Answer:
Contains large polytene chromosome that permit visual inspection of genomic events.
Were used to study the genetic effects of mutations.
Were used to establish the concept of chromosomal inheritance.
Explanation:
<em>Drosophila melanogaster </em>is a model organism that is used by scientists to study the genes and effect of a mutation on the genes. Drosophila is used as a model organism as it has a very short life cycle and the offspring can be produced in a short duration of time.
Because of these characteristics, Thomas Hunt Morgan wanted to study the factors of inheritance on the <em>Drosophila</em> and concluded in the form of the chromosomal theory of inheritance by the effect of mutation on genes that lead to linkage mapping.
Also, the salivary gland of fruit fly contains the polytene chromosome which allows us to look into the gene events.
Thus, the selected options are correct.
When a client comes into the emergency room (er) after hitting his head while playing any sport, if he is alert and oriented. immobilize the client´s head and neck would be a priority nursing intervention, because a head injury is treated as if a cervical spine injury is present until x-rays confirm their absence, then call for an immediate head computed tomography to look for any spine or head injury.
The Golgi bodies are the empty structure in the cytoplasm. The Golgi apparatus or Golgi complex is found in most cells. It is another packaging organelle like the endoplasmic reticulum<span> (ER). It was named after Camillo Golgi, an Italian biologist. It is pronounced GOL-JI in the same way you would say squee-gie, as soft a "G" sound. While layers of membranes may look like the rough ER, they have a very different function.

Answer:
preventing friction between bones
Answer:
Complete questions include: Answer Bank: Guanine nucleotides, uridine nucleotides, adenine nucleotides, cytosine nucleotides.
Explanation:
Glycine Auxotroph: Guanine nucleotides and adenine nucleotides (Purine nucleotides)
Glutamine auxotroph: Guanine nucleotides and adenine nucleotides (purine nucleotides)
Aspartate auxotroph: Guanine nucleotides, uridine nucleotides, adenine nucleotides, cytosine nucleotides Both purine and pyrimidine nucleotides)
The amino acids glutamine, glycine, and aspartate provide all the nitrogen atoms of purines in a two ring-closure steps to form the purine nucleus. Pyrimidines are synthesized from carbamoyl phosphate and aspartate.
