A. The wave form moves forward, but the water particles do not advance appreciably.
Hope that helps! :D
Chemical factors: This is due to internal stimuli. Changes in the blood such as decrease in O2, increase in CO2 and decrease in PH cause impulse in the carotid artery which stimulates the respiratory centers in the medulla and cause breathing.
Mechanical factors: also called external stimuli. Compression of the fetal chest during delivery forces small amount of lung fluid out of the lungs. This increase in pressure in the chest draws air into the lungs.
Answer:
<em>Jansky Very Large Array </em>
Explanation:
It Is most powerful telescope on Earth and is located on the plains of San Agustin near Socorro, New Mexico, US. This telescope consist of 25 antennas whose collective ares is equal to a single 430 foot antenna. The angular resolution is equal to an antenna of 22 miles in diameter. It is also possible to adjust its arms to change its resolutions. There is receiver in each antenna that can operate from wavelength range of 4 mm to 7 metres. National Radio Astronomy Observatory is in charge of this telescope.
Answer: Botulinum toxin
Toxins are non-living
biological and chemical agents produced by living microorganisms from animals
and plants that can cause harm to humans, plants and animals. An example of
toxin is botulinum toxin produced by the bacterium Clostridium, which is a
neurotoxic protein that prevents the release of the neurotransmitter
acetylcholine from axon endings at the neuromuscular junction and causes
flaccid paralysis.
Moreover, toxin are more
closely related to chemical warfare agents that can only affect those who are
exposed to the agent and that they are not considered as transmissible disease.
They use C, thermal heat. This is because the vents use heat from the earth and it warms up the organisms that are very deep in the ocean. The reason they do not use sunlight is because they are so deep down in the ocean that sunlight will not reach them.
