how the different biotic component interact among themselves?
Answer:
In general, abiotic factors like rock, soil, and water interact with biotic factors in the form of providing nutrients. Just as humans mine mountains and cultivate soil, rock and soil provide resources for plants, and plants cycle the nutrients through so they (usually) end up back in the ground where they began.
EARTH SCIENCE a student conducts an experiment to see how music affects plant growth the student obtains four identical plants each one is potted in the same type of soil and receives the same amount of sunlight and water each day plant a listens to classical music for three hours each day plant b listens to rock music for three hours each day plant c listens to country music for three hours each day plant d does not listen to any music at all. Based on the experiment in the scenario which visual aid would be most helpful in showing the change in the plants height over time? A. A pie chart B. A timeline C. A bar graph D. A line graph
Answer:
A time line would be my option
A line graph will be more helpful in showing the change in the plants height over time. The correct option is D.
What is a line graph?A line graph, also known as a line plot or a line chart, is a graph that connects individual data points with lines.
A line graph depicts quantitative values over a given time period. Line graphs are commonly used in finance to depict the historical price action of an asset or security.
Line graphs are used to chart changes over short and long time periods. Line graphs are preferable to bar graphs when there are minor changes.
Line graphs can also be used to compare changes in more than one group over the same time period.
A simple line graph is a graph that is made up of only one line.
Thus, the correct option is D.

Explanation:
Explain why mirages occur.
Answer:
Mirages happen when the ground is very hot and the air is cool. The hot ground warms a layer of air just above the ground. When the light moves through the cold air and into the layer of hot air it is refracted (bent). A layer of very warm air near the ground refracts the light from the sky nearly into a U-shaped bend.
Which step should you take before you begin a scientific investigation
Answer:
Before you begin to plan a scientific investigation you first a Perform background research to learn what is already known about the question you are trying to answer. You Create the data that will support your hypothesis.
Explanation:
Step 1: Record your observations.
These should be objective rather than subjective observations. In other words, the findings should be able to be independently verified by other scientists. Subjective observations based on personal views and opinions are not considered scientific. Here's an example of an objective statement: The temperature in this room is 58 degrees Fahrenheit. Here's an example of a subjective statement: This room has a pleasant temperature.
Making objective observations is the first stage in the Scientific Method. These assertions are based on specific events that have occurred and can be verified as true or incorrect by others.
Step 2: Come up with a hypothesis.
Our observations provide information about the past or present. We want to be able to forecast future events as scientists. As a result, we must rely on our reasoning abilities.
Scientists use historical data to establish a general principle or explanation that may be used to anticipate future events. A hypothesis is the term for the general principle. Inductive reasoning is the type of reasoning involved (deriving a generalization from specific details).
Step 3: Make an educated guess.
Step 2 resulted in a tentative hypothesis that may or may not be correct. How will we know whether our hypothesis is correct?
Our theory should be broad in scope and apply consistently over time and space. Scientists are rarely able to test every possible scenario in which a hypothesis could be valid. Consider the following hypothesis: A nucleus can be found in all plant cells. We can't test this idea by looking at every living plant and every plant that has ever lived. Instead, we use deductive reasoning to make a prediction. We can make the following prediction based on our hypothesis: Each cell in a blade of grass will contain a nucleus if I inspect it.
4. Carry out an experiment.
To gather information, we once again rely on our sensory sense. Based on our prediction, we devise an experiment.
The following is a possible scenario for our experiment: A total of 1000 patients aged 50 to 70 will be randomly allocated to one of two 500-person groups. The experimental group will receive Celebra four times daily, whereas the control group will receive a starch placebo four times daily. Patients will not be able to tell if their tablets are Celebra or placebo. The medications would be taken for two months by the patients. Medical exams will be performed at the end of the two-month period to see if the flexibility of the arms and fingers has changed.
Step 5. Analyze the results of the experiment.
The experiment produced the following results: 350 of the 500 people who took Celebra reported diminished arthritis as the end of the period. 65 of the 500 people who took the placebo reported improvement.
Step 6. Draw a conclusion.
From our analysis of the experiment, we have two possible outcomes: the results agree with the prediction or they disagree with the prediction. In our case, we can reject our prediction of no effect of Celebra. Because the prediction is wrong, we must also reject the hypothesis it was based on.
Step 7. Report your results.
Scientists publish their findings in scientific journals and books, in talks at national and international meetings and in seminars at colleges and universities. Disseminating results is an essential part of the scientific method. It allows other people to verify your results, develop new tests of your hypothesis or apply the knowledge you have gained to solve other problems.

Why does groundwater's level in the water table remain unchanged after use
Answer:
The level of the water table can naturally change over time due to changes in weather cycles and precipitation patterns, streamflow and geologic changes, and even human-induced changes, such as the increase in impervious surfaces, such as roads and paved areas, on the landscape.
What is the functional role of the t tubules?.
The transverse tubules (t-tubules) with regards to the cardiac muscles are invaginations of the surface membrane of cardiac ventricular myocytes
With regards to skeletal muscles, are located in the space between the two Sarcoplasmic reticulum (SR) cisternae.
In Skeletal muscles, they are tightly associated with the SR controlling the entry of action potentials into interior of muscle fiber. In cardiac muscles, these t-tubules which are rich in ion channels and are important determinant of cardiac cell function, that are important for excitation–contraction coupling, ensuring spatially synchronous Ca2+ release throughout the cell.Learn more about t-tubules: https://brainly.com/question/6763078

rna processing converts the rna transcript into _____.
Answer:
It converts RNA transcript into mRNA!
Explanation:
If you follow the steps of the Protein Synthesis, this will make sense (this is just a brief overview of it). So, you want to go from DNA --> RNA --> Protein. First, we start out with DNA that is inside the nucleus. From there, the DNA gets transcribed (transcription) into RNA (still in the nucleus). Next, the RNA gets spliced and synthesized into mRNA. mRNA gets exported from inside the nucleus to the outside of it through a nuclear pore and is now residing in the cytoplasm. Then, it gets translated (translation) into an amino acid chain. Finally, the a.a. chain will be synthesized into a protein.
