NC EOC Biology Exam Preparation Quiz

The characteristics of life include organization, energy utilization, growth, reproduction, and response to environment. Having a rigid structure, staying in a fixed state, and remaining unchanging are not accurate characteristics of life.

The suffix -ase is commonly used in biochemistry to indicate an enzyme.

Organic compounds are primarily composed of carbon and hydrogen atoms, with other elements such as oxygen, nitrogen, sulfur, and phosphorus also commonly present but not essential for classification as organic.

Covalent bonding involves the sharing of electrons between atoms to stabilize molecules, making it the strongest type of chemical bond. Protons do not typically participate in bonding, ions form ionic compounds through transfer of electrons, and neutrons do not play a role in chemical bonding.

The pH scale ranges from 0 to 14, with acidic substances falling between 0 to 6, basic substances falling between 8 to 14, and neutral substances having a pH of 7.

The Brown Paper Test for lipids typically results in a translucent appearance when lipids are present.

The six kingdoms classification system includes Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia. Monera, Chromista, and Parazoa are not part of the six kingdoms classification.

Eukaryotes are organisms whose cells have a nucleus and other membrane-bound organelles, distinguishing them from prokaryotes. They can be single-celled or multicellular and include plants, animals, fungi, and protists.

Prokaryotes are characterized by their lack of a true nucleus and other membrane-bound organelles, making them distinct from eukaryotic cells. They are typically small and have a simple cell structure.

The three domains of life include Archaebacteria, Eubacteria, and Eukarya. Protista, Fungi, and Plantae are all part of the Eukarya domain.

In photosynthesis, green plants use sunlight to convert carbon dioxide (CO2) and water (H2O) into glucose (C6H12O6) and oxygen (O2). The equation represents the balanced chemical reaction that occurs during photosynthesis.

Archaebacteria are a group of single-celled microorganisms that thrive in extreme environments. Methanogens and thermophiles are examples of Archaebacteria because they can be found in environments such as hot springs and deep-sea hydrothermal vents.

E. coli is a commonly known example of Eubacteria, while Streptococcus, Salmonella, and Clostridium belong to different bacterial groups.

Protista is a diverse group of eukaryotic microorganisms that includes unicellular organisms like amoeba, while earthworm, sunflower, and goldfish belong to different kingdoms and are not considered Protista.

Fungi are organisms such as mushrooms that belong to a separate kingdom from plants and animals. While mushrooms are examples of fungi, apples, dogs, and roses are not considered fungi.

Plantae is one of the five kingdoms in biological classification, consisting of multicellular organisms that typically produce their own food through photosynthesis. A plant is a member of the Plantae kingdom, while a dog is an animal, a rock is an inanimate object, and bacteria belong to the Monera kingdom.

Animalia is a kingdom in the biological classification system that includes animals. Humans belong to this kingdom, while plants, bacteria, and fungi belong to different kingdoms such as Plantae, Bacteria, and Fungi, respectively.

Taxonomy is the branch of science concerned with the classification of organisms based on shared characteristics.

Phylogeny refers to the evolutionary history and relationships among organisms, often depicted in the form of a phylogenetic tree.

The scientific method involves a series of steps that ensure proper testing and analysis of hypotheses in order to draw reliable conclusions. Making assumptions without testing, skipping data analysis, and keeping experimental conditions uncontrolled would undermine the validity and credibility of the scientific process.

Ecology specifically focuses on the interactions between living organisms and their environment, making it distinct from the other incorrect options provided.

Biotic factors refer to all living organisms and their relationships within an ecosystem, not just physical or non-living factors. It encompasses the entire biological component of an ecosystem.

Abiotic factors are specifically non-living components of an ecosystem, such as sunlight, temperature, water, soil, etc. They do not include living organisms.

A niche refers to an organism's role and position within its ecosystem, not to be confused with other definitions such as a physical indentation, a type of fruit, or a style of music.

A food chain refers to the transfer of energy and nutrients through consumption, where organisms in an ecosystem are connected through their feeding habits.

A food web is a network of interconnected food chains, showing the flow of energy within an ecosystem.

Carrying capacity refers to the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment.

The levels of organization in biology range from the smallest unit, cells, to the highest level, biosphere, encompassing all ecosystems on Earth. Molecules and atoms are smaller units below the cellular level, while organelles are found within cells.

The respiration equation shows the chemical reaction during cellular respiration where glucose (C6H12O6) and oxygen (O2) react to produce carbon dioxide (CO2) and water (H2O). This process releases energy for the cell to use.
