Consider this animal cell. which organelle is labeled i? cell membrane ribosome endoplasmic reticulum nucleus

The right answer is the nucleus.

The nucleus is a large structure surrounded by a double membrane, the nuclear envelope, which separates it from the cytoplasm. The membranes fuse in a few places, leaving openings called "nuclear pores", allowing the exchange of molecules between the nucleus and the cytoplasm.

The nuclear envelope is continuous with the granular endoplasmic reticulum, which is therefore bonded to the nucleus.

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 : )
