thousands of years
Explanation:
A delta the size of the Mississippi River will take several thousand of years to form because the process of formation of a delta is geologically controlled.
A delta is a place where river enters or drains into the sea with many mouth or outlets.
Deltas are depositional terrain full of dis-tributaries.
- For a delta to form, a terrain must be close to the mouth of an ocean or a larger body of water.
- The entering stream must be large enough and have large amount of sediment.
- The river mouth must have been cut to the same level with that of the drainage basin.
- Most rivers such terrain should be at their lower course where they flow with very low velocity.
- Wave action should be minimal along such coasts.
These processes takes several thousands of years if not millions.

Answer:
Only A
Explanation:
RNA is used for storing and transporting information through mostly virus only..
In flowering plants the gametophyte phases are reduced to a few cells dependant for their nutrition on the Sporophyte. The gametophyte comprises the main plant, while the diploid sporophyte is much smaller and is attached to the gametophyte. Both spores and the resulting ganetophyte are haploid, which means they only have one set of chromosomes. The mature gametophyte produces male or female gametes by mitosis. The fusion of male and female gametes produces a diploid zygote which then develops into a new sporophyte.
Answer:The epiphyseal of the boy's long bones have closed
Explanation: Epiphyseal plates is a part of a long bone,were new bone growths take place. Puberty is the transitional period from childhood to adulthood,through the development of sexual characteristics. In early puberty the height of a child increase,this is called growth spurt. This growth spurt may decrease in late puberty after epiphyseal fission in late puberty,that is, after growth plate closure in late puberty.
