Which shows the pathway of the egg through the reproductive system? a. ovary → fallopian tube → vagina → uterus b. vagina → uterus → fallopian tube → ovary c. fallopian tube → ovary → uterus → vagina d. ovary → fallopian tube → uterus → vagina

D. ovary → fallopian tube → uterus → vagina

Explanation:

The egg/ovum develops in ovary. Ovary is a specialized organ in female reproductive system which is meant for the production and development of ovum. The ovum lies with in the follicle present inside ovary. The follicles mature from primordial follicle to primary follicle which then matures into secondary follicle, secondary follicle in turn matures into tertiary follicle and eventually it forms graafian follicle within the ovary. During the development of ovum, these follicles undergo several physiological changes. On the day of ovulation, graafian follicle ovulates its egg into the fallopian tube which is a part of female reproductive system. The fallopian tube has finger like projections named fimbriae which act as the receptor of the ovum. After that comes uterus which is also known as womb where embryo gets implanted. The uterus ends in vagina which is a part of birth canal.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
