<span>The correct answer is a. the overuse of fertilizer lead to reduced crop yields over time. This was unexpected because it is common for fertilizers to increase the yields and the quality of the product, but what happens over time is the opposite so it can be said that it's an unexpected consequence.</span>
Answer:
The disease that instructor list with a primary characteristic of erythrocytosis "Polycythemia Vera."
Explanation:
Polycythemia vera is a kind of plasma cancer. It reasons your bone marrow to kind too many red blood cells. These extra cells condense your blood, decelerating its flow, which may reason serious difficulties, such as blood clots. It is a stem cell complaint considered as a panhyperplastic, malignant, and neoplastic core ailment. Its most protruding feature is an raised absolute red blood cell mass since of unrestrained red blood cell manufacture.
Both mitosis and meiosis are a cell division process having various similarities and differences.
Similarities between the process of mitosis and meiosis include:
- Both the processes are cell division process.
- Both the processes occur in the nucleus of a cell.
- Both the processes result in the formation of daughter cells.
- The main phases are the same in both the processes
The differences between mitosis and meiosis include:
- As a result of mitosis, two daughter cells are formed. As a result of meiosis, four daughter cells are formed.
- The process of mitosis occurs in somatic cells whereas the process of meiosis occurs in reproductive cells.
- The daughter cells formed as a result of mitosis are the exact copies of parent cell. In the process of meiosis, genetic recombination occurs and hence the daughter cells are not exact copies of parent cells.

Answer:
Action Potential reaches the Axonal terminal
Vesicles filled with neurotransmitters move to the end of the axonal terminal
Neurotransmitters are released into the synaptic cleft
Neurotransmitters attach to the sodium channels on the dendrite.
Sodium channels open
Sodium moves into the Dendrite
Action potential travels through the dendrite
Explanation:
The process of transmission of action potential across a synapse ( a junction between two neurons) begins with the arrival of an action potential from the presynaptic neuron. The steps are given below:
Action Potential reaches the axonal terminal of the presynaptic neuron
Vesicles filled with neurotransmitters move to the end of the axonal terminal of the presynaptic neuron
Neurotransmitters are released into the synaptic cleft
Neurotransmitters attach to the sodium channels on the dendrite of the postsynaptic neuron
Sodium channels open
Sodium moves into the dendrite of the postsynaptic neuron.
Action potential travels through the dendrite towards an effector or another neuron.
