Answer:
<h2><em><u>d) meiosis </u></em></h2>
Explanation:
The process of meiosis preserves genetic continuity for future offspring by ensuring that two sexually reproducing organisms produce offspring that have the same number of chromosomes as the parents.
It ensures that the offspring will be able to mate with other organisms of the same species.

146 gallons of water
<h2>Further explanation
</h2>
The human need for water (for drinking) is 8 glasses a day or about 2 liters. 1 gallon usually contains 19-20 liters. One house usually consists of 4 people <em>(father, mother, brother, sister).
</em>
If one person consumes 2 liters of water, then one house will consume about 8 liters a day.
Which will take up 2 gallons in 5 days.
1 Year = 365 days
365 days : 5 days <em>(2 gallons)</em> = 73 <em>(gallon water refill frequency)
</em>
73 x 2 = 146
So, within 1 year the level of gallon water consumption in an ordinary house consumes 146 gallons of water.
That is the calculation of the use of gallons for consumption, <em>not for bathing, washing, pooping, urinating, etc.

Answer:
The correct answer is option B, that is, promoter, operator, gene.
Explanation:
In a prokaryote, just in front of the operator, the promoter is located, and just in front of the structural genes, the operator is located. All these in combination give rise to an operon.
Any gene, which codes for an enzyme or a structural protein is termed as a structural gene, in the lac operon, a structural gene codes for three distinct kinds of enzymes. A short sequence of DNA is situated just in front of the structural gene, which is known as the operator. An operator functions as a switch for transcription, that is, it monitors whether the process of transcription will take place or not.
Just in front of an operator, a sequence of a promoter is present, and for the transcription and translation of all the structural genes, the RNA polymerase needs to combine first with the promoter. In case, if no transcription is to take place, then the operator allows the repressor to bind with it and prevent the attachment of RNA polymerase with the promoter. Hence, the correct sequence of a prokaryotic operon is a promoter, operator, and gene.
