Answer:
Gametogenesis is the formation of gametes, in males it is referred as spermatogenesis and in females it is called oogenesis.
Explanation:
Differences between spermatogenesis and oogenesis:
1. Spermatogenesis is formation of sperms from spermatogonia and oogenesis is formation of ova from oogonium.
2. Location: Production of sperms occur in testis and production of ova occurs in ovaries.
3. In males, spermatogenesis begins at puberty and its a continuous process till death whereas in females, oogenesis begins at fetal stages, it halts and rest of the process occurs after puberty till menopause.
4. Primary spermatocyte undergoes meiosis-I to form two secondary spermatocytes, whereas primary oocyte undergoes to M-I to form a single secondary oocyte with a polar body.
5. Meiosis-II results in the formation of 4 spermatids or spermatozoa, in females however M-II results in only one ovum and second polar body formation.
6. Overall we can say that single spermatogonium forms 4 spermatids whereas single oogonium forms only 1 ovum.
7. Sperms are motile where as ovum in non-motile.
The skin and the liver are two organs that would be easy for stem cells to repair. What would be difficult to repair would be the apical meristem and the lateral.

Answer:
A slug would shrink and die if you were to sprinkle salt on in because it would cause water to leave the cells of the slug through the aquaporins in the cell membrane. This is because through osmosis water balances itself with the solute to reach equillibrium. When you pour salt on the slug you are making the outside a hypertonic solution that is going to draw out the water in the slug's cells.
