In excreted urine, a reliable "marker" that a pregnancy has initiated is human chorionic gonadotropin (hCG).
<h3>
What is human chorionic gonadotropin?</h3>
- The trophoblast cells that surround a developing embryo.
- Eventually give rise to the placenta after implantation generate the hormone known as human chorionic gonadotropin, which helps women recognize pregnancy.
- Some pregnancy tests can detect the HCG's presence.
- The placenta secretes a hormone known as human chorionic gonadotropin throughout pregnancy (HCG).
- It tells the body to stop menstruation and makes the uterine lining thicker to support an embryo in development.
- After fertilization, HCG levels increase and stay elevated for another 10 weeks or more of pregnancy.
- As accurate as blood tests are urine testing.
- An individual is pregnant if their HCG level is high.
- An individual is not pregnant if a qualitative HCG test is negative.
- After a few days, a person should repeat the test if they still believe they are pregnant.

Answer:
Continental <u>Polar</u>
Explanation:
Air masses are given a <u>two-part name</u> that describes the humidity and temperature characteristics of the region where they form. The first part of an air mass’ name describes its humidity. Air masses that form over the ocean, called maritime air masses, are more humid than those that form over land, called continental air masses. The second part of the name describes the temperature of the air mass, which depends on the latitude where it formed. Air masses that form near the equator or in the tropics (equatorial or tropical air masses) are warmer than air masses that form in polar areas or uin the Arctic (polar or arctic air masses).
The word that describes humidity (maritime or continental) is paired with the word that describes temperature (equatorial, tropical, polar or arctic). For example, if an air mass forms over a tropical ocean, it is called maritime tropical. If an air mass forms over land in the far north it is called continental polar.
