Which atom is being researched as a possible ingredient of magnetic soap that can help clean up oil spills? carbon gold oxygen i
yaroslaw [1]

The correct answer is iron.  

The scientists from Britain discovered a soap with magnetic characteristics that could exhibit huge applications in the manner to fight against the damaging oil spills. In the mentioned soaps, the iron-abundant salts are supplemented to establish metallic centers inside the particles of the soap.  

After the solution is treated in a water source, a magnet was utilized to subjugate both the surface tension and gravity of the water, levitating the iron-rich scrubbing bubbles so that they can be withdrawn easily.

if the stimuli are delivered to the contracting muscles more frequently and ther is no time for relaxqtion
Mamont248 [21]

If the stimulus frequency is so high that the relaxation phase disappears completely, contractions become continuous in a process called complete tetanus.

What is tetanic contraction?

  • When the motor neuron that innervates a skeletal muscle generates action potentials at an extremely rapid rate, a persistent muscular contraction known as a tetanic contraction is induced.
  • A motor unit has experienced its motor neuron's maximum stimulation during this state, which lasts for a while. This happens when several impulses with a high enough frequency excite the motor unit of a muscle.
  • Every trigger results in a twitch. A slow enough stimulus delivery will cause the muscular tension to release between each succeeding twitch. High frequency stimulation will cause the twitches to overlap, which will cause tetanic contraction.

1.<br> Describe two advantages of genetic engineering.
Novay_Z [31]
One advantage of genetic engineering is the production of valuable proteins: recombinant DNA made possible the use of bacteria to produce proteins of medical importance such as genetically engineered human insulin which is of great importance.
Another advantage is the production of vaccines. Vaccines produced by genetic engineering offer an advantage that the microbial strains from which proteins are extracted do not contain complete viruses and thus there is no risk of accidental inoculation with live virus.

Which change resulted from the heating of the planets as they formed?
Gre4nikov [31]

It depends on the energy released by radioactive decay of uranium and other heavy long lived isotopes in the Earth's core and the internal heat of the Earth is produced by the original heat of formation that resulted from accretion and gravitational contraction.
