Women also have a higher risk of developing certain complications during pregnancy, such as gestational diabetes, preeclampsia, premature detachment of the placenta (premature separation of the placenta and uterine wall) and placenta previa (when the placenta moves to the lower part of the uterus, covering the cervix partially or completely).
When looking at a Neuromuscular Junction (NMJ), we know that neurotransmitters (NT) are released from the presynaptic cell and they then bind to the receptors that are located on the postsynaptic cell - this causes the effect of the NT being released.
So we are told that NT are still being released, however they are not having an effect. This would mean that they are probably being blocked by something - in this case, it seems that the neurotoxin is the culprit in the blocking of these receptors.
Therefore, if the NT cannot bind to the receptors on the postsynaptic cell, they are not going to have any effect, no matter how much NT is being released.
So the answer in this case is: The neurotoxin is most likely C) Blocking the receptors on the postsynaptic cell.
The megasporangium in a pine cone is surrounded by an integument with a small opening called the micropyle.
Integuments in flowers are the maternal tissues or having a maternal beginning, as they originate from the ovular tissue or chalazal tissue (part of the lady reproductive gadget of a flower). A time period integument merely refers to the protecting layer. In terms of botany, an integument is a layer encircling the ovule.
A mature ovule consists of a meal tissue included by means of one or destiny seed coats, called integuments. A small establishing (the micropyle) within the integuments permits the pollen tube to enter and discharge its sperm nuclei into the embryo sac, a large oval cellular in which fertilization and improvement arise.

Answer: C
The substance that must come through the cell membrane for the cell to live is nutrients. Cells would die if they did not get nutrients. Nutrients are what keeps the cell running.
