Answer:
Mrs Jones Blood type= B type.
Safe transfusion from: B and O blood type.
Explanation:
In the given example, the anti-B antibodies are present in the donor plasma. Since anti-B antibodies react with B antigen present on the RBCs of blood, Mrs. Jones should have B antigen on the surface of her RBCs. The blood type with only B-antigen on the RBC's surface is blood type "B".
Hence, her blood type is "B" type which has B antigens that react with anti B antibodies of the donor plasma causing agglutination and hemolysis of RBCs.
She can get the blood of B and O blood types. Blood type O is a universal blood type as it does not have B or A antigens on the surface of its RBCs to initiate the agglutination.
The number of calories on a Halloween stash depends on the type of candies and the number of units of each. If the stash contains 5 units of each of these candies: chocolate bars, taffies, lollypops, and candy corn the total number of calories is 1,650.
Calories are the most common unit used to define the energy a specific food gives to your body. For example, an apple has 52 calories, while a banana has 89 calories.
Considering this, in a Halloween stash the calories depend on two factors:
- The types of candies or products
- The units of each one
Let's suppose there are 5 units of each of the following candies:
- Chocolate bars
- Taffies
- Lollypops
- Candy corn
Let's now calculate the calories
- Chocolate bars = 220 calories x 5 units = 1,100 calories
- Taffies = 20 calories x 5 units = 100 calories
- Lollypops = 83 calories x 5 units = 415 calories
- Candy corn = 7 calories x 5 = 35 calories
Add all the previous results:
1,100 + 100 + 415 + 35 = 1,650 calories in total

Some frogs are slimy because they are covered in a mucous coating. This coating helps them keep their skin moist which helps them breathe through their skin. The mucous often contains other chemicals, like antibacterial or anti fungals to help protect the frog.
