What is the primary reason slugs gather together beneath rocks?

• For protection from predators.

• To find food more easily.

• To regulate their body temperature.

• To attract mates.

Define cell specialization.

• The process by which generic cells change into specific cells meant to do specific tasks.

• The ability of cells to replicate indefinitely without changing their function.

• The mechanism by which cells communicate with each other through chemical signals.

• The process of cell division that results in two identical daughter cells.

What is the likely ecological effect of migratory shore birds preying on octopus populations?

• An increase in the sea snail population.

• A decrease in fish populations.

• An increase in octopus populations.

• A decline in shore bird populations.

What is biodiversity?

• The total number of species in a given area.

• The variety of life in the world or in a particular habitat or ecosystem.

• The number of individuals of a single species in an ecosystem.

• The genetic variation within a single species.

What structure captures energy during photosynthesis and what molecule stores that energy?

• Chloroplast captures and glucose stores.

• Mitochondria captures and ATP stores.

• Nucleus captures and DNA stores.

• Ribosome captures and protein stores.

What is an ecosystem?

• A biological community of interacting organisms and their physical environment.

• A type of climate zone characterized by specific weather patterns.

• A group of species that share the same habitat but do not interact.

• A collection of non-living things in a specific area.

Which kingdom is most closely related to kingdom Fungi?

• Kingdom Plantae

• Kingdom Animalia

• Kingdom Protista

• Kingdom Bacteria

Why do cells in zygotes eventually form specific cells?

• Cell specialization is necessary to form tissues.

• All cells in zygotes remain identical throughout development.

• Zygotes do not undergo any changes after formation.

• Cells in zygotes only divide without specialization.

What is photosynthesis?

• The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

• A method used by animals to convert food into energy.

• The way in which plants absorb water from the soil.

• A chemical reaction that occurs in the dark to produce energy.

What is the relationship between predator and prey populations?

• Predator populations can control the size of prey populations, leading to ecological balance.

• Prey populations can control the size of predator populations, leading to ecological imbalance.

• Predators and prey populations are independent of each other and do not affect one another.

• Predator populations are always larger than prey populations.
