Ametal cube has a mass of 18g and a volume of 2cm3. what is the density of the cube?

Density=9g/cm^3

Mass per unit volume  of a substance is known as density

density = mass/volume.

D=m/v

mass = 18g

volume= 2cm^3

d=  18/2

D= 9g/cm^3

"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."

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects
