Module 10 : Connections Flashcards
(Connections)
What is the theory of evolution? How is it a unifying theme in biology?
- a theory that explains how random changes in genetic material and competition for scarce resource cause species to change gradually
- unity and diversity of life
(Connections)
What is biogeography? How is it a unifying theme in ecology?
- dealing with geographical distribution of animals and plants
- helps predict and explain distribution of species on Earth.
(Connections)
What is genetics? How is it a unifying theme in biology?
- scientific study of heredity
- DNA is the informational basis underlying all processes and structures of life
(Connections)
What is plate tectonics? How is it a unifying theme in earth science?
- the theory that pieces of Earth’s lithosphere are in constant motion, driven by convection currents in the mantle
- explains large scale dynamics of earth’s surface
(Connections)
What is the Big Bang Theory? How is it a unifying theme in astronomy?
- the theory that the universe originated 20 billion years ago from the cataclysmic explosion of a small mass of matter at extremely high density and temperature
- it accounts for the beginnings of both space and time
(Connections)
How do discoveries and advancements in one field of science have the ability to impact other fields of science? Give examples of this happening.
- forensic science technology solving problems, DNA
- medicine
(Connections)
How do discoveries and advancements in science have the ability to impact areas outside of science? Give examples of this happening.
- Science has played an important role in the development of many environmental, medical, and health-related laws
- help predict environmental effects of different actions
- identify ways to protect and preserve the environment
- can help learn about the past
- artistic fields : Art conservation and restoration rely heavily on chemistry and other science disciplines and uncover frauds
(Connections) How are the following branches of science integrated, connected, and related? (A) chemistry and biology (B) physics and chemistry (C) physics and astronomy (D) earth science and physics (E) earth science and chemistry
(A) chemistry and biology :
- any living thing has a chemical makeup, so the study if living things involves studying its chemistry
(B) physics and chemistry :
- one explains why an object has certain properties and the other explains how the objects move and use those properties; one is the world at a distance and the other is the world close up; you cannot have one without the other
(C) physics and astronomy :
- physics grew from the study of our natural world in astronomy, these two reunite to uncover origins of the universe and its evolution
(D) earth science and physics :
- geology looks to physics to model the earths currents and magnetic field
(E) earth science and chemistry :
- earth science depends on chemistry to determine what the earth is made of
Quiz A
What is an example of science’s impact on another discipline?
- Legal cases are more easily solved based on DNA evidence.
- Advances in DNA analysis and technology have led to improvements in legal and criminal justice fields.
Quiz A
How does earth science relate to chemistry?
- Chemistry’s periodic table of elements is crucial in understanding Earth’s structure, especially when studying rocks and minerals.
- The properties of different elements determine their ability to form various rocks and minerals.
Quiz A
How does chemistry relate to biology?
- Chemistry is involved in molecular reactions in living organisms.
- Molecular reactions in cells and in living organisms provides an example of a strong connection between chemistry (the study of molecules, molecular interactions, compounds, and reactions) and biology (the study of life; the study of living things).
Quiz A
How is the Big Bang theory a unifying theme is astronomy/space science?
- It accounts for the on-going expansion of our universe.
- The Big Bang theory accounts for the ongoing expansion of the universe, and accounts for the beginning of both time and space in the universe. The Big Bang theory states that our universe began in a primordial explosion, known as the Big Bang, around 13.7 billion years ago and has been expanding ever since. Some evidence for Big Bang includes : the slowing of galaxies as they recede/expand, element abundance in the universe, and also the long wavelength radiation that permeates the universe.
Quiz A
How is evolution a unifying theme in biology/life science?
- It accounts for the adaptations of populations to the environment over time.
- Evolution accounts for the adaptations of populations to the environment over time, and a key driving mechanism in evolution is the process of natural selection.
Quiz B
What illustrates how science has impacted another discipline?
- Research on the environment, habitat, climate change, and endangered species have led to implementation of policies that impact other areas such as business, commerce, politics, and foreign relations.
- Research of ecosystems and the environment has led to policies such as the clean air act and endangered species act and other global conservation programs.
Quiz B
How does earth science relate to physics?
- Convection cells transfer heat from the core to the crust, contributing to the lateral movement of tectonic plates.
- Convection cells and convection currents help to drive the movement of the plates. These currents are driven by imbalanced forces within the mantle.
