Characteristics that are always present in a living organism include cells, metabolism, reproduction, homeostasis, and heredity sensitivity movement complexity

The correct answer for the fill in the blank is- Heredity.

Heredity can be defined as the transfer or characteristics or traits from one generation to the next generation that is from parents to their offsprings. It is accompanied through reproduction that can be via sexual or asexual mode. DNA ( deoxyribonucleic acid) is the genetic material of living organisms that is transferred from parents to their offsprings.

On the contrary, sensitivity, movement, and complexity are not always found in a living organism.

the answer is: trichonympha lives in the gut of termites and digests cellulose eaten by the termite.

this is an example of a symbiotic association of a protozoan with its mode of association.

"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."
