A scientist focusing on the evolutionary history of specific significant traits is engaged in cladistics.
Cladistics is a method of biological classification in which organisms (plants and animals) are grouped based upon shared significant derived characteristics (synapomorphies). Cladistics identifies various significant shared traits that can be traced to the most recent common ancestor of a group of species and that are not found in more distant groups and ancestors. Cladistics uses various anatomical, molecular and genetic characteristics of organisms.
Answer:
Cofilin binds to older actin filaments
Explanation:
Microfilaments (also called actin filaments) are a class of protein filament common to all eukaryotic cells, which consist of two strands of subunits of the protein actin. Microfilaments form part of the cell's cytoskeleton and interact with the protein myosin in order to allow the movement of the cell. Within the cell, actin may show two different forms: monomeric G-actin and polymeric F-actin filaments. Microfilaments provide shape to the cell because these filaments can depolymerize (disassemble) and polymerize (assembly) quickly, thereby allowing the cell to change its shape. During the polymerization process, the ATP that is bound to G-actin is hydrolyzed to ADP, which is bound to F-actin. ATP-actin subunits are present at the barbed ends of the filaments, and cleavage of the ATP molecules produces highly stable filaments bound to ADP. In consequence, it is expected that cofilin binds preferentially to highly stable (older) filaments ADP-actin filaments instead of ATP-actin filaments.
Deductive reasoning.
Deductive reasoning is a type of reasoning where a general fact is broken down into a more specific case to make an inference. This general fact can be a broad branch of knowledge then gets into its parts that may comprise this broad knowledge.
Answer:
Grass
Explanation:
Grass is the producer in the given food chain.
Note : -
Grasses are green plants which synthesize food ( carbohydrate ) in presence of sun light in the process of photosynthesis. That's why grass is called producers.
