how many amino acids are coded for the mRNA strand AUGCGAUACUGA

4

Explanation:

Amino acids are coded for by codons, which are triplets of nucleotides.

To work out how many amino acids are present, simply divide the cells into triplets.

AUG CGA UAC UGA

There are four triplet codons, so the sequence codes for four amino acids.

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 : )
