PSYCHO15rus [73]

Explanation:

A frameshift mutation  is an insertion or deletion in a sequence of DNA which disrupts the way the code is read. It occurs when the codons undergo a disruption through the deletion or insertion of one or multiple nucleotides (given that the number removed or added are not multiples of 3) - this alters the open reading frame; the amino acids produced through translation simply occur in a different sequence.

Further Explanation:

During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:

  • somatic: these only occur within certain cells, and arise from environmental factors such as UV light
  • hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.

8_murik_8 [283]

Answer: osmosis

Explanation: osmosis is the movement of the water molecules from a region of high concentration of solute to a region of low concentration of solute, through a semi-permeable membrane.

This movement occurs until the concentration on both sides is on equilibrium.

Semi permeable membrane allows the movement of water only but not the solute.

In this case,water moves from region A to region B.
