Ans.

Coral reefs are underwater ecosystems, made from growth and deposition of living or dead corals. Red algae play an important role in formation of coral reefs. The thread-like structures of red algae trap the sand sediments and particles of sands and cements, which provide mechanical support to the colony of corals and help them to grow.

When a pigment molecule in a light-harvesting complex absorbs a photon of light, what happens to its excited-state electron?.
MA_775_DIABLO [31]

When a pigment molecule in a light-harvesting complex absorbs a photon of light, While returning to its ground state, the electron transfers some of the energy from its excited state to an electron in a nearby pigment molecule.

  • It takes a photon of light energy some distance before it reaches a pigment molecule like chlorophyll.
  • An electron in the chlorophyll is "activated" by the photon. The energy imparted to the electron then moves from one pigment molecule to another until it reaches the reaction center, a pair of chlorophyll a molecules.
  • An electron in the reaction center is then excited by this energy, causing it to break loose and travel to the primary electron acceptor.
  • Therefore, it is said that the reaction center "donates" one electron to the main electron acceptor.

Two species of similar-looking insects have the same coloration, although one is poisonous and the other is not. This is likely
Vadim26 [7]

Answer:

The correct answer is option d, that is, mimicry.

Explanation:

Mimicry in evolutionary biology refers to an evolved similarity between the organism and another organism of other species. The phenomenon may take place between the individuals of a similar species or between the individuals of distinct species. The main objective of mimicry is to safeguard the species from predators, resulting in an antipredator adaptation.  

The evolution of mimicry takes place when the predator witnesses a similarity between the model and the mimic and as a consequence modifies its behavior in a manner, which offers a selective benefit to the mimic.
