Epithelial Tissue

Epithelial Tissue It is composed of one or more layers of cells which cover the external and internal body surface. The cells lie closely connected with no intercellular spaces, on a thin gelatinous membrane and adhere to each other with considerable force. The free surface of the cells may be smooth or may have hair like cytoplasmic extensions such as cilia or microvilli. Blood vessels are absent in epithelial tissue. Functions: Protection of underlying tissues from injury, microbes and desiccation, Secretion of hormones and enzymes, Sense perception by sensory cells lining sense organs,Respiration,Absorption of digested food and removal of metabolic wastes. There are four types of epithelial tissues: 1. Squamous epithelium: They are compact, flat plate like cells with no intercellular spaces. They are seen on the lining of skin and cavities of ducts. Whenever it forms a lining as that of blood vessels, it is called by the special name endothelium. Functions: They protect underling parts from injury, entry of germs, chemicals and drying up. 2. Columnar epithelium: Cells are taller than broad with nucleus towards the base. Certain cells are adapted for secretion. They occur on the intestinal lining, sweat gland, tear gland, salivary gland and kidney tubules. Function: Gives mechanical strength, concerned with secretions. 3. Cuboidal epithelium: Cube likes cells which are square in section but the free surface appears hexagonal. They occur in kidney tubules, salivaryglands, and inner lining of the cheek. Functions: Give mechanical strength. 4. Ciliated epithelium: Cuboid or columnar cells with protoplasmic outgrowth called cilia. Occur in lining of trachea of vertebrates, kidney tubules and oviduct. Functions: Keeps out unwanted particles.

Listening to Music While Studying Can Help

Listening to Music While Studying Can Help Suzy S. Ah, the power of music!   Recent research has found that fast-paced beats can increase your exercise intensity and slow, quiet music can even reduce stress. But what type of music is best to help you study?  Los Angeles teacher Kelly K. shares her findings here It is widely accepted that the best environment for concentration is a quiet one; however the majority of students in the US say they prefer to study while listening to music, and in fact the highest achieving students are even guiltier of this.   Why do students do this?   To block out more distracting noise, to motivate themselves, to stay awake or to calm nerves… Whatever the reason, it’s important to find music that will serve your needs, while causing the least amount of distraction. The type of music a student listens to while studying contributes to how much information she can retain and how well she can focus.   The most common type of music students report listening to while studying is popular music.   However, if a person chooses to listen to music while trying to complete a task, is popular music really the best choice? No!   Classical instrumental is by far the better choice.   Inspired by the findings of “The Mozart Effect,” I researched this further for my senior thesis in college.   I had 112 participants and my results were statistically significant.   I found that, on average, students score 90% on spatial reasoning tasks conducted in silence, 83% when listening to classical instrumental music, and 72% while listening to popular music with lyrics.  This means that your choice of music could affect your GPA by a whole letter grade!   One of the reasons for this may be that, due to a person’s capacity for attention, lyrics inhibit ability to focus. Interestingly enough, I found that women are not only more likely to listen to music while trying to complete a task, but they are also more likely to become distracted by it.   So, girls: try to study in a quiet environment, but if you must listen to music, make a good choice and go for classical rather than popular! No matter what the reason, students are more likely to study while listening to music than to study in silence.   So, make a smart decision and go for classical instead of popular it could make the difference of a whole letter grade!

Online Solve by Graphing Tutors

Online Solve by Graphing Tutors Graphing is a very useful method in mathematics. In the method of graphing the given data, expressions or equations are graphed to solve and analyze the given question. Graphs give an overview of the question and help in solving the given question much more efficiently. Graphing is used in various branches such as algebra, trigonometry, statistics and many more. Example 1: Solve by graphing the set of equations y = 3 and x = 2? Solution: The given two equations are x = 2 and y = 3. Here x, y are the unknown variables in both the equations. Graph the equation x = 2 which is parallel to the y axis. Graph the equation y = 3 which is parallel to the x axis. The solution will be the point which is at the intersection of both the graphed lines. Hence the point of intersection is (2,3). Example 2: Solve by graphing the set of equations x = -1 and y = -1? Solution: The given two equations are x = -1 and y = -1. Here x, y are the unknown variables in both the equations. Graph the equation x = -1 which is parallel to the y axis. Graph the equation y = -1 which is parallel to the x axis. The solution will be the point which is at the intersection of both the graphed lines. Hence the point of intersection is (-1, -1). Hence the solution is equal to (-1, 1).

What is A Median in Math - Online Math Tutoring

What is A Median in Math - Online Math Tutoring Median of a distribution is the value of the variable which divides it into two equal parts. It is the value which exceeded by the same number of observations, i.e. it is the value such that the number of observations above it is equal to the number of observations below it. The median is thus a positional average. In case of ungrouped data, if the number of observations is odd then the median is the value after the values has been arranged in ascending or descending order of magnitude. Example: - The following data are the incomes (in thousands of dollars) for a sample of 11 households. 35 29 44 72 34 64 41 50 54 39 58 Find the median of this data set. Solution: -Arrange the data in increasing order, therefore the arrange data: 29 34 35 39 41 44 50 54 58 64 72 Middle term will be the median of this data set. Hence the 6th position is the middle value. 29 34 35 39 41 44 50 54 58 64 72 Median= 44. In case of even number of observations, there are two terms. For example: - Find the median of the values 25 20 15 35 18 40 Solution: - Arrange data are 15 18 20 25 35 40 For this data set median will be the average of two middle term which are 3rd term and 4th term. So Median = (20+25)/2 = 22.5
