Answer:

Each one has two fatty acid chains and the glycerol backbone is bonded to a small polar group.

Explanation:

Phospholipid is a unique form of lipid. The  bonding of the glycerol backbone to the polar phosphate group makes phospholipid to have dual solubility unlike general triglycerides.

 

The polar head is said to be hydrophillic that is <u>water loving,</u> while the two carbon chains  that  retained lipid features are hydrophobic <u>water hating.</u>

Therefore if a phopholipid is placed in water, in relation  to its functions as component of cell membrane, it forms a bi-layer in which the water loving portion hydrophilic head points into the surrounding watery medium, while the hydrophobic layer points inwards far away from the watery medium into the internal cellular  layer to form an impermeable barrier to hydrophilic (polar) substances.

This forms the basis of   the  phospholipd  bilayer  of the  cell membrane. And it  controls the permeability of the cell membrane to  influx  substances  into the cells.

Answer: The best way for farmers to prevent fungi from growing is to make sure there is not enough  moisture for fungi to survive and grow

Explanation: Fungi require moisture or water for a wide number of reasons. One of the best guesses I can give as a reason to why they might need it is to help them in the process of digestion. Fungi use digestive enzymes which are specially shaped proteins that break down macromolecules like glucose or cellulose and a number of other biological molecules, and they do this through one of two processes, dehydration synthesis, or hydrolysis. Hydrolysis in particular is the one that requires water. It uses pieces of water to break a bond between complex sugars and carbohydrates among other molecules, to separate them into smaller and easier to absorb monomers which are the subunits that make up the molecule. It breaks apart the water and uses the pieces to fill in the gaps of the pieces the monomers used to share.

6. In Chicago "Smiling Gus" Winkler met up with some of Chicago's most famous gangsters. They included:
viktelen [127]

Answer:

Al Capone, Fred "Killer" Burke, and Bugsy Moran.

Explanation:

Augustus "Smiling Gus" Winkler was a big-time gangster who had his fingerprints surgically altered so as not to be identifiable through fingerprint technology. He was part of Eagan's Rats gang and would participate in some of the most notorious crimes such as the St. Valentines Massacre in 1929.

When he moved up north, he met up with some of the world's famous gangsters like Al Capone, Roger Touhy, Fred Burke, and Bugsy Moran. But in 1933, to secure himself, he turned evidence against his friends and accomplices. But he was not to be safe for long, for he was gunned down by unknown assailants rumored to be ordered by Frank Nitti on October 9, 1933.
