Answer:
The temperature of the Sun's middle most layer is 6,000 degrees Celsius to 20,000 degrees Celsius.
Explanation:
- The sun is basically divided into inner and outer layer.
- The inner layer consists of Core, Radiative Zone and Convection Zone.
- The outer layer has Photosphere, chromosphere, transition region and corona.
- The chromosphere is the middle layer that can vary its temperature 6,000 degrees Celsius to 20,000 degrees.
- For most reason the temperature of chromosphere can be taken around 7700 degree Celsius but it varies.
Answer:
I would say Phosphate Groups.
Explanation:
Nucleotides are joined together by covalent bonds between the phosphate group of one nucleotide and the third carbon atom of the pentose sugar in the next nucleotide.
Our muscles are attached to our skeleton to help us move. If we had no skeleton then our muscles would hang limply, making it harder for us to move.
I believe that the answer to this would be polar and hydrophilic (soluble in water). The answer would be the third option. What makes the head of a phospholipid hydrophilic is that its polar head is negatively-charged and made by a phosphate group. Hope this helps.
