What would be the advantage(s) to having no chloroplasts in the cells of the spongy mesophyll?

Biology
1 answer:
Gwar [14]3 years ago
8 0
Well, first off the spongy mesophyll does have some chloroplasts, however they are located quite far from the surface of the leaf where most of the chloroplasts are. Therefore they don't get much light and don't contribute a lot to photosynthesis in the leaf. So why should the leaf waste the energy in making chloroplasts if there is not enough light to make them all efficient enough at photosynthesis?

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.

Is a gene that can be masked by dominant gene
ruslelena [56]

Answer:

i believe the answer is recessive.

Explanation:

a recessive gene can be expressed as rr instead of RR so if one does a punnet square it would show up to be Rr Rr Rr Rr, since R represents a  dominant  trait and r being being recessive, then the answer would be recessive. (sorry if it doesn't really make any sense)
