Answer:

Most likely diagnosis is Basal Cell Carcinoma (BCC), most likely caused by years of prolonged exposure to sunlight over time.

Explanation:

Basal Cell Carcinoma (BCC) is a common type of skin cancer that develops when the basal cells that is responsible for producing new skin cells when they die, become mutated and causes the basal cell to abnormally multiply rapidly and continues to grow. The accumulation of these abnormal cells is what results  in cancerous tumors that appears like ulcers on the skin. Prolong and intense exposure to the ultraviolet (UV) radiation from sunlight has been linked to the most likely cause for the mutation of the DNA in the basal cells which leads the abnormal cell growth and multiplication. People who expose themselves to the radiation of the sun for longer periods, over time, are at high risk of developing this cancer.

poizon [28]

Hello there!

Your answer would be lung cancer, chronic bronchitis, emphysema and asthma.

Years of smoking and exposure to air pollutants can contribute to the incidence of lung cancer, chronic bronchitis, emphysema and asthma.

Lung cancer is one of the factors that is caused by smoking and air pollutants. This happens when too much lung cells are being produced in the lungs at once, which causes cancer cells to grow, this would form a tumor in the lung. There are many treatments that could be taken to remove this tumor. This is one of the things that are caused by smoking and air pollutants.

Chronic Bronchitis is another factor that is caused by smoking and air pollutants. This also involves the lungs. Chronic Bronchitis is a disease in the lungs that caused inflammation in them, which is very dangerous to the human body. Growth of mucus, coughing, and etc are symptoms of this. This is another factor that is caused by smoking and air pollutants.

Emphysema is another factor that is caused by smoking and air pollutants. This is a disease that causes the alveoli (a balloon shaped pass way in the raspatory system) to over swell. This mostly causes a shortness of breath to a person. This is another factor that is caused by smoking and air pollutants.

Asthma is another factor that is caused by smoking and air pollutants. This condition is very common to people who have smoked, been around smoke, or has been around places whose air is very polluted. This conditions causes the airways to clog up, which makes it hard to breathe. This is another factor that is caused by smoking and air pollutants.

astra-53 [7]

Answer: Option (c) is the correct answer.

A long hydrocarbon chain that consists a terminal carboxylic group is known as a fatty acid.

An unsaturated fatty acid consists a double bond within the fatty acid chain. If a fatty acid contains more than one double bond then it is known as polyunsaturated fatty acid.

For example, oelic acid has chemical formula C_{18}H_{34}O_{2} is an unsaturated fatty acid.

Therefore, we can conclude that option (c) represents an unsaturated fatty acid.

Answer:

Because salt is soluble in water, salt applied to such surfaces dissolves. Liquid water has what is known as a high dielectric constant, which allows the ions in the salt (positively charged sodium and negatively charged chlorine) to separate.
