Dunas are dinamic formations created by wind material deposits. They have a particular shape defined by windward and leeward sides. The correct option is B. windward and leeward.
<h3>
What is a dune?</h3>
Dunes are wind deposits, formations that are typical of deserts.
Dunes are orientated according to the direction and speed of winds and the presence of loose material and vegetation. Strong winds transport sand until it collides with an object or obstacle, where it is deposited, creating a new dune.
Dunes are very dynamic formations that are constantly, being remodeled by the direction and strength of the winds. They always have a soft slope (windward side) and a sharp one (leeward side).
- The windward side faces the direction where the wind is coming from and is the product of the wind erosion on the same dune.
- The opposite leeward side is protected from the wind and is the deposition place, where the wind losses strength and the carrying material falls, depositing on this side of the dune.
The correct option is B. windward and leeward.

The answer is adenine.
The nitrogenous base pairings are always adenine with thymine and cytosine with guanine.
I remember this as
· the two round letters (C and G) pair together
· the two straight-edged letters (A and T) pair together
Hopefully that helps.

Stellar evolution is the process by which a star undergoes a sequence of radical changes during its lifetime. Depending on the mass of the star, this lifetime ranges from only a few million years (for the most massive) to trillions of years (for the less massive), considerably more than the age of the universe. ^
Small, relatively cold, low mass red dwarfs burn hydrogen slowly and will burn for hundreds of billions of years
Massive hot supergiants will live for just a few million years.
A mid-sized star like the Sun will remain on the main sequence for about 10 billion years. Hope tis helps!!
