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 Free Essays
The metabolic rate was increased by thyroxine. The normal rat was hyperthyrodic because the thyroxine increases the metabolic rate but it didn'tdevelop a goiter. Compare the baseline metabolic rates for the thyroidectomized rat and the normal rat and explain your results. The dose of thyroxine was just right because it did not cause the thyroidectomized rat to develop a goiter. What was the effect of thyroxine injections on the hypophysectomized rat's BMR? It can be for any subject or class. Why was this effect observed? The BMR was just below the normal rat's BMR but still lower.
If an animal has been thyroidectomized, what hormone s would be missing in its blood? The palpable goiter was due to buildup of the precursors of thyroxine. My prediction was correct. THIS SI BECAUSE THE PITUITARY GLAND HAS BEEN REMOVED. The administration of thyroxine injections on thehypophysectomized rat resulted in increased basal metabolic rate BMR. How does the BMR in this case compare with the normal rat's BMR? Male rats have a higher basal metabolic rate than female rats. Further research is needed to determine the exact reasons for these differences in BMR between different species of rats. COMPARE THE BASELINE METABOLIC RATES FOR THE HYPOPHYSECTOMIZED RAT AND THE NORMAL RATAND EXPLAIN YOUR RESULTS.
Which rat had the fastest basal metabolic rate BMR )?
A goiter did not develop. Propylthiouracil ptu side effects propylthiouracil is the drug is approximately 70% protein-bound and significantly ionized at normal. How does the BMR in this case compare with the normal rats BMR? Because it has glands that stimulate and regulate the release of thyroid hormones, a normal rat has the highest bmr. Your answer:The TSH would be missing because the missing pituitary gland5. In a study published in 2008 scientists measured the VO2 of 10 different species of rats.
Which Rat Had The Fastest Basal Metabolic Rate (bmr)?
. BMR was sti Endocrine System Physiology Which rat had the fastest basal metabolic rate BMR? If an animal has been hypophysectomized, what effect would you expect to see in the hormone levels in its body? An injection of thyroxine to an otherwise normal rat will cause which of the following? 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. What was the effect of propylthiouracil PTU injections on the normal rats BMR? The effect of TSH was to increase the normal rat's BMR 9 What was the effect of TSH injections on the thyroidectomized rats BMR? If an animal has been thyroidectomized, what hormone s would be missing in its blood? Brown rat Rattus norvegicus 2. What was the effect of thyroxine injections on the normal rat's BMR? The normal rat that was injected with thyroxine Why did the metabolic rates differ between the normal rat and the surgically altered rats? This preview has intentionally blurred sections. It has a pituitary gland so some hormones are still there. Why did the metabolic rates differ between the normal rat and the surgically altered rats? It raised the metabolic rate but not as high as the thyroidectomized or normal rats. COMPARE THE BASELINE METABOLIC RATES FOR THE THYROIDECTOMIZED RAT AND THE MORNAL RAT AND EXPLAIN YOUR RESULTS.
Stress and body weight changes variations in food and water consumption, urine volume, and bmr were also observed twelve rats were subjected to tone. The metabolic rate was increased to 1910 which was not as high as the baseline. The BMR increased for the thyroidectomized rat with thyroxine injections. If an animal had been hypophysectomized, what effect s would you expect to see in the hormone levels in its blood and in its BMR? Therefore,thyroxine caused an increase in the rat's BMR. How well did the results compare with your prediction? The BMR remained consistent with the 1st trial where there was no injection C Hypophysectomized rat - hyperthyroidism developed and a goiter was present. Here's how to do the bmr calculation manually take your lean weight and multiply by 115 for men, or 120 for women that gives you a typical overall body. Initially, the rat was hypothyroidic 1549.
What was the effect of thyroxine injections on the thyroidectomized rat's BMR? This plays an important part in hormone secretion to raise or lower BMR. Due to the increase of TSH, the amount of thyroxine increased which resulted in an increased BMR. . Hypercortisolism occurs as a result of a tumor in the anterior pituitary gland, and it is characterized by elevated cortisol and adrenocorticotropic hormone levels. Having rats running around infected with possibly fatal diseases is far too dangerous. Part 2: determining the effect of thyroxine on metabolic rate what was the effect of thyroxine Metabolism And Thyroid Hormone Lab endocrine System Flashcards Preview Which rat had the fastest basal metabolic rate BMR?

Was the dose of thyroxine in the syringe too large, too small, or just right? How does the BMR in this casecompare with the normal rat's BMR? Bread has been part of the human diet for thousands of years.
So without the thyroid the animal would be missing thyroxine andtriidothyronine in its blood. 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. However the BMR was still on the lower side in comparison tothe basal metabolic rate seen in the case of normal rats withthyroxine. . Which rat had the fastest basal metabolic rate BMR? Why did this rat develop a palpable goiter? Describe the diagnosis for patient 3, who was also pregnant at the time of this assay.
If an animal has been thyroidectomised, the two hormones thatwould be missing for its blood is triiodythronine andthyroxine. There would be a lack ofTSH because that is what the pituitary glands produce and there would be a lack of thyroxine and triiodothyronine becauseTSH is what stimulates the thyroid produce them.
