Answer:
NO. Mitosis involves one set of nuclear division and results in two nuclei that are exactly the same as the original. On the other hand, meiosis involves two sets of nuclear divisions.
Explanation:
Mitosis is a type of cell division normally occurring at the sites of growth and development of new tissues and also at sites of repair. It also occurs during asexual reproduction of organisms. Each mitotic cell division is a process that follows distinct phases.
Each mitotic division results in the formation of two daughter cells which are genetically identical to the parent cell, that is they have the same number and type of chromosomes as the parent cell.
During telophase, a nucleolus develops in the nucleus of each daughter cell. The cytoplasm divides in the process called cytokinesis. An invagination develops and finally splits the cell into two daughter cell each with its own nucleus and cytoplasm.
Answer:RNA polymerase synthesizes an RNA transcript complementary to the DNA template strand in the 5' to 3' direction. It moves forward along the template strand in the 3' to 5' direction, opening the DNA double helix as it goes.
Explanation:
Answer:
D.all lipids contain fatty acids.
Explanation:
A.Lipids are fats, like oil, that are insoluble in water. ... The most abundant class of lipid molecule found in cell membranes is the phospholipid. The phospholipid molecule's polar head group contains a phosphate group. It also sports two nonpolar fatty acid chain groups as its tail.
B.The simplest definition is a lipid as any molecule that is insoluble in water and soluble in organic solvents. Most lipids are soluble to some extent in organic solvents such as hexane, ether, chloroform or benzene. They constitute a complex collection organic compounds that include fatty acids, (A,D, E and K).
C.There are two major types of lipids- simple lipids and complex lipids. Simple lipids are esters of fatty acids with various alcohols. For eg., fats and waxes.
D.Not all lipids have fatty acids. The operational definition of a lipid is a biomolecule is that is sufficiently hydrophobic to be more soluble in an organic solvent than in water. The common theme to their structures is a high percentage of hydrocarbon character.
E.Most lipid hormones are steroid hormones, which are usually ketones or alcohols and are insoluble in water. Steroid hormones (ending in '-ol' or '-one') include estradiol, testosterone, aldosterone, and cortisol. ... Amino acid-derived hormones and protein hormones are water-soluble and insoluble in lipids.
Answer: Pretty sure its B
Explanation: When lithospheric plates move apart, it is called a divergent boundary. Mid-Ocean Ridges are found at divergent boundaries.
The other options don't make any sense as the answer.
Elbows and knees would be the answer
