Answer:
I would predict that the the following generation will have a large amount of pups that are eaten by the sharks.
This question seems like its asking about natural selection. 
"Natural selection is the process when organisms better adapted to their environment tend to survive and produce more offspring"
Explanation:
 If the marine biologist did not give the pups medicine in the first generation, the pups that were less fit or not adaptive to the enviroment to naturally survive the infections would have died. This would have prevented these pups from passing on their genes. 
The next generation would consists of pups that are more immune to the sickness or more fit for their enviroment and might experiece less pups to die. 
 
        
             
        
        
        
Answer:
The correct answer is - Roots allow plants to obtain water and nutrients, while shoots allow plants to obtain gases and sunlight.
Explanation:
Plants have two major parts of the body normally root and shoot. roots are the parts of plants that usually present under the ground and absorbed the essential nutrients and minerals for the life of the plant. Water is also absorbed by the roots that are used in the various processes such as transpiration and photosynthesis.
The shoot includes stem and leaves and responsible for the exchange of gases, particularly taking in carbon dioxide and removes oxygen with help of stomata. These also absorbs sunlight with help of chlorophyll present on the leaves.
 
        
             
        
        
        
It absorbs and processes nutrients from food the same way I leaf does with sunlight

Answer:
The correct answer is option b. "20 H1, 40 H2A".
Explanation:
Chromatin is a complex that protects and condenses the genetic material comprised of DNA and proteins. When chromatin is in the form of a 30 nm fibril, nucleosomes have a regular positioning along the DNA. This means that each nucleosome is associated with a single H1 molecule. Therefore a chromatin containing 20 nucleosomes will have 20 copies of H1 and 40 copies of H2A, because each nucleosome has 2 copies of the core histone H2A.
