G Creating bonds to form biomolecules
H Producing sugars that assist with replication
J
Providing information to form proteins

Answers

Answer:J providing information to form proteins

Explanation:

The role of mRNA in expressing specialized structures is providing information to form protein. The correct option is J.

What is mRNA?

Messenger ribonucleic acid is a single-stranded RNA molecule that equates to a gene's nucleotide makeup and is read by a ribosome during the protein polymerization reaction.

The function of mRNA is to transport protein details from the nucleus of a cell to the cytoplasm.

Here the protein-making equipment likes to read the mRNA sequence as well as translates each three-base codon into the corresponding amino acid in a burgeoning protein chain.

Messenger RNAs are single-stranded molecules that move genetic information from the nucleus to the cytoplasm, in which proteins are sequenced.

Thus, the correct option is J.

Answers

Answer:

The correct answer is - (B) As with any living thing, a plant has an optimal temperature range at which it grows and performs best.

Explanation:

Like any other or most of the living organism, plants also required an optimal temperature range as they also required appropriate temperature for their growth and development and perform their functions at their best.

Optimum temperature range is a temperature range at which something performs its best similarly plants perform their cellular functions like photosynthesis, metabolism, reproduction, and many other functions that require a particular temperature range.

Answers

The lumbar and sacral nerves extend inferiorly beyond the end of the spinal cord, they form the Cauda Equina.

What is Cauda Equina?

The cauda equina, a group of nerves near the end of the spinal cord, is so named because it resembles a horse's tail. The top part of the lumbar (lower back) spine is where the spinal cord terminates.

The separate nerve roots that provide the legs and bladder with motor and sensory function continue along the spinal canal at the spinal cord's extremity. These nerve roots continue in the lumbar and sacral region as the cauda equina. These nerves carry signals to and from the pelvic organs and lower limbs.

Cauda equina syndrome (CES) occurs when there is dysfunction of multiple lumbar and sacral nerve roots of the cauda equina.
