Speciation has occurred.
What is Speciation?
The formation of new species from already existing populations is called Speciation. It is the evolutionary process of formation of new and distinct species. These species evolve by modifications of genes.
The newly formed species are reproductively isolated from the old species. They cannot reproduce with the previous species.
Speciation is of the following types:
Allopatric speciationParapatric speciationPeripatric SpeciationSympatric SpeciationGeographical isolation and hybridization are some factors that affect Speciation.
Therefore, when a population contains two separate groups that can no longer interbreed and produce fertile offspring, then Speciation has occurred

In one or two sentences explain the flow of energy in the food chain and why stored energy is an important part of it.
Energy in the ecosystem flow from one trophic level to other trophic level.
What is energy in ecosystem?
An ecosystem's feeding linkages are modeled by a food web. The materials and energy kept in a living thing's tissues are transferred to the organism that consumes it when it is eaten. This transfer is shown by the arrows in a food web.
Only 10% of the total energy available at a given trophic level is typically transmitted to the next level in most ecosystems. The remainder is either absorbed in little amounts or is needed to power various life processes.
Producers, or autotrophs, make their own organic molecules. Consumers, or heterotrophs, get organic molecules by eating other organisms. A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.
Therefore, Energy in the ecosystem flow from one trophic level to other trophic level.

One kind of plasmid in bacteria is called an r plasmid. What kinds of genes are typically present on such plasmids?.
The kinds of genes typically present on such plasmids are antibiotic-resistant genes and heavy metal resistance genes.
The discovery of the R plasmid confirms that bacteria not only have natural resistance genes but can acquire resistance to withstand survival pressures. This resistance is transmitted not only vertically, but also between species. Plasmids are extrachromosomal genetic elements found in many strains of bacteria.
They are small circular DNA molecules that replicate independently on the bacterial chromosome. Plasmids are mainly found in bacteria, Achaea, and other multicellular organisms. The R gene encodes a protein that recognizes the avirulence pathogen protein and initiates defense mechanisms that culminate in the hypersensitivity response. R-factors or resistance factors are plasmids that enable certain bacteria to acquire resistance to antibiotics.

You would predict that doubling the atmospheric [tex]CO_{2}[/tex] concentration would affect C3 plants as compared to C4 plants, C3 plants would experience faster growth rates.
Given that increase [tex]CO_{2}[/tex] causes a decrease in transpiration and an increase in [tex]CO_{2}[/tex] assimilation, it has been hypothesized that an increase [tex]CO_{2}[/tex] will increase the water use efficiency (WUE) of C3 species. Increasing the rate of photosynthesis is how C3 plants react to rising [tex]CO_{2}[/tex] levels.
Due to the higher concentration of [tex]CO_{2}[/tex] , the enzyme RuBisCo, higher atmospheric [tex]CO_{2}[/tex] levels would cause C3 plants to fix [tex]CO_{2}[/tex] more effectively and reduce photorespiration.

what enzyme catalyzes the site-specific recombination event to allow a copy of transposon copied to a new and another copy at the original site? what enzyme catalyzes the site-specific recombination event to allow a copy of transposon copied to a new and another copy at the original site? gyrase resolvase helicase transposase
Answer:
the answer is transposes.
Explanation:
Transposons, also called transposable elements, are mobile genetic elements that generally have only modest target site selectivity and can thus insert themselves into many different DNA sites. In transposition, a specific enzyme, usually encoded by the transposon and called a transposase, acts on a specific DNA sequence at each end of the transposon—first disconnecting it from the flanking DNA and then inserting it into a new target DNA site. There is no requirement for homology between the ends of the element and the insertion site.
Most transposons move only very rarely (once in 105 cell generations for many elements in bacteria), and for this reason it is often difficult to distinguish them from nonmobile parts of the chromosome. In most cases, it is not known what suddenly triggers their movement.
On the basis of their structure and transposition mechanisms, transposons can be grouped into three large classes (Table 5-3), each of which is discussed in detail in subsequent sections. Those in the first two of these classes use virtually identical DNA breakage and DNA joining reactions to translocate. However, for the DNA-only transposons, the mobile element exists as DNA throughout its life cycle: the translocating DNA segment is directly cut out of the donor DNA and joined to the target site by a transposase. In contrast, retroviral-like retrotransposons move by a less direct mechanism. An RNA polymerase first transcribes the DNA sequence of the mobile element into RNA. The enzyme reverse transcriptase then transcribes this RNA molecule back into DNA using the RNA as a template, and it is this DNA copy that is finally inserted into a new site in the genome. For historical reasons, the transposase-like enzyme that catalyzes this insertion reaction is called an integrase rather than a transposase. The third type of transposon in Table 5-3 also moves by making a DNA copy of an RNA molecule that is transcribed from it. However, the mechanism involved for these nonretroviral retrotransposons is distinct from that just described in that the RNA molecule is directly involved in the transposition reaction.

How many degrees of freedom are there in a chi-squared analysis of phenotype frequencies in the offspring from a dihybrid cross?.
3 degrees of freedom can be derived from the Chi-squared analysis of phenotype frequencies from a dihybrid cross.
The degrees of freedom in a Chi-squared table tells us how many numbers in the Chi grid are free/independent. It can be found out by the formula
d(f) = N - 1
Here
d(f) = Degrees of freedom
N = number of phenotype frequencies
Since there can be 4 possible phenotype frequencies in a dihybrid cross
d(f) = 4 - 1 = 3
Chi-square table actually serves as a source of reference that enlists the chi-square values which is used by statisticians to support their individual hypothesis. In a Chi-squared test the p value equal to or less than the significance level proves that there is ample evidence to prove that the distribution observed is not the same as distribution expected.
