One student made the incomplete diagram shown below to represent the relationship between magma igneous rocks and metamorphic rocks.
Which of these is the correct next step to complete the diagram?
A. Put an arrow labeled cools and crystallizes pointing from igneous rocks to metamorphic rocks
B. Put an arrow labeled cools and crystallizes pointing for metamorphic rocks to igneous rocks
C. Put an arrow labeled heat and pressure points in from igneous rocks to metamorphic rocks
D. Put an arrow labeled heat and pressure pointing from metamorphic rocks to igneous rocks
Answers
Answer:
C. Put an arrow labeled heat and pressure pointing from igneous rocks to metamorphic rocks
Explanation:
Metamorphic rocks are changed rocks that are formed from pre-existing rocks that were once sedimentary or igneous rocks. Heat and pressure majorly act on igneous rock, which over time change these rocks into a different rock entirely, known as metamorphic rocks.
Therefore, the next step to complete the diagram will be:
"C. Put an arrow labeled heat and pressure pointing from igneous rocks to metamorphic rocks."

Why are coral reefs important to ocean life? Coral reefs take carbon dioxide out of the water and secrete it into their skeletons. Corals provide an important cleaning function by filtering debris from the water. Corals are an important link in the benthic food chain. Coral reefs provide food, shelter, and breeding grounds for thousands of marine organisms. Coral reefs grow upward to near sea level, providing shallow zones for benthic organisms.

an experiment is replicable if different scientist can do the experiment and get the same results true or false
Answers
Answer:
True
Explanation:
if multiple scientist do the same thing that means they are replicating the experiment
The statement "An experiment is replicable if a different scientist can do the experiment and get the same results" is definitely true.
What is a scientific experiment?A scientific experiment may be defined as a complete set of procedures that are carried out under controlled conditions in order to determine the validity and accuracy of a hypothesis or construct a discovery.
If multiple scientists construct the same hypothesis and perform identical research and received the same results. It implies that they are just replicating the same experiment number of times.
But the only difference is that they understand different things and methodology very closely based on such outcomes. This gives each scientist a sense of special perception based on facts and evidence.
Therefore, the statement "An experiment is replicable if a different scientist can do the experiment and get the same results" is definitely true.

Prior to the industrial revolution in the mid-1800s, a species of moth had light-colored wings speckled with small black spots. This coloration camouflaged the moths resting on the birch trees growing in their native habitat, since birch bark has similar coloring. In the early 1900s, this changed as dark soot produced by industrial pollution coated birch trees such that the trees lost their speckled coloring. Years later, it was observed that the moths of this species had changed from being light and speckled to being solid black. Which is the most plausible reason for this change
Answers
Answer:
The dark colored moths were due to a genetic mutation, and were more than likely present before the Industrial Revolution. Their fitness was low because predators could easily see them on the light-colored trees. They would be eaten before they could reproduce and pass on their genetic mutation. After the trees became darkened by soot, the darker colored moths now had the survival advantage, able to "hide" from predators. The lighter colored moths became more visible to predators, and the advantage shifted. Now, the light colored moths were more visible to predators, were eaten, and didn't have the chance to reproduce. The darker moths with the mutation had the survival advantage, blending in with the soot-covered trees, and were able to reproduce at higher rates, passing the mutation on to later generations.

When calcium carbonate is heated, it
decomposes into calcium oxide and carbon
dioxide. If 100 g of calcium carbonate are
decomposed, 56 g of calcium oxide is produced.
What would be the mass of the carbon dioxide
given off by the decomposition?
A. 448
B. 110 g
C. 156 g
Answers
Answer:
A. 44 g
Explanation:
First, you need to write a balanced equation:
CaCO₃ -> CaO + CO₂
Then, you need to find the molar mass of CaCO₃:
Ca = 40.078 amu
C = 12.0107 amu
3O = 47.9982 amu
_________________
100.0869 amu
Then, you calculate the moles of CaCO₃:
100 g ÷ 100.0869 amu = 0.9991 moles
In the balanced equation, we can see that the molar ratio of CaCO₃ and CO₂ is 1 : 1, so moles of CaCO₃ = moles of CO₂.
Now you need to find the molar mass of CO₂:
C = 12.0107 amu
2O = 31.9988 amu
________________
44.0095 amu
Finally, you can calculate the mass of CO₂ produced:
0.9991 moles * 44.0095 amu = 43.9698 g = 44 g

Answer:
The complete question with its options is:
Jenna's pencil fell off of her desk and she quickly reached down to catch it before it hit the ground. In the process, the (1)_____ system first recognized the falling pencil. It sent signals to the (2)______ system, which then moved the components of the(3) _____ system in order to catch the pencil.
Options:
(1) 1. Nervous 2. Muscular 3. Skeletal
(2) 1. Nervous 2. Muscular 3. Skeletal
(3) 1. Skeletal 2. Digestive 3. Nervous
The answer is:Jenna's pencil fell off of her desk and she quickly reached down to catch it before it hit the ground. In the process, the (1) Nervous system first recognized the falling pencil. It sent signals to the (2) Muscular system, which then moved the components of the(3) Skeletal system in order to catch the pencil.
Explanation:
The nervous system receives the signal that the pencil is falling. In other words, Jenna sees or feels that the pencil falls, so the senses send a signal to the nervous system to produce a response. We call this a stimuli. Once that the nervous system receives and processes the stimuli, it elaborates an answer. The answer is to send a signal to a group of muscles that will move certain bones to make the movement that will catch the pencil. The muscles are from the muscular system, and they are attached to the bones, which are part of the skeletal system. When the muscles contract, they move the bones and make the movement possible.

14. Brainstorm and write at least 3 potential challenges or important points to consider when conducting the described
data collection.
Answers
When conducting an experiment, there are different aspects to consider, such as the question that drives to the reseach, the hypothesis, theoretical framework, variables involved -independent, dependent, and controll-, methodology, study groups, data analisys, among others.
In the exposed example, Pincky is lacking theoretical framework, defining which are the study groups, methodology to collect data, and a description of data analysis.
---------------------
The scientific method is a research method that consists of systematic observations, measures, experimentation, analysis, and verification of a hypothesis. It is based on two aspects: reproducibility, which is the capability of reproducing the experiment in any other place by any researcher, and refutability, which is the susceptibility to be refused.
When conducting an experiment, you need to consider,
• Definition and problem statement. The question for which there is not an answer yet.
• Hypothesis formulation. A hypothesis is a scientific conjecture, not verified, that requires corroboration.
• Data collection and analysis. This step involves testing the observations.
• Results
• Verification of hypothesis. This step involves the deriving of the working hypothesis.
• Discussion and Conclusion.
Previous knowledge about the study object is always required for a better understandig. A question the investigator wants to answer. The main goal of the study, which is basically what the investigator wants to find out. The researcher makes a hypothesis to predict what is going to happen. The experiment is to be performed to answer the question. The conclusions through which the hypothesis might be rejected or accepted.
--------------
So in this experiment there must be,
Theoretical framework, such as information about the species, life stage at which they begin chirping, about external factors that might affect it or benefit it, and etcetera.
The goal: To know how temperature affects cricket´s chirping
Hypothesis: Crickets chirp less frequently under cold temperature than under warm temperature.
Variables: Temperature → Independent
Chirp frequency → Dependent
Water and food supply, light exposure, refuge → Controlled
Study groups: group of crickets exposed to a warmer temperature
group of crickets exposed to a colder temperature
Methodology: Individuals analyzed should be in the same development stage, or at least be sexually mature. Two groups of 10 individuals each should be placed under the same conditions, excepting for temperature. One of the groups should be exposed to warmer temperatures and the other one to lower temperatures. Chirps should be recorded for a week.
Data analysis: Using the chirps records, the frequency can be measured for each group. Results should be compared using different statistical analyses.
Results: Results should be clearly exposed, using texts, charts, and graphs.
Discussion and Conclusion: Hypothesis acceptance or rejection. Discussion about the expected results against the observed ones.

Explanation:
The natural vegetation and wildlife restoration is one of the main concerns that are essential for the development and growth of a country's biodiversity. Due to human land-use changes and migration of people, from one place to another with their cattle, lands are becoming deserted and grassland and forest land are declining.
So, we need to plant more trees that act as the natural habitat for the wildlife and preserve and conserve them in parks and sanctuaries which will help reduce the impacts of global warming and climate change. We should not kill any animal.We should decrease the use of plastics.
