Proteins
synthesis requires transcription of DNA (containing information) to mRNA then
this goes out of the cell’s nucleus to cytoplasm; and translation of mRNA together
with ribosome and tRNA to synthesize proteins. Further steps are the following:
1)
One side of DNA strand is copied to become mRNA (messenger RNA).
2)
mRNA goes out the cell’s nucleus, next to cytoplasm and then to ribosome.
3)
mRNA works with ribosome’s 3 bases at the same time.
4)
tRNA (transfer RNA) connects with available DNA bases.
<span>5) tRNA
releases the amino acids which in turn combines with the other produced amino
acid chains from different DNAs. </span>
Answer:
The details about sugar's dependency on slavery help inform readers about why sugar was inexpensive.
Explanation:
In this text, the author explains that sugar was a cheap commodity during this time period. This was the case despite the fact that sugar was produced thousands of miles away. The main idea of this excerpt is that sugar was such an inexpensive good because it relied on slavery. By using free labor, production costs were kept extremely low, allowing for sugar to be inexpensive, and therefore, popular all over the world.

Measles are a viral infection that causes skin eruptions.
Answer: The uses are as follows :D
1. Lithium: heat resistive ceramics, aircraft building, tritium production
2. sodium: coolant in nuclear reactors, soap making, street light manufacture (e.g. sodium vapor lamps)
3. Potassium: tanning of leather, manufacture of inks, making gunpowder
4. Rubidium: thermoelectric generator, making atomic clocks, working fluid in vapor turbines
5. Cesium: catalyst for hydrogenation of some organic compounds, vacuum tubes, photovoltaic cells
6. Francium: extremely radioactive and extremely rare so not used often
