Answer:
What happens when compost worms interact with organic litter?
Compost worms interact with organic litter in order to get shade or hidden place against predator as t serves as shield for them
Explanation:
1) An action potential is propagated down the lower motor neuron
2) Calcium levels increase in the cytoplasm of the muscle cell
3) Acetylcholine binds its receptor and causes depolarization
4) Vesicles containing glutamate fuse with the nerve terminal
5) Contraction.
Answer:
4,1,3,2,5
Explanation: Glutamate is the neurotransmitter that excites the motor neurons and produces action potential in motor neurons. Then this action potential travels down towards the axonic terminal where it would cause release of acetylcholine. ACh then binds to postsynaptic membrane causing depolarization of sarcolemma. Calcium ions are released into the sarcoplasm resulting in muscle contraction.
White Blood Cells (WBC), produced by the stem cells found in the bone marrow, manufacture antibodies used to counter the effects of the antigens.
The White Blood Cells are known to provide immunity to the body against foreign bodies like bacteria, virus, proteins, etc. The lymphocyte cells, namely, the B-cells and T-cells are the two key cells that make antibodies for various antigens and kill or lyse the foreign body by recognising the antibiotic marker attach to them.
In physiology, a stimulus (plural stimuli) is a detectable change in the internal or external environment. The ability of an organism or organ to respond to external stimuli is called sensitivity. When a stimulus is applied to a sensory receptor, it normally elicits or influences a reflex via stimulus transduction.
Selective permeability, made possible in cells by the phospholipid bilayer that makes up the plasma membrane, is basically monitoring and regulating what can and can't enter the cell. It is carried out by a series of membrane proteins that act as channels to polar molecules, opening to allow them in and closing to prevent their entry. This is possible because the hydrophobic tails of the phospholipid molecules repel polar molecules and so prevent their entry unless through a channel.
