A hydrophone array is made up of a number of hydrophones placed in known locations. These hydrophones maybe placed in a line on the seafloor, moored in a vertical line in the water column, or towed in a horizontal line behind a boat or ship, for example. Sound arriving at the array from a distant source, such as a submarine, will reach each hydrophone at slightly different times, depending on the direction from which the sound is coming. This time difference is known as the time-of-arrival-difference and can be turned into a direction. Using this information from all the hydrophones in the array, the direction from which the sound is coming can be pinpointed.
Even a simple array consisting of only two hydrophones can give the approximate direction from which a sound is coming. People do this all the time in air with a “receiving array” that consists of two ears. Sound arriving from a source, such as a person speaking, will reach each ear at slightly different times, depending on the direction from which the sound is coming, making it possible for the listener to tell the direction to the speaker.
Plants that use crassulacean acid metabolism (CAM)
photosynthesis repair CO2 at night, when their stomata are
open. CAM plants stock the CO2 typically in the method of malic
acid via carboxylation of phosphoenolpyruvate to oxaloacetate, which
is then concentrated to malate. Decarboxylation of malate during the day discharges
CO2 inside the leaves, therefore permitting carbon fixation to
3-phosphoglycerate by RuBisCO.
Explanation:
Abiotic processes in the carbon cycles : Management of the carbon cycle is the focus of global warming. Respiration, deforestation, burning of fossil fuels, and forest fires are processes that put CO2 up in the atmosphere. Organisms eat plants, which is comprised of carbohydrates come from CO2 in the atmosphere.
Answer:
Larger animals have a lower surface area to volume ratio. This means they need transport systems like our circulatory system and exchange surfaces like our lungs or fish gills. In single-celled organisms such as protists, and small multicellular organisms, essential molecules will move to where they're needed by diffusion.
