What two things lead to genetic variation
vredina [299]

Answer:

Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. Another source is gene flow, or the movement of genes between different groups of organisms. Finally, genetic variation can be a result of sexual reproduction, which leads to the creation of new combinations of genes.

How many ml of a 2.903 M NaOH solution are needed to produce 500.0 ml of a 0.3344M solution?
levacccp [35]

Answer:

57.6ml

Explanation:

Using dilution formula

C1V1 = C2V2

C1 = 2.903 M, V1 = ? , C2 = 0.3344 M , V2 = 500ml

2.903 × V1 = 0.3344 × 500

V1 =( 0.3344 × 500)/ 2.903

= 57.5956

≈ 57.6ml
