Denaturation of Proteins - 647 Words
Denaturation of proteins involves the disruption and possible destruction of both the secondary and tertiary structures. Since denaturation reactions are not strong enough to break the peptide bonds, the primary structure (sequence of amino acids) remains the same after a denaturation process. Denaturation disrupts the normal alpha-helix and beta sheets in a protein and uncoils it into a random shape. Denaturation occurs because the bonding interactions responsible for the secondary structure...

Carbohydrates, Protein, Lipids, and Dna
Carbohydrates have two major functions in plants and animals: they serve as fuel and building material. Plants store most of their energy in the form of starch. Starch is a polysaccharide (consisting of several conjoined sugars). Synthesizing starch enables the plant to stockpile surplus glucose, and since glucose is a major cellular fuel, starch represents stored energy. The sugar can later be withdrawn by hydrolysis, which breaks the bonds between monomers. Animals, in turn, have enzymes...

The original chocolate morsels were literally chips off the old block: Chocolate used to be sold as a bar with its very own chopping device. It wasn't until the 1930s that manufacturers began making convenient precut morsels, perfect for melting, baking, or scarfing by the handful. Have half a bag sitting in your pantry right now? Pull them out and give these easy, surprising (no cookies in sight!) recipes a shot. Just remember: You can use bittersweet and semisweet interchangeably in recipes, but milk chocolate morsels will give you a sweeter, creamier result.

Public Safety Advisory - Concerning 911 Calls
The South Simcoe Police is alerting the public to technical 9-1-1 limitations to help ensure that when someone calls 9-1-1 for help using wireless (cell phone) or Internet-based (VoIP) technology, emergency services can locate them with the least delay possible.
9-1-1 call takers and dispatchers need to know a caller's exact location in order to direct the nearest police, fire or ambulance services to the emergency. Response delays may result if exact location information is not provided by the caller.
The traditional 9-1-1 system is based on the use of landlines and ensures that an emergency telephone call goes to the correct 9-1-1 Centre. At the same time, the system automatically provides address and telephone number information to ensure help can find the caller even if the person is unable to verbalize the location or nature of the emergency. At this point, this is not guaranteed with wireless and new Internet-based technology.
Most cellular providers now have an enhanced 911 service that allows emergency operators to view the wireless caller's phone number and the location of the cellular tower handling your call, but not the specific location from which the call is being made or where the emergency is. It is up to the caller to describe the exact location of the emergency.
Even if a consumer has registered their cell phone or VoIP telephone service and personal location with a service provider, given the portability of the technology, it is possible that a 9-1-1 call may be made from a different location. VoIP services can be used from any computer with high-speed Internet access and therefore are not associated to a specific municipal address. Cell phones may display the phone number but not the location from which the call is being made.
Consequently, location information and the nearest, associated emergency agencies are not automatically available to the 9-1-1 call taker/dispatcher.
Subscribers to VoIP (Voice over Internet Protocol) telephone services may not be aware of limitations in accessing 911 during an emergency. VoIP is a telephone service that connects calls through the internet as a means of communicating with other phones. Voice over Internet Protocol means the phone has no fixed address and therefore the traditional 'location' feature of 911 are not available. The call is answered by a "third party operator service" where it is then transferred to a 911 call centre. 911 services may not be available from your VoIP during a power outage or an interruption to Internet services.
To ensure the least possible delay when using VoIP or a cell phone to make an emergency 9-1-1 call, be prepared to:
- Give your location: include address and town or city, to enable the call taker to either handle the information or transfer you to the correct 9-1-1 centre.
- Give your telephone number, including area code.
- Advise the nature of your emergency.
- Listen to the call taker's instructions - depending on the location and type of incident, you may be transferred.
- Stay on the line until advised otherwise by the call taker.

If you can insert the phrase "in order" before the infinitive, then it's an adverb of manner, like this,Originally Posted by jozi209
He went to the store in order to buy some food.
In order to buy some food, he went to the store.
If you can't insert the phrase "in order", then it's not an adverb of manner:
To be honest, I don't know.
I don't know, to be honest.
*In order to be honest, I don't know. (ungrammatical)

Without parity the Senior Men`s Tennis League of Broward County would have little reason to exist.
``We strive to give the men a chance to play against others with similar abilities,`` league president Joe Fishman said. ``We want every team to have a chance to win its division.``
The 1986-87 season is under way with 52 teams and about 1,100 members competing. Both are milestones. New teams have been formed, others have been revamped and several communities have expanded.
Lighthouse Point Tennis Center, Sea Garden Beach & Tennis Resort, Palm-Aire, Deerfield Beach Tennis Center, Deerfield Beach Century Village and Silver Thatch are all Northeast Broward teams that have returned for the 1986-87 season. One of the newest teams is Century Village in Pembroke Pines.
``We`re a new community and one of the best ways to build a tennis program is to get involved in as many tennis organizations as possible,`` said team captain Norman Morganstern. ``Some guys were bored playing against just themselves, so we joined. It`s fun to play outside competition. We`re very impressed with the way things are run.
``The bigger our community becomes, the more potential we have to get more men involved in playing tennis,`` Morganstern added. ``When we started our club here, we only had five guys. Now we`re up to about 50. Being involved in the league will only help us grow.``
While many of the players in several of the communities live in South Florida only during the winter, many of the league`s mainstays are Floridians. It has been a happy marriage so far. Since Fishman became president in 1984, the league has more than doubled.
``Anything can happen if you give people what they want,`` Fishman said.
Except for Broward`s southeastern corner, every part of the county is represented this year. And for the second consecutive year, the league is divided into five 55-and-over and two 65-and-over age divisions. A 70-and-over age division has been proposed for next season.

Chapter 4
After what seems like an eternity, Mole and Rat receive a response at Badger's door. Badger is cranky that someone has disturbed him at such a time of night, but when he sees that it is Rat and Mole, his tone changes to friendly, and he lets them in quickly. He brings them before a warm fire and gives them supper. Badger's home is one of many tunnels and halls and passageways, mysterious and exciting. Badger even attends to Mole's hurt shin, bandaging it up properly.
After the three animals eat, they sit before the fire, and Badger asks for news of the River, especially about Toad. Rat reveals that Toad has taken to driving motor cars, crashing one after another, insisting always on driving himself rather than hiring a driver. Toad has owned seven motor cars in succession...
