Which lung sound possesses the characteristics of being louder and higher in pitch, with a short silence between inspiration and
andreyandreev [35.5K]

Answer:

C. Bronchial

Explanation:

The different types of lung sounds, also known as breath sounds differ from each other with respect to their location, pitch, relative duration, and intensity.

The bronchial breath sounds are heard just above the clavicle on either side of sternum bone and are characterized by loud amplitude, harsh quality, and high pitch. The bronchial breath sounds are hollow tubular.

The bronchial breath sounds have a short period of silence between the inspiratory and expiratory sounds. The expiratory bronchial sounds last longer than the inspiratory bronchial sounds (I<E).

Describe the actual and relative sizes of a virus, a bacterium, and a plant or animal cell.
anzhelika [568]

Answer :

The animals are categorized into 2 groups - eukaryotes and prokaryotes. The microbes like bacteria are coming under prokaryotes. They are unicellular organisms and without a true nucleus.

Viruses are the connecting link between the living and non - living. They are smaller than bacteria. The microbes less than 100 micrometer can't be seen by the naked eye. They can only visible under a microscope.

Viruses like polio, flu virus sizes are 10nm. But some of the viruses are also less than 10nm. The size of bacteria is 1 micrometer. The viruses are 10 times smaller than the bacteria.

The eukaryotic organisms are more advanced and multicellular. Their cell size is larger than bacteria and viruses. The red blood cells under the light microscope are 8 micrometers. The typical animal cells like sperm are 60 micrometers and a skin cell is 30 micrometers. The plant cell for example pollen is 90 micrometers.

The eukaryotic cells sizes are more than prokaryotes like bacteria.

Both adult and embryonic stem cells have the potential to be used for medical treatment. Evaluate the potential use of adult and
Thepotemich [5.8K]

Stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated. Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells.Research carried out with the use of these cells has demonstrated their effectiveness in the treatment of various diseases, such as leukemia, heart disease and hematological diseases. Embryonic stem cells, in turn, have the ability to form any tissue in the body.

<h3>How are embryonic stem cells used?</h3>

Stem cells have the ability to differentiate and self-renew. For this reason, they can be used in the treatment of degenerative diseases. Stem cells stand out for their ability to transform into different cell types, that is, they are cells with a great capacity for differentiation.

<h3>What diseases could be treated with the use of Embryonic Stem Cells?</h3>

  • Diseases that can be treated with stem cells
  • leukemias. Leukemia is a generic term used to describe the “cancer” of leukocytes, the white blood cells.
  • Thalassemias.
  • Neuroblastoma.
  • Primary immunodeficiencies.
  • Sideroblastic anemia.
  • Metabolic diseases.
  • Sickle cell anemia.

With this information, we can conclude that Scientists are also working on ways to develop stem cells from other cells, using genetic “reprogramming” techniques.

In 2002, the fossil of a four-winged dinosaur was discovered in China and named a microraptor. What was the significance of the
Gnom [1K]

The answer is; It provided clues for scientists to develop a hypothesis about the origin of flight.

Scientists now postulate that dinosaurs are the ancestors of birds. This because the Microraptor is a dinosaur with feathers in all its limbs. It is also the smallest dinosaur to every been discovered and has been compared with the  Archaeopteryx (involving even genetic sequencing) to hypothesize how dinosaurs evolved into birds.
