Answer:
myofibril bulbous end of axon and skeletal muscles fibres.
Explanation:o
It represents the chemical synapse of the axon bulbous ends of the motor neuron ( motor end plate) and the skeletal Muscle fibres.
The influx of calcium ions into the bulbous ends leads to the fusion and empty of the vesicles containing neurotransmitters into the synaptic cleft.
The Neurotransmitters binds to the receptors on the muscles membrane to allow the transmission of action potential ( PSIP or PSEP)across the synaptic gap to the muscles fibers to initiate their contraction or relaxation.
Diffusion is the type of transport that oxygen and carbon dioxide use to cross the cell membrane
Answer:
Chracteristics reffers to some organisms from kingdon protista;
Eukaryotic, Mostly Unicellualar, Aquatic, Posses mitochondaria, Parasitism, Asexual reproduction, Autotrophic, Heterotrophic.
Explanation:
Kingdom protista in one of five kingdoms and the term protista is derieved from "prortistos" meaning "the very first". The protists are considered as first eukaryotic life on earth.
Protistsa includes the Eukaryotic predominantly unicellular organisms. Protists are eukaryotic organisms and they cannot by classified as fungi, Plants or animals due to their chracteristics.
