The heart is divided into four chambers. The two upper chambers are called atria (Singular : atrium) and the two lower chambers are called the ventricles. The partition between the chambers helps to avoid mixing up of blood rich in oxygen with the blood rich in carbon dioxide.
The right side of the heart is completely separated from the left side with the help of a partition called septum so that the two types of blood do not mix. The heart has a number of valves that allow the blood to flow in one direction only.

The flower uses nectar to attract pollinating animals and uses it as a reward for carrying out pollination. Nectar is also utilized by honeybees to produce honey. Bees can sense the electrical charge of the flower that possesses nectar. If a flower's nectar is already harvested, the positive electrical charge of the flower increases and the bees avoid such flowers. They can also detect nectar by the reflection of UV rays and by the tone of light that the flower emits to attract pollinators.

d) FSH and LH. (Prior to ovulation, the egg cell is developed from oogonial cell through different stages of follicular development. The FSH or follicle stimulating hormone is what helps in the formation and ensures the uninterrupted development of these ovarian follicles. As the secondary oocyte in the Graafian follicle proceeds towards ovulation, LH or Luteinizing hoone is released which hastens the rupture of the Graafian follicle to release the ovum out into the fimbriae and leads to the formation of Corpus luteum, the formation of which was the prime requirement of the LH.)

When the male individual approaches puberty, the hypothalamus directs the production and release of the Luteinizing hormone in their bodies which through the bloodstream are sent into testes. These cells interact with Leydig cells and aid the production of androgens.)
