A table of arachnid and insect characteristics is shown. Which characteristic could be used to distinguish between arachnids and insects?

• Antennae are present.

• Legs are jointed

• Body is segmented

• Eyes are present

Plant cells have a strong, rigid outer layer known as the cell wall. The function of the cell wall is to

• convert energy from sunlight into chemical energy.

• regulate the movement of substances in and out of the cell.

• contain the genetic material for the cell.

• protect and support the cell.

The combination of a heart, arteries, veins and capillaries is -

• an organ system.

• a tissue.

• an organism.

• a cell.

Based on the collected data shown in the table, which part of the cell theory is best supported?

• Cells are the basic unit of living things.

Plants transport water upward from the roots to the stems and leaves through specialized structures called xylem. The xylem is made of a collection of many cells that join together to form microscopic tubes throughout the plant. Based on this description, xylem is classified as-

• a tissue.

• an organism.

• an organ system.

• an organ.

The stomach, small intestine, and large intestine are all organs. When these organs work together to process food, they form functional unit known as

• an organism.

• a tissue.

• a cell.

• an organ system.
