Which of these is NOT a characteristic of life?
Group of answer choices
oxygen usage
use of energy and metabolic processes
an organism consists of on or more cells
ability to reproduce
Oxygen usage is NOT a characteristic of life.
Cellular respiration is the metabolic pathway by which aerobic cells can produce energy by using the energy stored in the chemical bonds of foods in presence of oxygen.Conversely, there are organisms capable of fermenting foods in anaerobic conditions to produce energy in the form of ATP.Moreover, all organisms are composed of one or more cells and they carry out metabolic functions (i.e., reproduction, growth, differentiation, etc).In conclusion, oxygen usage is NOT a characteristic of life.

What is the main reason for using a data table collect data?
Answer:
Data tables help you keep information organized. If you're collecting data from an experiment or scientific research, saving it in a data table will make it easier to look up later. Data tables can also help you make graphs and other charts based on your information.
Explanation:
A scientist is unsure about the accuracy of her experiment. She has checked her equipment and found it to be in good working order, checked her data and found it to be accurate, and reviewed her interpretation of the data, which she found to be logical. What should she do in addition to check the accuracy of her results?
Answer:
The answer to the question above is given below
Explanation:
Since the scientist is unsure about the accuracy of her experiment, it could be possible the procedure she used was reliable but the result inaccurate or the procedure can also be inaccurate and also the result. She checked her equipment, data, and even the interpretation of the data and found all to be correct. But it wasn't mentioned if she repeated the experiment.
The following points will briefly highlight other possible ways to further check the accuracy of her results:
1. The accuracy of an experiment could also question how reliable it is. She should repeat the experiment over and over again without changing any parameter she used initially to test if she gets the same result. Similar results would imply an accurate experiment.
2. She should check if an experiment has been done before by another scientist on the same subject, check parameters used and compare values and results. This in other words is checking if the hypothesis is true.
3. She should check for random errors that could arise from environmental conditions that could influence her final result.

Laurie and Abby decide to make guacamole dip with chips to bring to a party. Laurie used a type of avocado called a Hass Avocado and Abby used a type of avocado called a Fuerte Avocado. Laurie and Abby both made their guacamole dip the same way except for one thing...Abby put lemon juice in hers to give it a 'tang.' When the girls uncovered their dip at the celebration, Laurie's had turned a brownish green but Abby's was still bright green. The girls wondered if adding the lemon juice to Abby's guacamole dip had helped it stay a nice bright green.
Hypothesis:
What is another variable that Laurie and Abby could test in this situation in a 2nd experiment?
Answer:
Lemon juice has 'chemicals' in it that make it citrus, and those same 'chemicals' preserve the guacamole. same thing as the 'life hack' where you rum lemon on cut apple slices and it makes them not brown.
