BIOLOGY STAAR REVIEW

What is the second step of protein synthesis?

• Transcription

• Translation

• Replication

• Modification

What is the role of chloroplasts?

• To conduct photosynthesis in plant cells.

• To store genetic information in cells.

• To provide structural support to plant cells.

• To facilitate cellular respiration in plant cells.

In a energy pyramid, what organism receives the most energy?

• The primary consumers, they eat the producers

• The secondary consumers, they eat the primary consumers

• The producers, they get their energy directly from the sun

• The decomposers, they break down dead organisms

What is the function of the cell membrane in all cells?

• Transporting nutrients into the cell.

• Producing energy for the cell.

• Maintaining homeostasis.

• Storing genetic information.

What is the relationship between photosynthesis and cellular respiration?

• The products of photosynthesis are used in cellular respiration, and the products from cellular respiration are used for photosynthesis.

• Photosynthesis occurs only in plants, while cellular respiration occurs in all living organisms.

• Photosynthesis and cellular respiration are completely unrelated processes.

• Photosynthesis produces energy, while cellular respiration consumes energy.

What symbiotic relationship occurs when both organisms benefit?

• Commensalism

• Parasitism

• Mutualism

• Predation

How can scientists determine relatedness among organisms?

• By comparing partial amino acid sequences.

• By analyzing the color patterns of organisms.

• By studying the habitat preferences of organisms.

• By observing the behavior of organisms in the wild.

What are the building blocks of lipids?

• Amino acids and nucleotides.

• Fatty acids and glycerol.

• Monosaccharides and polysaccharides.

• Vitamins and minerals.

The theory of evolution comes from the main idea that..

• All species share a common ancestor

• Species evolve independently without any relation

• Evolution is driven solely by environmental factors

• Species are created separately and do not change over time

What is the primary function of proteins?

• To provide energy for cellular processes.

• To perform a variety of functions including catalyzing reactions, providing structure, and regulating processes.

• To store genetic information.

• To transport oxygen in the blood.
