Answer:
Postassium bisulphate - KHSO4 - can be used as an food preservative to protect the food from micro-organisms.
Answer: Transcription
In eukaryotic cells, transcription takes place in the nucleus. During transcription, DNA is used as a template to make a molecule of messenger RNA (mRNA). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs.

By taring a balance the process of weighing by difference is done automatically. When a balance is tared with an object on the balance pan, the weight of the object will be automatically subtracted from every reading until the balance is re-tared or zeroed.
The aluminium substances would retain the most heat for the longest period of time.
<h3>What is retaining heat?</h3>
Retaining of heat is the quantity of heat that a substance or medium can store over time or the amount of heat that a specific amount of that substance can hold in itself. Substances that store heat 'well' (for a long time) also require a long time to heat up.
Copper and aluminium have the highest thermal conductivity among the more common metals, whereas steel and bronze have the lowest. When determining the metal to utilise for a certain application, heat conductivity is a critical quality to consider.
In addition, potassium has the highest specific heat and the longest heat retention time. Polystyrene, a polymeric polymer, can retain heat for up to 11 hours. This implies it can hold heat for extended periods of time.
Hence the aluminium substances would retain the most heat for the longest period of time.
