Explain how fish maintain buoyancy?

Biology
1 answer:
Nimfa-mama [501]4 years ago
4 0

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 :)

balandron [24]

Answer:

DNA restriction enzymes cut the DNA molecule, while DNA ligases join the resulting DNA fragments

Explanation:

Transformation is a naturally occurring process by which bacteria incorporate exogenous genetic material from their surrounding environment. This process (transformation) is used for DNA cloning via plasmid vectors. In DNA cloning, transformation occurs after restriction enzymes cut the DNA at specific sequences named palindromic sequences (i.e, sequences that can be read the same in opposite direction). Restriction enzymes can generate sticky-ends, where enzymes make staggered cuts in the two strands (e.g., <em>BamH</em>), or blunt ends, where the resulting strands are of the same length (e.g., <em>HaeIII</em>). In general, sticky-end enzymes are more useful because they generate a 3' overhang in one molecule and a complementary 5' overhang in the other, increasing the yield and specificity of ligation. During ligation, a DNA ligase is used to join both DNA strands by forming phosphodiester bonds in the plasmid. Following transformation, bacteria can be selected on antibiotic plates.

Sati [7]
If a 10 year old child is diagnosed with acute glomerulonephritis and admitted to the pediatric unit, the nurse should TAKE THE VITAL SIGNS EVERY 4 HOURS AND OBTAIN THE DAILY WEIGHT OF THE CHILD.

Glomerulonephritis is a disease of kidney where the glomeruli are injured. It is very important to take measure the vital signs such as taking blood pressure of the child because in this disease acute renal failure might occur that hampers the vital functions of the body. Weighing the child everyday is also important because this helps to know the fluid status in the body.

V125BC [204]

Answer:

Image result for Explain how cells are related to living things.

Cells are the basic building blocks of living things. The human body is composed of trillions of cells, all with their own specialised function. Cells are the basic structures of all living organisms. Cells provide structure for the body, take in nutrients from food and carry out important functions.
