Answer:
The nucleus houses the genetic material of the cell: DNA. DNA is normally found as a loosely contained structure called chromatin within the nucleus, where it is wound up and associated with a variety of histone proteins. When a cell is about to divide, the chromatin coils tightly and condenses to form chromosomes. hope this helped!
Explanation:
Certain genes/cells are activated/turned on (how ever you want to word it)
1. Their large ears help dissipate excess body heat on hot days in the desert.
2. The fennec fox seems to be the only carnivore living in the Sahara Desert able to survive without free water. Their kidneys are adapted to restrict water loss, their extensive burrowing may cause the formation of dew, which can then be consumed, and they will receive moisture from the food that they eat.
3. Their burrowing and nocturnal lifestyle helps restrict water loss.
4. Their thick fur helps insulate them from the cold desert nights.
5. Their sandy fur helps to reflect heat, and also provides excellent camouflage.
6. Fennec foxes also have thick fur on the soles of their feet, which insulate against the hot sand of the desert. This extra fur on the soles of their feet also affords them excellent traction in the loose sand.
Answer:
NUMEROUS DISEASES SPREAD
Explanation:
When Columbus stumbled upon the Americas, he and his crew were carrying numerous diseases, including smallpox, which killed 50% - 90% of the Native people's population.
Answer:
attacks the outermost phosphorous group of the incoming nucleotide.
Explanation:
Transcription is the biological process where RNA is formed. As you may already know, RNA is an extremely important nucleic acid for genetic processes and the production of proteins. The transcription has three steps that are called start, elongation and end. In the elongation phase, the RNA strand is growing, at this time, RNA polymerase, which is the enzyme responsible for RNA elaboration, places the nucleotides, in the RNA strand, in the 5' - 3' direction. This enzyme causes the hydroxyl, which makes up the nucleotide at the 3' end of the forming RNA, to attack the phosphorus present in the incoming ribonucleotide.
