Answer:
b: many genes code for RNAs that function directly in the cell
Explanation:
<em>The central dogma</em> theory describes the basic framework for gene expression in living organisms. Genetic information from DNA is encoded or transcribed as RNA which then becomes translated as proteins.
The processes that take place for gene to be successfully expressed are;
- Replication
- Transcription
- Translation
<em>Replication</em> is a process whereby DNA makes a copy of itself to be distributed in daughter cells during cell division.
<em>Transcription</em> is the process whereby genetic information in DNA is encoded as RNAs. The RNAs are short-lived as they are quickly utilized in protein synthesis or <em>translation </em>process.
Hence, the RNAs do not function directly in the cells but mere intermediaries in the synthesis of proteins.
<em>The correct option is b.</em>
The appropriate answer for this one is C. Cancer cells divide uncontrollably and therefore the cell cycle would be continuously divide. To add, there is a term known as terminally differentiated cells. These cells that never enter the cell cycle again, meaning they stay in G0 and never divide. However, some cells can be triggered to depart G0 and re-enter G1, which permits them to divide again.

The atmospheric pressure drops so the partial pressure of O2 drops proportionately. The hemoglobin must circulate faster to deliver the same quantity of oxygen to working muscles' mitochondria for cellular respiration. This increased basal circulation rate places a greater demand for oxygen to support it, which triggers in increase in red blood cell population so there is more hemoglobin to deliver O2. With more RBCs the circulation rate once more slows to the old basal rate.
Answer:
This means that ¾ of the offspring have black fur, while the other ¼ are white. At this point students now have all the information needed to fill in the “predicted percentage” portion of the phenotype Punnett Square. The percentage for the black fur is 75% and white fur is 25%.
Explanation:
Diet and weight-loss companies create the illusion of isolation, as if everyone else has met the ideal beauty standard and that “you aren’t right now, but you can too!” Instead of focusing on the health of the customer, these companies promote their methods of weight-loss before any other. Use skepticism if an advertisement makes claims that seem “too good to be true”, are scientifically unsubstantiated, only provide one perspective/way of thinking, or appear to prioritize sales over health.
