Which type of solution will cause cells to swell, or even to burst?
Inga [223]

Answer:

(b) Hypotonic solution

Explanation:

  • Any solution having lower osmotic pressure as compared to another solution is called as a hypotonic solution and the reason that a solution is hypotonic is that it has more water and lesser dissolved solute in it.
  • If a cell is placed in a hypotonic solution, the amount of water content in the cell would be lesser as compared to that of the solution and hence, the water will enter the cell due to which the cell will swell and may even burst.
  • The water molecules can enter the cell through the semipermeable membrane and in case of plant cells, the presence of cell wall may prevent it bursting, however, the animal cells lack the cell wall and hence if kept in hypotonic solution for long these cells may burst.

Which is an example of a substitution mutation?
Marta_Voda [28]

Answer:

CAT - GGC - TAC mutates to CAT - GGC - TAG

Explanation:

Changes occur in the nucleotide sequence of the DNA molecule. These changes referred to as MUTATION are usually due mistakes during DNA replication or induced by mutagens (mutation-causing substances). Mutation can be of different types depending on the kind of change that occured to the nucleotide sequence. Based on this question, one of the mutation types is SUBSTITUTION MUTATION.

Substitution mutation is a kind of mutation in which one or more nucleotide base replaces another in the sequence.

The option that suits an example of substitution mutation is: CAT - GGC - TAC mutates to CAT - GGC - TAG because Guanine nucleotide replaces Cytosine nucleotide in the third CODON i.e. TAC becomes TAG.
