Humans have a gene, "T" that is involved in muscle formation of the tongue. Individuals with the one allele can roll their tongu
zhuklara [117]

Answer:

Tongue-rolling is dominant, and both parents were heterozygous

Explanation:

Tongue rolling is a type of variation in human beings. When allelic genes are not identical as in Tt, the condition is referred to as heterozygous. An individual with such a genotypic condition is referred to as a heterozygote.

Both parents had a genotype of Tt and they could roll their tongues because T is dominant over the t gene.

              T     t

  T         TT   Tt

   t         Tt     tt

TT : Tt : tt

1 : 2 : 1

In a heterozygous parent Tt, the chance of producing T gamete from both parents is each 1/2 each. Similarly the chance of forming t gamete is 1/2. Therefore, the chance of gamete T and t fusing to get genotype Tt is 1/2*1/2=1/4.

The ratios of phenotypes are 3/4 will be able to roll the tongue and 1/4 will not be able to roll the tongue.

The mode of inheritance was monohybrid inheritance since one characteristic like tongue-rolling is controlled by a single pair of hereditary factors contributed by both parents.

The concentration of salt is higher inside a cell than outside the cell. The concentration of water inside the cell is lower tha
asambeis [7]

Answer:

C. Water will move into the cell through osmosis. The salt and water concentrations will become similar inside and outside the cell.

Explanation:

Osmosis is the movement of water from its higher concentration to the lower concentration through a semi permeable membrane. Here, the cell have higher salt concentration and lower water concentration as compared to its outside. Since cell membrane is semi permeable, salt cannot pass through it. So, water will move into the cell through osmosis to equalize the salt and water concentration on either side of cell membrane.
