Answer:
In meiosis, chromosome number in daughter cells is reduced by half while in mitosis the chromosome number doesn't change.
Explanation:
In mitosis there is a single cell division, while in meiosis there are 2 cell divisions.
In both cases the process start with the replication of DNA, so each chromosome has two sister chromatids.
- In mitosis, the sister chromatids separate, resulting in two daughter cells identical to the original cell, before the DNA replicated.
- In meiosis, homologous chromosomes separate during the first cell division, giving two daughter cells with half the chromosome number of the original cell, but each of them still has two chromatids. During the second cell division the chromatids separate, resulting in a total of four daughter cells, each with half the chromosomes than the original one.
Answer:
A neuron receives stimuli consisting of the response of thousands of neurons. Synapse is the signals entering the neuron via junctions called. The role of the synapses are to modulate the signal strength and determine the input signal is either excitatory, promoting the neuron to fire, or inhibitory, tending to prevent the neuron from firing.
At the axon hillock the neuron integrates the inputs and if this total is excitatory then the neuron fires. Although this brief description leaves out much of the complexity, it is still remarkable that out of this web of electrochemical firing units, emerges our very conscious.
The organelle malfunctioning in this case is lysosome. They have powerful enzymes and acids to digest and recycle cell material so they remove waste from the cell.
Carbohydrase or amylase enzymes break down starch into sugar.
The appropriate nursing intervention would be to initiate a consultation with the hospital chaplain and the patient. Cultural competence in healthcare should be applied, in order for the patient to receive care services that meet his religious, cultural and spiritual needs. In this example, the hospital chaplain could provide spiritual guidance and counselling.
