50. because its 140 in 1991 and about 90 in 1992.
-2m<5k+10-18d-9k
-2m<-4k-18d+10
-m<2(-2k-9d+5)/2
-m<-2k-9d+5
m>2k+9d-5 (when divided by -1 the inequality changes)
c is anwer
Can you provide more information please
Answer:
As a fertilized egg divides, the cells differentiate because they have to become [different] specialized cells to perform different functions.
Explanation:
The molecules of DNA of a human have to be duplicated over end over so that every human’s cell contains a copy of DNA that can be found in a fertilized egg.
When cell differentiates, the embryonic cell becomes a specialized cell. This leads to an expression of gens and that is what dictates the functioning of one cell.
The answer is d. Thank you :)))
