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.
hope this helps. :)

What is the role of a pioneer species in primary succession?
to destroy parasites
to provide shade
to provide fruit
to produce the soil
The role of a pioneer species is to produce the soil.
The role of pioneer species in primary succession is to produce the soil.
WHAT IS PRIMARY SUCCESSION?Primary succession is the type of succession in which there is no previous form of life in a habitat.
Pioneer species are those species that first colonize an area. In primary succession, pioneer species like lichen colonize bare rocks i.e. no soil.
Therefore, role of pioneer species in primary succession is to produce the soil.

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.

In a multicellular organism, the lungs are responsible for exchanging gases with the organism’s environment. Which cellular structure performs the same task for a cell?
Answer:
This question lacks options; the options are:
A) chloroplast
B) mitochondrion
C) endoplasmic reticulum
D) plasma membrane
The answer is B. mitochondrion
Explanation:
The Lungs of multicellular organisms, as described in this question, is a respiratory organ that is involved with the INTAKE of oxygen needed for cellular respiration and EXPULSION of carbon dioxide out of the body, a process called GAS EXCHANGE.
This gaseous exchange function of lungs is carried out for the process of respiration which is carried out at the cellular level by MITOCHONDRION. Mitochondrion is an organelle in eukaryotic cells associated with the cellular respiration (release of energy).
The gaseous reactants (oxygen) and products (carbon dioxide) of cellular respiration is exchanged by the LUNGS.
The cellular structure performs the same task for a cell
B. mitochondrion
Mitochondria:The Lungs of multicellular organisms, as defined on this question, is a breathing organ this is concerned with the INTAKE of oxygen wanted for cell breathing and EXPULSION of carbon dioxide out of the body, a manner referred to as GAS EXCHANGE. This gaseous change feature of lungs is finished for the manner of breathing that is finished on the cell degree via way of means of MITOCHONDRION. Mitochondrion is an organelle in eukaryotic cells related to the cell breathing (launch of energy). The gaseous reactants (oxygen) and products (carbon dioxide) of cell breathing is exchanged via way of means of the LUNGS.
Thus correct option is B.

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.

The source of a sound moves away from the listener. Listener has the impression that the source is ________ in pitch and the frequency has_______.
A.) lower. Increased
B.) lower, decreased
C.) higher, decreased
D.) higher, increased
Doppler Effect is defined as the change of frequency of a sound or light wave produced by a moving source and a stationary observer. The waves when they move towards the object compresses.
The correct answer is:
Option B. lower, decreased
The Doppler effect can be explained as:
1. The listener will have the impression that the moving source is higher in the pitch as it moves away from the listener.
2. The frequency of the waves will be decreased because the time between the successive sound waves is lengthened or increased.
Therefore, the pitch will be lowered and the frequency will be decreased.
