It is hypothesized that fish have higher respiration rates in warmer water because metabolic rates are faster in a warmer climate for exotherms. Results show that the respiration rate of fish was greater in the 76 degree Fahrenheit tank (mean=203 breaths per minute) than in the 71 degree Fahrenheit tank (mean=79 breaths per minute) (p=0.04). Another trend observed is that , although not significant, was that smaller fish have a higher respiration rate than larger fish in both temperatures (p=0.19).
This is known as the validity of a test. It is the degree to which a test accurately measures what it claims to measure. High validity indicates that the test is accurately assessing the intended construct or concept.
To accurately measure liquid, you can use equipment such as graduated cylinders, beakers, measuring cups, or pipettes, depending on the volume of liquid you need to measure. Each of these tools has graduated markings that allow you to determine the exact volume of liquid accurately.
The volume of gases is measured with gas-meters.
Validity is the extent to which a measurement tool actually measures what we wish to measure.
The rate of respiration is the number of breaths per minute. All you have to do is count either the number of breaths in OR out (not both) in one minute. To get more reliable results, the experiment should be repeated several times.
To measure weight accurately, we use a scale.
A graduated cylinder is commonly used to measure liquids accurately.
Catabolic
using a thermometer u can measure accurately at 1 decimal place
To measure tire pressure accurately, you can use a tire pressure gauge.
To measure a bike's height accurately, stand the bike upright and measure from the ground to the top of the seat post. This measurement is the bike's height.
To accurately measure a screen door, use a tape measure to measure the height and width of the door frame. Measure from the inside edges of the frame for both dimensions. Make sure to measure in inches for accuracy.
To accurately measure the diameter of a bike stem, use a caliper or ruler to measure the width of the stem at its widest point. Make sure to measure in millimeters for precision.
Remove the seat post from the frame and measure the bottom accurately with calipers.
To accurately measure your bike inseam, stand with your feet shoulder-width apart and measure from the floor to your crotch. This measurement is your bike inseam. Make sure to measure in centimeters for accuracy.
To measure a bottom bracket accurately, use a caliper to measure the width of the bottom bracket shell and the diameter of the bottom bracket cups. Make sure to measure in millimeters for precision.
To measure 100 grams you need a weighing scale to accurately measure it.
