passage: Citric acid can be added to ice cream as an emulsifying agent to keep fats from separating, to caramel to prevent sucrose crystallization, or in recipes in place of fresh lemon juice. Citric acid is used with sodium bicarbonate in a wide range of effervescent formulae, both for ingestion (e.g., powders and tablets) and for personal care (e.g., bath salts, bath bombs, and cleaning of grease). Citric acid sold in a dry powdered form is commonly sold in markets and groceries as ``sour salt'', due to its physical resemblance to table salt. It has use in culinary applications, as an alternative to vinegar or lemon juice, where a pure acid is needed.
 question: can lemon juice be used as citric acid?
Yes

passage: Fold change is so-called as it is common to describe an increase of multiple X as an ``X-fold increase''. As such, several dictionaries, including the Oxford English Dictionary and Merriam-Webster Dictionary, as well as Collins's Dictionary of Mathematics, define ``-fold'' to mean ``times,'' as in ``2-fold'' = ``2 times'' = ``double.'' Likely because of this definition, many scientists use not only ``fold'' but also ``fold change'' to be synonymous with ``times'', as in ``3-fold larger'' = ``3 times larger.''. More ambiguous is fold decrease, where for instance a decrease of 50% between two measurements would generally be referred to a ``half-fold change'' rather than a ``2-fold decrease''.
 question: is 5 fold the same as 5 times?

Yes
