Occurrence: Spermatogenesis occurs inside the seminiferous tubules of a testis whereas oogenesis occurs inside the ovary. The product form in spermatogenesis is sperm which is flagellated i.e. motile and the product form in an Oogonium is ovum which is non-motile.
Question- Which molecule is correctly paired with its building blocks?
Answer- carbohydrate-monosaccharides
One of the reasons the plasma membrane can have<span> selective permeability</span><span> it's because it's composed by a bi-layer of phospholipids.
The interaction between them and other molecules will influence how these molecules will cross the membrane. If the molecule it's </span>hydrophobic it can easily cross, if it's polar molecules and ions( hydrophilic), they cannot cross easily.
Answer: An isotonic solution is a solution in which the amount of dissolved material is equal both inside and outside of the cell. Water still flows in both directions, but an equal amount enters and leaves the cell.

Answer:
b. pseudocoelom
Explanation:
A pseudocoelom is a false body cavity of some invertebrates which occupies the space localized between the mesoderm and the endoderm of the gut. This false cavity is found in nematodes.
Arthropods exhibit:
1- Bilateral symmetry because both opposite sides of the body are similar,
2- they are protostomes because the blastopore becomes the mouth during embryonic development,
3- they have true tissues because tissues are formed by groups of cells which share a common function, and finally,
4-arthropods are triploblastic because they are formed by three germ embryonic layers (endoderm, mesoderm and ectoderm).
