The answer top the question given above is letter c. Surface currents.
There are two types of ocean currents, surface current and deep currents.
Surface currents which are caused by winds,move warm water
away from the equator and cool water away from the poles. Deep currents on the other hand are driven by differences in water density.
For centuries scientists thought the Universe always existed in a largely unchanged form, run like clockwork thanks to the laws of physics. But a Belgian priest and scientist called George Lemaitre put forward another idea. In 1927, he proposed that the Universe began as a large, pregnant and primeval atom, exploding and sending out the smaller atoms that we see today.
His idea went largely unnoticed. But in 1929 astronomer Edwin Hubble discovered that the Universe isn’t static but is in fact expanding. If so, some scientists reasoned that if you rewound the Universe's life then at some point it should have existed as a tiny, dense point. Critics dismissed this: the celebrated astronomer Fred Hoyle sarcastically called this concept the “Big Bang Theory"
Answer:
False
Explanation:
In DNA, there are four possible nitrogen bases – adenine (A), guanine (G), cytosine (C), and thymine (T). In DNA, nucleotides combine to form two long chains that intertwine with each other, like a ladder that has twisted into a spiral.
