Answer:
It is important that he human trachea is reinforced with cartilaginous rings to keep the passage open as pressure keeps fluctuating during the process of breathing.
Explanation:
The trachea is reinforced with cartilaginous rings as it doesn't allow the trachea to collapse in our day to day lifestyle. It also keeps the air way passage open in spite of the continuous pressure changes during breathing.
The rings are not complete posteriorly to provide another advantage, that is it allows the esophagus to expand anteriorly ( inside the body) when we swallow food.
Answer:
the results of the investigation led to new scientific questions
Explanation:
The basis of every scientific question asked is an observation made. Scientific questions are questions that emanate from an observed problem and leads to the formation of a testable explanation (hypothesis). In this question, an investigation was made by a scientist and it was discovered that increased temperature decreases the number of offspring that an organism produces.
However, the scientist asks a new question about the impact of climate change on the species. This is because an observation has been made again, from the previously concluded investigation. Hence, after completing the investigation about the effect of temperature on the number of offsprings an organism can produce, an observation was made, ultimately leading to a new scientific question.
Based just on the information given, 1.5 million bp.
Nerve cells/neurons are the main structural/functional unit of the nervous system
The best example of a solution is seawater since seawater is a mixture of both salt and water mixed together.
