Answer:
Please find the identified steps of the scientific method below
Explanation:
A scientific method is a series of steps that aims at solving a problem. The steps in a scientific method include:
1. Making observation: In this experiment, Maggie observed when she read that some plants grow better if the soil is acidic. This is her observation that led to the scientific question: Do plants grow better in an acidic soil?
2. Formulating hypothesis: Hypothesis is a testable explanation to a problem. In this experiment, Maggie's hypothesis is; IF acid is added to the soil, THEN plants will grow better
3. Test hypothesis: the hypothesis is tested by conducting an experiment. In this case, Maggie places two geranium plants of the same size in two pots. Then she added a tablespoon of vinegar to one of the pots and allows the other grow normally without acid. The independent variable in this experiment is the vinegar added while the dependent variable is the height of the plants. The plant group with the vinegar is the experimental group while the plant group without vinegar is the control group. The constants of this experiment are same sunlight, same amount of water, same location etc.
4. Analyse data: The growth of the control and experimental plants were measured every week for five weeks by measuring their heights. The height (cm) of the plants with vinegar for the five weeks as as follows: 10.0, 12.4, 14.8, 18.0, 21.4 while the height in cm for the plants without vinegar for the five weeks is as follows: 10.0, 11.5, 13.0, 15.7, 17.8.
5. Conclusion: Based on the result, the plants exposed to vinegar grew better each week except week 1, which is the week they started. Hence, the hypothesis of this experiment will be ACCEPTED because the experiment proves it.
The scientific method parts in the scenario are: observation, research question, hypothesis, experimental design, data collection, data analysis, and conclusion.
The following scientific method components are depicted in the scenario:
Maggie reads that certain plants thrive in acidic soil and expresses her scepticism about this assertion.
Will adding acid to the soil help plants develop more effectively? Maggie asks in her research question.
Maggie's hypothesis, even if it isn't stated in the scenario, can be deduced as follows: The plants will grow more effectively if acid is introduced to the soil.
Design of the Experiment: For Maggie's experiment, potting soil is used to fill two planting containers, and two geraniums of the same size are transplanted into each container. She makes sure that both containers have the equal amount of water, sunlight, and temperature.
Data collection: Over the course of five weeks, Maggie measured the development of the plants once a week, and she recorded the heights of each plant in a data table.
Data comparison and analysis are done by Maggie using the plants' measured heights during a five-week period.
Maggie can make inferences about her hypothesis and whether the vinegar addition had an impact on the plants' growth based on the information she has gathered and the analysis she has done.
Thus, these are the parts of the scientific method in it.

Threonine is a standard amino acid with a polar side chain.Identify the chiral centers in threonine. a. the carboxyl carbon b. the amino nitrogen c. carbon b d. carbon c e. carbon a
Answer:
Threonine has two chiral centers.
The correct options are c. carbon b and d. carbon c
Explanation:
Chiral centers are those that have four different groups of atoms bonded to it. Carbon a has three atoms of hydrogen attached to it so it can't be a chiral carbon. It isn't the carboxyl carbon either since it is double bonded to oxygen. And the amino nitrogen does not qualify anyway because it is bonded to three different groups of atoms, not four.

~Hope this helps Mate. If you need anything feel free to message me.
The eqation which reporesent Photosynthesis is 6CO2 + 6H2O ® C6H12O6 + 6O2
Photosynthesis is the process by which green plants manufacture their food(in form of sugar) using carbon dioxide and water in the presence of sunlight. This is possible because of the presence of chlorophyll which creates a medium to absorb the sun's energy. The Light energy formed then converts water and carbon dioxide into oxygen and sugars.
The chemical equation to represent the process is as follows
6CO2 + 6H2O ------> C6H12O6 + 6O2.
sunlight
Here, six molecules of carbon dioxide and six molecules of water reacts in the presence of light energy captured by chlorophyll from the sun to form sugar and six molecules of oxygen.

Nucleic Acids make up DNA. DNA, in turn, is used as a blueprint to make
Answer:
I believe its RNA
Explanation:
RNA is the new copy of DNA
Nucleic Acids make up DNA. DNA, in turn, is used as a blueprint to make RNA.
What is DNA?Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid.
The DNA of an individual can be found in almost all of their cells. DNA contains the bases adenine (A), cytosine (C), guanine (G), and thymine (T) (T).
All biological cells contain ribonucleic acid (RNA), a crucial biological macromolecule.
It plays a major role in the production of proteins by acting as a messenger for DNA, which in turn carries the genetic instructions necessary for life's growth and maintenance.
The DNA blueprint is first transcribed into RNA, another large macromolecule, to generate proteins.
To create proteins, ribosomes receive the exported RNA from the cell nucleus. The RNA sequence is read by ribosomes, which then use it as a template to make new protein molecules.
Thus, RNA is the molecule made from the blueprint of DNA.
