Answer:
Regulatory gene
Explanation:
Transcription is one of the major processes that occurs during gene expression. It is the transfer of the genetic instructions in DNA to mRNA. A strand of mRNA is made using complementary base pairs.
However, there is need for gene expression to be regulated.
Gene regulation refers to the mechanism that acts to induce or repress the expression of a gene. These include structural & chemical changes to the genetic material, binding of proteins to specific DNA elements to regulate transcription. These proteins that influences transcription by binding to specific nucleotide sequences (DNA segments/gene) are referred to as REGULATORY PROTEINS and those involved in regulating transcription of genes are called TRANSCRIPTION FACTORS.
Regulatory proteins controls the rate and manner of gene expression by binding to specific genes, thus, making it easy or hard for RNA polymerase (enzyme that attaches to DNA to synthesize mRNA molecule) to bind to the promoter of that gene.
Transcription factors (regulatory proteins) that promote gene transcription are called ACTIVATORS while those that decrease are called REPRESSORS.
Answer:
1. Obtain two identical containers and dry sand.
2. Shape equal amounts of sand into a "slope on the side of" each container.
3. Spray water on the sand in one container. The sprayed water represents "rainfall"
.
4. In the other container, "place ice cubes to melt on the sand. This represents snow or glaciers."
.
5. Observe and record the changes in the sand.
6. Analyze differences between the two containers.

The feature that you need to use in examining and make a
determination whether the skeletal remains in the pelvis is either male or
female is by analyzing its size and construction. It is because males have
larger pelvis bone and are robust elements compared to females who have smaller
and are light in terms of construction.
