This is just an educated guess. As the purple pigment, caused by anthocyanins, are on the bottom side of the plant, their purpose could probably be to direct the light. Specifically, a purple pigment on the bottom of the plant would absorb certain wavelengths near the purple spectrum, and reflect other wavelengths back toward the portion of the plant with chlorophyll. In this way, light does not simply pass through the leaf, instead it is reflected back in towards the chlorophyll to maximize the amount of light being used for photosynthesis.

Do you think smoking has negative effect on fetal development?
n200080 [17]

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.

Science provides only a
melomori [17]

Science provides only a limited understanding of the supernatural, or other ways of knowing, such as art, philosophy, or religion is a true statement.

<h3>Why science provide limited information about supernatural?</h3>

Science provides only a limited understanding about supernatural, aesthetic, or other ways of knowing, such as art, philosophy, or religion because they are not proved by the science through experiments. These things are beyond from explaining them. Science can't explain the happening of supernatural phenomenon. Science does not create moral or ethical rules, laws, or judgements. Science deals with only things that can be observed or measured so that's why science is not understanding supernatural things.

So we can conclude that Science provides only a limited understanding of the supernatural, or other ways of knowing, such as art, philosophy, or religion is a true statement.
