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.

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.

IN FIVE TO TEN SENTENCES, DISCUSS the major concepts of populations, and
how these concepts contribute to balance in the ecosystem.
Answer:
A small change in our ecosystem could forever impact the whole web. For example, if bees were to go extinct, then flowers wouldn't be able to reproduce (since bees fertilize the flowers). Meaning the flowers would die out. And a lot of living things, including humans, depend on bees. Or let's say that a sharks were to go extinct. They play a major role in our ecosystem, because they eat fish and other sea creatures. The prey would then grow in population. Which would lead to a disaster. So in short terms, every creature in the ecosystem is vital to maintain the balance. I hope this helps!! :)

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.

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.

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.
