Reil [10]

Answer:

Enhancer sequence.

Describe how the structures of proteins differ from the structures of carbohydrates (150 words)
Veronika [31]

well both are considered macromolecules. proteins are like big lego construction. each single piece gets pieced together to make a larger thing. each single piece is a monomer, and the larger construction is the polymer. the monomers are called amino acids and they get pieced together to form the polymer which is called a protein. the linkage that they use is an amide bond, and in biology it is usually called a peptide bond. carbohydrates can be singular monomers or polymer units. they are made of completely different compounds usually aldehydes or ketones. and they link together through different chemical linkages (acetal or ketal linkages for polymers, hemiacetal or hemiketal linkages for monomers). both can be large, 3D strucutres proteins are only functional as a large, 3D structure, while carbohydrates can be singular. (you might wanna word it differently for safety reason)

Which stimulus causes the roots of seedling to grow downard ?
Sergeu [11.5K]
Gravity
Plant roots always grow downward because specialized cells in root caps detect and respond to gravity. This is an example of a tropism. A tropism is a turning toward or away from a stimulus in the environment. Growing toward gravity is called geotropism.
