Answer:
Parenchyma cells are the abundant cells that make up ground tissues in plants.They are flat at point of contact.they have thin primary cell walls and have large vacuoles for storage of food.In leaves they are called mesophyll and are sites of photosynthesis.In other parts they are sites for respiration and protein synthesis.
Sclerenchyma cells are cells with rigid secondary cell walls.Their cell walls are hardened with lignin which is the main chemical component of wood.Mature sclerenchyma cells cannot elongate and most of them are dead.

Regretfully, you have not included in the question, the choices that would be our guide to arriving in the answer to this query. However, as a general knowledge, the acidity of a substance can be measured by its pH which is equal to,
pH = -log[H+]
which means that the increase in H+ ions will lead to the decrease in pH. A smaller pH value denotes that the substance is more acidic.

The answer to this question would be Rh incompatibility.
Rh or rhesus is a kind of antigen that can be found in human. Rh negative means that the mother doesn't have Rh antigen in her cell, so Rh antigen might be considered as "foreign body" and might activate white blood cell upon contact. If the father of the child has Rh positive gene, the child might become Rh positive and the child antigen can activate immune reaction and eliminated by mother white blood cells.
Rh incompatibility should be more severe in the second child since the mother white blood cells are more prepared than the first child(already sensitized).
