Explanation:
Fertilization is a process of fusion of the male and female gametes of the organisms so as to produce zygote a precursor of new life. In living beings the fertilization is of two types named as external and internal fertilization.
In external fertilization the fusion of the gametes of opposite sex takes place outside the body of the organism. It is used by some aquatic organisms like fishes they lay their eggs in water which are fused by the male sperms also released in water. In external fertilization no direct sexual intercourse takes place.
In internal fertilization the fusion of the male and female gamete takes place inside the body of the female mate. This occurs due to direct sexual intercourse between the male and female partners.
The change in the environment affected how the organism would evolve to be so that it could survive. the term for that is survival of the fittest, and only the fittest would be able to survive the conditions of its surrounding environment. hope this answered your question. :)
Anammox (anaerobic ammonium oxidation), which is a reaction that oxidises ammonium to di-nitrogen gas using nitrite as the electron acceptor under anoxic conditions, was an important discovery in the nitrogen cycle.
The part of a riverbend that will experience the most erosion is the inside corner, this is because the water will be hitting it on two sides, the erosion will likely curve the inside corner more.
