Please answer correctly the following question related to the paragraph below. Which lake had more benthos? High lake had a lot of fresh and salt water mixing, therefore presented layers of stratified water.The water was poor in nutrients.Low lake had no such problems and it was a very abundant and prolific fishing spot. Hint: Water stratification is when water masses with different properties - salinity (halocline), oxygenation (chemocline), density (pycnocline), temperature (thermocline) - form layers that act as barriers to water mixing which could lead to anoxia or euxinia.[1] These layers are normally arranged according to density, with the least dense water masses sitting above the more dense layers. Water stratification also creates barriers to nutrient mixing between layers. This can affect the primary production in an area by limiting photosynthetic processes. When nutrients from the benthos cannot travel up into the photic zone, phytoplankton may be limited by nutrient availability. Lower primary production also leads to lower net productivity in waters.[2]

Answer: Low lake

Please answer correctly the following question related to the paragraph below. Which island had animals that reproduced in greater numbers? Dan studied two islands. Loon island had a very stable environment, and there weren't many diverse species of plants and animals. Wolf island displayed lots of evidence for natural selection, and had a large variety of species inhabiting it. Hint: New species develop naturally through the process of natural selection . Due to natural selection, organisms with traits that better enable them to adapt to their environment will tend to survive and reproduce in greater numbers. Natural selection causes beneficial heritable traits to become more common in a population and unfavorable heritable traits to become less common. For example, a giraffe's neck is beneficial because it allows the giraffe to reach leaves high in trees. Natural selection caused this beneficial trait to become more common than short necks.

Please answer correctly the following question related to the paragraph below. Which wavelengths would be shorter, case B or case C? Different wavelength electromagnetic radiations have different uses. John is a physicist. He needed to find appropriate wavelength electromagnetic radiations for his experiments. To that end, he selected three electromagnetic radiations, microwaves, infrared light, and visible light. He noted microwaves as case A, infrared as case B, and visible light as case C. Hint: Infrared (IR) light is electromagnetic radiation with a wavelength between 0.7 and 300 micrometers, which corresponds to a frequency range between 430 and 1 THz respectively. IR wavelengths are longer than that of visible light, but shorter than that of microwaves. Infrared may be detected at a distance from the radiating objects by "feel." Infrared sensing snakes can detect and focus infrared by use of a pinhole lens in their heads, called "pits". Bright sunlight provides an irradiance of just over 1 kilowatt per square meter at sea level. Of this energy, 53% is infrared radiation, 44% is visible light, and 3% is ultraviolet radiation.
