What does excessive heat do to your body? Heat causes heat exhaustion, which can be dangerous. The longer you spend in the heat, the more serious the effects on your body can be. Increased body temperature can cause heavy sweating, clammy skin, dehydration, tiredness, headache, dizziness, nausea, cramps, and a quick, weak pulse. Can excessive […]

What are 2 types of photoreceptors? Two types of photoreceptors reside in the retina: cones and rods. The cones are responsible for daytime vision, while the rods respond under dark conditions. What is the function of rhodopsin? Rhodopsin, also called visual purple, pigment-containing sensory protein that converts light into an electrical signal. Rhodopsin is found […]

What is the R 2 value in Excel? R squared. This is r2, the Coefficient of Determination. It tells you how many points fall on the regression line. for example, 80% means that 80% of the variation of y-values around the mean are explained by the x-values. In other words, 80% of the values fit […]

Do the number of cells increase? In general, we grow to our full adult size via an increase in the number — not the size — of our cells. But some of our cells can change size — and this can be for healthy or not-so-healthy reasons. Why does the number of cells increase? Explanation: […]

What happens to the acceleration at exactly 2 s? Since there is a sudden change in velocity at exactly 2 seconds in a very short amount of time, we say that the acceleration is undefined in this case. What is the highest acceleration of the car? Read our review McLaren P1, BAC Mono – 2.8s. […]

What is the similarities of principle and theory? Theory and principle are two inter-related concepts. The key difference between theory and principle is that theory is a scientifically credible general principle that explains a phenomenon whereas principle is a basic truth, rule, or law. What is the relation between theory and practice? Practice refers to […]

How far will a 50 watt FM transmitter reach? If 50 Watt ERP is used, it’s very likely that 20 miles of range will be achieved. This is because 50 Watt ERP is ample power to propagate a strong signal 20 miles. If 1 Million Watts of power is used, it is very likely that […]

What is the most complex organic molecule? i-propyl cyanide What are two examples of complex molecules? The four main groups of carbon molecules of life are the most complex organic compounds: proteins, carbohydrates, lipids, and nucleic acids. All complex organic molecules are polymers. What is the longest chemical formula? The IUPAC name for Titin. This […]

Between what two values are the middle 50% of the diameters? The middle 50% of the scores are between 70.9 and 91.1. What is the formula for z score in Excel? 5. To calculate the z-score of a specific value, x, type the following formula in an empty cell: = (x – [mean]) / [standard […]

What are the types of sound based on frequency? Pitch, in turn, depends on the frequency of sound waves. High-frequency sound waves produce high-pitched sounds, and low-frequency sound waves produce low-pitched sounds. Infrasound has wave frequencies too low for humans to hear. Ultrasound has wave frequencies too high for humans to hear. How many sounds […]
