The element that is the most abundant in the Earth's crust is oxygen. It makes up 46.6% of the crust. It is followed by silicon, aluminum, iron, etc.
Answer:
Non-covalent interactions.
Explanation:
DNA is present as genetic material in all the living organism except some viruses. DNA also perform important other functions - code for proteins, used as a source of energy.
The DA binds with protein to perform their functions. These proteins may acts as activator for DNA. The proteins binds in the non covalent interactions ( ionic bonding, hydrogen bonding, vanderwalls and hydrophobic interaction) so that proteins may easily detach from the proteins. These interactions helps in the attachment and easily detachment of proteins from DNA.
Thus, the correct answer is non-covalent interaction.
Answer:
The correct match would be:
- Swallow - migration
- Tiger - sparse distribution—scarce
- Devil’s Hole pupfish - local endemic
- Humpback whale - sparse distribution—widely dispersed
Swallows are small migratory birds belonging to the family Hirundinidae found all around the world. Migrating swallows can cover around 200 miles in a day.
Tiger has become endangered species due to excessive hunting and habitat loss. It is estimated that only 3800 tigers are left in the wild.
Devil’s Hole pupfish is a species of a fish only found in Devils Hole which is a geothermal aquifer-fed pool located in Ash Meadows National Wildlife Refuge in Nevada city of the United States
The humpback whale or <em>Megaptera novaeangliae</em> is a species of baleen whale which is widely distributed in all major oceans including Pacific, Atlantic, and Indian oceans.
It would be A
First is: DNA > mRNA (messenger RNA) > tRNA (transfer RNA) > protein
