The answer is D) <span>Calculate the probability of a child having either sickle-cell anemia or cystic fibrosis if parents are each heterozygous for both. 

The addition rule is used to calculate the probability of one of the events from multiple pathways. If you want that only one of the events happens, you will use the addition rule. In a case when you want to calculate the possibility of a child having EITHER sickle-cell anemia OR cystic fibrosis, you will use THE ADDITION RULE.
For example, in statement B) you will not use this rule because there is no either/or, but both/and. In case, B) you would use the multiplication rule.</span>

I am an important respiratory organ that is located near the back bone on either side of the heart. My main function is to transport oxygen form the atmosphere into the bloodstream and also release the carbon dioxide produced within the body out in the atmosphere.

Please quit smoking, cigarette smoke contains thousands of harmful chemicals so which can causes me (lungs) to be filled with smoke. If you continue to smoke it can cause a serious lung disease like lung cancer. Do not allow people to smoke in your house, car or workplace  

Limit your exposure to pollutants please avoid highly polluted and industrialized areas because if you inhale air that is polluted can cause long term effects like irritation and difficulty in breathing  

Do deep breathing daily exercise. daily sit down and inhale deeply with your nose. Count to five and slowly exhale the air. Repeat this exercise six to eight times daily to help cleanse me (lungs) and keep yourself stress free

Eat fresh and healthy. Eat garlic, It is an antibacterial that can help to clear pathways of bronchi and helps to flush out mucus and cough thus making the nasal air passage clear. Drink apple juice to keep any of my (lung) diseases away. Add ginger in your daily diet to detoxify me (lungs)
