Meiosis ll must take place because each of our new cells still has too much DNA.
(Hope this helps!!)
Herbivores. The eat directly from the producers. 10% of the producer's energy goes to herbivores, while only 10% of the 10% energy the herbivores had goes to carnivores.
Fragmentation is the breaking of the body into parts and then the organism develops all the parts of the body. The fragmentation is the type of reproduction in lower organisms. The fragments which are produced can develop into new organisms.
They are involved in a chemical digestion.
Chemical digestion involves breaking down the food into simpler nutrients that can be used by the cells. It begins in the mouth when food mixes with saliva which contains enzyme salivary amylase that breaks down carbohydrates. It also occurs in the stomach where HCl and pepsin forms chyme and small intestine especially in the duodenum.
All neurotransmitter receptors should be thought of as having two functions: First, to detect a particular neurotransmitter, and second, to do something<span> when they detect it. The receptor determines what the neurotransmitter's effect is. So it's not always right to call a neurotransmitter inhibitory or excitatory. Glutamate, for example, is among the most common neurotransmitters, and it's almost always excitatory... Except when it binds to a particular type of glutamate receptor, which is inhibitory. Done dopamine receptors are excitatory, some are inhibitory, and not all receptors have effects that fit neatly into those two categories. Sometimes a receptor will have an effect on something completely different... When the NMDA subtype of glutamate receptor is activated, for example, it can cause the postsynaptic cell to change what receptors it puts at that synapse (a cell can have different receptors at different synapses!).
