During anaphase, sister chromatids are pulled to opposite poles by the spindle fibers in preparation for cleavage.
<span>The answer is false, as "elements", are singular atomic items, according to the "Table of Elements, each of which have their own unique atomic structure. They may be combined to form other substances or compounds. Elements would be the building block of other compounds.</span>
From the diagram above, I dont think that organisms of the same order share a stronger evolutionary relationship than organisms in the same phylum. This is because, after kingdoms, the subsequent categories of increasing specificity are: phylum, class, order, family, genus, and species.
<h3>Levels in taxonomic classification</h3>
At each sublevel in the taxonomic classification system, organisms become more similar.
Organisms that share similar physical features and genetic sequences tend to be more closely related than those that do not.
Scientists use a tool called a phylogenetic tree to show the evolutionary pathways and connections among living organisms.
<h3>Phylogenetic tree</h3>
A phylogenetic tree is a diagram used to reflect evolutionary relationships among organisms or groups of organisms
<h3>
Taxonomical classification</h3>
Taxonomy is the scientific study of naming, defining and classifying groups of living organisms based on shared characteristics. There are seven main taxonomic ranks:
- kingdom
- phylum ( in animals )or division ( in plants )
- class
- order
- family
- genus
- species.

Answer:
Explanation:
An antimicrobial agent is a natural or synthetic chemical that kills or inhibits the growth of microorganisms. Bacteria have a mechanism of transferring genomic material called <em>horizontal gene transfer</em><em>, the movement of genes between cells that are not direct descendants of one another</em>. Horizontal gene transfer allows cells to quickly acquire new characteristics and drives metabolic diversity. <u>One of the characteristics usually acquired is the resistance to antibiotics</u>.
Three mechanisms of genetic exchange are known in prokaryotes:
(1) transformation, in which free DNA released from one cell is taken up by another; (2) transduction, in which DNA transfer is mediated by a virus; and (3) conjugation, in which DNA transfer requires cell-to-cell contact and a conjugative plasmid in the donor cell.
Examples of genes transferred by transducing bacteriophages include multiple antibiotic resistance genes among strains of <em>Salmonella enterica </em>serovar <em>Typhimurium</em>, Shiga-like toxin genes in <em>Escherichia coli</em>, virulence factors in <em>Vibrio cholerae</em>, and genes encoding photosynthetic proteins in cyanobacteria.
Conjugative plasmids use a mechanism to transfer copies of themselves and the genes they encode, such as those for antibiotic resistance, to new host cells.
That would be B. From energy in photons.
Photons(from sunlight) give energy to electrons and “excite” them(sending them to a higher energy level). Electrons can then release this energy and excite other electrons in other chlorophyll molecules.
