Answer:
1-The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.
2-The fluid represents the outermost layer of the alveolar surface that is directly exposed to air and thus to the environment. Alveolar fluid prevents desiccation of the epithelial cells and also functions as a physical protection barrier against inhaled particles and irritants.
3-The main function of surfactant is to lower the surface tension at the air/liquid interface within the alveoli of the lung. This is needed to lower the work of breathing and to prevent alveolar collapse at end-expiration.
4-The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic. The bronchioles eventually end in clusters of microscopic air sacs called alveoli.
5- i havent seen the video then how can i answer q5
The shopper should first ask if this claims created by the newspaper is true and is backed up by actual facts. While apple cider and honey do have positive benefits, it is not the answer to all ailments.
Assuming that everything said was true, the shopper then must know whether or not he/she has allergies to apple cider and honey like itching, rashes, difficulty in swallowing, etc.
Lastly, the shopper should ask how much apple cider and honey should he/she take. Too much of both can lead to adverse side effects. If he/she were to consume apple cider and honey exclusively, then they should visit a doctor or a nutritionist in order to get the right amount of intake.
Answer:
B. 1.1
(I just counted the measurements)
Answer:
E. 0.0.
Explanation:
The measure of crossing over coincidence interrelatedness between one cross over and another in a given pair of chromosome is known as what is called Interference.
Given that :
the interference value = 1
The probability of recombination between genes A and B is zero i.e 0.0 because:
when another gene co-occur with a particular gene during cross over, the coefficient of coincidence decreases. We know that the interference is maximum at 1, we can say it ranges from 0-1; now that two recombination is taking place in two genes,the probability is likely to decrease from 1 to 0.0
Similarly; Since the probability of recombination is taking place between two genes i.e genes A and B. Then there is no probability of double crossover when interference value = 1 but when it is zero there is probability of double crossover to occur. With that being said, the probability of recombination between genes A and B is 0.0
