Answer:
BO : OO
2 : 2
Explanation:
The results of mating between a man of blood group B heterozygous and a woman of blood group O produces children that will either have blood group B or O thus the probability of a child being either blood group B or O is 50%.
B O
O BO OO
O BO OO
Therefore genotype BO:OO
Phenotypes 2:2
Answer:
When red blood cells are in a hypertonic (higher concentration) solution, water flows out of the cell faster than it comes in. This results in crenation (shriveling) of the blood cell.

Answer:
'Genetically modified organisms' are organisms which have been altered genetically using genetic engineering. Genetically modified foods should be labelled since they allow the user to understand and to give them the choice to either eat them or not.
Explanation:
<u>Genetic engineering</u> is the process by which GMO are produced. Genetic engineering allows changes to be made at genetic level where new sequences of genes are introduced or deleted though techniques like <em>selective breeding</em> or <em>mutation breeding</em>.
Certain advantages and disadvantages of genetically modified food are stated below:
- In agriculture, crops are produced with better yield and taste.
- The crops are also made resistant to pests and insects.
- The seeds mature quickly.
- Few examples of GM foods are Golden rice, Flavr savr tomatoes, Bt cotton, etc.
Disadvantages of GMO:
- The new traits introduced can cause adverse <em>health reactions</em>.
- If these resistant varieties cross breed they might result in production of 'super weeds'.
Foods must be labelled since there might be health issues caused by them. The nutritional value of the food might be changed which should be observed if it is to be given to infants.
Mitochondria is the ''Power House'' of the cell.So it wouldnt have enough energy or power to survive.<span />
<span>I believe that the pattern that would be expected is both 14 N and 15 N, this is because the DNA was replicated in a conservative manner. Semi conservative replication would produce two copies that each contained one of the original strands and one new strand, while Conservative replication would leave the two original template DNA strands together in a double helix and would produce a copy composed of two new strands containing all of the new DNA base pairs</span>
