Large numbers of ribosomes are present in cells that specialize in producing molecules

Proteins.

Explanation:

Ribosomes are complex molecules present in all living cells, they are also called organelles. It serves as the site for protein synthesis. They can be gound freely in the cytoplasm or bound to certain organelles like the endoplasmic reticulum. They consist of two major structural components: the small ribosomal subunits, which read the mRNA, and the large subunits, which join amino acids to form a polypeptide chain.

There are 3 types of Ribosomes which are:

• Ribosomes link amino acids together in the order specified by messenger RNA (mRNA).

• Each unit also consist of ribosomal RNA (rRNA) molecules and a variety of ribosomal proteins.

• Transfer ribosomes (tRNA)

option c is the correct answer.

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 : )
