A. The power he used to move the boxes can be found by determining the rate at which work was done on the boxes.
B. The power Chad used to move the boxes is the force he used times the distance he moved them.
C. The power of the light Chad turned on is the amount of energy changed from electricity to light.
D. The power of the light Chad turned on is the amount of energy transferred per time.
2)Raul dug a hole in his yard to repair a water pipe. It took him 2 seconds to apply a force of 50 Newtons to push the shovel 0.25 m into the ground. How much power was used?
A. 0.01 watts
B. 6.25 J/s
C. 25.00 N•m•s
D. 100.00 watts
Answer:
1.) A and D
2.) B
Explanation:
The power he used to move the boxes can be found by determining the rate at which work was done on the boxes. The power of light Chad turned on is the amount of energy transferred per time. So the correct options are A and D. In 2nd, the power used was 6.25 J/s. So the correct option is B.
What is power?
The watt, denoted by the letter W, is the common unit used to measure power. James Watt, a Scottish businessman and inventor, is honoured with the unit's name. The watt is certainly a term you frequently encounter in daily life. Electrical devices like light bulbs and stereos commonly advertise their power output in watts. One watt is equivalent to one joule of work performed each second by definition.
Horsepower is another power unit that is still extensively used. This was first used to describe the ability of a regular horse to spin a capstan in the 17th century and is often represented by the sign hp. Since then, a metric horsepower has been defined as the force needed to raise a 75 kg mass a metre in one second, where 75 kg is the mass's weight in kilogrammes.
Therefore, for 1) the correct option is A and D and for 2) the correct option is B.

c) Assume that the concentration of the solute molecules varies over time on both sides of the membrane and that the solute molecules continue to pass through the membrane even when the concentration gradient is the reverse of the gradient shown. Describe the environment in and around the cell, as shown in the diagram, and the mechanism of transport of the solute molecules. (3 points)
Answer:
Does the movement of molecules stop when the concentration of a solute is equal on both sides of a membrane?
The concentration of solute molecules on both sides of the membrane will vary over time, and the solute molecules will continue to pass through the membrane even when the concentration gradient is reversed.
The environment in and around the cell is constantly. The diagram shows a cell with a higher concentration of solute molecules on the inside than on the outside. This means that there is a concentration gradient, and the solute molecules will tend to move from the inside of the cell to the outside. This process is called diffusion.
The solute molecules can also move through the membrane by other mechanisms, such as facilitated diffusion and active transport. Facilitated diffusion is a process that uses proteins in the membrane to help the solute molecules move across the membrane. Active transport is a process that requires energy to move the solute molecules across the membrane.
The concentration of solute molecules on both sides of the membrane will continue to change over time. As the solute molecules move from the inside of the cell to the outside, the concentration of solute molecules on the inside of the cell will decrease. This will create a new concentration gradient, and the solute molecules will continue to move from the inside of the cell to the outside.

Why is it important for cells of multicellular organisms to undergo mitosis? A) mitosis allows for reproduction B)mitosis increases variation within an organism. C) mitosis produces cells that are different from the original dividing cell. D)mitosis produces cells that are identical to the original diving cell
The answer is A mitosis allows for reproduction. This is because during mitosis two identical daughter cells are created which can contribute to an embryo.
Hope this helps ! <3
It is important for cells of multicellular organisms to undergo mitosis because mitosis produces cells that are identical to the original dividing cell. Thus, the right option would be D.
Mitosis involves the division of vegetative cells and it results in daughter cells with the same morphology and genome as the parent cell.
The division of vegetative cells in multicellular organisms will ensure that damaged or dead cells are replaced with cells of similar morphology and genome.
Apart from replacing dead or damaged cells, mitosis also allows multicellular to grow in size by allowing similar cells to spring from existing cells.

Answer:
The answer is a) enzymes
describe the active site of an enzyme. why is it important?
Answer:
An active site contains a binding site that binds the substrate and orients it for
catalysis. The orientation of the substrate and the close proximity between it and
the active site is so important that in some cases the enzyme can still function
properly even though all other parts are mutated and lose function.

Building Polymers
Monomers are the building blocks of larger molecules called polymers. A polymer consists of repeating monomers bonded to each other with covalent bonds.
Use the drawpad to connect each monomer to its polymer.
Answer: I'm doing the same homework. I'm pretty sure that the 6 hexagons are the startch glucose. Try page 2
Explanation:
Each monomer is correctly connected to its polymer in the attached image in which amino acid is attached with protein, the nucleotide is connected to DNA, the fatty acid is attached to fat or lipid, and glucose or sugar is attached to carbohydrates.
Monomers are the basic unit or building blocks of larger molecules known as polymers. Polymers are made up of two or more monomers or long chains of monomers attached together.
The macromolecules are polymers and made up of their particular monomers:
Proteins made up of amino acids: In the protein structure there are many amino acids are joined together with help of peptide bonds and due to this, it is also called a polypeptide chain.Nucleic acid (DNA) is made up of nucleotides- nucleotide monomers bind together and form chains of the nucleotides.Fat made up of fatty acids: Fats or lipids are polymers made up of long chains of fatty acids,carbohydrates made up of glucose monomers: glucose or other monosaccharides bind together to form polysaccharides or carbohydrates.Thus, the correct answer is attached as the image.

write a letter to your headmaster why moral lesson should be instill into students
Dear Mrs. Been.
In view of the importance that you have in our educational environment in relation to the position of headmaster that you occupy, I would like to emphasize the importance of classes with moral lessons, in the hope that you will authorize and encourage this type of lesson in our school.
The most important positive point of adopting this type of lesson is to teach students to distinguish correct and incorrect elements, about behaviors and concepts. This will allow for the formation of conscious adults with great rational capacity.
Another positive point is the ability to encourage students to solve ethical and moral problems that develop from a non-linear point of view, as most problems in the real world present themselves. By seeing and solving these problems in the school environment, students will be better prepared for the future that awaits them.
Last but not least, I would like to point out that students who have well-stimulated and trained moral concepts are better able to promote not only personal benefits, but also social, political and economic benefits for the communities in which they operate.
I look forward to your comments on this suggestion.
Kind regards,
Mary Lang
Dear Mr Peter,
Education is important to the growth and the development of the country and and since you play a vital role as a leader in this educational institution, I'll like to emphasize the importance of moral lessons to the students.
Moral lessons are important as they help in shaping the future of the students. When students are taught moral lessons, they will have good behaviors which will be vital to the nation.
Moral lessons can also enable the students know the difference between the rights and the wrongs on the society and enable them to be better citizens in the society.
Lastly, moral lessons can help in the promotion of peace and unity. When the students have good behaviors, they look out for each other and see always willing to help one another. This helps in promoting unity and peace in the school and the society at large.
In conclusion, I'll be glad if my letter is given a positive reply and moral lessons are instilled into the students.
Yours faithfully,
John.

Explanation:
the reason why it is called that because they mean the both thing but they are just diffirent wordsWhy does a pollutant end up multiplied as it travels up the food chain from producers to consumers?
Answer:
This is due to bio magnification.
Explanation:
When there is a gradual increase in concentration toxins(pesticides) in the tissues of organisms progressively in the food chain,the term for describing this is called -bio magnification.
The progressive multiplication in the concentration of these toxins may be due to non-biodegradable nature of the toxins,which are absorbed into the tissues of mostly the producers from the environment faster than they could metabolized by the body.
.Therefore these could not be removed by the producers, during excretion and respiration,and hence build up progressively upwards in the consumers.
A typical example is the phytoplankton which absorb toxins from sea water and accumulate this in the body.The build could not be ,metabolize by the body system,and is transferred to the zooplankton along the food chains when they feed on the phytoplanktons- this is Bio magnification.Chemical Structure of cellulose diagram
