C. the pH at which the reaction occur

D. the temperature at which the reaction occurs

Answers

Answer 1
Answer to Q1:  

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.

Early man removed salt from sea water by ____________.

Answers

Final answer:

Early man desalinated sea water primarily by boiling it off to extract salt, a process with historical evidence such as the Han-era deep drilling for salt brine. Other desalination methods throughout history have included freezing and reverse osmosis.

Explanation:

Early man removed salt from sea water by boiling off the water. This desalination process was essential for producing salt for food preservation and nutrition. Historical evidence, such as the Han-era practices, shows that ancient civilizations used techniques like deep drilling for salt brine and then boiling the water with natural gas to extract salt. This process can be likened to distillation, where the principle involves evaporating the water and then condensing it to leave behind impurities.

Moreover, desalination methods have evolved where various scientific principles have been applied. For instance, sea water can also be purified by freezing, a process where ice forms and leaves the salt and other impurities in the liquid water, or through reverse osmosis, which uses a semi-permeable membrane to separate salt from water.

when something accelerates then stops accelerating , what happens to the object?

Answers

The object continues to move in a straight line at the velocity it had when the acceleration stopped. Looking at Newton's laws of motion, you can see the acceleration and the subsequent motion covered by the 1st law. Newton's First Law: states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. * The first law here indicates that as long as there isn't an external force, the object continues to move in a straight line at an uniform velocity. This is the situation when there is no more acceleration (external force).

1. The graph below depicts the frequency of expression of the coloration of beetles on an island:

Graph is the 1st Pic

Birds are the main predators of these beetles; they hunt the beetles by sight and pick them up off of the tree bark where they feed. A logging company clears the trees off of the island and plants younger trees as a replacement. Trees with light bark are planted on one side of the island and trees with dark bark are planted on the other side of the island. What do you predict would happen to the range of coloration in the populations of beetles on each side of the island? Select TWO answers, one to represent the beetles living on the light colored trees and one to represent the beetles living on the dark colored trees. (2 points)

A. graph 2 below
B. graph 3 below
C. graph 4 below
D. graph 5 below

Answers

the correct answer is graph c

Graph 3  represent the beetles living on the light colored trees and graph 5 represent the beetles living on the dark colored trees.

Options B and D are correct

How do we explain?

These beetles are likely to experience selective pressure favoring lighter coloration because lighter-colored beetles would be better camouflaged against the light bark, making them less visible to birds. Over time, natural selection may lead to an increase in the frequency of lighter-colored beetles in this population.

In the same way, beetles on the dark-colored trees may experience selective pressure favoring darker coloration. Darker-colored beetles would be better camouflaged against the dark bark, providing them with a better chance of avoiding bird predation. Over time, natural selection may lead to an increase in the frequency of darker-colored beetles in this population.

What is the role of chlorophyll inside chloroplasts?

Answers

Chlorophyll molecules are contained inside chloroplasts, which are the food producers of the cell found in all green parts of a plant. ... This process, called photosynthesis, is how plants convert sunlight into usable chemical energy.

this would be your answer have an awesome day :)
Final answer:

Chlorophyll, the green pigment located in the thylakoid membranes of chloroplasts, is essential for photosynthesis as it absorbs sunlight and converts it into chemical energy used to produce plant sugars.

Explanation:

Chlorophyll is a vital green pigment found within the thylakoid membranes of chloroplasts, the organelle where photosynthesis occurs. It plays an essential role in the process of photosynthesis by absorbing sunlight and converting it into chemical energy. This energy is then used, along with water and carbon dioxide, to produce sugars for the plant, which are essential for its growth and development.

In chloroplasts, chlorophyll molecules are meticulously embedded in the thylakoid membranes, and when they capture light energy from the sun, they energize electrons within the chlorophyll molecule. These high-energy electrons are then used in a series of complex reactions to generate energy-rich compounds like ATP and NADPH, which subsequently fuel the Calvin cycle to synthesize sugars.

The presence of chlorophyll in plants also contributes to their green color, as it reflects green wavelengths of light while absorbing other wavelengths, particularly those in the blue and red spectrums, which are crucial for photosynthesis.

Which is the best example of a hypothesis?

When temperature increases, ice melts faster.
If temperature is increased, then ice will melt more quickly.
When ice melts quickly, it is because temperature was increased.
If ice melts quickly, then the temperature was increased.

Answers

A hypothesis is an "educated guess" or a question as others say, so I would say that your Third answer is the correct answer.

Final answer:

The best example of a hypothesis from the given options is 'If temperature is increased, then ice will melt more quickly.' This statement is testable and formatted correctly (If... then...), which aligns with the definition of a hypothesis in scientific inquiry.

Explanation:

To identify the best example of a hypothesis, it is important to understand what constitutes a hypothesis. A hypothesis is a suggested explanation that can be tested and is typically formatted as 'If... then...'. Therefore, the best example of a hypothesis from the options provided is, 'If temperature is increased, then ice will melt more quickly.' This statement sets up a condition (increased temperature) and predicts an outcome (ice melting more quickly) that can be tested through experimentation.

An example to illustrate the concept could be how you can dissolve sugar more rapidly in hot water, which demonstrates the principle that certain processes increase with temperature. To further explain, if a student approaches a warm classroom and asks why it is warm, proposing a hypothesis such as 'The classroom is warm because no one turned on the air conditioning' follows the correct structure. It is testable because the student can turn on the air conditioning to see if the classroom's temperature decreases.

two objects of the mass are on two different planets. planet a has force of gravity that is weaker than that of planet b. how will the weights of the objects compare to each other ?

Answers

The object will weigh less on planet a than b because the pull of gravity isn’t as strong

Explanation:

Weight is defined as the force that the gravity exerts on an object due to its mass. So higher the gravity higher the weight and lower the gravity lower the  weight. The object on planet 'a' that has a force of gravity that is weaker than that of the planet 'b' will have less weight than the object on planet 'b'.

Hope that helps :)

Answer:

The correct answer will be- tension

Explanation:

Centripetal force is the force acting on the object moving in a circular path with direction towards the center. The centripetal force causes the object to follow a curved path.

Three forces together act on the string with key: Tension (a force acting on the key chain due to string), gravity (the downward force), and friction (resisting force). Out of these the main source of action of centripetal force is the "tension" applied by the string on the key-chain.

Thus, tension is the answer.
