True, there are equal numbers of protons and electrons in neutral atoms
Answer:
The phosphates provide energy for the bond between each nucleotide.
Explanation:
When each nucleotide is being bound, the two extra phosphates provide the energy needed for it to form the bind between each nucleotide that's being added to the RNA. Without this energy, the RNA wouldn't be able to form due to the lack of enough energy.
Answer:
Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O.
Explanation:
<span>If vinblastine prevents assembly of the spindle, then it interrupts cell division in Profase 1, when the assembly of the spindle begins. Paclitaxel prevents the depolymeritation of the spindle, so it will interrupt cell cycle in Anaphasis, when the dissasembly of spindle takes place.</span>
Answer:
Infectious dose refers to the minimum number or amount of pathogens required in order to produce a disease or its symptoms. In the given case, the bacterium is non-resistant and is treated with antibiotics.
The antibiotics help in neutralizing the infectious agents; however, full course should be done to eliminate the infectious agent completely out of the body.
If the course is left in between then, there are very high chances that some bacteria may survive. They might not produce disease or symptoms as they would be less than infectious dose.
However, with time, the survived bacteria gain more and more mutations during replication which can develop antibiotic resistance capability in them.
In addition, it is also possible that the survived bacteria can get R-plasmid (which has antibiotic resistant gene) from body's normal flora or from any other infectious agent present in the body by the process of transformation or conjugation.
The R-plasmid enables them to survive even in the presence of antibiotics due to which the treatment of the disease might become difficult.
