Answer: The statement is false
Explanation:
Addition of concentrated sulfuric acid (H2SO4) to a beaker full of water (H2O) will release heat energy to the containing vessel due to the breakage of strong ionic bond present in the acid.
Thus, it is an evidence of a EXERGONIC REACTION (since energy is released spontaneously). So, the statement is false

Answer:
Nucleus
Explanation:
Expressing a gene basically means manufacturing its corresponding protein. This process has two major steps:
- In the transcription process, the information in DNA is transferred to a messenger RNA (mRNA) molecule. This first major step of gene expression and genetic splicing of exons occurs in nucleus environment of the cell.
- During translation, which is the second major step, the mRNA is "read" according to the genetic code, which relates the DNA sequence to the amino acid sequence in proteins. Within all cells, the translation occurs within a specialized compartment called the ribosome.
