What is a heterotroph?
A heterotroph is an organism that cannot produce its own food and instead obtains its energy and nutrients by consuming other organisms. Which of the following is not a characteristic of life? A) Composed of cells B) Organized C) Ability to fly D) Responsive to environmental stimuli
C) Ability to fly Which of the following is not a characteristic of all living things? A) Composed of cells B) Ability to reproduce C) Ability to maintain homeostasis D) Ability to photosynthesize
D) Ability to photosynthesize What structure is common to all domains of living organisms?
Cells are common to all domains of living organisms. Which is a basic characteristic of all living cells?
All living cells are composed of cells, which are the smallest unit of life. Which of the following is not a property of life? A) Evolution B) Homeostasis C) Ability to reproduce D) Ability to teleport
D) Ability to teleport Which of the following best demonstrates the unity among all organisms? A) Presence of DNA B) Ability to fly C) Photosynthesis D) Ability to swim
A) Presence of DNA Which two of these characteristics does an organism with bilateral symmetry possess? A) Organized structure B) Ability to reproduce C) Ability to maintain homeostasis D) Ability to evolve
A) Organized structure and C) Ability to maintain homeostasis What are the simplest body structures considered alive?
Cells are the simplest body structures considered alive. Which function is not a property of life? A) Reproduction B) Homeostasis C) Evolution D) Ability to teleport
D) Ability to teleport What is the smallest entity that exhibits all the characteristics of life?
The cell is the smallest entity that exhibits all the characteristics of life. What is a characteristic that is not present in all living things? A) Composed of cells B) Ability to reproduce C) Ability to photosynthesize D) Ability to evolve
C) Ability to photosynthesize Which of these is an organism? A) Virus B) Bacterium C) Rock D) Water molecule
B) Bacterium What features are possessed by all complex multicellular organisms?
Complex multicellular organisms possess organized structures, composed of cells, and the ability to maintain homeostasis. Which of the following characteristics is shared by all living organisms? A) Ability to fly B) Composed of cells C) Ability to photosynthesize D) Ability to teleport
B) Composed of cells Which of the following is not one of the characteristics of life? A) Composed of cells B) Ability to reproduce C) Ability to maintain homeostasis D) Ability to teleport
D) Ability to teleport Which of these is not a characteristic of life? A) Composed of cells B) Ability to reproduce C) Ability to maintain homeostasis D) Ability to teleport
D) Ability to teleport Which of these is not needed by living organisms? A) Energy B) Water C) Ability to teleport D) Genetic information
C) Ability to teleport Which of these is not one of the basic characteristics of all living organisms? A) Composed of cells B) Ability to reproduce C) Ability to maintain homeostasis D) Ability to teleport
D) Ability to teleport Which of the following is not a characteristic of the genetic material? A) Composed of DNA B) Hereditary information C) Ability to teleport D) Passed down from generation to generation
C) Ability to teleport Which characteristic of living cells do viruses lack?
Viruses lack the ability to reproduce independently without hijacking other cells. What is true for all organisms? A) Composed of cells B) Ability to teleport C) Ability to photosynthesize D) Ability to fly
A) Composed of cells Which of the following need an outside source of organic nutrients? A) Autotrophs B) Heterotrophs C) Plants D) Algae
B) Heterotrophs What are some differences between plants and animals?
Plants are autotrophs that can photosynthesize, while animals are heterotrophs that consume organic material for energy. What are the eight key characteristics shared by all living organisms?
The eight key characteristics are: composed of cells, organized, responsive to environmental stimuli, maintain homeostasis, reproduce, acquire and utilize energy, contain genetic information (DNA), and evolve over time. How does organization benefit living organisms?
Organization allows living organisms to build complex structures from simpler ones, supporting survival and function. What is homeostasis and why is it important for living organisms?
Homeostasis is the maintenance of stable internal conditions, which is crucial for survival despite changing external environments. What is reproduction in the context of living organisms?
Reproduction is the ability to produce new individuals, either sexually (with two parents) or asexually (with one parent). What molecule contains the genetic information in all living organisms?
DNA contains the genetic information in all living organisms. Why are viruses generally not considered alive?
Viruses lack some characteristics of life, such as the ability to reproduce independently, so they are not considered alive. What is the role of DNA in living organisms?
DNA stores hereditary information that is passed from one generation to the next. What distinguishes living organisms from non-living things?
Living organisms display all eight characteristics of life, while non-living things do not. What does it mean for living organisms to be organized?
It means their structures are arranged in a specific, orderly way to support life functions. What is the difference between sexual and asexual reproduction?
Sexual reproduction involves two parents, while asexual reproduction involves only one parent.
