Of these things in an environment, which one is a living thing? Responses fungus (mushroom) fungus (mushroom) - not selected, this is the correct answer water (river) water (river) - incorrect soil (clay) soil (clay) - no response given air (wind) and explain how you would get that answer.
The living thing in this environment would be the fungus (mushroom). Fungi, including mushrooms, are living organisms that belong to their own distinct kingdom. They have cellular structures, obtain nutrients for energy, and can reproduce.
What made the discovery of cells possible?
Responses
the observation of cells by Hooke and Pasteur
the observation of cells by Hooke and Pasteur - no response given
the invention of the microscope
the invention of the microscope - not selected, this is the correct answer
the study of viruses and bacteria
the study of viruses and bacteria - incorrect
the use of magnifying glasses
the use of magnifying glasses - no response given
Score
explain how you would get the correct answer
To arrive at the correct answer, you need to consider the historical context and the tools available during the time of the discovery of cells. The study of cells became possible due to the invention of the microscope. Before the invention of the microscope, cells were not visible to the naked eye. The microscope allowed scientists like Robert Hooke and Louis Pasteur to observe and study cells, leading to the discovery and understanding of their structure and function. Therefore, the invention of the microscope made the discovery of cells possible.
Which of the following best describes cell theory?
Responses
cell theory describes the difference between multicellular and unicellular organisms.
cell theory describes the difference between multicellular and unicellular organisms. - no response given
cell theory describes the process of how cells come from preexisting cells.
cell theory describes the process of how cells come from preexisting cells. - no response given
cell theory describes the tiny structures that are found within cells.
cell theory describes the tiny structures that are found within cells. - incorrect
cell theory describes the three criteria for determining living things.
explain how you would get the correct answer
To determine the correct answer, you can consider the fundamental principles of cell theory. Cell theory is a scientific theory that describes the basic properties and functions of cells. It states that:
1. All living organisms are composed of one or more cells.
2. The cell is the basic unit of structure and organization in living things.
3. All cells arise from preexisting cells through cell division.
Based on these principles, the answer that best describes cell theory is: "cell theory describes the process of how cells come from preexisting cells." Cell theory does not specifically address the difference between multicellular and unicellular organisms, the tiny structures within cells, or the criteria for determining living things.
Amoebas are unicellular. The single cell splits in half to form two new cells. A student claims amoebas are alive. Is the student correct?
Responses
The student is correct; amoebas are probably alive because they have reproductive capabilities and create offspring through reproduction.
The student is correct; amoebas are probably alive because they have reproductive capabilities and create offspring through reproduction. - not selected, this is the correct answer
The student is correct; amoebas are alive because they become multicellular.
The student is correct; amoebas are alive because they become multicellular. - no response given
The student is not correct; amoebas are not alive because they are only made of one cell.
The student is not correct; amoebas are not alive because they are only made of one cell. - incorrect
The student is not correct; amoebas are not alive because two different amoebas are not contributing together to make a new offspring.
explain how you would get that as your correct answer
To determine the correct answer, we need to consider the criteria for determining whether something is alive. The characteristics of living organisms include the ability to reproduce, grow, respond to stimuli, and maintain homeostasis. In the given scenario, the student claims that amoebas are alive because they have reproductive capabilities and create offspring through cell division.
Amoebas, although composed of a single cell, do exhibit reproductive capabilities by undergoing a process called binary fission, where the single cell splits in half to form two new cells. This process effectively allows amoebas to create offspring.
Therefore, the student is correct. Amoebas are considered alive based on their reproductive capabilities, even though they are unicellular.
