Answer:
1 cm = 405 km
Explanation:
The scale of the map can be seen at the bottom-left corner of the map to be 1 cm = 405 km. This means that for every 1 cm on the map, the actual distance/length of a centimeter, the actual measurement on earth is 405 kilometers. All maps have usually have this scale to give a proper documentation/fact of what is been illustrated.
<h2>Answer:</h2><h2 /><h2>DNA molecules are a precursor to self-replicating RNA molecules, which are used to build proteins. Early RNA molecules were able to self-replicate, which helps to explain why all organisms share the same genetic code.</h2>
The statement 'artificial selection decreases the rate of natural selection and change within a population' describes how artificial selection can decrease a population's biodiversity. It is a human-driven process.
<h3>Artificial selection</h3>
Artificial selection refers to the human-driven process by which different organisms (either plants or animals) are selected in order to combine desired features in offspring.
In artificial selection, organisms are mated (crossed) in order to select the progeny having desired phenotypic traits.
This process (artificial selection) leads to a decrease in natural genetic variation (biodiversity), which may have negative consequences in the successive rounds of selection.

B. I think I'm not so sure but that's my best guess.
