enzymes are part of the ( mechanical = 1)( chemical =2 ) digestion process. the function is to break down ( vitamins =1 ) ( atoms = 2) (macro molecules = 3 ). amylase is a digestive enzyme secreted ( in the small intestine and by the liver = 1) ( in the stomach and by the gallbladder =2 ) ( in the mouth adn by the pancreas = 3) and is responsible for breaking down ( proteins =1 ) ( nucleic acids = 2 ( starch = 3) ( lipids = 3

The construction of phylogenetic trees is a mapping out the proposed divisions and common ancestors of all living species. traditionally, these trees have been built using morphological data, such as appearance and embryology. recently, it has been possible to construct these trees using molecular data. phylogenetic trees based on different types of information agree with each: that there is strong evidence of a real underlying common descent. this phylogenic tree is composed based on molecular data (rrna). what statements can we infer are true about the organisms throughout the tree? because the tree is rooted, all branches share a common ancestor. all organisms have some sort of cellular structure/organization. all eukaryotes evolved from bacteria. since the organisms contain rna, they share the same dna. if the organisms contain rna, the share the same four nitrogen bases.

Type the correct answer in each box. use numerals instead of words. if necessary, use / for the fraction bar. the following chemical equation shows the combustion of ethane. balance the equation by filling in the coefficients. c2h6 + o2 → co2 + h2o

Looking at this image, what relationship can be drawn from it? the lower the degree of latitude, the lower the degree of temperature there is no relationship between latitude and temperature the higher the degree of latitude, the higher the degree of temperature the lower the degree of latitude, the higher the degree of temperature
