Enhancers work by serving as binding sites for transcription factors--proteins that regulate transcription.<span> Enhancers lead to the production of regulatory proteins. The proteins bind to regulatory sites of DNA, triggering transcription of cell-specific proteins.</span>
Answer:
A. Scientists discovered chromosomes and DNA.
Explanation:
Mendel's ideas were based on patterns of inheritance in plants. Although he identified these patterns, at the time, we did not know what the hereditary material was. This means Mendel couldn't uncover the mechanism of why he was seeing the patterns he was.
When scientists discovered chromosomes and DNA, they were able to see how Mendel's observations made sense in the context of DNA and chromosomes.
You are supposed to answer what happens in each phase of meiosis.
The answer is B.
Water in the form of vapor enter the atmosphere. The vapor accumulates in the atmosphere to form clouds. Once the clouds are heavy enough, the water in the form of droplets fall towards land or as rain. It could also be in the form of other precipitation such as snow or hail. As the sun hits the waters in the land, it causes the water to evaporate and the cycle continues.
