Before starting a cleaning task, what should be done is to sanitize first to make sure the cleaning product will work effectively (option A)
<h3>What are the stages of cleaning?</h3>
The stages of cleaning includes the following
1. Pre- Cleaning
The first stage of cleaning is to remove loose debris and substances from the contaminated surface you’re cleaning. You can do this by wiping with a disposable towel, sweeping, or rinsing. This process is also called sanitation. The aim is to remove as much substance as possible to prepare the area for the next stage of cleaning.
2. Main Cleaning
The second stage of cleaning is to loosen any substances, dirt, grease, and debris that you were unable to remove during the pre-clean stage. This involves using hot water and a detergent.
3. The Thirdstage of cleaning is to disinfect the surface, which will destroy bacteria and other microorganisms.
4. The fourth and final stage of cleaning is to dry the surface, and it’s recommended that you air dry where possible.
Therefore the prior process to cleaning is sanitizing the area for effective work.

Answer:
Root hairs are where most water absorption happens. They are long and so they can penetrate between soil particles, and prevent harmful bacterial organisms from entering the plant through the xylem vessels. They have a large surface area for absorption of water.
Explanation:
6 or 7
A child's 20 baby teeth, which often come in by age 3, usually fall out in the same order they came in. That means the lower center teeth (lower center incisors) are usually the first to go, around age 6 or 7. The top center pair is next.
The first stage is TRANSCRIPTION, it is a process that takes place in the nucleus or in the cytosol, the DNA acts as a template to transcript it's information forming a new mARN molecule which contains the codons that codes an specific amino acid.
This mARN molecule will exit the nucleus and will be translated in the ribosomas that can be found in the cytosol or the Endoplasmic Reticulum. during TRANSLATION the mARN will be decoded to produce a polypeptide chain, this happens when the ribosome induces the binding of a tRNA anticodon sequences that are complementary to the mRNA codons, this will tell the ribosome which amino acid is needed to form the polypeptide chain.
It's important to clarify that in Prokaryotic cells, both of these stages take place in the cytosol since it doesn't have organelles binded by membrane unlike the Eukaryotic cells where the Transcription happens in the nucleus and the translation happens in the cytosol or endoplasmic reticulum
