How would holding your breath impact the cellular processes that are taking place in your muscles
Holding your breath has a variety of effects on the biological processes that occur in our muscles.
When you hold your breath, you're doing an anaerobic workout instead of an aerobic one.
Your muscles absorb oxygen from the atmosphere and burn it during aerobic exercise. Because your body can't accomplish that while you're anaerobic, your muscles produce lactic acid, which causes muscular soreness.

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.

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.
Hence, the correct answer is " water containing vitamins".

Students investigate how soil pH affects the height of tomato plants. Each of six tomato plants receives the same amount of
light each day and is planted in the same size pot and given the same amount of water. Each plant is planted in soil with a
different pH What is the dependent variable in the investigation?
Сь
Ос
Od
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.
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.

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.
Explanation:
The theory is well tested or substantiated explanation for the observation of the natural phenomenon, that included or incorporated various laws, hypothesis, or facts.
It is not just a possible explanation but a well-tested and proven explanation with the help of scientific experiments in a scientific method.
Thus, the correct answer is - it provides an explanation for many observations and accepted hypotheses.

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*
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.

In the given image labeling A is representing protein. The correct option is 2.
What is protein?Protein is an essential component of a healthy diet. Proteins are composed of chemical 'construction blocks' known as amino acids.
Amino acids are used by the body to build as well as repair muscles and bones, in addition to produce hormones and enzymes. They can also be employed as a source of energy.
Protein-rich foods involve meat, fish, livestock, eggs, lentils, and soy products such as tofu or soy products.
Individuals can also choose from this list of delicious high protein foods to ensure that individuals meet their requirements at each meal.

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.
