BIOLOGY 2020 LAB LAB 4 – Sensory Systems I. Vision 1. Know the types of photoreceptors in the retina. (Remember there are 3 different types of cones) 3 cones i. Blue- short ii. Green- Medium iii. Yellow-Red- Long 2. Why would near point accommodation change as you get older? (Think about what happens to the lens and the muscles of the eye with age) As you get older‚ the lens becomes hardened. The elasticity of the lens decreases dramatically with age‚ resulting in difficulty

Gabi Mejia Chem 101 Section ADF Lab 4: Weak Acid Unknown Procedure: When testing the acid‚ use only between 0.2 g and 0.3 g for each trial (get as precise a measurement as you can). The general procedure is to weigh out your acid‚ dissolve it in water‚ add a couple drops of the indicator (phenolphthalein)‚ and then add the sodium hydroxide until you note a color change (from clear to pink). When the color change occurs‚ you have added enough base to completely react with the acid (the endpoint).

America ranks thirty-second in math. It is because students fail to see the benefits of math. The average scholar is more interested in extracurricular activities. While these activities are enjoyable and can be educational‚ we must not stray away from the core subjects. Out of the core subjects’ math ranks supreme in most aspects. Math can be cumbersome at times‚ yet it allows for a more enjoyable job and life. When it comes to school subjects‚ Math is the superior choice since

The purpose of Lab 4 was to experiment with the vi editor commands. In the lab‚ the “garden” file was edited in many different ways. Many commands were explored in this lab including the ab‚ U‚ yy‚ dd‚ w‚ set number‚ set showmode‚ and paging commands. Step 1: Boot up the computer by pressing the power button. Step 2: Select Oracle Virtualbox using the mouse. Step 3:Open Fedora by using the Virtualbox Machine and click start when Fedora is selected. Step 4: With the vi editor in command mode

have our equation of ay^2+by+c=c Step 2: y= (-3) ± (-3) ^2-4 (2) (-6) /2 (2) We plug in our terms Step 3: y= 3± (-3) ^2-4 (2) (-6) /2 (2) We *by -1 to our terms outside the radical then do the math and simplify inside the radical Step 4: y=3 +57 /2 (2) Simplify the denominator. Step 5: y=1/4 (3+ 57 ) Next we need to solve for ± Step 6: 1/4 (3 - 57 ) Next we solve for – Solve: 1/4 (3 + 57‚¼ (3-57) The final answer gives us the following result:

Math is one of the basic sciences of life; it can be said that is the most basic science‚ the first thing a person learns‚ apart from reading and writing‚ is how to add and subtract. But‚ is math a part of nature‚ or was it made to measure or understand nature? It is really hard to know‚ but in my point of view‚ math is a method created by men to measure nature. If math was a part of nature‚ man would be born with math knowledge‚ but man is not‚ man had to think about a way to count and measure things

“Once I get into algebra‚ my parents will have to help me with my homework.” “I don’t need to know a lot of math.” “Math is so boring.” “I’m just not good with numbers. If I need to know that stuff‚ I ask my boyfriend.” Does any of the above sound familiar? Or do you also feel what others feel about their Mathematics subject? Don’t be dismayed‚ you’re not alone. There are many. While the geeks and nerds are enjoying problem solving‚ others surely hate the ancient Greeks for inventing Mathematics
