1. an animal without a body cavity acoelomate

2. condition in which the left side of an organism's body is a mirror image of the right side bilateral symmetry

3. a series of chemical reactions that break down sugars and produce energy cellular respiration

4. an animal with a fluid-filled body cavity that lies within the mesoderm coelomate

5. an animal that has both male and female reproductive organs Hermaphrodite

6. an animal without a backbone invertebrate

7. free-floating aquatic animals with a structure similar to a jellyfish medusae

8. the transformation of a larva to an adult; occurs only in animals having great differences in form between the larva and adult metamorphosis

Explanation:

Body cavity is a fluid-filled space inside a multicellular organism  with the protective role. The coelom is the main body cavity, found in allmost all animals. Those that don't have coelom are called acoelomata. An example are Platyhelminthes.

Symmetry refers to the proportion of an animal: its reflection, rotation or scaling. The body symmetry of animals might be radial, bilateral, spherical or asymmetric.

Two major group of animals are Vertebrate and Invertebrate, with or without with backbone.

Hermaphrodite organisms are those that contain both, male and female reproductive organs, characteristic for invertebrates.

answer; i believe the answer is hydraulic action;

"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."
