Circumpolar. Circumpolar constellations are visible all year round. In the northern hemisphere, the famous circumpolar constellation is Ursa Major (The Big Dipper) which rotates around the North Star Polaris which always stays in the same place.
Answer:
The correct answers are- a) In the deformed mice, somatic cells but not germ cells were mutated and d) The toxic chemical affects development but is not mutagenic.
Explanation:
Mutation in the somatic cells do not pass in the offsprings and the only mutation in the germ cells can pass to the offspring because offspring are produced by the fertilization between different germ cells. Somatic cell mutation can only cause deformation in individuals but their offspring will be like normal offsprings.
The other cause may be that the toxic chemical used don't cause any mutation but just affect the development of mice so in this case genetic material will remain in normal state in deformed mouse and they will able to produce normal offsprings. So the right answer is a and d.
Answer:
Explanation:
In the Precipitation Map of Washington, the dark orange section indicates low rainfall in the region. Using the Shaded Relief Map of Washington, you can tell that this area is flat, possibly a plain. These areas normally don't get a lot of moisture. The Washington Precipitation Map has regions that are dark purple and dark orange. This means that they both get a lot of rain every year. If you look at these areas on the Washington Shaded Relief Map, you can see that these areas with a lot of rainfall are mountainous.
On the Washington Precipitation Diagram, purple/blue means more rain, and orange/red means less rain. Washington's Shaded Relief Map shows the mountains (br)
Answer:
Antony Van Leeuwenhoek
Explanation:
Discovering bacteria and creating more than 500 simple microscopes
Epigenetic is the study in the field of genetics of cellular and physiological phenotypic trait variations that are caused by external or environmental factors that switch genes on and of and affects how cells read genes instead of being caused by changes in the DNA sequence. Therefore, hence epigenetic research seeks to describe dynamic alterations in the transcriptional potential of a cell.
Hope this helps you!
