Answer:
The given blank can be filled with operator.
Explanation:
The proteins that assist in turning on or turning off the function of a specific gene by getting combined with certain sections of the DNA are known as transcription factors. The transcription factors that activate the transcription of a specific gene are known as activators, while that prevents transcription and is termed as repressors.
A repressor can be an RNA or a DNA binding protein, which prevents the articulation of genes by getting combined with the operator. A repressor, which binds with DNA prevents RNA polymerase from getting combined with the promoter, which further inhibits the transcription of the genes into mRNA.
Answer:
1.ans Phylogenetic Trees
Scientists use a tool called a phylogenetic tree to show the evolutionary pathways and connections among organisms. A phylogenetic tree is a diagram used to reflect evolutionary relationships among organisms or groups of organisms.
2.ans Binomial Nomenclature Rules
The entire two-part name must be written in italics (or underlined when handwritten). The genus name is always written first. The genus name must be capitalized. The specific epithet is never capitalized
3.ans Dichotomous Key
A dichotomous key is a tool created by scientists to help scientists and laypeople identify objects and organisms. Typically, a dichotomous key for identifying a particular type of object consists of a specific series of questions.
We've had the same amount of water on our planet since the beginning of time. Even though 70 percent of the globe is covered in water, less than 1 percent is accessible to us.
But now there is 6.7 billion people using that water. We're on track to be up to 8 billion people in 15 years. With our current population, there is already water stress.
