Identify the following observation as qualitative or quantitative
The solution turned blue in color
Hey there! I'm happy to help!
Quantitative data are data that have to with quantities (numbers).
For example, how many inches tall is the plant, what is the pH level of this fluid, what is the temperature of the meat, etc.
Qualitative data are data that can be described or that have a specific quality (qualitative).
For example, are the flowers yellow or green, is the fluid bubbling, does the meat smell burnt, etc.
We see that a solution turning blue doesn't have to do with numbers, so it is not quantitative. It is qualitative because it has to do with the quality (in this case, color) of the solution and not a numerical statistic.
Have a wonderful day and keep on learning! :D

Jorge is studying a pond ecosystem in his neighborhood. The pond is home to a variety of plant and animal species, as well as a stop for birds that migrate through the region.
One summer, heavy rains wash an unusual amount of fertilizer into the pond. Jorge observes the algae population growing rapidly, and quickly algae cover the pond's surface. Several weeks later, many fish and other animals die in the pond. However, within two years, the algae population has returned to its previous size, as have the populations of all the ecosystem members.
Jorge's observations provide the strongest evidence for which of the following conclusions about the pond?
A. The pond ecosystem has very high biodiversity that protects it from invasive species.
B. The pond ecosystem is resilient to changes in many abiotic and biotic factors.
C. The pond ecosystem can withstand only certain levels of algal growth.
D. The pond ecosystem may change over time, but its species will continue living there indefinitely.
Answer:
I think that the answer is C.
Explanation:
If the levels of algae were too high then it would be the reason as to why the fish died. When the algae went back to normal,the fish were able to live there again.
I hope that helps!
Answer:
C.The pond ecosystem can withstand only certain levels of algal growth.

a. Its chemical properties change.
b. Its physical properties change.
c. The energy of its particles remains the same. hape
d. two of the above
Answer:
Matter either loses or absorbs energy when it changes from one state to another. For example, when matter changes from a liquid to a solid, it loses energy. The opposite happens when matter changes from a solid to a liquid. For a solid to change to a liquid, matter must absorb energy from its surroundings.
Answer:
d.
Explanation:
Its chemical and physical properties changes as a result of a change in temperature (increase or decrease in temperature).
Is the following sentence true or false? Scientific inquiry is a process with many paths, not a rigid sequence of steps.____________
Answer:
True
Explanation:
Scientific inquiry is a process with many paths, not a rigid sequence of steps. The given statement is true.
The scientific method isn’t as monolithic as it may seem in practice. Sometimes the results of an experiment suggest that a new approach is needed; sometimes, an experiment introduces whole new scientific questions into the picture.
Scientific inquiry goes beyond the development of process competencies such as observation, deduction, classification, forecasting, quantification, inquiry, interpretation, and analysis, all of which must occur simultaneously in order for scientific inquiry to occur.
So, the given statement is true.

How are energy in information used to keep an organisms body organized
Organisms use energy to survive, grow, respond to stimuli, reproduce, and for every type of biological process. The potential energy stored in molecules can be converted to chemical energy, which can ultimately be converted to kinetic energy, enabling an organism to move.
Explanation: I hope this helps! NOT MY WORK!
Energy is required for the cells to carry out their metabolic functions. Moreover, information (genetic information) is also fundamental to synthesize and regulate biomolecules required for the cells to carry out their functions.
All cells need energy to carry out their metabolic functions. i.e., to live, grow, and reproduce. Adenosine triphosphate (ATP) is the energy coin of the cell because this molecule provides releasable energy in the bonds between phosphate groups.For example, the energy released by the hydrolysis of ATP is used to synthesize biomolecules, endocytosis, exocytosis, cell motility, cell contraction, etc.The information stored in the sequence of the Deoxyribonucleic acid (DNA) molecule is used to synthesize structural and enzymatic proteins (as well as other cellular components) which are required to carry out cellular functions.Moreover, the information stored in DNA is also required to regulate the expression of genes involved in protein synthesis.In conclusion, energy and information (genetic information) are both fundamental to carry out cellular functions.

all chemical elements that are needed by living things are recycled in ecosystems true or false
Answer:
True
Explanation:
the answer is "True" / "T" hope this helps
Elements do not lose and gain energy as they move through ecosystems. Instead, they are continually recycled. Ecosystems recycle every chemical element required by living organisms, including carbon, nitrogen, hydrogen, oxygen, phosphorus, and sulfur. Therefore, it's true.
What is ecosystem?An ecosystem is a region where a bubble of life is created by plants, animals, and other organisms interacting with the weather, environment, and other factors. Abiotic variables, or nonliving components, coexist with biotic components in ecosystems. Plants, animals, and other species are biotic factors.

What is photosynthesis?
Photosynthesis can be defined as the process used by plants and other organisms to convert light energy into chemical energy that through cellular respiration can later be released to fuel the organism's activities. During photosynthesis in green plants light energy is captured and used to convert water, carbon dioxide and minerals into oxygen and energy rich organic compounds.
Therefore during photosynthesizing requirements needed include Sunlight, water and oxygen where two processes occur one light dependent and another which is light independent.

What kind of life forms were found in the blood falls and what kind of environment did they thrive in?
Answer:
Most autotrophs—organisms able to produce their own energy—are photosynthetic: They require sunlight and oxygen. The extremophiles of Blood Falls, however, do not use photosynthesis. They use a more unusual process called chemosynthesis. Chemosynthetic organisms are able to convert sulfur and iron compounds (not sunlight and oxygen) into energy. As Blood Falls’ chemosynthetic bacteria extract iron from the rocks they come in contact with, they gradually erode the bedrock around the lake.

Vital centers for the control of heart rate, respiration, and blood pressure are located in the ________. Group of answer choices medulla oblongata cerebrum pons midbrain
Answer:
cerebrum
Explanation:
it connects the brain to the spinal cord and control breathing and blood pressure
The vital center that is responsible for the control of the heart rate, respiratory rate, and blood pressure is located in the midbrain. The medulla is a part of the brains stem that is conned by the spinal cord.
Medulla oblongata being located at the base of the brain stem plays an essential role in incasing the messages from the spinal cord to the brain. It is essential for regulating the cardiovascular and respiratory systems.Hence the option A is correct.
