Answer:
Sphingomyelin and glycolipids are precursors of ceramide.
Glycolipids are sugar molecule(s) attached to a membrane lipid.
Ceramide can be made into either sphingomyelin or a glycolipid depending on what enzyme encounters ceramide first.
Sphingomyelin is a phospholipid made in the Golgi.
Explanation:
Simple sphingolipids are the ceramides. Glycolipids, a large group of sphingolipids, contain one or more molecules of sugar (glucose or galactose).
Lipids that are synthesized in the ER (not in the RER) are cholesterol and ceramide which is further converted to either glycolipids or sphingomyelin in the golgi apparatus. Ceramide can then get sent to the Golgi, where it can be converted into either glycolipids or the only non-glycerol-based phospholipid, sphingomyelin.
SER (not RER) is involved in the synthesis of lipids, including cholesterol and phospholipids, which are used in the production of new cellular membrane.
I think its because with hurricanes they destroy their habitats and their food supply making it harder for the animals to hunt and live. This cause them to force adaption meaning they are forced to find a new habitat to live them. With that the animals are affected with slow decomposition. It is hard for animals to find a new habitat or adapt to a new place because they are so use to different temperatures like for example if an animal is use to being in the cold like polar bears in the artic and with the artic melting they are forced to live in the warmer climates which is hard for them so they slowly die. Thats how the animals are affected during hurricane Katrina.
Hope this helped. <span />
Answer:
Explanation:
Genetic engineering is faster than the process of natural selection.
Natural selection is natural process and it works over generations, while genetic engineering involves desired modification of traits.
Both genetic engineering and natural selection work on all organisms, including humans.
Answer:
Sea stars are slow moving, but a time lapse film by biologists Don Wobber and John Pearse shows how they use their arms to interact with each other on a regular basis. They touch each other as if getting a sense of the others size, and often wrestle for a position of dominance over territory.
Explanation:
Answer:
Settlement houses were safe residences in poverty-stricken, mostly immigrant neighborhoods in major cities such as New York, Boston, and Chicago. The settlement house movement began in England and then emerged in the U.S. in 1886 with the founding of University Settlement House in New York City.
