Answer:
It is well known that women with poorly controlled PKU during a pregnancy put their baby at risk for developmental issues, poor head growth (microcephaly), poor overall growth, heart defects, and other structural birth defects.
Explanation:
18% because C pairs with G. A pairs with T. T and C are not complementary base pairs, but we do know that if a molecule consists of 32% T, it must have 32% A as well.
32 + 32 = 64
100 - 64 = 36
36 ÷ 2 = 18
There must be 18% of C.
With a light microscope one can view the nucleus and endoplasmic reticulum, large vacuoles etc
The resolution of a light microscope is dependent on the wavelength of light that is the main beam of illumination. Light has approximately 0.4 um (UV)- 0.7um (Infrared) wavelength. Organelles smaller than about 0.5 um will be difficult to discern with a light microscope.
With an electron microscope one can view, in addition, even the ribosomes and mitochondria, chromosomes, tubules etc.
An electron microscope can discern very minute details of a cell. This is because its resolution is dependent on the very small wavelength of a beam of electrons which is approximately 0.002 um (about 10,000 times powerful than a light microscope)
Tachycardia is a condition when the heart rate is greater than 100 beats per min at rest. The electrocardiogram is a diagnostic tool that measures and records the electrical activity of the heart. Bradycardia on the other hand is when the heart rate is slower than normal. The Tachycardia and bradycardia can arise from either the SA node or from other areas of the cardiac.
