It converts light energy which is abiotic, to glucose, which is consumed by organisms for energy. (It transfers to the appropriate type of energy for biotic organisms)

Answer:

The process of photosynthesis is considered as a bridge between the non living and living world because the substrate which is used in this process is non living and the plants that convert this into useful product is a living thing.

The carbohydrates that is produced by the plants body is used by the plants and animals which is also living thing.

The oxygen which is produced as a by-product is also used by the plant and animals and they are also living components of life.

Hence, it acts as a bridge between the living and non living components of life.

Which of the following statements is not true about mRNA?

musickatia [10]

Answer:

The correct answer is d. eukaryotes almost always produce polycistronic mRNA

Explanation:

In eukaryotes one transcription unit contains the information of only one gene which codes for only one protein or polypeptide therefore eukaryotic mRNA is called monocistronic mRNA.

In prokaryotes transription unit contains set of genes adjacent to each other which are transcribed together and codes for multiple proteins. So prokaryotic mRNA is called polycistronic mRNA.

Almost all messenger RNA present in eukaryotes are monocistronic mRNA because eukaryotes are more complex than prokaryotes and require modification at many stages which is easily possible with monocistronic mRNA.
