Here's it! Good Luck!
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, after Mercury. Named after the Roman god of war, it is often referred to as the "Red Planet" because the iron oxide prevalent on its surface gives it a reddish appearance. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth.
The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Mars is the site of Olympus Mons, the largest volcano, and second-highest known mountain in the Solar System, and of Valles Marineris, one of the largest canyons in the Solar System. The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature. Mars has two moons, Phobos and Deimos, which are small and irregularly shaped. These may be captured asteroids, similar to 5261 Eureka, a Mars trojan.

<span>The correct answer is desert biome.</span>
Deserts are regions also called drylands because of the conditions found there (like a moisture deficit). Desert plants have to adapt to those dry and hot climates (sometimes without fresh water for years). Some plants have adapted by growing long roots that tap water from deep underground. Others, such as cacti, have special means of storing and conserving water (modifications of leaves for example).

Explanation:
Hydrogen bonds are intermolecular powers; covalent and ionic bonds are intramolecular powers. Ionic bonds structure when one molecule moves electrons to another iota. The molecule that loses an electron turns into a positive particle.
