Maria and craters are explained below:
<u>Explanation:
</u>
- The Moon is divided into light area lunar highlands and a dark area called Lunar Maria.
- Lunar Maria is large, dark, basaltic plains formed on earth's moon formed by ancient volcanic eruptions.
- Craters are formed when an impacting object falls and hits the moon's surface with greater speed and also formed as a result of the outward explosion of rocks.
- Craters are often caused by asteroids and meteorites with the lunar surface.
- Unlike earth-moon does not have an atmosphere to protect itself from impacting bodies. This is the reason for more number of craters formed on earth.
-it’s an area around the pacific ocean with a lot of volcanic activity. ( or you can say )- two thirds of active volcanoes are found in an area around the edges of the pacific ocean, these volcanoes form a ring that volcanologists called ring of fire.
hope this helped..!
Answer:
A sister chromatid refers to the identical copies (chromatids) formed by DNA replication of a chromosome, with both copies joined by a common centromere.
Explanation:
Homologous chromosomes may or may not be the same as each other because they are derived from different parents.
There are choices for this question namely:
<span>right primary
right secondary
left secondary
left primary
</span>
The correct answer is "right primary" or the right main bronchus. Anatomically, the right main bronchus has a larger diameter and a steeper angle (to compensate for the location of the liver). When a foreign body is accidentally aspirated, most commonly, it will lodge on the right main bronchus; especially in children.
