Explanation:
Indeed, Al Khwarizmi (Muḥammad ibn Mūsā al-Khwārizmī) works on mathematics has impacted our understanding of mathematics today.
For example, Al Khwarizmi has been attributed as the founder of algebra, an interesting branch of mathematics. That is to say, if not for his works on algebra, we may not have had proper knowledge about solving equations (quadratic equations).
One of his interesting quote that reflects our modern understanding of mathematics is,
"When I consider what people generally want in calculating, I found that it always is a number. I also observed that every number is composed of units, and that any number may be divided into units. Moreover, I found that every number which may be expressed from one to ten, surpasses the preceding by one unit: afterwards the ten is doubled or tripled just as before the units were: thus arise twenty, thirty, etc. until a hundred: then the hundred is doubled and tripled in the same manner as the units and the tens, up to a thousand;… so forth to the utmost limit of numeration."
function of chlorophyll during photosynthesis
Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.
HELP!!!!!How do you think cell phones affect attention in class? Describe an experiment you could perform to test your hypothesis. Include your hypothesis, operational definitions of your independent and dependent variables, who your participants would be, and how you would randomly assign them to experimental or control groups.
Answer:
Students themselves realize that cell phones usage does not promote learning; in one survey, 80% of the students agreed that using a mobile phone in class decreased their ability to pay attention. In several surveys, students have reported that texting is distracting to nearby students.
Cell phone affects the attention and concentration in class as the student may not be able to understand what has been taught while using cell phone.
One experiment can be performed to understand whether cell phones affect the attention in class. Hypothesis: Cell phones negatively affects the attention in class. Independent variable can be defined as variable that can change in an experiment. Here, independent variable is the cell phone. Dependent variable can be defined as the outcome of the experiment which changes with the effect of independent variable. Here, dependent variable is attention in class which can be analyzed by observing the test scores after the lecture. Experimental group will include students who will sit in class along with cell phones during lectures and control group will include the group of students that will sit without cell phone in the class. Their attention can be analyzed by using test scores of test conducted after lecture. Students can be randomly assigned with experimental or control group turn by turn in one phase they will carry their cell phones in class and in other phase they will not be allowed to carry them. So, the exact effect on each trial can be learned.Hence, by above experimental procedure the effect of cell phones on attention in class can be understood.

What is citation?A citation serves as a pointer to a source. In order to acknowledge the importance of other people's works to the topic under discussion at the location where the citation appears, a citation is more specifically defined as an abbreviated alphanumeric phrase embedded in the body of an intellectual work that marks an entry in the bibliographic references part of the work.
What is typically thought of as a citation is, in general, the result of the union of the in-body citation and the bibliographic entry (whereas bibliographic entries by themselves are not).
Citations serve many crucial roles. Correct attribution of insights to earlier sources is simply one of these goals, despite the fact that their functions for ensuring intellectual honesty and supporting claims are often prioritized in training materials and style guides.

1. In what direction does the Earth rotate?
Answer:
1. Earth is rotating from West to East.
2. Maybe 365 days...
3. The Earth orbits the sun once every 365 days and rotates about its axis once every 24 hours. Day and night are due to the Earth rotating on its axis, not its orbiting around the sun. The term 'one day' is determined by the time the Earth takes to rotate once on its axis and includes both day time and night time.
4. One side of the Earth faces the sun, while the other side faces away into space. The side facing the sun is bathed in light and heat—we call this daytime. ... Because the Earth is constantly spinning, the line between day and night is always moving around the planet.
5.The Earth's axis runs from the North Pole to the South Pole. It takes the Earth 24 hours, or one day, to make one complete rotation around this invisible line. As the Earth rotates, each area of its surface gets a turn to face and be warmed by the sun. This is important to all life on Earth.
