Answer:
Both the food chain and food web represent flow of food and energy through various organisms (including plants) and point from the producers to the consumers. Both the food web and food chain include a number of organisms including both producers and consumers (as well as decomposers).
In their simplest form, food webs are made of food chains. Food chains show a direct transfer of energy between organisms. A chain might involve a mouse eating some seeds on the forest floor.
for example A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.
The correct order is:
- Action potential arrives at the axon terminal.
- Calcium ions enter the axon terminal.
- Synaptic vesicles fuse to membrane of axon terminal.
- Acetylcholine is released into the synaptic cleft.
- Acetylcholine binds to its receptors on the junctional folds.
- Junctional folds become depolarized.
- Action potential is initiated on the sarcolemma.
Action potential travels through the membrane of the presynaptic cell causing the channels permeable to calcium ions to open. Ca2+ flow through the presynaptic membrane and increase the Ca concentration in the cell which will activate proteins attached to vesicles that contain a neurotransmitter (e.g. acetylcholine). Vesicles fuse with the membrane of the presynaptic cell, thereby release their contents into the synaptic cleft-space between the membranes of the pre- and postsynaptic cells. Neurotransmitter binds to its receptors on the postsynaptic membrane and its binding causes depolarization of the target cell (muscle cell).
Answer:
Volume
Explanation:
In chemistry, the CONCENTRATION of a solution is the amount of a substance present within a volume of another substance. In other words, the concentration refers to the amount of a solute dissolved in a particular volume of a solvent to make a solution.
Concentration can be expressed in mass per volume i.e. g/cm³ or mol per volume i.e. mol/L or mol/dm³ etc. The amount of a substance is measured in Mass or mole, while the volume of a substance in Litres (L).
