Plasmids are used in genetic engineering to reproduce RECOMBINANT genetic material. When a plasmid is inserted a bacterium, the bacterum is encouraged to multiply, creating more copies of the recombinant DNA.

It is a circular piece of DNA that acts as a vector (a carrier of the gene). it attaches to the gene that is to be genetically engineered to form recombinant DNA (combined DNA of two different organisms). It allows the gene to be carried to a host cell to be replicated producing many identical genes. To cut open the plasmid requires an enzyme called restriction endonuclease and to stick the gene into the plasmid requires an enzyme called ligase

What does the age at diagnosis tell you about the mutation?

Vladimir [108]

The graph shows the ages of the women who have breast cancer, which range from ages 40 to 50. So it shows that this type of disease is most commonly diagnosed in women of these ages. Apparently, women are more prone to getting breast cancer the older they are. This is because as you get older, you lose some of your strength to fight these carcinomas so the risk of mutation grows higher as well.
Hope this helps!

Contractions per M

Andreyy89

To make Paramecium Contractile vacuole concentration graph useful the salt concentrations descriptions should replaced with actual values.

Thus, option "A" is correct.

What is Paramecium Contractile vacuole

"It is a sub-cellular structure (organelle) involved in osmoregulation."

<h3>What is a graph?</h3>

"A diagram (such as a series of one or more points, lines, line segments, curves, or areas) that represents the variation of a variable in comparison with that of one or more other variables."

<h3>What does the graph in the given question depict?</h3>

It shows that the Paramecium Contractile Vacuole concentration per minute decreases as salt concentration increases.

But the concentration of salt is not mention in quantity so its not clear what are the lowest and highest concentration affecting Paramecium Contractile Vacuole.

Hence, the Paramecium Contractile Vacuole concentration graph can be more useful if the actual values of salt concentration will be mentioned.

What is the value used to express the acidity or alkalinity of a solution?

melisa1 [442]

Answer:Acidity or alkalinity of a solution is measured by concentration of hydrogen ions (H+) versus hydroxyl ions (OH-) and is expressed as pH level, an exponential scale that ranges from 0 (very acidic) to 14 (very basic).
