TEAS TEAS-SECTION-2 - Questions & Answers

The cellular hierarchy starts with the cell, the simplest structure, and progresses to organisms, the most complex structures.

A hypertonic solution is a solution with a higher particle concentration than in the cell, and consequently lower water content than in the cell. Water moves from the cell to the solution, causing the cell to experience water loss and shrink.

Interphase is the period when the DNA is replicated (or when the chromosomes are replicated) and is the longest part of the cell cycle.

Recessive alleles are represented by lower case letters, while dominant alleles are represented by upper case letters.

Dominant genes are always expressed when both alleles are dominant (BB) or when one is dominant and one is recessive (Bg).
In this case, 3/4 or 75% will have brown eyes.

Groups of cells that perform the same function are called tissues.

The nuclear division of somatic cells takes place during mitosis.

The immune system consists of the lymphatic system, spleen, tonsils, thymus and bone marrow.

The rate at which a chemical reaction occurs does not depend on the amount of mass lost, since the law of conservation of mass (or matter) states that in a chemical reaction there is no loss of mass.

Boyle's law states that for a constant mass and temperature, pressure and volume are related inversely to one another: PV = c, where c = constant.
