Hershey and Chase used isotopes of sulphur and phosphorus. Please see the link.
the group1 elements
Metals in group one are chemically active as compared to the elements in group three and two. Elements like sodium, potassium, chlorine and fluorine are some of the chemically active elements.
Capacitors and inductors are considered passive elements, not active elements, because capacitors and inductors do not supply or amplify energy. An example of an active element is a battery, which supplies energy to a circuit.
No.
Fluorine
No. Au (gold) is one of the least active elements.
The easiest way to understand how viruses replicate is to study the life cycles of viruses called bacteriophages (bacteria eaters). Bacteriophages replicate by either a lytic cycle or a lysogenic cycle. The difference in these two cycles is that the cell dies at the end of the lytic cycle or the cell remains in the lysogenic cycle. The virus remains "hidden".
yes
Generally, the least reactive elements are the noble gases.
An active electronic element is one that can produce voltage gain or current gain.
Examples of active nonmetals include oxygen, fluorine, chlorine, and bromine. These elements readily form compounds and react with other elements to gain electrons.
The input motion to the active elements of a machine is typically generated by a power source such as an electric motor, hydraulic system, or pneumatic system. These power sources convert energy into mechanical motion that drives the active elements of the machine to perform their intended functions.
