Answer:

- The building blocks of DNA molecules are amino acids. False

- DNA molecules contain a 5-carbon sugar called deoxyribose. True

- The nitrogen bases found in DNA molecules include adenine, cytosine, guanine, and thymine. True

Explanation:

The building blocks of the deoxyribonucleic acid (DNA) are nucleotides, while amino acids are the building blocks of proteins. Each nucleotide consists of one of four possible nitrogenous bases: two purines (i.e., adenine and guanine) and two pyrimidines (i.e., cytosine and thymine). In DNA, each nucleotide consists of one of these four nitrogenous bases, a five-carbon sugar molecule (called deoxyribose), and a phosphate group. The DNA molecule has a double-helix structure, where nitrogenous bases are inside the double helix while sugars and phosphates are outside. In DNA, cytosine always pairs with guanine and thymine always pairs with adenine.

seraphim [82]

Answer:

Explanation:

The stars and moon are the celestial bodies which are located at distant.

The distance of stars vary but moon and sun remain same. As our Earth rotates at its own axis, other celestial bdies seem to move.

As Earth spins from west to east, the stars and moon seems to move from east to west direction at night and same with Sun, it also seem to move from east to west.

Hence, the correct option is east to west.

Discuss how scientists views on planetary paths have changed over time
Doss [256]

There were two approaches for the planetary paths. The idea about the planets revolving around the Earth, the planetary paths were plotted and were erratic. It was not relevant to the laws of motion and gravity. That fact was neglected by the believers in an Earth-centered Solar System. 

Sun-centered Solar System was theorized by Copernicus. The paths assumed to be relatively circular (or elliptical).
