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.
Answer:
1) pollen grain (A), stigma (B), pollen tube (C), Ovary (D)
The pollen grain is a male reproductive part while ovary is the female reproductive part.
2) When a pollen grain lands on the stigma of a flower, a pollen tube begins to grow. It grows through the style until it reaches an ovule inside the ovary.
3) The pollen tube is a tube that transports the male gamete cells from the pollen grains to the ovule (female gamete) inside the ovary.
The nucleus of the pollen passes along the pollen tube and fuses with the nucleus of the ovule. This process is called fertilisation.
4) After the fertilisation, female parts of the flower develop into fruit and ovules become seeds.
Eating sharks will be of maximum risk.
Option D.
<h3><u>Explanation:</u></h3>
Biomagnification is a phenomenon where a toxin which is present in the environment is taken by smaller organisms and the concentration of toxins increase in concentration in higher tropic levels.
Suppose a toxin is present in sea water. It's taken by the small algae along with water which isn't metabolized by the algae, but stored in their body. Now these algae are consumed by small phytoplankton which consume a lot of algae, and the toxin present in their body, which again gets stored due to no metabolism. This even increases into smaller fishes, larger fishes and then into shark which has the maximum toxin concentration. So consumption of sharks will be of maximum health risk.
