Pls help... Two sharks have different parents. The two sharks have different proteins in their cells for the color on the tip of their fins. What can you say about the color on the tip of the two sharks' fins? a
The fins will be the same color since all sharks have the same fin color.
The fins will be the same color since all sharks have the same fin color.

b
The fins will be the same color because even with different proteins for fin color, the proteins can connect in the same way.
The fins will be the same color because even with different proteins for fin color, the proteins can connect in the same way.

c
The fins will be different colors since offspring from different parents will have different colored fins.
The fins will be different colors since offspring from different parents will have different colored fins.

d
The fins will be a different color since their proteins for fin color are different so the proteins will connect in different ways.
The fins will be a different color since their proteins for fin color are different so the proteins will connect in different ways.

answer; polycythemia is the correct answer;

i dont know this but ask your teacher for !

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
