Why are we pulled to the center of the Earth and not into the much larger sun?

Answers

Answer:

The sun's gravity pulls on the earth, and the earth pulls back on the sun at the same time. This is why the center of the solar system is not the center of the sun. As one gravitational body gets bigger than the other, it circles closer to the center of the system (shown in red).

Explanation:

hope this helps...

The earth is known to be falling towards the sun as a result of intense gravity. The earth is known to have plenty of sideways momentum and due to this sideways momentum, the earth is often falling towards the sun and missing it.

The reason we are pulled to the center of the Earth and not into the much larger sun by gravity is that all objects with mass, like our Earth, do bend and curve the fabric of the universe referred to as spacetime.

At most, the gravity from the sun result in our planet moving in a curved, elliptical path. but, the planets are moving fast enough so that they are not pulled into the sun.

The sun has a more weaker gravity and as it loses mass, it causes the Earth to slowly move away from it.

Under each DNA sequence write the complimentary mRNA base sequence that each of these gene fragments would produce. Remember that in the production of mRNA, the DNA base sequence "A" _________________ specifies the RNA base ____________________

Answers

Answer:

The correct answer would be -

Thymine to adenine

Cytosine to guanine

guanine to cytosine

Adenine, and "U" uracil respectively.

Explanation:

mRNA is a sequence of complementary base sequences encoded from a gene or DNA segment which is used to produce the protein by the process called translation.

From converting a sequence from DNA to its complementary mRNA sequence, the rules of complementary base pairing will be applied: Cytosine (C) is replaced with Guanine (G) – and vice versa. Uracil (U) is replaced by Adenine (A) and Thymine is replaced by adenine.
