Answer:

Cystic fibrosis is a genetically transmitted or heriditary disease.

Explanation:

In cystic fibrosis the lungs and the digestive system get effected. It causes the CFTR protein (Cystic Fibrosis Transmembrane conductane Regulator) to become dysfunctional. Due to this dysfunction, chloride become unable to move.  for this reason mucus clogs the airways in the lungs which leads to respiratory failure and other complications. The gene responsible of this disease located at the long arm of chromosome number 7. Of all ethnic groups, caucasians have the highest inherited risk of this disease.

Why is a high use of renewable energy necessary to make hydrogen fuel an environmentally sound alternative?
Elan Coil [88]
Hydrogen is similar to electricity. Although an electric vehicle, for an example, doesn't create any tail pipe emissions from the vehicle, that may not be the case where the electricity was made. If the electricity was made from an old, smoking, worn out gasoline powered generator in order to charge the electric vehicle, the total pollution created would be much more than that made by a regular gasoline car. However, if the electricity is made by an environmentally friendly renewable source, such as solar or wind, then the total pollution created in powering the electric vehicle would be much less, perhaps even zero. 

<span>Hydrogen can be made from electricity or petroleum. If made from petroleum it wouldn't be much different than gasoline because the rest of the petroleum would have to be used somewhere. If the hydrogen is made from electricity then the question again is where is the electricity being made. </span>

<span>Your question is also a good one because it highlights the "high use" of renewable energy. The production and use of hydrogen in less efficient than running just off of electricity. So you'd have to produce a whole lot more electricity to make hydrogen to drive a car a certain distance than to charge a battery-electric car and drive the same distanc</span>

The amino acid chain breaks away from the ribosome and folds into a protein.
mezya [45]

The correct order of steps is 3, 2, 4, and 1.

<h3>What is translation?</h3>

It is a process whereby the genetic codes in transcribed mRNA molecules are translated into their respective amino acids.

The steps involved in translation are:

  • Transcribed mRNA leaves the nucleus and travels to the cytoplasm where it gets attached to the ribosome
  • tRNA molecules bring the amino acids coded for by the RNA from the cytoplasm and begin to assemble them
  • The amino acid chain grows as the mRNA molecules are read by the translation machinery (the ribosome) and more amino acids are brought from the cytoplasm.
  • The amino acid chain breaks away from the ribosome and folds into a protein.

Thus, the step is 3,2,4, and 1.
