Answer:
Increasing the number of women receiving prenatal care
Explanation:
Prenatal care is the medical follow-up that every pregnant woman should have in order to maintain the integrity of the mother and baby's health conditions. Throughout pregnancy, laboratory tests are performed to identify and treat diseases that can harm the health of the mother or child. For this reason, prenatal care is a great strategy for decreasing child mortality. Thus we can conclude that a program designed to lower the child mortality rate in the United States would probably have the greatest impact if it focused on increasing the number of prenatal women.
Most veins carry deoxygenated blood from the body back to the heart.
Answer:
The correct answer is c. partial pressure of carbon dioxide (PCO2) in arterial blood.
Explanation:
Ventilation is a term generally used to designate the movement of air in and out of the lungs, that is, alveolar ventilation is the volume of air that reaches the alveoli in one minute and participates in gas exchange. Carbon dioxide partial pressure (PCO2) consists of analyzing the amount of dissolved carbon dioxide in the blood, just like with pO2. Normal results range from 35mmHg to 45mmHg. If the level is low it may indicate respiratory alkalosis; if the level is high it may indicate respiratory acidosis. It can only be analyzed in arterial blood.
C. heart disease.....
Other symptoms may include
. sudden weakness
. paralysis (not being able to move) or numbness in body
. confusion
. trouble speaking or understanding speech
. trouble seeing in one or both eyes
. problems breathing
. Dizziness, trouble walking, loss of balance or coordination, and unexplained falls

<u>This question is off-topic, but I'm answering it assuming you meant to categorize as maths.</u>
Answer:
or 
Explanation:
<u>Factoring</u>
It consists of converting an algebraic expression, usually as a polynomial into two or more factored terms.
We must find the greatest possible common factor and use it to modify the original expression.
The given expression is

It's evident that both terms have a numeric common factor of -9. Let's factor by -9. We must divide each term by -9 to get:

We can even factor further by writing
