5. Which statement best describes the molecular structure of protein, along with one of the functions of proteins?
a. It is a straight chain hydrocarbon that can help fight disease
b. It is a complex, folded chain that helps regulate cell processes
C. It is a simple carbon, hydrogen and oxygen molecule that creates movement
d. It is a chain of nucleotides and forms muscle, bone, and ligaments

B

Explanation:

Proteins have 4 levels of folds, and help regulate cell processes.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.

the unequal cytoplasmic division that  results  in  one egg  and three polar bodies ensures that a fertilized  egg has  ample nutrients  forits journey  to  the uterus.
