If the environment outside a cell is hypertonic, how will the cell maintain homeostasis?
USPshnik [31]

Answer:  Water will move outside of the cell.

Homeostasis is the ability of the cell to maintain the state of balance despite of changing external environmental conditions. Osmotic pressure is the hydrostatic pressure of water across the cell membrane. Tonicity is the measurement of this pressure. If the concentration of solutes on both sides of the membrane is equal then water will not move across the membrane. Osmotic pressure maintains the homeostasis of the cell. In hypertonicity osmotic pressure of the solution outside the cell is higher than the inside the cell. The water inside the cell will exit the cells in order to equalize the osmotic pressure on both sides, causing the cells to shrink.

The DNA sequence TTG is changed to TCG and produces a new protein. Which type of mutation is this?
konstantin123 [22]

Answer: missense

Explanation:A missense mutation is a type of mutation in which there is a change in one single nucleotide in a DNA sequence which results in an altered mRNA sequence and consequent incorporation of wrong amino acid into the amino acid sequence of a protein. The single nucleotide change in DNA results in a different codon on the mRNA sequence and this leads to production of a protein that is different from the original protein. This change can affect the function of the protein, in most cases it makes the protein nonfunctional.
