4.The role of an enzyme in a chemical reaction is to change which of the following?
A. the type of rection
B. the activation energy of the reaction
C. the pH at which the reaction occur
D. the temperature at which the reaction occurs
C. the data collected when a hypothesis is tested can support a theory.
Explanation:In scientific method theory and hypothesis are two major components. A hypothesis is either a suggestion for an observable phenomenon, or a prediction of a possible relation among different phenomena. Whereas a theory is a tested, well-substantiated, unifying explanation for a set of verified, proven factors. So we can say that the data collected when a hypothesis is tested can support a theory.
Answer to Q2
B. released
Explanation:The word Exo means out or released therefore exorgonic reactions are those reactions in which energy is released. The same reaction which allows energy release is called exothermic reaction and the energy is in the form of heat.
Answer to Q3.
A. carbon dioxide + water ->glucose + oxygen
Explanation:Photosynethesis is the process in which plants make their food in the presence of sunlight. A simple word equation that can be used to describe the process of photosynthesis is carbon dioxide + water —> glucose + oxygen + water. A balanced chemical equation for the process can be written as 6CO2 + 6H2O —> C6H12O6 + 6O2. Overall, photosynthesis uses light energy to convert carbon dioxide into a carbohydrate.
Answer to Q4.
B. the activation energy of the reaction
Explanation:Enzymes are just like catalysts in an y chemical reaction. We know that catalysts are the chemicals which speeds up the reactions. In the same way enzyme speeds up the reaction and they increase the activation energy of any chemical reaction.

What is the common name of this gas, N2, the most prevalent in our atmosphere? A) sodium B) nickel C) nitrogen D) oxygen
Answer: The correct option is C) Nitrogen.
Nitrogen ( N₂) is the most prevalent gas in the atmosphere. It contributes 80% in the atmosphere. It is a highly stable gas because it contains three bonds between the two nitrogen atoms. So, it requires high energy to break these chemical bonds.
Nitrogen is the basic nutrient for the survival of all life forms. It is present in bio-molecules like proteins and DNA.
Nitrogen gas can not be used as such by the plants and animals. Therefore, it is converted into other forms so that plants and animals can utilize it. The process of conversion of N₂ into other biologically available form is termed as Nitrogen fixation.

Give two ways that the model is like a person and two ways the model is not like a person.
It's a plastic model of a human, cut open to see body functions.
A plastic human body model replicates human anatomy visually but lacks biological functionality such as movement and physiological processes like digestion.
Explanation:A plastic model of a human is like a real person in that it visually represents the human anatomy and can help us understand how our body functions -- for example, it can demonstrate the layout of the human skeletal system or show the organ placement inside the body. However, it is not like a person in that it lacks the ability to move, react, or process biological functions that a living human would. The model does not possess a biological system at work and it cannot replicate physiological processes such as digestion, respiration, or circulation.

Maya believes inchworms are faster than snails.she conducts an experiment to test her hypothesis which of the following would show her confirmation bias?
A-maya disproves her hypothesis
B-maya proves her hypothesis
C-maya ignores the inchworms which are slower than snails
D-maya focuses equally on all worms in the experiment
Answer: Option C
Explanation:
Maya believes that inchworms are faster when compared with snails. To prove this hypothesis she performs experiment and while performing experiment she ignored the inchworms that moves slower than snails.
This is a biased condition because she ignored the inchworms that were slow.
If she would have been unbiased then she should have tested all the inchworms that were slow or fast from snails.
Hence, option C is the correct answer.

More photosynthesis causes pH levels to increase or decrease?
The leaves of a plant are dotted with openings known as stomata. When open, stomata allow the plant to exchange gases and allow moisture to evaporate, helping to draw water from the roots up into the plant. These activities help the plant to
maintain homeostasis
synthesize minerals
produce light energy
decompose organic matter
Answer:
The correct answer is "maintain homeostasis".
Explanation:
Homeostasis is a concept used in science to refer to the propensity to have a constant internal environment within an organism. The plants maintain its water homeostasis in the along the whole plant by the dotted opening in its leaves known as stomata. By allowing the exchange of gases through stomata, the plant regulate how much water is presented in the roots and in the plant's body, maintaining an internal environment within the whole organism.
What is the Sun's apparent path through the sky in the northern hemisphere
The Sun's apparent path through the sky in the northern hemisphere forms an arc that changes with the seasons, with longer, higher paths in summer and shorter, lower paths in winter, affecting daylight hours.
The Sun's apparent path through the sky in the northern hemisphere changes with the seasons due to Earth's 23.5° tilt on its axis and its orbit around the Sun. During summer in the northern hemisphere, the path is long, and the Sun rises north of east, culminating at a high point in the sky around noon before setting north of west, resulting in longer days. In contrast, during winter, the Sun takes a shorter path, rises south of east, and sets south of west, spending less time above the horizon and leading to shorter days. On equinoxes, approximately March 21 and September 21, the Sun rises directly east and sets directly west, spending equal amounts of time above and below the horizon.
At noon, the Sun reaches the highest point in its daily journey across the sky, crossing the north-south direction, usually to the south of the observer in the northern hemisphere. This height above the horizon at noon varies with the seasons, reaching its maximum during the summer solstice around June 21 and its minimum during the winter solstice around December 21.
How do algae, cyanobacteria, and plants produce their own food?
Algae, cyanobacteria and plants are autotrophs. They produce their own food by the process of photosynthesis.
The only living things with the ability to carry out photosynthesis are plants, algae, and a kind of bacteria known as cyanobacteria. Photoautotrophs are organisms that produce their own nourishment using light.
The only biological mechanism that turns sunlight, which is energy from space, into chemical energy in the form of G3P is photosynthesis, from which sugars and other molecules can be created.
In the process of photosynthesis, light-absorbing molecules in leaves energize electrons, which are subsequently stored in the covalent bonds of carbohydrates. When those covalent connections are broken during cell respiration, the energy contained inside them is released.
Therefore, the algae, cyanobacteria and plants prepare their food by photosynthesis.

Final answer:
Algae, cyanobacteria, and plants, collectively referred to as photoautotrophs, use photosynthesis to convert sunlight, carbon dioxide, and water into glucose, providing the base for most food chains.
Explanation:
Algae, cyanobacteria, and plants produce their food through a process called photosynthesis. They are known as photoautotrophs, organisms that use sunlight as an energy source to synthesize organic compounds from carbon dioxide and water.
During photosynthesis, they capture light energy using pigments like chlorophyll, which is contained within organelles called chloroplasts in plants and algae, and within specialized structures in cyanobacteria. This energy is then used to convert carbon dioxide and water into glucose, a simple sugar, and to release oxygen as a byproduct. These organisms provide the base for most food chains and are essential for life on Earth because they produce the organic compounds that other organisms, known as heterotrophs, depend on for energy.
