Both bacteria and amoeba are unicellular organisms. bacteria are considered to be prokaryotes, whereas amoebas are considered to be eukaryotes. how will you justify this reasoning? though both are unicellular, bacteria possess a well-defined nucleus without anucleolus. amoebas possesses a nucleus with a nucleolus, but no nuclear membrane. though both are unicellular, bacteria possess a well-defined nucleus and all essential cell organelles, whereas amoebas do not possess a nucleus or cell organelles, except ribosomes. though both are unicellular, bacteria doesn’t possess a nucleus or cell organelles, except ribosomes, whereas amoebas possess a well-defined nucleus and all essential cell organelles.

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."

for example, no new evidence will demonstrate that the earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the earth is not divided into solid plates that have moved over geological timescales .
