Each element absorbs light at specific wavelengths unique to that atom. When astronomers look at an object's spectrum, they can determine its composition based on these wavelengths. The most common method astronomers use to determine the composition of stars, planets, and other objects is spectroscopy.

1. What characteristics do the mountains in a mountain range have in common?
lesantik [10]

Answer:

Mountains are prominent landforms that have significant heights above sea level and/or the surrounding land. They are steeper than hills. A mountain or mountain range usually has a peak, which is a pointed top. Mountains have different climates than land at sea level and nearby flat land. Climate is the weather over an extended time period for a specific area. The climate of mountains tends to include colder weather, wetter weather, and thinner air. Thin air refers to the fact that at the higher altitudes of a mountain there is less oxygen to breathe. Also, mountains generally have less hospitable conditions for plants and animals. This leads to quite different evolutionary adaptations for those plants and animals that make higher elevations their home.

motikmotik
<span><span>Mitosis is the process in which cells divide to form new cells. The cell that is being described under the microscope is already in the Anaphase stage in mitosis.

Anaphase is the process in which two sister chromatids separate and move to opposite poles of the cell. These two sister chromatids contain identical copies of DNA that are joined at the middle called centromere. The chromosomes are separated by the mitotic spindle. Towards the end of the anaphase</span> the two sister chromatids now have their two separate poles. The mitotic process then proceeds to the Telophase.</span>

The "rod-cone break" in the dark adaptation curve occurs after about ____ in the dark.
emmainna [20.7K]
The correct answer is "<span>7 minutes".

The Rod-Cone-Break is considered to be a d</span>ark environment adaptation function in the eye, wherein for an estimated time of the first ten minutes in the dark, the cones<span> needs less light to reach a threshold response than do the </span>rods<span>. Thereafter, the </span>rods<span> need less light. The point at which the </span>rods<span> become more sensitive is called the </span>rod-cone break<span>.</span>
