Graduated cylinders because you can put liquid in it
The correct answer is triglycerides, this is the monomer that is made up
of gylcerol and one other molecule. The other molecule within the
monomer will depend on the use of the tryglycerde - for example, in
adipose tissue, tryglycerides are composed of one molecule of glycerol
and three moles of fatty acid.
Snapper overfishing
Explanation:
Coral reefs are becoming highly vulnerable due to increased anthropological exploitation of the ocean reserves. Overfishing, usage of non-selective fishing gears, fishing the spawning areas, fishing using nets etc all affect the coral reefs and the marine ecosystem. The coral reefs and the fish population are interdependent and overfishing greatly impacts both the factors.
Overfishing is the main reason for damage and decline in coral reefs. The snappers are carnivores and survive on eating other fishes which can be herbivores or omnivores. Snappers remain at the top of the food pyramid of the marine ecosystem. A reduction at the top level of the food pyramid will automatically disturb the lower level population and the energy flow between each cycle. A reduction in carnivores leads to increase in herbivores which in turn deplete the coral reefs. Coral reef is a habitat for many fish populations, and a reduction in the habitat will again reduce the overall population of fishes. A decrease in predator population will increase prey population.
Troposphere
The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). This part of the atmosphere is the most dense. Almost all weather is in this region.
Stratosphere
The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high. The ozone layer, which absorbs and scatters the solar ultraviolet radiation, is in this layer.
Mesosphere
The mesosphere starts just above the stratosphere and extends to 85 kilometers (53 miles) high. Meteors burn up in this layer
Thermosphere
The thermosphere starts just above the mesosphere and extends to 600 kilometers (372 miles) high. Aurora and satellites occur in this layer.
Ionosphere
The ionosphere is an abundant layer of electrons and ionized atoms and molecules that stretches from about 48 kilometers (30 miles) above the surface to the edge of space at about 965 km (600 mi), overlapping into the mesosphere and thermosphere. This dynamic region grows and shrinks based on solar conditions and divides further into the sub-regions: D, E and F; based on what wavelength of solar radiation is absorbed. The ionosphere is a critical link in the chain of Sun-Earth interactions. This region is what makes radio communications possible.
Exosphere
This is the upper limit of our atmosphere. It extends from the top of the thermosphere up to 10,000 km (6,200 mi).
