Answer:Transcranial Magnetic Stimulation (TMS)
Explanation:
Transcranial magnetic stimulation also known as repetitive transcranial magnetic stimulation. TMS is a noninvasive procedure that uses magnetic fields to stimulate nerve cells in the brain to improve symptoms of depression. In TMS, brain cells are stimulated using a powerful magnetic field produced by a wire coil placed on a person's head that temporarily inactivates neural circuits. TMS devices operate completely outside of the body and affect central nervous system activity by applying powerful magnetic fields to specific areas of the brain that we know are involved in depression.
Nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.
Answer:
D hydrosphere
Explanation:
Soil erosion is the removal of the top soil layer. Soil erosion is controlled by precipitation (e.g. rainfall) and wind action. Continuous water flow on soil surface supports microorganisms to perform biogeochemical cycles. The phenonmenon is primarlity controlled governed at the iterface of geosphere (soil) and hydrosphere (water).
On the other hand, atmosphere (layers of gases), biosphere (living organisms), cryosphere (frozen water) are not directly related to soil erosion.

"They result in high non-response bias" is a disadvantage of online surveys.
<u>Option: A</u>
<u>Explanation:</u>
To several market analysts online surveys have become the default tool. It is fairly so. The ease of accessibility and the use of online surveys also in turn creates issues in itself. The advantages and disadvantages of online surveys are listed below:
<u>Advantages:</u>
- Accessible to most target audiences.
- Generally no cost-based geographic restrictions.
- Motivate flexible framework with countless question forms and formats.
<u>Disadvantages:</u>
- Poorly chosen networks of dissemination can contribute to skewed data, low success rates and a host of other possible problems.
- Difficulty targeting other groups of respondents, like those without internet access or samples of non-customers in niche sectors.
