Answer:
750 to 1,250 cubic centimeters.
Explanation:
<em>Homo erectus </em>is also known as the upright man. There species were present in the Pleistocene era. Their first fossil was dated back at 1.8 million years ago.
The brain capacity of<em> Homo erectus </em>was found to be between the 750 and less than 1,250 cubic centimeters. Their species had been derived into<em> Homo heidelbergensis.</em>
Thus, the correct answer is option (D).
Action potential Axsen terminal dendrite neurotransmitter receptors synapse vesicles and calcium ions are the answer
Answer:
Arterial blood gas (ABG) results from a 68-year-old woman with difficulty breathing show:
- Oxygenation (PaO₂): hypoxemia
- pH: acidosis
- PaCO₂: Hypercapnia
- HCO₃⁻: normal
whose interpretation is: <u>respiratory acidosis</u>.
Hypercapnia can produce symptoms such as confusion, drowsiness or lethargy, headache, nausea and vomiting and, in severe states, can cause severe unconsciousness and coma.
Explanation:
Respiratory acidosis is due to a failure in the breathing process that produces <u>hypoventilation</u>, decreasing the partial pressure of oxygen (PaO₂) —hypoxemia— and increasing the partial pressure of CO₂ (PaCO₂), called hypercapnia.
- <u><em>Acidosis</em></u><em> is the result of the accumulation of CO₂ in the body, which is reflected as a decrease in </em><em>pH</em><em> below 7.35, with no change in bicarbonate content.</em>
- <u><em>Hypoxemia</em></u><em> is the decrease of PaO₂ below 60 mmHg.</em>
- <u><em>Hypercapnia</em></u><em> is the increase of PaCO₂ in ABG above 45 mmHg.</em>
- <em>Normal </em><em>bicarbonate</em><em> </em><em>(HCO₃⁻) </em><em>values range from 22 to 28 mEq/L in ABG. This compound can be altered in metabolic acidosis.</em>
<u>Hypercapnia mainly affects the nervous system</u>, producing symptoms that alter the state of consciousness of the affected, also producing headache and even nausea and vomiting.
Answer: d. all of the above.
