They should receive his or her vaccination at around 2 months of age!
Both oxygen helium and carbon dioxide are gasses. Also each of them is compressible<span>, which means that there is lots of free space between particles in oxygen helium and carbon dioxide. </span>
They are all elements that exist as gases by nadine.
siRNA prevent gene expression by binding to the product of transcription because <u>they bind to mRNA</u>
Explanation:
siRNA are short-sequence RNA strands, about 20 bp long, that bind to complementary regions on transcribed mRNA. This causes the formation of regions of dsRNA on the mRNA. This subsequently result in recruitment of enzymes such as Diver enzyme to cleave the mRNA and hence rendering it ineffective for translation into proteins. This is how siRNA negatively regulate genes, a process that has also been identified in research as a window to remedy genetic diseases.

Answer:
The correct answer is -
the independent variable - if fertilizer added or not,
the dependant variable - the height of the plant and
the standardized variable - 200ml water
Explanation:
In this study, the student wanted to see the effect of the fertilizer on the growth of the plant so the independent variable is the treatment of the fertilizer as manipulated or the independent variable is the factor which is affected or changed purposely during an experiment while other variables remain constant.
The dependent variable is the factor that is based or depends on the independent variable and measured to see the effect which is the height of the plants in this case.
The standardized or the control variable is the variable that remains constant throughout the experiment, 200 ml water treatment is the control variable in this experiment.
