The skeletal system of animals provides structure and support. which cell part provides a similar function in the cell?

a. proteins

b. cytoskeleton

c. nucleus

cytoskeleton

Explanation:

Eukaryotic cells contain proteins called the microfilaments (actin),microtubules( tubulin) and the intermediate filaments that are collectively coined as the cytoskeleton. The mechanical strength of the cell that is provided is due to protein scaffolding in the cytoskeleton. In addition, protein scaffolding can also determine the shape of the cell. This therefore shows that cytoskeleton provide both structure and support to cells.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )

a and c are the answeres
