All living cells need nitrogen to make nuclei acids, proteins, and other cellular constituents. Plants absorb nitrogen and put them into amino acids and proteins.
The correct answer is: C. They transfer energy through a medium
There are different types of waves, depending on their medium: electromagnetic (energy is transferred through vibrations of electric and magnetic field), sound (energy is transferred through vibration of air particles), water (energy is transferred through the vibration of the water particles).
Longitudinal waves - particles vibrate parallel to the direction of wave propagation
Transverse wave -particles vibrate perpendicular to the direction of wave propagation.
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.
