Scientists are able to manipulate dna within the cells of plants, animals, and other organisms to ensure that certain advantageous traits will appear and be passed on, or that certain harmful traits are eliminated. what is the term for this process?

The term for the process is called genetic engineering.

Explanation:

Genetic engineering is a process by which a gene containing the desired characteristics is integrated with a vector resulting in the formation of chimeric DNA molecule or recombinant DNA molecule.The recombinant DNA molecule is then incorporated inside a suitable host.

       The chimeric DNA then undergo gene expression inside the host resulting in the generation of desired protein.

      Genetic engineering can also be used to eliminate harmful traits by mutating the specific portion of the target gene that is responsible for the generation of harmful traits.

The term of the process is called genetic engineering.

Explanation:

The genetic engineering is the field of engineering; it is study of process of modifying the organisms of a genetic level. The example of genetic engineering is to inserting or modifying a gene into a organism. Its is also called as recombination DNA technology.

It involves the group of techniques used to cut the pieces or to join together using molecular scissors .the genetic engineering had the special potential to cure the genetic disease through gene therapy. It is widely used in field of agriculture, technology, scientific research.

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.

garbage disposal because lysosomes dispose of old cell parts like garbage disposals dispose of old food.
