An isotope has an atomic number of 8 and an atomic mass number of 18. How many neutrons does it have?
Paul [167]
The atomic number of an isotope is the number of protons it contains, whereas the mass number is the total mass of the nucleus, which is the combined number of protons and neutrons in the nucleus. To find the number of neutrons, you must therefore subtract the atomic number of the isotope from the mass number of the isotope. 
<span>In the above example, the atomic number is 8 and the mass number is 18. This isotope is known as O18. The number of neutrons in the isotope is: Mass number - Atomic number = Number of neutrons

Phage lambda lytic versus lysogenic phases are controlled by two proteins, Cro which leads to lysis and CII which leads to lysog
Juli2301 [7.4K]

Answer:

The maintainance of the lytic and the lysogenic cycle is done by the Cro and the lambda repressor proteins when the number of bacteria is higher than the number of viruses that is the mode of infectivity or MOI the virus under goes the lytic cycle. This is done by the cleaving of the proteins.

So high nutrient concentration in the gut promotes the growth of the E coli that forms a protease that cleaves the Cro protein and causes the activation of the lysis in the bacteria. So in the high nutrient concentration the bacteria is itself responsible for its lysis.

When a muscle cell demands energy to contract, what happens to ATP?
icang [17]
C. ATP (Adenosine Triphosphate) has three phosphate groups attached. Each one of the groups occupies an extremely high energy bond (free energy that can do work). In muscle contraction, that high-energy bond is broken and the energy is released for muscle contraction. So when the bond is broken, you end up with ADP (Adenosine Dipohosphate) - broken down.
