Answer: Oviparity, expulsion of undeveloped eggs rather than live young. The eggs may have been fertilized before release, as in birds and some reptiles, or are to be fertilized externally, as in amphibians and many lower forms

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:
By analyzing the pelvis bone (sex determination) and the length of the diaphyseal bone and nonsynovial joints (age determination of non-adult skeletons and adult skeletons, respectively)
Explanation:
Bioarchaeologists are professionals that study human skeletons from archaeological sites. Bioarchaeologists can estimate the age and sex of human skeletons and thus determine the health and dynamics of past human populations. In regard to sex determination, the pelvis is a bone that can be used to estimate the sex of an individual with an accuracy higher than 95%. In regard to the age, characteristics associated with bone growth such as, for example, the length of the diaphyseal bone, can be good indicators to estimate the age of non-adult skeletons, while nonsynovial joints (i.e. joints without a synovial membrane) which are commonly called synarthroses or solid joints, can be used to estimate the age of adult skeletons.
