The key lesson learned from what has happened on the Easter Island is that the humans should live in balance with the nature and to use the natural resources responsibly. The Easter Island was inhabited by people until relatively recently, and they lived on the island for some time, but there's nothing left from them apart from numerous large heads made out of stone. The people that lived on the island died, and that happened because of their irresponsible way of using the natural resources and destroying the environment. The people that lived on the Easter Island managed to use and destroy all natural resources that were enabling their survival there, putting themselves in a situation where they didn't had anything to eat, nor having material to build boats and move on another place. They were tuck there, isolated, started to kill and eat each other until the last one of them was left and died. This is a very nice example and lesson for the humans in the present that they should be very careful with the nature and the natural resources because there's always a line that after it is crossed there's no coming back.

3.a An antibiotic is added to a large population of bacteria. Explain why not all bacteria die?
drek231 [11]

Answer: Antibiotic Resistant Mutation

Explanation: Not all of the bacteria die because there are individuals in the population that have an antibiotic resistant mutation, which causes them to be adapted to dealing with the antibiotic. There will be a large population of bacteria again because the ones with the mutation survive, reproduce, and pass the antibiotic resistance trait on.

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.
