Answer:
If the ovary does not enter the fallopian tube, it falls into the abdominal cavity and cannot be fertilized unless it finds it's way back to the uterus. Ectopic or tubular pregnancy would cause the fallopian tube to swell and eventually rupture.
Explanation:
When ovaries are released by the oviduct, it enters the fallopian tube, fertilizes and moves to the uterus where it is implanted. But if the ovum does not enter the fallopian tube, which could be as a result of an abnormality or the fallopian tube removed to prevent pregnancy or for medical reasons, then the ovum enters the abdominal cavity.
Pregnancy is still possible in this case if the ovum finds its way back to the uterus or IVF is been administered to the patient to induce pregnancy.
Ectopic or tubular pregnancy occurs when a fertilized egg is implanted in the fallopian tube. This is sometimes the case in the early weeks of pregnancy but eventually moves to the uterus. In severe cases, it would remain in the tube which in turn would make the tube swell and rupture.
Darwin’s theory became accepted because it had more evidence that supported it. Lamarck’s theory suggest that all organisms become more complicated over time, and therefore doesn’t account for simple organisms, such as single-cell organisms. We also know through observation that characteristics inherited during an individual’s lifetime do not get passed onto their offspring; for example, if someone pierces their ear, it doesn’t mean that their children will be born with pierced ears. Darwin’s theory became even stronger when, many years after his death, the study of genetics emerged. Genetics ultimately showed that all inherited traits were passed on through genes, which are unaffected by outside world, as Lamarck would predict, and are instead naturally varied, as Darwin predicted. Though Darwin didn’t know what genes were, he could see their effect on natural selection.

The inter-tidal zone refers to an area that is under water during a high tide and exposed to the air at low tides. Organisms living in the inter-tidal zone must be adapted to living in an extreme environment. They must be able to survive for sometime without water and in water that can be high or low in salinity. The nearshore zone is always under water and is the area where waves can break in their approach to the shore. Organisms here are adapted to living completely submerged in water.
