What are the characteristics of living things?️️Response to Surroundings, reproduction, growth and development, DNA, obtain and use energy, and cell organization What are the three parts of the cell theory?️️All living organisms are composed of cells, the cell is the basic unit of life, and cells arise from pre-existing cells. What are the levels of organization of living things?️️Organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, a...

Know the characteristics of prokaryotes vs. eukaryotes and the kingdoms that fall under each category.️️prokaryotic - (single-celled, 3.5byo, smaller, no nucleus/membrane-bound organelles, Archaebacteria & Eubacteria) eukaryotic - (mostly multicellular (except for some protists), 1.5byo, larger, have nucleus and membrane-bound organelles, Plants, Fungi, Protists, Animals) What is a change in gene frequency of a population over time due to natural selection?️️Evolution Evolution oc...

autotroph️️organism that can capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds; also called a producer biosphere️️part of Earth in which life exists including land, water, and air or atmosphere community️️assemblage of different populations that live together in a defined area consumer️️organism that relies on other organisms for its energy and food supply; also called a heterotroph ecology️️scientific study of interac...

biology️️the science of life cells️️basic unit of structure/function in all living things tissue️️groups of specialized cells species️️group of organisms that can breed and produce fertile offspring stimulus️️part of internal/external environment that causes a reaction in an organism homeostasis️️regulation of an organism's internal conditions to maintain life adaptation️️inherited characteristic resulting from changes to species over time science️️body o...

what is the workflow for histology (7)️️1) specimen collection 2) grossing 3) fixation 4) processing 5) embedding 6) microtomy 7) routine staining how are specimens received?️️they are removed from the body and sent to receiving area of the lab -in specimen container -if the specimen is sent fresh and no fixed they are in saline or saline gauze characteristics of a specimen container (5)️️-leak proof, screw cap lid -fixative or saline inside -wide mouth -WHMIS label -p...

Questions 1. What are the basic properties of life that biologists use to define living organisms? 2. Why is it challenging to come up with a precise definition of life? 3. How do unicellular and multicellular organisms differ in terms of their organization? 4. What is metabolism, and how is it categorized into anabolism and catabolism? 5. What does homeostasis mean, and why is it important for living organisms? 6. How do living organisms grow, and what role does cell division play in gro...

14.How does the concept of "organization" relate to the complexity of living organisms? 15.Why might some definitions of life include the ability to move, while others do not? 16.How do the processes of anabolism and catabolism contribute to an organism’s survival? 17.What are some examples of organisms that exhibit extreme adaptations for maintaining homeostasis? 18.How does cellular division contribute to the growth of multicellular organisms? 19.What are some examples of asexual ...
