Answer:
Explanation:
Selection breeding is use to identify individual with good physical characteristics that can be used as parent in next generation. Brown, yellow, green grasshoppers are the distinct phenotypic characteristics of an individual hence selection will be individual base. Such that brown individual will be selected, green selected seperated and yellow will also selected. The organism that shows the best fits are often been selected depending on the objects of the selection
Answer:
When a nerve impulse reaches the end of an axon, the axon releases chemicals called neurotransmitters. Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron.
Explanation:
The binding allows the nerve impulse to travel through the receiving neuron.
Answer:
plasmid
Explanation:
plasmid
The human insulin gene is inserted into each plasmid. The plasmid acts as a vector - it is used to transfer DNA from one organism to another. Bacterial cells are made to take up the genetically modified plasmids.
The gaps (approximately 1 micrometer wide) formed between myelin sheath cells long the axons are called Nodes of Ranvier. Since fat serves as a good insulator, the myelin sheaths speed the rate of transmission of an electrical impulse along the axon.
