Answer:
Option D, West Nile virus fever/encephalitis
Explanation:
A re-emerging disease is one which after a long span of time has re-emerged again as the microbes causing such diseases have become resistant to the existing drugs.
Here tuberculosis , malaria and gonorrhea are the re-emerging disease as the microbes causing these diseases have become resistant to the available drugs and thus there is a need to produce medicines that could fight with the re-emerged multi drug resistant tuberculosis , Malaria and gonorrhea
Hence, option D is correct.
because it helps to move something from one side to another
Answer:
46 chromosomes Hope this helps in any way!

Explanation:
Water molecules are polar, meaning they have dipole polarities. The Hydrogen end is partially positive while the Oxygen end is partially negative. This is due to the fact that oxygen has a higher atomic mass and hence attracts most of the electron cloud of the molecule towards its end.
This property of water is very important because it is able to dissolve polar molecules while non-polar molecules do not dissolve. This is an important property in the body of organisms because, for example, water helps in the folding of proteins (by interacting with polar motifs of a protein) hence ensuring the protein maintains their functional structural forms.
Water also dissolves significant polar molecules that are utilized by the body, such as glucose, and helps in their transportation within the body. Water is also significant in the diffusion of hormones used in cell signaling, e.t.c.
Water is also able to dissociate ionic compounds, such as sodium chloride, that are important in the osmotic pressure homeostasis of cells.

Answer: Twenty five (25) of the chicks will be black.
Explanation: A cross between two heterozygous chicks (Bl/bl+) will produce four chicks; one will be Bl/Bl, two will be Bl/bl+ while one will be bl+/bl+.
A break down of the phenotypes is as follows:
Genotype ==> Phenotype
Bl/Bl ==> Black
Bl/bl+ ==> intermediate
bl+/bl+ ==> blue.
Since one out of four offsprings (1/4) is black, therefore if the two chicken produce 100 chicks, the number of chicks that will be black is 1/4 x 100 = 25.
