An electrocardiogram, abbreviated as ECG in this report, is a visual representation of an organism’s atrial and ventricular depolarization and repolarization. Previous research has shown that although there is variability in the amplitude and shape of the waves of ECG, dependent on the subject’s health, it follows a universal pattern that can be used effectively for biometrics. The experiments discussed in this lab report were performed on Daphnia, humans and crayfish to demonstrate the effects of various stimulus on cardiac activity, i.e. heart rate. The data presented in this lab report was measured via ECG software for human and Crayfish cardiac activity, while the…

Which type of compound usually has higher melting points: ionic compounds or covalent compounds? What is the reason for this difference in melting points? (3 points) Ionic compounds have higher melting and boiling points than covalent compounds. The electrostatic attraction in an ionic bond is very strong hence a lot of heat energy is required to break it down, ionic bonds have high melting and boiling points. In covalent bonds, the intermolecular forces are very weak and are easily broken, hence lesser heat is required and thus covalent bonds have lower melting and boiling points.…

Equine protozoal myeloencephalitis (EPM) is neurological damage caused by lesions on the brain and spinal cord left by protozoa. In the United States, it is estimated that about fifty percent of all horses have been exposed to the organism that causes EPM. However, not all horses will show major signs of the…
The control plates used in transformation are the LB and second LB/Amp plates marked with a “-“. The control for restriction digest was the ladder. The independent variables are the different cultures of the E. coli, and the +LB/Amp and +LB/Amp/ara plates form the experiment group. The dependent variable is whether the cells glow green under the UV light and whether they are resistant to ampicillin or not. The variables in restriction digest are the other 4 samples. The dependent variable is the length that the DNA fragments travel while the independent variable is the size of the DNA fragments.…

In the prison documentary Predators at Prey, we learn about the daily challenges correctional officers face every day. The Lebanon Correctional Institution, located in Ohio, is a rehabilitation based prison that focuses on inmate reentry by offering various services. Just like most other prisons, correctional officers at this institution have to deal with individuals who have committed murder, sex crimes, and drug related crimes. As a result, stress is seen to manifest in different forms in an environment such as this one. Sanford Whitlow, a correctional officer of twelve years, made an interesting observation of correctional officers being unsung heroes who never receive credit for dealing with the worst people in society. Hence, the…

Lab Report Answer the questions below. When you are finished, submit this assignment to your teacher by the due date for full credit. (3 points) ScoreHow do you calculate magnification on a microscope Answer Multiply the lens by the eyepiece magnification to get the total. (4 points) ScoreExplain how to focus a microscope using the high power lens. Include any safety issues you need to be aware of. Answer To focus a microscope using the high power lens, you need to carefully turn the focusing knob, and be careful of the lens so that it doesnt touch the slide. It can damage the lens, or break the slide. (1 points) ScoreWhy is it important to keep a microscope covered when youre not using it Answer It is important to keep a microscope covered when not using it so that it doesnt get dusty, or dirty. (1 point) ScoreSketch what you observe when examining the onion root tip using the low-power lens and the high-power lens. Label the sketches or write a brief description of your observations. Answer Answer is below (1 point) ScoreSketch what you observe when examining the brine shrimp using the low-power lens and the high-power lens. If you saw different forms of the shrimp, try to determine which is more mature and describe the differences. Answer is below Answer SHAPE MERGEFORMAT Your Score___ of 10 Graded Assignment…
