Why do you think we see phases of the Moon?
Answer:
Just like the Earth, half of the Moon is lit by the Sun while the other half is in darkness. The phases we see result from the angle the Moon makes with the Sun as viewed from Earth. ... We only see the Moon because sunlight reflects back to us from its surface.

Some students wanted to find out the effects of giving vitamins to plants. They reasoned that since vitamins are good for humans, they should be good for other livings things, as well. Their hypothesis was "If plants are given water that contains vitamins, then they will grow taller". 1-What is the independent variable in this experiment?
Answer:
water containing vitamins
Explanation:
The independent variable is the variable that can be changed or manipulated in order to influence the dependent variable to get the outcome. The dependent variable is the variable that gets influenced by the independent variable.
In the given example, water containing vitamins are the independent variable that can be changed or manipulated that influence the growth of plant that is the dependent variable.

What kind of waves can travel through both matter and empty spcace
Answer:
An electromagnetic wave
Explanation:
An electromagnetic wave is a transverse wave that can travel across space as well as through matter. When it travels through space, it doesn't lose energy to a medium as a mechanical wave does.
Answer:
EM (electromagnetic) Waves
Explanation:
Light Waves (AKA EM waves) can travel through both matter and empty space. Light waves transmit energy by compressing the particles in mediums. Light waves can travel with and without mediums.
*light waves are the same as electromagnetic waves, they are the same thing*

explain how the equations for photosynthesis and cellular respiration compare.
Answer:
In Photosynthesis, carbon dioxide and water is yielded to glucose and oxygen. In respiration, glucose and oxygen is yielded to carbon dioxide and water. C6H12O6 (glucose) + O2(oxygen) → CO2(Carbon Dioxide) + H2O(water) + ATP energy.
Explanation:
The equations of photosynthesis and cellular respiration compare in such a way that one seems like the opposite of the other.
In photosynthesis, inorganic materials such as water and carbon dioxide are used to generate carbohydrates according to the following equation:
[tex]6CO_2 + 6H_2O + energy ---> C_6H_1_2O_6 + 6O_2[/tex]
In cellular respiration, carbohydrates are broken down to generate energy with water and carbon dioxide being by-products according to the equation below:
[tex]C_6H_1_2O_6 + 6O_2 ---> 6CO_2 + 6H_2O + energy[/tex]
Thus, the two processes are chemical opposite of each other. The starting materials of photosynthesis are the products of cellular respiration and vice versa.

When a flu virus enters the body, the immune system creates antibodies made of polypeptide chains to fight the virus. The specific shape of the protein allows it to bind to the virus and deactivate it. How does the antibody's primary protein structure create the specific shape to bind to flu viruses?
Answer and explanation:
Antibodies are structures made of four polypeptides, two light (L) chains and two heavy (H) chains that join together and form a molecule shaped like a "Y". This structure is possible thanks to the disulfide bonds that bind light chains and heavy chains together. While the stem of the Y is constant and doesn't change ("constant region"), the tips of the Y, composed of 110-130 amino acids and called "the variable region", vary greatly among the different antibodies and are responsible for the high specificity of these molecules.
This is why we could say that the primary structure of this protein is given by disulfide bridges that twist the antibody and allow it to bind to a protein from the flu virus.

You wan to study the effect of different types of water on the growth of plants you choose the same type of plants. All plants are planted in the same type soil, placed in the same location, exposed to the same room temperature. You water each plant with one of the four different types of water (salt water, regular water, sugar water and distilled water.) after a two-week period, the height of the plants is measured. What is the manipulated, responding, controlled variable
Answer:
The correct answer is -
The manipulated - type of water
Responding - the height of plants
Controlled variable- regular water
Explanation:
The manipulated or independent variable is in scientific research is a variable that is changed or manipulated to see the response of the responding variable or dependent variable.
In this case type of water, plants get, is manipulated as a different type of water is provided to different plants. So variable that is measured or showing response to the manipulated variable is, is responding variable that is the height of the plants.
The controlled variable is a variable that is set to see or compare the difference in normal condition and manipulated conditions that is regular water here in this case.

In an experiment, the variables that are kept the same between the experimental group and the control group are called ________.
A) Outliers
B) Constants
C) Dependent Variables
D) Independent Variables
Answer:
B. Constants
Explanation:
Constants are the factors that stay the same throughout the entire experiment no matter which group. The definition of a constant is "a situation or state of affairs that does not change." this furthers the point that constant is the correct answer because they don't change in the experiment.
B) I believe? Normally I'd say controlled variable
Different microscopic organisms cause different diseases. When a dangerous microscopic organism is transferred from one person to many people, the disease it carries will spread. Why is this considered a theory instead of a hypothesis or a law? It is a statement of fact about how nature works instead of an explanation. It provides an explanation for many observations and accepted hypotheses. It describes how to test a possible explanation of one specific relationship. It has not changed over time even though new technology has been developed.
Answer:
The correct answer is - it provides an explanation for many observations and accepted hypotheses.

1. Question: What effect does the amount of water have on plant growth?
Hypothesis:
If, then, because
Answer:
If a plant's soil has too much water, the roots can rot, and the plant can't get enough oxygen from the soil. If there is not enough water for a plant, the nutrients it needs cannot travel through the plant. A plant cannot grow if it doesn't have healthy roots, so the proper balance of water is key when growing plants
Explanation:
The hypothesis of this scientific question will state: IF the amount of water increases, THEN the plant growth will also increase.
WHAT IS HYPOTHESIS:
Hypothesis is a testable explanation of a phenomena. It is used in the scientific method to provide a possible answer to a scientific question. The hypothesis, which is subjected to testing via experimentation, shows the relationship between the independent variable (cause) and dependent variable (effect). The question of this experiment is as follows: 'What effect does the amount of water have on plant growth'. This means that the independent variable is the amount of water and the dependent variable is the measurable growth of plant.Therefore, the hypothesis will read as follows: IF the amount of water increases, THEN the plant growth will also increase.
