Biology STAAR Review

Which body systems are directly responsible for regulating these nodes and protecting the body from harmful materials in tissue fluid?

• Nervous and endocrine systems

• Respiratory and circulatory systems

• Immune and lymphatic systems

• Digestive and excretory systems

What will happen to the ecosystem if predators have fewer prey?

• The ecosystem will become unstable because predators will have fewer prey, the birds will have fewer nesting sites, and the area downriver will become vulnerable to flooding without the burrows to aerate the soil and provide drainage for monsoon rains.

• The ecosystem will thrive as new species will emerge to fill the gap left by the predators.

• The ecosystem will remain stable as other food sources will compensate for the loss of prey.

• The ecosystem will become more diverse as competition among species increases.

The sequence of nitrogenous bases in DNA is most important for which of the following?

• Providing the instructions for the traits of the organism

• Preventing mutations from occurring during DNA replication

• Allowing the DNA to have the shape necessary for replication

• Helping form the sugar-phosphate backbone of DNA molecules

Cells can generate as many 36 to 38 molecules of ATP from the mechanism of one molecule of glucose. Which cellular process results in this amount of ATP production?

• Anaerobic respiration

• Fermentation

• Aerobic cellular respiration

• Glycolysis

Which group of organelles is directly responsible for the production of new molecules within a cell?

• Mitochondria, lysosomes, and peroxisomes

• Ribosomes, the endoplasmic reticulum, and Golgi apparatus

• Nucleus, cytoplasm, and plasma membrane

• Centrioles, vacuoles, and cytoskeleton

• 50 joules

• 100 joules

• 200 joules

Five general characteristics of organisms in kingdoms Plantae or Fungi are listed in the box. Which table correctly lists the characteristics of the organisms in the two kingdoms?

• Table A: Multicellular, Photosynthetic, Cell walls made of cellulose, Reproduce sexually and asexually, Eukaryotic

• Table B: Unicellular, Heterotrophic, Cell walls made of chitin, Reproduce only asexually, Prokaryotic

• Table C: Multicellular, Heterotrophic, Cell walls made of chitin, Reproduce sexually, Eukaryotic

• Table D: Multicellular, Photosynthetic, Cell walls made of cellulose, Reproduce sexually, Eukaryotic

A prey population consists of individuals with a variety of running speeds. The adaptation that allows some of these animals to run fast would be an example of natural selection if it helps them

• survive in their environment

• find food more easily

• reproduce and increase the frequency of their genes in the population

• escape from predators more effectively
