Most fish (especially the "Bony fish") achieve neutral buoyancy through a sac called the swim bladder in there body of which is filled with air, not much but it'a just enough to keep then a float. The fish can control this organ, and using that they can fill or release air to allow them to rise or sink.
Cartilaginous fish however, do not have a swim bladder.
hope this helps :)
Answer:
9:3:3:1
Explanation:
There are 420 kernels, over half of these are purple wrinkled (242/420=0.576) one fifth are purple smooth (84/420=0.2), just under one fifth are yellow wrinkled (70/420=0.167), and just over one twentieth are yellow smooth (24/420 = 0.057).
The ratio is 0.567: 0.2: 0.167: 0.057
0.567/0.057 = 9.9, so the ratio of purple wrinkled to yellow smooth is around 9:1.
0.567/0.2 = 2.835 and 0.567/0.167 = 3.39, so the ratio of purple wrinkled to purple smooth and yellow wrinkled is approx 3:1
0.2/0.057 = 3.5 and 0.167/0.057 = 2.92, so the ratio of purple smooth and yellow wrinkled to yellow smooth is approx 3:1
Therefore, the ratio is approximately 9:3:3:1.
This is a classic Mendelian ratio for a independent assortment associated with a dihybrid cross.
A Computed tomography (CT) takes several x-rays to reveal deformities in shape and structure that are connected with blood clots, tumours, and other health problems.
Computed tomography (CT) uses x-rays to create images that show the structure of the brain and the areas of damage.
What is Computed tomography (CT) ?
- A computed tomography scan is a medical imaging technique used to obtain detailed internal images of the body.
- The personnel that perform CT scans are called radiographers or radiology technologists.
- CT scanners use a rotating X-ray tube and a row of detectors placed in a gantry to measure X-ray attenuations by different tissues inside the body.
- CT scan can be used in patients with metallic implants or pacemakers, for whom magnetic resonance imaging (MRI) is contraindicated.
