What kind of map might have diagrams of air pressure? a. isobar map c. satellite map b. topographic map d. synoptic map

Option A , Isobar Map

Explanation:

An isobar is a diagram that represents point of equal pressure. Thus, option A is correct. Isobars are basically lines that connects all points of equal air pressure

While a synoptic map represents weather pattern of a large area by combining different weather reports. A topographic map represents the geographical features of a land. and a satellite map shows different aspects at a time such as altitude, depth, peaks etc.

Hence, option A is correct

Good morning, Damonturner535 Have a great day!!

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
