Like chromosomes, genes also come in pairs. Each of your parents has two copies of each of their genes, and each parent passes along just one copy to make up the genes you have. Genes that are passed on to you determine many of your traits, such as your hair color and skin color.
        
             
        
        
        
Hi there!

Plant cells contain a cell wall which causes them to be more rigid in structure, whereas animal cells only contain a cell membrane. 
In addition, plants contain chloroplasts, an organelle that allows the cells to undergo photosynthesis to produce energy. Animal cells, on the other hand, only contain mitochondria for cellular respiration.

Answer:
Ozone depletion greatly affects the hydrosphere. When ozone depletion occurs, thereis a 6 to 12%reduction in the marginal ice zone. This means that ice caps melt, and all of the polar bears drown. Also, solar UVB radiation has been found to cause damage to early developmental stages of fish, shrimp, crab, and plankton.
