That DNA is a double helical structure and acidic in nature and it is present inside the chromosomes as it is coiled around histone protein which is basic in nature. That allows the DNA to fits in the nucleus.
Thus, the 3rd statement is the correct answer.
The phase transition in which molecules directly move from a state involving vibration of particles in a fixed position to a state involving random movement of high -speed particles is called : Sublimation
Particles in a fixed position = solid particle
Random movement high speed particles = gas particles
The transition from solid to gas is called sublimation
hope this helps
Explanation:
Environmental exposure to certain chemicals, ultraviolet radiation, or other external factors.
<h2>Answer is option "c"</h2>
Explanation:
- Earth is the main planet in the solar system with a climate that can continue life. The cover of gases contains the air that we inhale as well as shields us from the impacts of warmth and radiation exuding from the sun. It warms the planet by day and cools it around evening time.
- Earth can bolster a wide assortment of living creatures in view of its different territorial atmospheres, which run from the outrageous cold at the posts to tropical warmth at the Equator.

- Earth's worldwide atmosphere is normal of territorial atmospheres. The worldwide atmosphere has cooled and warmed since the beginning. Today, we are seeing strangely fast warming. The logical accord is that ozone harming substances, which are expanding a result of human exercises, are catching heat in the atmosphere.
- Hence, the right answer is option c " reduces the temperature extremes between day and night recycles."
