Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression. Gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a cell functions.
Answer:
<em>The evolutionary process in work is the founder effect. Letter A.</em>
Explanation:
<em>The founder effect is a phenomena that happens when a small group of individuals becomes isolated from a larger population. Regardless of what the original population looks like, the new population resemble only the individuals that are founded the smaller one. The founder effect is that accompanies selecting a small group from a larger population. The separate population become genetically distinct from the original population.</em>
Answer: skin rashes or spread to the joints and blood. In Men: Discharge from the penis, swollen testicles. In Women: Vaginal discharge, pelvic pain, spotting.
The answer would be sedimentary rock because sedimentary is made up of small grains and also formed by deposition...
Answer
Operons are cluster of coordinated genes, including structural genes, an operator gene, and a regulatory gene.
Explanation:
In the The repressible operons, The transcription is usually on and repressor is in inactive form, So the specific genes are transcribed. While a regulatory molecule act as corepressor and binds to repressor protein to activate it. The repressor protein cause the inactivation of repressible operon (as the name indicate). E.g., Tryptophan Repress the trp operon.
A high level of product act as regulatory molecule (Corepressor) and turn off the operon, So anabolic pathways or synthesis of essential components are controlled by repressible operon.
In the Inducible operons, the transcription is usually off and repressor is in active form. So there is no transcription of genes. Specific Metabolite cause the activation of operon e.g lactose cause the induction of lac operon.
As a metabolite induces the operon, So they control the Metabolic pathways or breakdown of a neutrient.
