Sound is a type of energy that travels through the air as a vibration of air molecules. It is created when an object or substance vibrates, causing the surrounding air molecules to vibrate as well. These vibrating air molecules then transmit the energy through the air to our ears, where it is detected by the ear drum and converted into electrical signals that our brains can interpret as sound.
Sound waves can have different characteristics, including frequency, amplitude, and wavelength. Frequency refers to the number of vibrations or oscillations per second and is measured in hertz (Hz). Amplitude refers to the size or intensity of the vibrations and is measured in decibels (dB). Wavelength is the distance between the crests of consecutive waves and is inversely related to frequency.
Sound waves can also be classified as either longitudinal or transverse waves. Longitudinal waves, also known as compression waves, are waves in which the vibrations are parallel to the direction of the wave's movement. Transverse waves, on the other hand, are waves in which the vibrations are perpendicular to the direction of the wave's movement.
Sound can be described in terms of its pitch, which is related to its frequency, and its volume, which is related to its amplitude. Pitch is the perceived highness or lowness of a sound and is determined by the frequency of the sound waves. Higher frequency sound waves produce higher pitch sounds, while lower frequency sound waves produce lower pitch sounds. Volume, or loudness, is the perceived intensity of a sound and is determined by the amplitude of the sound waves. Higher amplitude sound waves produce louder sounds, while lower amplitude sound waves produce softer sounds.
Sound is an important aspect of our daily lives and has many practical uses. It is used in communication, entertainment, and even in scientific and medical applications. It is also a key element of music, allowing us to experience a wide range of emotions and feelings through the various pitches and volumes of sound waves.
In conclusion, sound is a type of energy that travels through the air as a vibration of air molecules. It has various characteristics, including frequency, amplitude, and wavelength, and can be classified as either longitudinal or transverse waves. It is also described in terms of pitch and volume and has many practical uses in our daily lives.

Which rat had the fastest basal metabolic rate BMR )?
In normal rat the pituitary gland or the thyroid gland are notremoved and hence will exhibit the highest basal metabolicrate. The pituitaryglands' production stimulates the thyroid to produce thyroxine as well as triiodothyronine. If an animal had been thyroidectomized, what hormone s would be missing in its blood? They found that the rats with the highest VO2 were also the ones with the highest BMR. I only ask that if you find these notecards helpful, you join Easy Notecards and create at least one notecard set to help others out. Cushings disease is most likely to be diagnosed in which patient.

What was the effect of thyroxine injections on the hypophysectomized rat's BMR? My prediction was wrong. How does the BMR in this case compare with the normal rat's BMR? The animal will be missing trioodythronine and thyroxine. How does the BMR in this case compare with the normal rats BMR? THIS SI BECAUSE THE PITUITARY GLAND HAS BEEN REMOVED. Because the surgically altered rats could no longer produce specific hormones t4 and TSH , metabolic rates differed between normal and surgically altered rats. Your BMR is the measure of vitality that your body uses every day on the off chance that you were very still throughout the day. The BMR was just below the normal rat's BMR but still lower.
Which Rat Had The Fastest Basal Metabolic Rate (bmr)?
Your answer:The TSH would be missing because the missing pituitary gland5. Initially, the rat was hypothyroidic 1549. Why did the normal rat develop a palpable goiter with the TSH injection? The dosage was too low. How does the BMR in this case compare with the normal rats BMR? Basal metabolic rate, Energy, Hormone 760 Wor Your Answer The Normal Rat Had The Fastest Basal Metabolic Rate 2 Why Did The Your answer:The normal rat had the fastest basal metabolic rate. Because it has the glands necessary to stimulate and regulate the release of thyroid hormones, the normal rat has the highest BMR. The lack of these organs resulted in lower BMRs due to lack of production of thyroxine. Was the dose of thyroxine in the syringe too large, too small, or just right? How does the BMR in this case compare with the normal rats BMR? The rats with the highest BMR were: 1.
What was the effect of thyroxine injections on the thyroidectomized rat's bmr how does the bmr in this case compare with the normal rat's bmr was the. Since there was an increase in thyroxine levels, the rat developed hyperthyroidism. What factors should be considered when the metabolic rate measured is to be a reliable measure of the basal metabolic rate? Bread has been part of the human diet for thousands of years. Thelevels were a little off. How does the BMR in this case compare with the normal rats BMR? The normal rat was hyperthyroidic because the thyroxine increases the metabolic rate but it did not develop a goiter. Your answer:I would expect to see a lack of TSH in the blood and also a lack of thyroxine and triiodothyronine. Why did ovariectomized rats be used in this study? European house rat Rattus domesticus The rats with the lowest BMR were: 1.
In general larger animals have a lower BMR than smaller animals and males have a higher BMR than females. Why did the BMR's differ between the normal rat and the surgically altered rats? Because it has glands that stimulate and regulate the release of thyroid hormones, a normal rat has the highest bmr.
