Answer:
C. Balancing a chemical equation simply means ensuring that the same numbers of atoms of the elements which are involved in the reaction (reactants) are represented in the result of the reaction (products). This demonstrates that matter is not created nor destroyed in a chemical reaction.
Explanation:
The products of a reaction contains a certain number of each atom constituting each product;
Matter cannot be created or destroyed so the reactants must contain the same number of each atom;
Balancing the equations means this will be the case and hence, this will demonstrate the number of each reactant atom/molecule necessary for the reaction to proceed
Called bioconversion although it can also be referred to as bio transformation
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.
<span>One process wherein diffusion is important is the concentration of salt within a cell. When the salt levels are too high within the cell, salt molecules are moving via diffusion to a region of lower concentration. Another process is the movement of carbon dioxide in plant cells, where CO2 moves from regions of high concentration to regions of low concentration.</span>
