yeah it's not A because that's for one cell multiplying itself to make another one pretty much, and it's not B because is not growing from another plant so yeah I would say its C
The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.
Answer:
The functions of the skeletal muscles are affected by the CNS via the two sets of neurons, that is, lower motor neuron and upper motor neurons. The PNS comprises sensory neurons and motor neurons. The lower motor neuron is monitored by the upper motor neuron.
Hyporeflexia occurs because of the dysfunction of the lower motor neuron or its lesion. The lower motor neurons refer to the neurons, which innervate the skeletal muscles directly. Destruction to the central nervous system leads to hyper reflexes and destruction to the peripheral nervous system results in hyporeflexia.
Nondisjunction results when chromosomes in gametes (egg and sperm cells) do not separate properly during meiosis (cell division of gametes in 2 stages), producing gametes which have more or less than the normal number (23) of chromosomes.
Nondisjunction occurs during anaphase of either Meiosis I or Meiosis II. Anaphase is the splitting and pulling of the chromosomes, lined up at the center of the cell, to the edges or poles of the cell. Shown in the figures below are examples of when nondisjunction occurs in Meiosis I (Anaphse I) and in Meiosis II (Anaphase II).
