Mrs. Jones blood typing results showed agglutination with the plasma containing anti - B antibodies only. What is her blood type
MakcuM [25]

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.

Give an example of warning coloration used in<br> nature.
iren2701 [21]

Answer:

Warning coloration (aposematism) is effectively the "opposite" of camouflage and a special case of advertising. Its function is to make the animal, for example, a wasp or a coral snake, highly conspicuous to potential predators, so that it is noticed, remembered, and then avoided.

Hope this helped you.

30. One cause of muscle soreness is
xenn [34]

Answer:

c. lactic acid fermentation

Explanation:

If we did alcoholic fermentation, working out would make us feel drunk, not sore. This is only done by yeasts (a type of fungus) and bacteria. Glycolysis is simply an anaerobic process that occurs with fermentation and also regular aerobic respiration. It doesn't cause any soreness on its own. The Krebs cycle is the second major part to cellular respiration; it produces 6 NADH's, 2 FADH2's, 4 CO2's and 2 ATP; it's not involved in creating any soreness, as cell respiration does not create soreness. That leaves lactic acid fermentation, which we, bacteria, yeasts, and other organisms do. This is what we do when we run out of ample oxygen while doing some strenuous activity. Glycolysis is done with it. Glycolysis, however, relies on NAD+ to create ATP we need to maintain the same level of activity, lactic acid is produced as it accepts the 2 electrons and [H+] NAD+  should accept.
