Photorespiration or oxidative photosynthetic carbon cycle or C2 photosynthesis is a process in which enzyme RuBisCO oxygenates RuBP that leads to wastage of some energy formed during photosynthesis. This process involves three organelles chloroplast, peroxisomes and mitochondria.
Photorespiration occurs in dry and hot climatic plants when there is more oxygen in atmosphere than carbon dioxide. It is a light dependent process where glycolate is synthesized.
The plants have minimized its occurrence because it is a wasteful process. In photosynthesis carbon dioxide is used while in photorespiration carbon dioxide is releases. Thus, these processes work against each other so the plants minimize its occurrence.

B. Immune and circulatory

Vertebrates have backbones and invertebrates dont
There are four postulates of Darwin in which individual of species are not identical, traits are eased from one generation to the other and more offspring are born than that can survive. survivor of the competition for resources will reproduce only.
The four principle or postulates of Darwin are - variation , inheritance , selection and time. these all are considered the evolutionary component natural selection mechanism.
One is origin species by means of naturally selective mechanism, then preserve in the struggle of race of life.Darwin selection is mainly depends on the environment and heritable variations.All species of organisms which arise through natural selection of survive and reproduce.
