pyruvate kinase. This step results in the synthesis of 2 ATP. The compound's role can also be seen in photosynthesis in C4 plants.

Answer:
Both statements are true.
Explanation:
The simple columnar epithelium is characterized by presenting a single layer of cylindrical cells, with the basal and oval nucleus. This type of epithelium is found throughout the entire digestive epithelium, mainly on surfaces with high absorption power such as the walls of the small intestine, but they are also found on secretory surfaces such as the stomach walls, in the gallbladder, in some sections of the collecting tubes of the kidney, in the uterine tube (where it is ciliated) and in the uterus itself.
Squamous Stratified Epithelium is made up of basal cells that are cuboidal or columnar and metabolically active and superficial cells are flattened (squamous). Its function is to protect the underlying tissues in areas subject to nuclei abrasion, this epithelium (not keratinized) forms the wet surfaces of the basal esophagus, oral cavity and vagina. The oropharynx and the pharynx itself are lined by a stratified squamous epithelium as well.
Answer:
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life. Mitosis is the division of a cell into two daughter cells that are genetically identical to the parent cell. Meiosis is the division of a germ cell into four sex cells (e.g. egg or sperm), each with half the number of chromosomes of the parent cell. Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome. Mitosis gives two nuclei, and hence two cells, while meiosis gives four. Mitosis gives identical cells to each other and to the mother cell, while meiosis leads to genetic variation due to crossing over and independent assortment. Mitosis includes one division, while meiosis includes two.
No. Not all organisms. Because in a way fish are organisms and there are some that live way down in the deep dark water. And they cannot swim up to where the sun is or they would disintegrate. So the answer would be no, not all organisms depend on the sun for energy. Different organisms have different ways of getting energy.
