Chapter 1 Flashcards
Which is not a characteristic of all living organisms?
A. Growth and Development
B. Composed of multiple cells
C. Complex yet organized
D. Uses energy
B. Composed of multiple cells.
Because some organisms are singled celled
Place the following levels of levels of biological organization in order from smallest to largest: atom, biosphere, cell, ecosystem, molecule, organ, organism, population, and tissue. Which is the smallest level capable of demonstrating all of the characteristics of life.
Atom, molecule, cell, tissue, organ, organism, population, ecosystem, and biosphere. The cell can perform all aspects of life.
Plants use the process of photosynthesis to convert the energy in sunlight to chemical energy in the form of sugar. While doing so, they consume carbon dioxide and water and release oxygen. Explain how this process functions in both the cycling of chemical nutrients and the flow of energy through an ecosystem.
6CO2 + 6H2O>C6H12 + 6O2 (Formula for photosynthesis). It mobilizes the nutrients by turning C»CO2»C6H12O6.
How does natural selection cause a population to become adapted to its environment over time?
Those that can inherit certain traits are more prosperous in the local environment.
Which statement best describes the logic of the process of science?
A. If I generate a testable hypothesis, experiments and observations will support it.
B. If my prediction is correct it will lead to a testable hypothesis.
C. If my observations are accurate, they will support my hypothesis.
D. Test results may or may not support my hypothesis
D. Test results may or may not support my hypothesis.
Which statement best distinguishes hypothesis from theories in science?
A. Theories are hypotheses that have been proven.
B. Hypotheses are tentative guesses; theories are correct answers to questions about nature.
C. Hypotheses are usually narrow in scope; theories have broad explanatory power and are supported by a lot of evidence.
D. Hypotheses and theories mean essentially the same thing in science
C. Hypotheses are usually narrow in scope; theories have broad explanatory power and are supported by a lot of evidence.
__ is the core theme that unifies all areas of a Biology.
Evolution
What distinguishes fact from opinion
Facts can be proven. Opinions depends on the person.
Match each of the following terms to the phrase that best describes it.
A. Natural Selection. 1. A testable idea
B. Evolution 2. Descent with modification
C. Hypothesis. 3. Unequal reproductive success
D. Biosphere 4. All life supporting environments on earth
Natural Selection=Unequal reproductive success
Evolution=Descent with modification
Hypothesis=A testable idea
Biosphere=All life supporting environments on Earth
By comparing genes between green sea turtles and humans, insight can be gained into how those genes encode specific physical traits.
Genes encode info to create proteins which then produce physical traits.
Although green sea turtles consume a lot of vegetation, they get few nutrients from each mouthful, requiring them to graze frequently.
Sea turtles obtain both energy and molecular building blocks from the grass they consume.
As global climate changes green sea turtles alter many aspects of their behavior.
Interactions within biological systems: Chemicals released in one part of the world can interact with ocean water in another part, affecting the life found there.
Biosphere
The planet we call earth which all life exists.
Ecosystems
Components of the environment which is soil, water, and light as well as where all living organisms reside.
Communities
Collective organisms i.e Snakes, Cats, and Dogs
Populations
Groups of interacting individuals of one species.
Organisms
A singular living thing
Organ systems and organs
Organ System- Multiple organs in the body that works as a collective.
