6 0

Answer:

No atoms are created or destroyed in chemical reactions.

Explanation:

Matter cannot be created or destroyed. When two reactants contact each other, a chemical reaction occurs which breaks the bonds between atoms and rearranges them, forming new bonds which transform them into the product. The same amount of atoms exists before and after the reaction.

Organelles such as mitochondria and the endoplasmic reticulum have membranes that compartmentalize reactions and other metabolic
tino4ka555 [31]

Answer:

The correct answer is - they both have highly folded membranes.

Explanation:

Organelles such as the endoplasmic reticulum, Golgi apparatus, and mitochondria have highly folded double membranes. This highly folded membrane provides the increased surface area in the organelle.

As the inner membrane of these organelles is the site for many chemical reactions the highly folded or layered membranes get more space for such reactions to occur due to increased surface area.

nignag [31]

In prokaryotes the 5' UTR is 3-10 nucleotides.

In Eukaryotes the 5'UTR is 100 to many thousand nucleotides long.

Explanation:

Leader sequence or 5' UTR starts at transcription site and ends at the initiation codon just one nucleotide away from it.

It is present in mRNA.

These are GC rich and form secondary structure, helps in protein synthesis.

Shine Dalgarno sequence in prokaryotes is an example of 5'UTR.

It acts as an entry point of ribosome.
