The answer is x-linked recessive. It is apparent that the color blindness affects the males hence it's caused by a sex-linked recessive gene. Males have XY homologous chromosomes. The X sister chromosome has more genes than the Y sister chromosome, hence most males are hemizygous for sex linked genes. This means that even recessive genes on the X chromosome are likely to be expressed in males.
This man is presenting with signs/symptoms of an inferior wall M.I. (myocardial infarction), a heart attack. He needs to be started on IV fluids with morphine, oxygen, nitroglycerin, and aspirin. However, it is imperative that before administering nitro/nitrates, he denies having taken any sexual meds for erectile dysfunction (e.g. Viagra) within the past 24 hours. That combined with nitrates can lead to a life-threatening irreversible crash of central blood pressure around the heart.

The postsynaptic potential is the membrane potential, which takes place in the neuron present post synapsis (after the chemical synapse). The presynaptic neuron releases neurotransmitter, which causes the firing in the postsynaptic neurons.
The firing of the post synaptic neuron depends on the excitation and inhibition inputs received from the presynaptic neuron. The firing is the resultant of the summation of excitatory and inhibitory potential. In case, the excitatory potential is greater than inhibitory potential, the post synaptic neuron would be excited. in case, inhibitory potential is greater than excitatory potential, then the post synaptic neuron would be inhibited.
Hence, the correct answer is option d.
Answer:
The answer is: letter C, The cell took in another ancient prokaryotic cell, which began living inside it.
Explanation:
"Endosymbiotic Theory" states that<em> certain eukaryotic organelles evolved when multiple cells merged together.</em> So, this created a <em>"symbiotic relationship"</em> among them. The organism that lives inside the other organism is called the "endosymbiont."
An example of this are the eukaryotic cells, which took in a <em>prokaryotic cell</em> (such as the ancient chloroplasts and mitochondrion). These ancient prokaryotes used to be free-living. They were often engulfed by another cell. However, in this theory, they are not killed; rather, the host cell helps it to thrive. <u>This caused the organelles to evolve together with the host cell.</u>
Thus, this explains the answer.
