Answer: The solid is a mixture
Explanation:
Here's the complete question:
If a solid contains some particles that melt at 50°C and other particles that melt at 110°C, what must be true about the solid?
A. The solid is an element.
B. The solid is a mixture.
C. The solid is a pure substance.
D. The solid has three boiling points.
It should be noted that an element consist of an atom but in this scenario, there are different particles that also have different melting points. Therefore, it's not an element, but rather a mixture.
Also, the solid in this case is not a pure substance and doesn't have three boiling points.
Therefore, the correct option is B.
Answer:
Dendrites
Explanation:
Dendrites or dendrons are the branching of protoplasmic extensions of a nerve cell. As the neurons are arranged in head to tail manner, these dendrites lie close to the axon terminals of the other neuron and thus they receive signals from the other neurons and then pass the received signal to the main body of the neuron which is also called Soma. The electrical signals are passed from one neuron to the other neurons via the synapses which are located at various points on the dendrites.
