This means that they do not have enough red blood cells. Normally, the fetus stores iron during the latter months of pregnancy and uses it after birth to make red blood cells. Infants born too soon may not have had enough time to store iron. Loss of blood from frequent blood tests also can contribute to anemia.
The genre of the Time Machine was science fiction. The theme of the Time Machine was that time is a valuable thing and to not take it for granted. As the time traveler discusses the possibility that time is the 4th dimension he provides a miniature model of the time machine that vanishes in front of his guests eyes.
A digital alarm clock displays the time digitally using electronic components instead of using hands, springs, and gears. Instead of the oscillating wheel, the digital clock uses an electronic time-base that counts off the seconds, keeping time accurately. In place of the analog clock's gears, the digital clock uses a counter and an liquid crystal display (LCD) or a light-emitting diode (LED), which is a two-lead semiconductor (material that conducts electric current) light source. Digital clocks rely heavily on electronic parts such as capacitors and resistors, as these devices manage the flow of electrical current.
