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

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.

The size of the pot in which the plants are grown
The pH of the soil in which the plants are grown
The amount of water given to the tomato plants
The height to which to tomato plants grow
Answer:
The height to which to tomato plants grow
Explanation:
In an experiment, the dependent variable is the variable that the experimenter measures. It is the variable that responds to changes made to the independent/manipulable variable.
According to this question, students investigate how soil pH affects the height of tomato plants. The different pH each plant receives is the independent variable while the HEIGHT OF THE PLANTS that responds to the soil pH or that is measured by the students is the DEPENDENT VARIABLE.

Explanation:
An enzyme is a protein that speeds up a chemical reaction. Enzymes are shape specific. The active site is a specific shape, which means it can only break down specific substrates.
Certain conditions can denature enzymes. For example, extreme temperatures or pH will cause the enzyme to deform and change shape, which means it cannot perform its job.
Therefore, the best choice is the second one: enzymes work best in specific conditions and only break down specific substrates.
How does a decrease/decline in a top predator impact biodiversity in an ecosystem?
Answer:
The most obvious result of the removal of the top predators in an ecosystem is a population explosion in the prey species. ... When prey becomes more scarce, the predator population declines until prey is again more abundant. Therefore, the two balance each other. When the predators are removed, prey populations explode.
how do you expect the period of a planet to change as its average distance from the sun increases?

What color is ragweed pollen
Answer:
A yellow-green.. Just search it up.
Explanation:
The color which can be attributed to the ragweed pollen when it is been analyzed can be regarded as greenish yellow.
How can the color of ragweed be described?Ragweed has tiny heads of greenish yellow blooms that produce large amounts of pollen that is dispersed by the wind rather than insects. While ragweed blooms are not particularly eye-catching, it is frequently simpler to identify these plants by their stems and leaves.
In the aster family, Asteraceae, the genus Ambrosia contains flowering plants known as ragweeds. They are found across the Americas' tropical and subtropical climates, particularly in North America, where the southwestern United States and northwest Mexico are the genus's origin and diversity core.

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.

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.

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.
