Answer:
the chicks and mouse would be losely conected because they have more of the same gentic material and fish and humans would havwe the same since they kind act like the same because The recent advances in developmental biology described  have established the central importance of a small number of highly conserved signal transduction pathways that mediate cell interactions crucial for animal physiology, reproduction, and development. It seems likely that many developmental toxicants might affect development by acting on those pathways. Application of the methods that have been so successful in elucidating them should now allow scientists to investigate that possibility and to determine the mechanisms by which developmental toxicants act. This chapter reviews the experimental approaches primarily responsible for the recent advances in knowledge about animal development and discusses how those approaches might be applied to developmental toxicology. Chapter 8 discusses how those approaches might lead to improved qualitative and quantitative risk assessment.
 
        
             
        
        
        
Answer:
Excessive amounts of nutrients can lead to more serious problems such as low levels of oxygen dissolved in the water. Severe algal growth blocks light that is needed for plants, such as seagrasses, to grow. When the algae and seagrass die, they decay

Answer:
The addition of a water molecule breaks a covalent bond between sugar monomers
Explanation:
The digestion of carbohydrates by enzymes is an example of a hydrolysis reaction. 
Carbohydrates are chains of monosaccharides. Hydrolysis involves the addition of a water molecule that cleaves the covalent bond between the molecules of sugar. 
The reverse reaction is a condensation reaction, the joining of sugar monomers to create a carbohydrate releases a molecule of water.
 
        
             
        
        
        
I’d say A is probably the correct answer , but if not A , then definitely B.
        
             
        
        
        
Look kid, this question has been up for 9 hours think its time to let it go......... hoped i helped. ✔verified✔
