There would be less variability in the genes of the watermelon plants and is denoted as option A.
<h3>What is Variability?</h3>
This is defined as the difference between organisms which is caused by genetic or environmental factors.
Using the seeds from the largest, tastiest watermelons will reduce variability over time because these characteristics will become dominant.

Answer:
Option (D).
Explanation:
Dolly was the first sheep cloned in the year 1997. The sheep has been cloned from the adult somatic cells. The sheep was cloned by Keith Campbell, Ian Wilmut.
The adult's cell nucleus was fused with the enucleated sheep egg. The egg was then incubated in the surrogate female. The telomeres of Dolly sheep was found to be shorter than the normal individuals.
Thus, the correct answer is option (D).
If the inducer [allolactose] is present in the negative control then it will bind to the repressor decreasing its ability to bind to the operator due to which the transcription begins again and the operon is turned on.
Lac Operon is a set of three genes z, y & a which are regulated under the same promoter which regulates the amount of lactose production in the cell.
An inducer is a molecule that has the ability to induce or activate the operon. ex- in the case of the lac operon, allolactose acts as an inducer.
A repressor is a molecule that will repress or restricts the transcription of the genes of the operon, as a result, the operon will be switched off.
When the lac operon is under negative control, with no CAP [catabolite repressor protein] binding activity, the repressor remains active and thus binds to the operator region of the operon, as a result, no transcription takes place and the operon will be switched off.
But if the inducer will be present even in the negative control then the transcription takes place and the operon will be on.

The average carrying capacity of the range was estimated to be about 30,000 deer.
Answer:
Option D, They teach meteorologists how to record air and wind pressure.
Explanation:
A probe is a device which is used to explore space and collect information. It is an unpiloted device that consists of scientific equipment’s and instruments to study about the atmosphere , composition and other physical components of planets and others celestial bodies.
A probe transmits information from space through radio. A probe must be able to collect information even from extreme environmental conditions.
Hence, option D is correct.
