The study of an organism that lived 10 million years ago would most likely fall under which two branches of natural science?

The study of the organisms that existed in the past, about millions of years back is known as paleontology. And this ancient organisms are called fossils.

The two branches of natural science that includes paleontology are earth science as well as biology.

paleontology has a great significance and this subject helps us in understanding about the various conditions, i.e how organisms in the past have lived, their behavior pattern, their food habitat, the climate and weather condition in the past and many more things.

well we can't tell you because we cant see the time give a screen shot or something.

"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."
