Answer:
The formula for photosynthesis: CO2 + H2O → C6H12O6 + O2, provides evidence for the law of conservation of mass and energy, which states that mass and energy cannot be created or destroyed, only transformed from one form to another.
In photosynthesis, carbon dioxide and water are transformed into glucose (C6H12O6) and oxygen gas (O2) through the process of absorbing light energy. The number of atoms of each element on the reactant side of the equation must equal the number of atoms of each element on the product side of the equation in order for the equation to be balanced and thus satisfy the law of conservation of mass.
This means that the total mass of the reactants (CO2 + H2O) must equal the total mass of the products (C6H12O6 + O2), and none of the mass can be lost or gained in the process. This satisfies the law of conservation of mass.
Similarly, the energy required for photosynthesis comes from the absorbed light energy, which is transformed into chemical energy stored in the glucose molecule. The energy of the reactants (CO2 and H2O) must be equal to the energy of the products (C6H12O6 and O2), again satisfying the law of energy conservation.
Therefore, the formula for photosynthesis provides evidence for the law of conservation of mass and energy, as it demonstrates that mass and energy are conserved and transformed in a predictable way during the process of photosynthesis.
Explanation:
The chemical formula for the equilibrium reaction of photosynthesis is 6CO2+6H2OC6H12O6+6O2.
How can you demonstrate that CO2 is required for photosynthesis?Iodine solution should be applied to the leaves. The plant's leaves in the jar without the KOH solution change colour from green to blue-black as a result of the starch in the leaves reacting with the iodine. Yet, because the plant cannot manufacture starch in the absence of carbon dioxide, the leaves of the plant in the KOH-filled jar do not change colour.
How do photosynthesis and cellular respiration relate to the equation CO2 h2o C6H12O6 O2?Glucose is produced during photosynthesis from sunlight, six carbon dioxide molecules, and six water molecules (C6H12O6). Glucose (C6H12O6), six water molecules, and six oxygen molecules are used in cellular respiration to produce six carbon dioxide molecules, six water molecules, and six oxygen molecules.

We eat the _____ and breathe in the _____ made by plants
They exhale carbon dioxide while consuming oxygen. They act in the contrary, says Maggy Benson. They exhale one gas and inhale another at the same time, once during the day, and the reverse during the night.
What is the source of animal and plant respiration?Simply said, whereas humans breathe in oxygen and exhale carbon dioxide, plants do the opposite. Since we breathe via our mouths. Furthermore, plants have mouths. Stomata, which is Greek for "mouths," are little structures that cover the green sections of land plants. The stomata, like in photosynthesis, allow plants to absorb oxygen from the atmosphere. "Aerobic respiration" is the process of breathing while there is oxygen present in the cell's mitochondria. The two types of respiration that occur in plants are light and dark respiration. They can use solar energy to create their food once they have carbon dioxide and water. An additional gas called oxygen is a byproduct of producing plant food.To learn more about plants breathe, refer to:

Hypothesis: If the mystery food is tofu, then it will react with the reagent that indicates the presence of a protein because tofu is primarily protein.
Based on the data, was Zack, who ate the tofu, guilty of leaving a mess in the classroom?
Justify your answer.
If reagent turned purple, Zack ate tofu and was guilty of leaving a mess; otherwise, he was not guilty.
That's what the speculation expresses in the event that the secret food is tofu, it will respond with the reagent that demonstrates the presence of a protein. In light of the information, assuming that the reagent became purple subsequent to testing the secret food that Zack ate, then, at that point, it demonstrates the presence of a protein and supports the speculation that the secret food was tofu. In this manner, Zack would be at legitimate fault for leaving a wreck in the study hall on the off chance that the reagent became purple since he was the one in particular who ate tofu. Nonetheless, in the event that the reagent didn't become purple, it implies that the secret food was not tofu or didn't contain sufficient protein to be distinguished by the reagent. For this situation, Zack wouldn't be at legitimate fault for leaving a wreck in the homeroom. The end would rely upon the aftereffect of the examination and regardless of whether it upheld the speculation.

explain how overproduction and the carrying capacity of an environment lead to competition in simple terms
Answer:
Overproduction refers to a situation where a population of living organisms produces more offspring than the environment can support. Carrying capacity, on the other hand, refers to the maximum number of individuals that an environment can sustain over a certain period of time.
When the population of a species exceeds the carrying capacity of the environment, there is intense competition for the limited resources such as food, water, and shelter. This competition can occur between members of the same species (intraspecific competition) or between different species (interspecific competition).
As the competition for resources increases, some individuals may not be able to access enough resources to survive and reproduce, leading to a decline in their population. The individuals with advantageous traits that help them compete for resources will be more likely to survive and pass on their genes to the next generation.
Over time, this process of competition for resources can lead to changes in the population, such as adaptations and natural selection, that help individuals survive in the environment.
Explanation:
When there are too many animals living in an environment (overproduction) for the carrying capacity (the amount of individuals that can be supported in the environment long-term), there will not be enough resources like food, water, and shelter for everyone. This leads to competition for the limited amount of resources available.
Over time competition can lead to changes in the populations. The animals that are best adapted to the environment or are most efficient at obtaining resources will be more likely to survive and pass on their traits to their offspring. This can also lead to the evolution of a new species or adaptations within a species.
Why the bag changed its shape explain using water potential
The bag's size changed as a result of water moving inside the bag in reaction to the water potential.
What is the potential of water?The energy needed to move a tiny amount of water across a barrier is referred to as the water potential.
We must keep in mind that water potential causes the water to flow inside the bag, changing its form as depicted. In reaction to this potential, water started to migrate within the bag.
The likelihood that water in a solution may undergo osmosis reduces as a solution's solute concentration rises. As a result, a solution's osmotic (solute) potential becomes more negative the more solute is added to it.

what is Kw?
what is the [H3)+] in pure water?
Answer:
In chemistry, Kw is called the dissociation constant or ionization constant of water.
The concentration of H3O+ ions in pure water at 25°C is 10^-7 M . This means that there are 10^-7 M of H3O+ ions in pure water.
Explanation:
Kw is the ion product constant for water, which is the product of the concentrations of hydrogen ions (H+) and hydroxide ions (OH-) in water at a given temperature. At 25°C, Kw has a value of 1.0 x 10^-14. This means that for any aqueous solution at 25°C, the product of the concentrations of H+ and OH- will always equal 1.0 x 10^-14.
In pure water at 25°C, the concentration of H+ ions (also called hydronium ions or H3O+) is equal to the concentration of OH- ions. This is because pure water is neutral, meaning that it has an equal number of positive and negative ions. Therefore, the concentration of H3O+ in pure water at 25°C is also 1.0 x 10^-7 M.

10. Ice Ages come and go.
A. How do scientists think Earth's orbit relates to an Ice Age? (2 points)
B. What is precession? (1 point)
C. How is precession related to an Ice Age? (2 points)
Answer:
A. Scientists think that Earth's orbit can play a role in the onset of an ice age because it affects the amount of solar radiation that reaches different parts of the Earth's surface. Specifically, variations in Earth's orbit can lead to changes in the distribution of sunlight, which can influence the temperature and precipitation patterns that are necessary for the growth and retreat of glaciers.
B. Precession is a term used to describe the slow, cyclical wobbling of Earth's rotational axis. This wobbling causes the direction that the axis is pointing to slowly shift over time, completing one full cycle approximately every 26,000 years.
C. Precession is related to an ice age because it can affect the timing and intensity of the seasons, which in turn can influence the growth and retreat of glaciers. During certain phases of precession, the Earth is closer to the Sun during the summer in one hemisphere and farther away during the winter, which can lead to more extreme temperature and precipitation patterns. These patterns can create conditions that are more favorable for the growth of glaciers, which can contribute to the onset of an ice age.

Is bile an enzymes? Explain. How is bile an important in digestion.
No, bile is not an enzyme. It is a digestive juice produced by the liver and stored in the gallbladder. Bile is essential for digestion as it helps to break down fats into smaller molecules, which can be absorbed and utilized by the body.
Bile contains bile salts, which act as emulsifiers and help to break down fat globules into smaller droplets. This increases the surface area of the fats, making it easier for digestive enzymes, such as lipase, to act on them. Bile also helps to neutralize the acidic chyme (partially digested food) that enters the small intestine from the stomach, creating a more favorable pH environment for the digestive enzymes to work.
Apart from aiding in digestion, bile also helps in the excretion of waste products, such as bilirubin, cholesterol, and other toxins, from the body. This makes it an important component of the body's natural detoxification system.
In summary, while bile is not an enzyme itself, it plays a crucial role in the digestion and absorption of fats, as well as the elimination of waste products from the body.
Answer:
No, bile is not an enzyme. It is a greenish-yellow fluid that is produced by the liver and stored in the gallbladder. Although it does not contain enzymes, it plays an important role in digestion.
Bile helps to emulsify fats in the small intestine, which means it breaks down large fat globules into smaller droplets. This increases the surface area of the fat, which allows pancreatic enzymes called lipases to break down the fat more efficiently. Without bile, digestion and absorption of fat would be less efficient.
In addition to aiding in fat digestion, bile also helps to neutralize stomach acid that enters the small intestine, which is important for protecting the lining of the small intestine from damage. It also helps to eliminate waste products and toxins from the body, including excess cholesterol and bilirubin, a waste product from the breakdown of red blood cells.
Overall, bile is an important component of the digestive system, even though it is not an enzyme. It aids in the digestion and absorption of fats and helps to eliminate waste products from the body.

Draw and label a diagram to illustrate the principle of regulating arterioles through intrinsic vs extrinsic regulation
- Describe how chemical and physical changes determine COD (ex. metabolic changes that lead to active hyperemia, vasoactive mediators, temperature and myogenic stretch response )
Regulating Arterioles:
Arterioles are small blood vessels that regulate blood flow to different organs and tissues. They have the ability to constrict or dilate in response to changes in metabolic demand, blood pressure, and other factors. This regulation can occur through two mechanisms: intrinsic and extrinsic.What is the intrinsic vs extrinsic regulation about?Intrinsic regulation involves the arteriole itself responding to local changes in the surrounding tissue. The main factor controlling intrinsic regulation is the metabolic demand of the tissue. As tissues become more active and require more oxygen and nutrients, they release metabolic byproducts such as carbon dioxide, adenosine, and potassium ions.
Extrinsic regulation involves the nervous and endocrine systems controlling arteriolar diameter through the release of vasoactive mediators. These mediators can either cause vasoconstriction or vasodilation, depending on the physiological need. For example, the sympathetic nervous system releases norepinephrine to constrict arterioles in response to low blood pressure or stress.
Chemical and Physical Changes:
Chemical and physical changes can also determine the regulation of arterioles. In response to metabolic demand, tissues release metabolic byproducts that cause vasodilation. Vasoactive mediators such as nitric oxide and prostacyclin also promote vasodilation. Conversely, vasoconstriction can be caused by factors such as endothelin-1 and thromboxane A2.Therefore, the Physical factors such as temperature and myogenic stretch response can also affect arteriolar diameter. Cold temperatures cause vasoconstriction, while warm temperatures cause vasodilation. Myogenic stretch response is the ability of arterioles to respond to changes in blood pressure by constricting or dilating to maintain a constant flow. When blood pressure increases, the arteriole constricts to prevent an excessive flow, and when blood pressure decreases, the arteriole dilates to maintain flow.
