Additionally, there are some clinical signals that give an idea about the diagnosis of hypothyroidism especially fatigue and constipation.
Hypothyroidism is concerned with and is a very common secondary cause of dyslipidemia and thyrotropin level measures are indicated.
Hyperlipidemia may show better results to thyroid stimulating hormone.
Hence option D is the right answer.
Since the death rate is higher than the birth rate we can assume that it will be negative. 5-15 is -10 for their life. immigration is also lower than the emigration. 2-4 is -2. adding -2 and -10 will give us -12, hope this helps.
