Datura stramonium, known by the English names jimsonweed or devil's snare, is a plant in the nightshade family. It is believed to have originated in Mexico but has now become naturalized in many other regions. Other common names for D. stramonium include thornapple and moon flower, and it has the Spanish name toloache. Datura has been used in traditional medicine to relieve asthma symptoms and as an analgesic during surgery or bone setting. It is also a powerful hallucinogen and deliriant, which is used entheogenically for the intense visions it produces. However, the tropane alkaloids responsible for both the medicinal and hallucinogenic properties are fatally toxic in only slightly higher amounts than the medicinal dosage, and careless use often results in hospitalizations and deaths.

Carbon chains are principal features of both carbohydrates and lipids.what is the primary difference between these two types of

solong [7]

While both carbohydrates and lipids are made up of carbon, hydrogen and oxygen there are several differences:

1. Carbohydrates are chains of 2 or more carbon atoms. These can be very lengthy (like long cellulose chains of glucose units). They have many polar OH groups (e.g. glucose - C6H6O6). Most carbohydrates are hydrophilic and are soluble in water because of their polar OH groups. They are not necessarily sugars nor are they necessarily sweet. They are also important components of DNA, RNA and ATP.

2. Lipids are more diverse in their chemistry. They generally have a polar region at one end (this end attracts water) and a large non polar hydrocarbon region that repels water. Lipids don't dissolve in water and instead clump together with their hydrocarbon regions on the interior. Lipids include oils, fatty acids, waxes, steroids and hormones.

Vitamin B3 (niacin). Helps the body turn food into energy and use fats and protein.

Vitamin B6. Keeps the brain and immune system healthy.

Vitamin B12. Keeps nerve and blood cells healthy, and makes DNA -- the genetic material in every cell.

Vitamin C. Protects against infections, builds bones and muscles, and helps wounds heal.

Vitamin D. Helps the body absorb calcium from food, and keeps bones and teeth healthy. Breast-fed babies may need a D supplement.

Vitamin E. Protects cells from damage, and strengthens the immune system.

Y_Kistochka [10]

The answer is a simple radial nervous system.

Echinoderms do not have brains. Around their mouth, they have central rings from which nerves radially run into arms and along the body. Movement is controlled by the branches of those radial nerves.

Has medical progress stopped human evolution? [duplicate]

Angelina_Jolie [31]

No. Medical progress is allowing us to progress and evolve in different ways. That is the only difference. Having medical progress and good medical care allows us to pursue different types of activites we wouldn't be able to pursue otherwise. This at the same time brings a different type of evolution.
