If you have type O blood, ketsueki-gata suggests that you are confident, self-determined, strong-willed and intuitive; unfortunately, you are also self-centered, cold, unpredictable and potentially a workaholic.
Smoking during pregnancy affects your and your baby's health before, during, and after your baby is born. The nicotine (the addictive substance in cigarettes), carbon monoxide, lead, arsenic, and numerous other poisons you inhale from a cigarette are carried through your bloodstream and go directly to your baby. Smoking while pregnant will:
<span>Lower the amount of oxygen available to you and your growing babyIncrease your baby's heart rate<span>Increase the chances of miscarriage and stillbirth</span>Increase the risk that your baby is born prematurely and/or born with low birth weightIncrease your baby's risk of developing respiratory problems</span>
The more cigarettes you smoke per day, the greater your baby's chances of developing these and other health problems. There is no "safe" level of smoking for your baby's health.

Answer: option B) Sympatric speciation is best described as a random event that disrupts the allele frequencies in a population
Explanation:
Sympatric speciation is an event/situation whereby organisms of the same species:
- live in the same territory or nearby territories ( i.e do not live in geographical isolation)
- DO NOT interbreed, but select a sexual mate from a much diverse territory to yield new species or offsprings.
This sexual selection then results in generations of offsprings that are genetically different from the rest of the same species due to uneven gene flow or disruption of alleles among the population of same species.
Thus, only option B is true.
Answer: Fluorescence microscope
Explanation:
The basic function of a fluorescence microscope is to irradiate the specimen with a desired and specific band of wavelengths. A fluorescence microscope uses a mercury or xenon lamp to produce ultraviolet light. The light comes into the microscope and hits a dichroic mirror. The dichroic mirror reflects the ultraviolet light up to the specimen. The ultraviolet light excites fluorescence within molecules in the specimen. The objective lens collects the fluorescent-wavelength light produced. This fluorescent light passes through the dichroic mirror and a barrier filter, making it to the eyepiece to form the image.
