Indicate at which step of the replication-transcription-translati on process each type of rna first plays a role.

during which step of the replication-transcription-translati on process does each type of rna first play a role?

replication?
translation?
transcription/ rna processing?

The correct answer will be option- Translation.

Explanation:

There are main three types of RNA (mRNA, rRNA and tRNA) which are involved in the process of protein synthesis.  

During replication, none of the RNA is involved as DNA replication is associated with the formation of DNA from pre-existing DNA.

During transcription, Information coded on the DNA gets transcript into a molecule called mRNA which further acts as the coding molecule.

During Translation, the encoded mRNA gets translated into protein which requires all the three types of the RNA as mRNA acts as a messenger molecule, the site of translation takes place into ribosome which consists of rRNA and the tRNA which brings the specific amino acid.

Thus, translation is the correct answer.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.  

the answer is b.) hydrogen bonds between bases.
