What causes blue whales to grow so large
Virty [35]

Answer:

Stronger upwelling created the right conditions for baleen whale prey, such as krill and forage fish, to become concentrated in dense patches along coastlines. Whales that fed on these prey resources could forage efficiently and predictably, allowing them to grow larger.

Describe the functions of the four photoreceptor proteins in human vision.
VLD [36.1K]

Answer:

In human vision, the cone visual opsins are grouped into four photoreceptor protein families LWS, SWS1, SWS2, RH2 .

  • SWS1: produce pigments sensitive to very short wavelengths, UV-violet, 360-450 nm.

  • SWS2: produce pigments sensitive to short wavelengths, blue, 450-495 nm

  • RH2: produce pigments sensitive to medium wavelengths, green, 495-560 nm

  • LWS: produce pigments sensitive to long wavelengths, yellow-red, 560-770nm.

Explanation:

Photoreceptor proteins are light-sensitive proteins that mediate light-induced signal transduction, thus they are involved in the sensing and response to light in a variety of organisms.

The photoreceptor proteins are classified based on the chemical structure of the chromophores involved, the light absorption and on the protein sequence.

This photoreceptor proteins are located at the cone photoreceptor cells and are responsible of photopic vision.

For scotopic vision, rhodopsin is responsible. Rhodopsins are the visual pigments (visual purple) of the rod photoreceptor cell in the retina. They are responsible of human vision in dim light, as it contains a sensory protein that converts light into an electric signal.

Relate bio capacity with ecological footprint
Lesechka [4]

Answer:

As the Ecological Footprint refers to continuous demand, and biocapacity refers to a continuous supply, both are correctly reported in global hectares. In the case of activity with a discrete start and end, such as the creation of an individual product, a different unit is required.
