(2018). halide-directed synthesis of square prismatic ag nanocrystals by the polyol method. chemistry of materials. (doi
A critical challenge in the fabrication of bottom-up plasmonic materials is achieving shape control of high-quality metal nanocrystals.
Using a modified polyol method, we create a unique anisotropic Ag nanocrystal shape. The controlled addition of Br- anions during the nucleation and growth process results in single-crystalline Ag square prism nanocrystals with two square facets and four rectangular facets, uniform size distributions, and a high yield (96%).
Br- acts as a reshaping agent in the formation of single-crystalline seed nanoparticles, which then direct anisotropic growth in the 100 direction. Optical absorption spectroscopy, which reveals the localized surface plasmon resonances of the square prisms, is used to monitor nanocrystal growth and shape development.
Electrodynamic simulations show that the high aspect ratio shape causes strong near-field enhancement, implying that these nanocrystals could be used as optical nanoantenna in plasmonic platforms such as surface-enhanced Raman spectroscopy sensors and optoelectronic junctions.

Draw an example carbon cycle, showing the atmosphere and at least 3 other major sinks/reservoirs Include biotic and abiotic components in your diagram. Show how carbon flows to and from all four of these locations, labeling the process that connects each. Include one example of how humans are connected to the carbon cycle.
The carbon cycle is the process by which carbon is exchanged between the atmosphere, land, oceans, and living organisms.
The atmosphere is a major reservoir of carbon in the form of carbon dioxide (CO2). The biotic components of the carbon cycle in the atmosphere include plants and algae, which absorb CO2 during photosynthesis to produce oxygen and organic compounds.
The oceans are another major reservoir of carbon, mostly in the form of dissolved CO2, bicarbonate ions, and carbonate minerals. The biotic components of the carbon cycle in the oceans include phytoplankton, which absorb CO2 during photosynthesis and transfer it to the ocean food web.
The land is another major reservoir of carbon, mostly in the form of soil organic matter, dead plant matter, and fossil fuels. The biotic components of the carbon cycle on land include plants, which absorb CO2 during photosynthesis, and decomposers, which break down dead plant matter and transfer carbon to the soil.
The process of photosynthesis and respiration connect the atmosphere, land and oceans. During photosynthesis, plants and algae absorb CO2 from the atmosphere, convert it into organic compounds, and release oxygen. During respiration, plants, algae, and other organisms use these organic compounds to produce energy, releasing CO2 back into the atmosphere.
Humans are connected to the carbon cycle in many ways. For example, the burning of fossil fuels, deforestation, and land use change all release large amounts of carbon into the atmosphere. These activities contribute to the increase of CO2 in the atmosphere which causes climate change.
In summary, the carbon cycle is the exchange of carbon between the atmosphere, land, oceans, and living organisms. The biotic and abiotic components of the carbon cycle are connected by the process of photosynthesis and respiration. Human activities such as burning fossil fuels, deforestation and land use change have significant impact on the carbon cycle and the increase of CO2 in the atmosphere.

Meiosis review : Match the terms correctly.
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
What is Mitosis and Miosis?
Cell division always involves a complex set of stages that are carefully choreographed and highly regulated. While mitosis and meiosis relate to two distinct processes of nuclear division, cytokinesis describes the division of a cell's cytoplasm.
The original nucleus divides into two identical nuclei during mitosis. Contrarily, meiosis produces four nuclei, each of which contains half as many chromosomes as the parent cell. Only the gametes, or cells that develop into sex, the egg and the sperm, go through meiosis in animals.
Number of chromosomes in daughter cells: The two daughter cells that emerge from mitosis are perfect replicas of the parent cell. With 30 chromosomes, each daughter cell will have 30. Each cell (i.e., gamete) would have 15 chromosomes by the conclusion of meiosis II, which is half of the original number.
Purpose and function :Mitosis aims to create daughter cells that are completely genetically similar to their mothers, with no extra or less chromosomes. On the other hand, meiosis serves a single function in the human body: the creation of gametes, or sexual cells such as sperm and eggs.
Some of Other Features are given below
Mitosis
All live cells go through a constant cell division process called mitosis.
Prophase, metaphase, anaphase, and telophase are the four fundamental phases of mitosis.
Asexual reproduction, or mitosis, is the mechanism used to divide cells.
Meiosis
Meiosis is the form of nuclear cell division that results in daughter cells that have one-half the chromosome numbers as the original cell.
In organisms that are diploid, the end result is cells that are haploid. Each daughter cell gets one complete set of chromosomes, i.e., one of each homologous pair of chromosomes.
The germ cells undergo meiosis to give rise to sperm and eggs.

summarize the process of dna replication including the enzymes involved and explain the significance
Primer binding, replication fork creation, elongation, and termination are the processes in DNA replication. DNA helicase, RNA primase, DNA polymerase, exonuclease, and DNA ligase are the enzymes involved in this process.
A single double-strand DNA copy is utilized to create two additional double-strand DNAs through the process of DNA replication. Replication goes through four basic stages: (i) replication fork development, (ii) primer binding, (iii) elongation, and termination. In the first step, the double helix of the DNA is opened and separated into two single strands of DNA with the help of the enzyme DNA helicase at a point called the origin. In the second step, the primer is generated with the help of the enzyme RNA primase. This primer binds to the lagging strands of the DNA. In the third step, the synthesis of DNA starts from 5' to 3' in a continuous direction in the leading strand with the help of the DNA polymerase enzyme. And in a discontinuous direction in the lagging strand with the help of RNA primase and Okazaki fragments. In the final step, exonuclease removes all the RNA primer, DNA ligase joins the Okazaki fragments, and telomerase synthesizes small segments or telomeres at the end of the DNA.

The founding number of individuals of a species can be small on an island, which leads to low genetic diversity, therefore, any genetic change that occurs will have a more pronounced effect on the population is the correct option.
Islands have a high rate of species exchange, this is not correct, because the isolation of species is a key factor in the divergence and fixation of traits .The following explain why trait divergence and fixation can occur more quickly on islands than in other geographical locations: A species' initial population on an island may be small. On islands, reproductive rates are lower. Species are isolated in an island .Reproductive rates tend to be lower on islands, which means that any genetic changes that occur will be passed on to fewer offspring and will therefore have a greater chance of becoming fixed in the population.

explain how the change of a single amino acid in hemoglobin leads to the aggregation of hemoglobin into long fibers. (review figures 5.14, 5.18, and 5.19)
The non-polar nature of the specific amino acid is what causes haemoglobin to change amino acids and aggregate into long fibres. Valine is used instead of glutamine in this scenario, which changes how the haemoglobin protein functions.
The sixth amino acid in regular haemoglobin is the acidic glutamic acid (Glu) (which has a negative charge on its side chain). Glu is substituted with valine (Val), a nonpolar amino acid that is extremely unlike Glu, in sickle-cell haemoglobin. The shape and thus the function of a protein are ultimately determined by its primary structure, which is its amino acid sequence. The haemoglobin molecules can combine and create lengthy fibres when Val is changed to Glu, which causes the protein to function improperly and the red blood cell to deform.
Due to a nucleotide error that results in the synthesis of aberrant beta-chains in haemoglobin S, the single amino acid substitution of valine for glutamic acid in the beta-chain causes sickle cell anaemia.

What is the Hardy-Weinberg equilibrium?
According to the Hardy-Weinberg principle, also known as the Hardy-Weinberg equilibrium, model, theorem, or rule, allele and genotype frequencies in a population would be stable from generation to generation in the absence of any extra evolutionary forces. The founder effect, inbreeding and outbreeding depression, mate selection, assortative mating, natural selection, sexual selection, mutation, gene flow, meiotic drive, and genetic hitchhiking are some of these variables.
In the early 20th century, Godfrey Hardy and Wilhelm Weinberg proposed the Hardy-Weinberg concept. They developed a technique for figuring out genotypes and allel frequencies in a population that is not evolving. Let's call them p and q, which stand for the allelic frequency, in the case of a gene with two possible alleles. The formula equals 1, as we are interested in frequencies and percentages.

The amount of water that each pump pumped up would not be monitored by a regulatory body, much less limited.For years, there was chaos in this society. A phenomenon known as "subsidence" wreaks havoc on infrastructure and compacts the soil, making it even harder for some aquifers to fill with water. Aquifers were gradually being drained lower and lower while the land above them sunk.To Learn more About Groundwater rights refer to:

Using at least one credible online source, research two evolutionary mechanisms of your choice. A mechanism is a process or technique for achieving a set result. Using the evidence from your research, explain how the mechanisms that you chose can impact the evolution of a species.
Two evolutionary mechanisms that can impact the evolution of a species are natural selection and genetic drift.
What is the evolution about?Natural selection is the process by which certain traits become more or less common in a population due to the fact that they confer an advantage or disadvantage in terms of survival and reproduction.
Genetic drift is another mechanism that can impact the evolution of a species. Genetic drift is the random fluctuation of allele frequencies in a population due to chance events.
In summary, both natural selection and genetic drift are mechanisms that can impact the evolution of a species. Natural selection is driven by the environment, and it causes certain traits to become more or less common in a population based on their survival and reproduction value. Genetic drift is a random process that can lead to the evolution of new species by altering the genetic makeup of a population.
