Answer:
nucleus
Explanation:
In organisms called eukaryotes, DNA is found inside a special area of the cell called the nucleus. Because the cell is very small, and because organisms have many DNA molecules per cell, each DNA molecule must be tightly packaged. This packaged form of the DNA is called a chromosome.
Answer:
The average size of the DNA fragments produced when this new DNA is cut by a restriction endonuclease with an eight-base recognition sequence would be 1679616.
Explanation:
Restriction enzymes can be described as the enzymes which are specific to certain DNA sites and cut the DNA from that particular site.
Normally, the average size of a DNA fragment cut by a restriction enzyme is calculated by the formula 4^{no.of base recognition sequence}.
As the number of bases has changed to 6 and the restriction enzyme has eight base recognition site then the formula will be:
6^{no.of base recognition sequence}
i.e
6^{8} = 1679616
Answer:
Manatee (A)
Explanation: Looking the graphic, Manatees live near the Equator, where is "hot" water place, and if you notice the other place are near cold water where none of them will avoid it.
Greenhouse gases such as carbon dioxide trap heat, helping warm the globe. The surge in carbon dioxide levels due to human activity since the Industrial Revolution is now causing an overall warming of the planet that is having impacts around the globe. And the burning of fuel generates not only carbon dioxide, but also air pollutants that are harmful to human health.
