The correct answer is Birth.
The two elements that raise population size are natality—the number of people who are added to a population over time as a result of reproduction—and immigration—the movement of people into a location. Most births are to folks who are young adults or older. Even at replacement fertility levels (when each woman has approximately an average of two children), there will be more births than deaths if the proportion of young adults to older adults is higher where mortality is highest. Immigration and birth rates lead to population growth. The population shrinks as a result of death rates and emigration. A population that has a negative growth rate is one in which there are more deaths and emigrants than births.

Answer:
1. Roche limit
2. hydrogen
3. atmosphere
4. Mercury
5. Venus
6. When an object passes the Roche limit, the strength of gravity on the object increases. If the density of the planet is higher, then the object can break up farther away from the planet. If the density is lower, then the Roche limit is located closer to the planet.
7. Farther out in the solar system, beyond the frost line, hydrogen was at a low enough temperature that it could condense. This allowed hydrogen to accumulate under gravity, eventually forming the Jovian planets.

If the pulmonary artery is blocked, blood would go back up to the right ventricle of the heart.
<h3>What is pulmonary artery stenosis? </h3>
The pulmonary artery is responsible for carrying the deoxygenated blood from the right ventricle of the heart to the lungs to get oxygenated.
Pulmonary artery stenosis is a condition in which the pulmonary artery gets narrowed or blocked. Therefore, blood flow from the heart to the lungs is hampered.
This creates pressure on the walls of the heart. Also, if blood flow towards the lungs is hampered, the heart will not receive the required amount of oxygen. All of this will lead to damage to the heart muscles over the course of time.
Therefore, as a result of the pulmonary blockage, blood would first back up into the right ventricle.

Answer:
The correct answer will be option-Base analog
Explanation:
5-bromodeoxyuridine is a synthetic nucleoside which is formed by deaminating the 5-Bromodeoxycytidine.
The BrdU once incorporated in the DNA of replicating cell during S phase binds the adenine which shows that it replaces the thymidine which usually binds the adenine.
Since BrdU binds the adenine, therefore, it acts as the analogue of the thymidine and also can cause mutations thus acts as a mutagen.
Therefore, it acts as a base analog and thus is the correct answer.
