Answer:
Option - E is the same distance from A and B.
Explanation:
Perpendicular bisector can be understood by this explanation:
If line n is intersected by line n at the center of line n
, then line m is the perpendicular bisector of line n
There are 4 right angles formed due to this perpendicular bisector around this mid-point
∵ Line CD ⊥ of segment AB
∴ Line CD intersects segment AB at the middle point of AB
∵ Line CD and segment AB intersected at point E
so, E ∈ AB and E ∈ CD
⇒ Point E is the mid-point of line AB
⇒ E is the same distance from A and B.
Thus, the correct option is - E is the same distance from A and B.
The difference between bronchi and bronchioles is cartilage.
Bronchi have cartilaginous support in the connective tissue that helps keep them open even if the smooth muscle contracts in response to an irritant.
Bronchioles, by contrast, are smaller, have no cartilaginous support, and are at the end of the respiratory conducting system, the tubes that lead directly into alveoli, the gas-exchange epithelium. If the smooth muscle contracts, these tubules can close almost completely, making it very difficult for air to reach the alveoli.
This is what commonly happens in asthma, and it can be a life-threatening condition. Beta-adrenergic agonists of the sort found in “rescue inhalers” can help relax bronciolar smooth muscle and relieve the respiratory symptoms.
Answer:
<em>The above statement is true.</em>
Explanation:
There are certain ethics which have to be followed during the scientific method of research. If these ethics are not followed, the scientific researches can be dangerous or not considered to be applicable.
One such ethic of scientific research is that when taking a biological sample from a research subject, the research subject should be properly guided about how the biological sample will be used for the research project. The research subject should be given knowledge about how the data obtained will be a part of the research object.
