The nervous system is one of the most important elements for our existence and survival, since it allows the management, organization and functioning of the rest of the corporal systems.
The synapse is a communication mechanism that occurs between two or more neurons in order to massively transmit a nerve impulse in order to coordinate a function in the organism.
The Chemical Synapse is the type of major synapse in our body. In these synapses the information is transmitted chemically, through the sending by the presynaptic neuron of different neurotransmitters that the postsynaptic neuron captures through different receptors, whose action generates an alteration in the form of excitatory or inhibitory postsynaptic potential that may end or not with the generation of an action potencial by the postsynaptic neuron. They are versatile synapses, since some neurons can inhibit the action of others depending on what is activated. There is no physical contact between both neurons.
Answer:
Answer is E. No males can be found.
Explanation:
The rotifers are invertebrate aquatic multicellular organisms. They are freshwater aquatic organisms with the possession of circles of strong cilia, which they use for locomotion, and thus the name wheel-bearer.
The Rotifers are grouped into three classes , which are Seisonidae, Monogononta and Bdelloidae.
The way of reproduction in these classes differ. The Seisonidae reproduce sexually, Monogononta reproduce sexually or asexually, and the Bdelloidae reproduce asexually.
The Bdelloidae reproduce asexually because they did not have males. They female produced the offspring from an unfertilized eggs . This process is known as pathenogenesis.
In this case, the Bdelloidae is the class that reproduce mainly by asexual reproduction because no male can be found.
Answer:
Most of the world's weather originates in the troposphere, a second scientist tells Carbon Brief, meaning that changes to seasonal temperatures could be affecting the likelihood of extreme weather events, such as flooding and drought.
