Biology Week 2 EOC Review

Green algae grows on the back of spider crabs, which camouflages them. The crabs protect the algae. What type of relationship is this?

• Mutualism

• Commensalism

• Parasitism

• Competition

When a certain species of plant is without water for an extended period of time, guard cells close the stomata openings in the leaves of the plant. This activity conserves water and illustrates—

• An increase in growth due to low water concentration

• A response to a biotic factor

• Maintenance of homeostasis

• Cellular communication between immune system cells

• Thigmotropism

• Gravitropism

• Hydrotropism

Some organisms have genes that improve their ability to survive and reproduce. If the genes also help their offspring survive and reproduce, then which of the following will most likely increase?

During human gestation, the hormone oxytocin increase on the smooth muscle cells of the uterus. The release of oxytocin during labor stimulates the smooth muscle tissue in the wall of the uterus & contractions start. What body systems are working together?

• Integumentary, Skeletal, Muscular

• Reproductive, Skeletal, Integumentary

• Endocrine, Digestive, Excretory

• Reproductive, Endocrine, Muscular

Unlike protists, organisms in the group Animalia—

• Have cells with a cell wall and are heterotrophic

• Are complex and photosynthetic

• Have cells with no cell walls and have an organ system

• Are all mobile and autotrophic

Meiosis causes the offspring of organisms that have sexually reproduced to be genetically diverse. This is because meiosis produces:

• Genetically unique cells that will increase variation in a population

• Genetically identical cells that will not change the amount of variation

• Genetically identical cells that will decrease variation in a population

• Genetically unique cells that will decrease variation in a population
