a) attraction between ions causes the dispersion forces.
Attraction between ions is a temporary attractive force which occurs when electrons in two consecutive adjacently placed atoms occupies positional confined areas that make the atoms acting like Temporary dipoles.
Dispersion forces or London Dispersion forces is the weakest force caused due to motion of electron.
On increasing the number of electrons the magnitude to Dispersion forces increases.
Dispersion forces also depends upon the atomic or the molecular weight of the given substance.
It is caused by an unequal and uneven distribution of the electrons inside an atom.
This causes a slight positive and slight negative charge to be formed inside an atom by establishing a temporary dipole. This temporary dipole induces a nearby atom by inducing another temporary dipole in the other one.

Answer:
A:The reproductive system produces hormones.
B:The reproductive system transports reproductive cells.
C:The reproductive system produces reproductive cells.
Explanation:
A:The reproductive system produces hormones. : The reproductive organs ovaries in females and testes in males produces hormones. The ovaries produce estrogen and progesterone and testes produce testosterone.
B:The reproductive system transports reproductive cells. : The ovaries in females transfers an egg into the fallopian tube and testes in males secrete sperms at the time of copulation the fertilization of egg and sperm leads to the development of zygote the precursor of new life.
C:The reproductive system produces reproductive cells.: The ovaries undergo oogenesis and in testes spermatogenesis takes place to develop egg and sperms respectively.
Explanation:
Answer:
At the plate boundary, there would be a divergent boundary where we can see a mid ocean ridge and a gap. We would be able to see the mantle because there would be a fissure from where magma will rise and solidify.
Explanation:
Under the South American plate and African plate, there are currents that cause a divergent boundary. They create this boundary since they pull the tectonic plates apart, causing a mid-ocean ridge with an opening that allows the rising of the magma that was underneath. Once that the magma is out, it solidifies, and the currents will try to create another ridge to repeat the process.
When the plates are apart, the mantle that is beneath is exposed, and we can see the magma.
