The conductive tissues of the angiosperms are the xylem which drives the raw sap and the phloem which conducts the elaborate sap.The phloem, or liber, drives the elaborate sap, solution of organic substances rich in carbohydrates, from the leaves to the other organs.
The elaborate sap (which contains organic substances produces by photosynthesis) is produced in the leaves, where the majority of the chlorophyll subsist, so if the leave die off, the production of organic substances and the elaborate sap are reduced, so its transport by the phloem will be reduced, and this is how the phloem will be affected by the dying of the leaves.
The answer is B It must be testable.

Answer:
Alternative splicing explains how it works
Explanation:
Two different transcripts can be produced from one single gene according to the nature of exons and introns of every transcript, which means that a group of exons will form the future mRNA molecule. The nature of this phenomenon is based on the function and local that every transcript will act. These mRNA transcripts are the result of how the RNA polymerase and transcription factors interacts with DNA molecule and therefore selects the number and the size of the exons and introns of each mature mRNA transcript.
Answer: cellular metabolism
Explanation:
Cellular metabolism is chemical reactions that takes place in living organisms so that they will be able to maintain life. Cellular metabolism is made up of thousands of genes, metabolites and proteins.
Cellular metabolism is affected by the sympathetic nervous system but is not affected by the parasympathetic nervous system.
