Among the ones listed above, the statement that best describes the way that the periodic table is arranged is "<span>The nonmetals are grouped together, which the exception of hydrogen.</span>" It can be seen that all of the nonmetals are placed on the far right of the periodic table except for hydrogen. They do not belong in a single column and are separated from the metals by the metalloids. Moreover, the elements are placed in the periodic table in increasing atomic number.
For the second wig its decreasing
Answer:
Parapatric speciation
Explanation:
There are different types of speciation. Parapatric speciation consists of new species evolving from a continuous distribution. That is, there is no physical barrier that might impede the gene flow, in fact, it might continue during the speciation process.
There is an environmental gradient that determines different phenotypes for different environmental conditions. One phenotype is more adapted to one of the distribution extremes than the other phenotype. In the exposed case, the environmental gradient is given by the differences in pH.
In the border between the environmental extremes, there is the primary hybrid zone, where both phenotypic forms might meet and hybridize.
Answer:
One controversy that has resulted from the Human Genome Project is the ethics of genetic engineering and whether it should be used to create so-called "designer babies." Proponents of genetic engineering argue that it has the potential to eliminate genetic disorders and diseases, and that it could improve the overall health and well-being of future generations. For example, parents could use genetic engineering to ensure that their children have a lower risk of developing conditions like diabetes or heart disease.
On the other hand, opponents of genetic engineering argue that it could lead to a number of social and ethical problems. For instance, some people worry that genetic engineering could be used to create a society of genetically superior individuals, leading to inequality and discrimination. Additionally, opponents argue that we do not yet fully understand the potential risks and long-term effects of genetic engineering, and that we should therefore proceed with caution. They also raise concerns about the potential misuse of genetic engineering, such as using it to create individuals with enhanced physical or intellectual abilities for military or other nefarious purposes.
In conclusion, while genetic engineering has the potential to bring many benefits, there are also valid concerns about its potential consequences. It is important for society to carefully consider these issues and to proceed with caution.
Explanation:
They first 'cut out' genes using precise biological 'scissors' – restriction enzymes – and paste them into DNA from another organism like a bacterium or yeast where it is copied many thousands or millions of times. Molecular model of a restriction enzyme bound to DNA.
