Answer:
a). At least one intron must be present in gene X.
b). At least two intron must be present in gene Y
c). It is impossible to determine whether there are any introns in gene Z.
Explanation:
Introns may be defined as the segments in the RNA molecule or the DNA molecule that does not code for proteins and they interrupts the sequences of each of the molecules.
In the context, we get :
a). In the gene X, at least one of the intron is present. Sometimes more than one introns may also be present. Due to slicing, we get one band less in the cDNA which is made from the mRNA.
b). In dene Y, at least one intron is present. Sometimes more than one introns are present inside the gene Y. In this case we get two bands less in the gene due to slicing.
c). In gene Z, it is not possible to determine the number of introns present in them. In genes X and Y, the Haelll enzyme is present in the intron. Therefore we get less of band after splicing the mRNA to cDNA.
Answer:
Your answer is C) latitude.
Answer:
zygote
Explanation:
or the mode of reproduction
Less reproductive isolation among populations that share similar habitats
<h3>What is Reproductive Isolation?</h3>
The reproductive isolation mechanisms are a set of evolutionary mechanisms, behavioral, and physiological processes that are essential for speciation.
They either prohibit individuals of other species from having children or guarantee that any children are infertile. When individuals or groups diverge in the time of various behaviors, such as foraging or mating, reproductive isolation can arise.
Toad species Bufo americanus and Bufo fowleri exhibit reproductive isolation due to changes in mating season. Members of these species can successfully cross in the lab, resulting in healthy, viable hybrids. Temporal isolation, ecological isolation, behavioral isolation, and mechanical isolation are the three modes.

The answer is nitrogen. It comprises
approximately 78% of the atmospheric air.
Nitrogen can be found in most life
processes including as a component of amino acids –amino group (NH3-). It is also involved
in the structure of nucleosides that are critical
in the formation of nucleotides and ATP.
