Test for Module 1 Flashcards
What is the difference between quantitative and qualitative data?
quantitative data involves numbers (counting or measuring); qualitative data is descriptive and doesn’t involve numbers.
photosynthesis
the process by which green plants and some other organisms use the energy of sunlight and simple chemicals to produce their own food
theory
a hypothesis that has been tested with a significant amount of data
homeostasis
the maintenance of stable internal conditions
A tiger develops lockjaw and can no longer open its mouth. What criteria for life will he not be able to perform?
It will not be able to eat so it will not be able to extract energy and maintain its metabolic processes, so its metabolism will be affected.
inference
logical interpretations based on prior knowledge, experience, or evidence
Organisms that experience mutations produce offspring with ___
marked differences as compared to the parents
anabolism
the sum total of all processes in an organism which use energy and simple chemical building blocks to produce large chemicals and structures necessary for life
Explain the difference between an observation and an inference
An observation is made using one of the 5 senses, i.e. describing something you see, hear, smell, touch, or taste. An inference is a logical interpretation based on prior knowledge or experience
Why did the law of spontaneous generation survive for so many years?
It survived because flawed experiments seemed to confirm it.
mutation
an abrupt and marked change in the DNA of an organism compared to that of its parents
Explain why it can be said that most of life on Earth gets its energy from the sun.
All life requires energy to power activities. Autotrophs can make their own food and they use the energy from the sun to do that. Heterotrophs will eat autotrophs or other heterotrophs that eat autotrophs to get the energy they need. So since all organisms either make their food using the energy from the sun or eat an organism that makes its own food, it can be said that all life on Earth ultimately gets its energy from the sun.
Organisms that make their own energy are called:
autotraphs
the detailed structures inside a muscle cell
transmission electron microscope
Heterotrophs
organisms that depend on other organisms for their food
