Tonicity in cells depends on both the concentration of solute outside the cell and the concentration of solute inside the cell
Tonicity is a concept used in biology that defines the osmotic pressure ( pressure that stops the fluids from entering or leaving cells). This pressure is defined by the concentration of solute (substances dissolved in the liquid) outside and inside the cell.
In this context, the cell is classified as isotonic if there is a balance between the concentration outside and inside; hypertonic if the concentration outside the cell is higher, which causes the cell to shrink of hipotonic if the concentration outside is lower, which causes the cell to swell.

The answer for this question should be D) or the fourth option Protists.
Answer:
1) All of the above
Explanation:
Lamarck's theory of inheritance of acquired characteristics states that the physical changes in the body parts of an organism are inherited to their off spring from generation to generation. During his study of physical appearance ( phenotype) of organism Lamarck said that the characters adopted according to the changes in environment by organism as a physical change in body are inheritable e.g giraffes long neck due to shortage of food the giraffes in order to reach to higher trees had to make their neck long so their neck length was increased and they had long necks so the new offspring when burn had long necks so on this basis he said that the physical changes are inherited. Giraffes with long neck had more chances of survival in the environment.
Answer:
100%
Explanation:
The probability is shown by the punnet square below. While the genotype of 50% of the offspring may be heterozygous, since the allele for straight hair is dominant over that of curly hair, their phenotypes too will be of straight hair similar to the homozygous dominant offspring.
