Fixed cells that build new tissue end in (blast | cyte | clast). Cells that build fibers are (chondroblasts | osteoblasts | fibroblasts). Cells that maintain the tissue are (blast | cyte | clast). Cells that breakdown tissue are (blast | cyte | clast), such as bone breaking cells (osteoclasts | osteocytes | osteoblasts). Transient cells that manufacture antibodies are (plasma cells | mast cells | macrophage). (plasma cells | mast cells | macrophage) release histamines that trigger inflammation. Connective tissue (does | does not) have a blood supply and ( is | is not) innervated, with the exception of (cartilage | bone | adipose).

Complete the following statements about the functions of the digestive system. carbohydrates and fats are digested in secretes enzymes that aid in the digestion of carbohydrates, fats, and proteins. the secretes bile; bile is stored in undigested food is processed into feces in feces is then stored in until it is eliminated from the body via

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.

Which of these serves as a reference for comparison during a scientific investigation? a)outcome variable (dependent variable) b) test variable (independent variable) c)control group d)hypothesis
