Of these things in an environment, which one is a living thing?
What made the discovery of cells possible?
Which of the following best describes cell theory?
Amoebas are unicellular. The single cell splits in half to form two new cells. A student claims amoebas are alive. Is the student correct?
Of these things in an environment, a living thing would be the correct answer.
The discovery of cells was made possible by advancements in microscope technology, specifically the invention of the compound microscope in the late 16th century.
The best description of cell theory is that it states all living organisms are composed of cells, cells are the basic units of structure and function in living organisms, and all cells arise from pre-existing cells.
Yes, the student is correct. Amoebas are indeed alive as they are single-celled organisms capable of growth, reproduction, and responding to stimuli.
Of these things in an environment, which one is a living thing?
fungus
soil
water
air
Of the things listed, fungus would be considered a living thing. Soil, water, and air are all components of the environment but are not considered living organisms.
Which of the following best describes cell theory?
cell theory describes the difference between multicellular and unicellular organisms.
cell theory describes the process of how cells come from preexisting cells.
cell theory describes the tiny structures that are found within cells.
cell theory describes the three criteria for determining living things.
The best description of cell theory is that it describes the process of how cells come from preexisting cells. Cell theory states that all living organisms are composed of cells and that cells can only come from preexisting cells through cell division.
Use the additive inverse to find 8.76−26.54.
To find the additive inverse of a number, we change the sign from positive to negative, or from negative to positive.
The additive inverse of 8.76 is -8.76, and the additive inverse of 26.54 is -26.54.
Therefore, to find 8.76 - 26.54 using the additive inverse:
8.76 - 26.54 = 8.76 + (-26.54) = -17.78
Use the additive inverse to find −12 2/3−(−8 5/6). Write the answer as a mixed number.
To find the additive inverse of a number, we change the sign from positive to negative, or from negative to positive.
For the given expression: −12 2/3−(−8 5/6)
The additive inverse of −12 2/3 is 12 2/3, and the additive inverse of −8 5/6 is 8 5/6.
Therefore, −12 2/3−(−8 5/6) can be rewritten as 12 2/3 + 8 5/6.
Now, let's add the mixed numbers:
12 + 8 = 20
2/3 + 5/6 = (4/6) + (5/6) = 9/6 = 1 3/6 = 1 1/2
So, 12 2/3 + 8 5/6 equals 20 1/2 as a mixed number.
