Answer:

If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). If a cell is in a hypertonic solution, the solution has a lower water concentration than the cell cytosol does, and water moves out of the cell until both solutions are isotonic.

Explanation:

If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ).

explain what determines the sex chromosome in males and females. explain what determines the sex of a baby

Law Incorporation [45]

Answer:

The sex chromosomes are referred to as X and Y, and their combination determines a person's sex. Typically, human females have two X chromosomes while males possess an XY pairing. This XY sex-determination system is found in most mammals as well as some reptiles and plants.

Men determine the sex of a baby depending on whether their sperm is carrying an X or Y chromosome. An X chromosome combines with the mother's X chromosome to make a baby girl (XX) and a Y chromosome will combine with the mother's to make a boy.

Answer:

The one treated with DNase and protease

Explanation:

The samples that will transform yellow into purple if RNA is the genetic material are the ones treated with DNase and protease respectively.

The treatment of the heat-killed sample of the purple life with DNase will ensure that the DNA in the sample becomes degraded while treatment with protease will ensure that protein is degraded, leaving only the RNA. Thus, the RNA can be taken up by the yellow life form and become transformed into purple if indeed RNA is the genetic material.

The sample treated with RNase cannot transform the yellow life into purple because the RNase catalyzes the degradation of RNA into smaller components.
