<h2>(Answer 1 points 3)</h2><h2>A. Taxon</h2><h3>3. the categories used in classifying organisms.</h3><h2>Explanation:</h2>
In other words, we can also say that taxon is also known as a taxonomic group of any rank, such as a species, family, or class. It is a group of one or more than one different populations of an organism or the organisms viewed by taxonomists to make a system. These are the rules for naming new animals.
<h2>(Answer 2 points 3)</h2><h2>B. Taxonomy</h2><h3>1. the science of the classification of organisms.</h3><h2>Explanation:</h2>
A taxonomy is said to be a scheme of classification or in other words, we can also define the term taxonomy as the branch of science involved with classification, especially of organisms, systematics. Organisms are grouped together. This science of gives name, describe and classify the organisms including all the plants, animals and the microorganisms of the world.
<h2>(Answer 3 points 3)</h2><h2>C. Family</h2><h3>4. A taxonomic category containing a group of similar genera.</h3><h2>Explanation:</h2>
Family is the one that has been classified between order and genus. A family is also divided into the subfamilies. It is one of the eight main and important taxonomic levels. It is a primary taxonomic category of organisms ranking. This category comes on the sixth number of all the categories lies in a taxonomic group.
<h2>(Answer 4 points 3)</h2><h2>D. domain</h2><h3>2. The largest taxonomic category.</h3><h2>Explanation:</h2>
In the three-domain system of taxonomy, if we talk about the domain then we would define it as the superkingdom or empire. It can also be said to be as it is the highest taxonomic rank of organisms. It is a taxonomic category above the kingdom level. There are three domain such as Bacteria, Archean, and Eukarya, which we can say are the major categories of life.
Answer:
For both actin and microtubule polymerization, nucleotide hydrolysis is important for decreasing the binding strength between subunits on filaments.
Explanation:
Cytoskeletal filaments are common to eucaryotic cells and are impotartant to the spatial organization of cells. Intermediate filaments provide mechanical strength and resistance to shear stress. Microtubules determine the positions of membrane-enclosed organelles and direct intracellular transport. Actin filaments determine the shape of the cell's surface and are necessary for whole-cell locomotion. A large number of accessory proteins are present that link the filaments to other cell components, as well as to each other. Accessory proteins are essential for the assembly of the cytoskeletal filaments in particular locations, and it includes the motor proteins that either move organelles along the filaments or move the filaments themselves.
Actin filaments and microtubules are assembled with expenditure of energy i.e the ATP/GTP tightly bound to actin/tubulin is irreversibly hydrolyzed to ADP/GTP during the assembly process, and liberation of Pi in the medium occurs subsequent to the incorporation of subunits in the polymer. Pi release acts as a switch, causing the destabilization of protein-protein interactions in the polymer, therefore regulating the dynamics of these fibres. The progress is made in four areas: the chemistry of the NTPase reaction; the structure of the intermediates in nucleotide hydrolysis and the nature of the conformational switch; the regulation of parameters involved in dynamic instability of microtubules; and the possible involvement of nucleotide hydrolysis in the macroscopic organization of these polymers in highly concentrated solutions, compared with the simple case of a equilibrium polymers.
