Answer:
These spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). Interactions also occur among the spheres; for example, a change in the atmosphere can cause a change in the hydrosphere, and vice versa.

The center portion of each intervertebral disc is a filled with a gel-like elastic substance. Together with the annulus fibrosis, the nucleus pulposus transmits stress and weight from vertebra to vertebra.
In two species of birds, both of which form monogamous pair(one male and one female), In species 1, you find that the eggs in a pair's nest are in fact almost always the offspring of that pair. In species 2, you are surprised to find that many of the eggs in a nest were actually fathered by males of neighboring pairs. Apparently, mating outside of monogamous pairings is widespread in species 2. we would expect that female of species 2 would have sperm from multiple males in their reproductive tracts.
- This is because the species 2 are having many eggs.
- These eggs were formed due to fertilization with multiple male bird partners.
- As a result we can expect eggs with different genotypes.
Thus from the above points we can conclude that two species of birds, both of which form monogamous pairs, female of species 2 would have sperm from multiple males in their reproductive tracts

When charged particles from the sun strike atoms in Earth's atmosphere, they causeelectrons in the atoms to move to a higher-energy state. When the electrons drop back to a lower energy state, they release a photon: light. This process creates the beautiful aurora, or northern lights
