Answer:

Exothermic reaction

Explanation:

An endothermic reaction absorbs energy, while an exothermic reaction releases energy. In this scenario, the balloon explodes with a loud bang and creates a fireball which would be considered releasing energy. Therefore, the reaction taking place is exothermic.

iren [92.7K]

Answer:

Increase in transcription

Explanation:

Transcription is the process of forming RNA from DNA. It can be controlled by many factors like a repressor. Repressor can bind to the operator region of the promoter and hinder the movement of RNA Polymerase enzyme, halting the process.

Here, it is given that the repressor needs to first bind to an effector molecule X. Once it binds to X, it is activated and then it can bind to operator of gene A to inhibit its transcription. If the X binding domain on repressor is mutated it wont be able to bind to X. Thus it wont get activated and wont be able to attach to operator region to inhibit transcription. Hence, transcription process will keep going on uncontrolled.

Which statement best describes the relationship between proteins and nucleic acids?
Iteru [2.4K]
Although the options are not provided, the statement best describing the relationship is nucleic acids provide blueprints for the construction of proteins.
Messenger RNA molecules (mRNA) take instructions from DNA molecules and take the code out of the nucleus. There, ribosomes work with the RNA molecules to produce a chain of amino acids, which in turn links and folds in a specific manner to form a protein molecule.

Which cellular process takes place in the ribosomes that are bound to the endoplasmic reticulum
yaroslaw [1]
The cellular process is protein synthesis. <span>After a strand of DNA is transcribed into RNA, it is sent to the ribosomes to undergo translation, where it reads the code on RNA and makes a corresponding amino acid based on the RNAs base pairs. A chain of amino acids will make up a protein.</span>
