The scientific method is a research method that consists of systematic observations, measures, experimentation, analysis, and verification of a hypothesis. It is based on reproducibility and refutability.
When conducting an experiment, you need to consider,
Definition and problem statement. The question for which there is not an answer yet. A question the investigator wants to answer.Theoretical framework. Antecedents from other investigations. Previous knowledge about the study object is always required for a better understanding.The main goal of the study is basically what the investigator wants to find out.Hypothesis formulation. The researcher makes a hypothesis to predict or make a conjecture -not verified and which requires corroboration- about what is going on or expected to happen. Identification of the study groups, and involved variables -independent, dependent, and control-.Methodology description. Steps needed to get data.Results. It includes data collection and analysis. This step involves testing the observations.Discussion and Conclusion, through which the hypothesis might be rejected or accepted.According to this framework, we can answer the question
1. Make an observation
d. The plants in my kitchen aren’t growing.
2. State the problem
a. Why aren’t the plants in my kitchen growing?
3. Identify variables
f. The amount of water my plants are getting and how much the plants grow.
4. Create a hypothesis
e. Will the amount of water I give my plants affect their growth?
5. Design an experiment
b. I will use three of the same type of plants. I will give plant A no water for one month. I will give Plant B five ounces of water daily for one month. I will give Plant C two ounces of water daily for one month. All plants will have access to direct sunlight for 6 hours a day.
6. Collect Data
g. After one month I see that Plant A did not grow and its leaves are brown. Plant B’s stem has grown by 4 inches and its leaves are large and green. Plant C has grown by 1 inch and has small green leaves.
7. Draw a conclusion
c. When I water my plants with five ounces of water daily, they will grow and maintain large, healthy leaves.

What is the main function of occipital lobe?The occipital lobes are located at the back of the head and are in charge of visual perception, which includes color, form, and motion.Injury to the occipital lobes can cause vision problems such as blindness or blind spots, as well as visual distortions and inattention. The occipital lobes are also linked to a variety of behaviors and functions, such as visual recognition, visual attention, and spatial analysis.The occipital lobe is primarily in charge of interpreting the visual world around the body, such as an object's shape, color, and location. It then relays this information to other parts of the brain, which interpret the visual information.To learn more about : Occipital lobes

Ciara believes that whenever
the Moon is in the position that
is shown from above (top view)
in Diagram A, the Moon always
looks completely dark in the
view from Earth, as shown in
Diagram B.
Is Ciara correct? If she is
correct, explain why the Moon
always looks dark from Earth in
that position, and explain how
she should show light in
Diagram A. If she is incorrect,
explain how else the Moon can
look when it is in that position.
Given the diagrams attached in the question, we can conclude that Ciara is correct in her prediction of the lunar cycle.
Ciara is correct in her prediction given that if the moon should be in this position, on the far side of the earth in relation to the sun, it would appear, when viewed from earth, to be completely dark. The reason behind this is that the moon does not have an internal light source. What this means is that the moon, much like the earth and unlike the sun, cannot generate light on its own.
Therefore, the light that we see when looking at the moon from the Earth is actually just reflected sunlight bouncing off the surface of the moon. The diagram shows that the moon is on the far side of the Earth in relation to the sun, meaning that in this case, the Earth would block most if not all of the light from reaching the moon, giving it a dark appearance.

Overpopulation of an animal species can be detrimental to the ecosystem.
ОА.
True
OB.
False
Answer:
True
Explanation:
Answer:
True
Explanation:
Wandering. When overpopulated animals are starving, their innate survival instincts cause them to wander into unnatural places in search of food. In many cases, overpopulated animals will wander into areas populated by humans. The outcome is animals killed on the highway, property damage and human injury.

How is bohr's atomic model different from rutherfords model
Answer:
Rutherford described the atom as consisting of a tiny positive mass surrounded by a cloud of negative electrons. Bohr thought that electrons orbited the nucleus in quantised orbits.
Explanation:
Bohr built upon Rutherford's model of the atom. In Rutherford's model most of the atom's mass is concentrated into the centre (what we now call the nucleus) and electrons surround the positive mass in something like a cloud.
Bohr's most significant contribution was the quantisation of the model. He believed that electrons moved around the nucleus in circular orbits with quantised potential and kinetic energies. So it was not possible for electrons to occupy just any energy level.

Cellular respiration occurs in a sequential order, this allows the cell to extract the energy it needs from glucose.
Cells need a constant supply of energy to preserve the biological order that keeps them alive, this energy comes from chemical bonds in food molecules, which are fuel for cells.
Cellular respiration is one of the most important processes that occur within living cells, it is constituted by a series of oxide reduction reactions, which allow obtaining energy through the degradation of an organic substance, glucose.
The cells that make up the body take advantage of the energy of chemical bonds, contained in glucose, when the molecule is degraded and oxidized to carbon dioxide (CO2) and H2O.
This energy is stored in the form of high-energy bonds (covalent bonds that release large amounts of energy when hydrolyzed) in ATP and NADPH molecules.
In turn, these carrier molecules are like portable sources of the chemical groups and electrons necessary for biosynthesis.
Therefore, we can conclude that cellular respiration occurs in a sequential order, this allows the cell to extract the energy it needs from glucose.
