Answer:
The corrects answer is option B.
Explanation:
The phloem is a structure present in the plant that helps in the translocation of the sugar, amino acids and other material from a source and the sink. This concentrated solution is known as sap. The translocation of the sap is bidirectional in the phloem. The site from the material move called source and the destination is known as the sink.
The driving force for the translocation of the materials is translocated by the pressure potential gradient between the source and the sink sites. It is a mode of active transport.
Thus, the correct answer is option B.
Answer:
because it cools you off when its too warm and overall gives a sense of calm

Answer:
Enzymes proofread the DNA after the DNA has been replicated and replace any mismatched nucleotides.
Explanation:
DNA replication occurs to make exact copy of original DNA. Transcription of genetic information to an intermediate mRNA occur after replication after which we have translation of genetic information into amino acids.
In the process of replicating DNA error can occur and then enzymes proofread the work for errors. Enymes DNA polymerase proofs read the replication,removes and replace the nucleotide base from where error occurs. It proof read after the DNA replication has occured.
This enzyme is also involve in DNA replication.
