Explanation:

Translation terminates when the ribosome reaches a(n) codon, which is a codon not recognized by a tRNA: stop codon.

During the process of translation, the ribosome reads the mRNA sequence and synthesizes a polypeptide chain by linking amino acids together. Translation terminates when the ribosome encounters a specific codon called a stop codon. A stop codon is a nucleotide triplet within the mRNA sequence that does not code for any amino acid and does not have a corresponding tRNA molecule.

There are three stop codons: UAA, UAG, and UGA. When the ribosome reaches one of these stop codons, it signals the end of protein synthesis. At this point, the ribosome disassembles, releasing the completed polypeptide chain. The stop codon is recognized by release factors instead of tRNA molecules, and their presence prompts the termination of translation.

Therefore, the termination of translation occurs when the ribosome reaches a stop codon, which is a codon not recognized by a tRNA.

True. Neurotransmitter substances are recycled by neurons which helps their efficiency and speed of message sending.

Explanation:

Neurotransmitters are chemical messengers that allow neurons, the fundamental components of the nervous system, to communicate with one another.

Reuptake is the mechanism by which neurons recycle neurotransmitter chemicals to preserve the effectiveness and speed of this connection.

Some neurotransmitters are transported back up into the presynaptic neuron by transporters after they are released into the synaptic gap. The neuron uses its neurotransmitters more effectively thanks to the recycling mechanism, which also helps control the amount of neurotransmitters in the brain.

Additionally, it stops the development of extra neurotransmitters in the synaptic gap, which can cause toxicity or overstimulation.

The elevated PCB levels in the Last Frontier region may be attributed to a clandestine illegal dumping operation, where an unidentified entity has been disposing of PCB waste covertly. To test the hypothesis of an illegal dumping operation causing the observed increase in PCB levels, Conduct thorough sampling, identify potential dumping sites, investigate local industries, conduct stakeouts, trace the source, and take legal action and prevention measures.

The observation described above, which is detailed in the "PCB in the Last Frontier: A Case Study on the Scientific Method" file, can be explained by the presence of a clandestine illegal dumping operation in the Last Frontier region. This explanatory story suggests that an unidentified entity has been secretly disposing of PCB (polychlorinated biphenyl) waste in the area, leading to the elevated levels of PCBs detected in the environment.

1. Conduct thorough sampling: Collect samples from various locations in the Last Frontier region, including soil, water, and air samples, to quantify and compare the PCB levels. This will help establish a baseline for normal PCB concentrations in the area.

2. Identify potential dumping sites: Analyze the collected samples to identify hotspots of PCB contamination. Use geospatial mapping techniques and data analysis to identify areas with significantly higher PCB concentrations.

3. Investigate local industries: Examine nearby industrial facilities, waste disposal sites, and manufacturing plants to determine if any of them are involved in handling or producing PCBs. Gather information on their waste management practices and compliance with regulations.

4. Stakeout and surveillance: Set up surveillance equipment and conduct stakeouts in suspected areas to catch any illegal dumping activities in action. This may involve coordinating with law enforcement agencies and environmental protection organizations.

5. Trace the source: Analyze the collected PCB samples to determine the specific composition and characteristics of the PCBs. This information can help trace the origin of the PCBs and potentially identify the responsible party.

6. Legal action and prevention: If evidence of illegal dumping is discovered, report the findings to the appropriate authorities for legal action. Additionally, recommend stricter regulations, increased monitoring, and public awareness campaigns to prevent further illegal dumping incidents.

By following these steps, it is possible to investigate and test the hypothesis of an illegal dumping operation, ultimately providing evidence to support or refute the explanatory story behind the observed increase in PCB levels in the Last Frontier region.

Daphnia is an acuatic microarthropod which depends on the environment to perform its metabolic tasks. Arthropods are poikolotermic, which means their body temperature depends in the environment's temperature. Considering the above, it would be important to measure the following variables for some period fo time, let's say 90 days: 1) temperature, 2)salinity, 3)organic matter and 4) pH. Number of days is important, so we could give Daphnia time to acclimate to its new environment. We should measure at least to points, in the beginning, to measure the immediate to response to the abiotic change, and at the end, to measure the effect of the measured variable in Daphnias heart.

The design could comprise treatments with normal values of this variables where Daphnia lives, and with a couple of extreme values (both upper and lower extremes. For example, imagine Daphnia uses to live in lakes with mean temperature of 19 C, then this would be the control case for temperature and you could also use 14 C and 24 C, as the treatments to explore the effects of temperature variation. In any case the choice of values should be informed by literature. For example with ongoing climate change, you could use the projected rises in temperature to explore how Daphnia would perform in those cases. After performing the individual variable assays (I mean, temperature fluctuates, the rest of parameters are hold the same). It would be pretty informative to combine variables. Let's say, how could Daphni behave with warming and acidic pH. Another example, how could Daphnia behave with warming and organic matter enrichment/oligotrophy (poor concentration of nutrients). In this way you could asses more realistic scenarios, since nature has these and much more variables playing simultaneously. According to the problem, heart rate is the variable of interest (that is of our response variable), therefore we should measure heartrate in all the conditions mentioned above. As all organismis search to keep their metabolism/functions (that includes heart rate, among many other) with major changes, we should see some fluctuations in the begginng of the assay, but their will tend to stabilize if Daphnia is able to cope with the altered environment conditions.

As growth continues, the column of cells may divide or release offspring, in which case a complex gland is produced. While some glands, like the pancreas and salivary glands, constantly develop and divide to eventually become a very huge structure, many glands have a finite number of branches. The liver is an exception to the rule since there forms a reticulated compound gland; normally, the branches do not connect together.

The diagram illustrating meiosis is attached.

In sexually reproducing organisms, meiosis is a type of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm). Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent)

Meiosis is a type of cell division that results in the production of four gamete cells and a 50% reduction in the number of chromosomes in the parent cell. To produce egg and sperm cells for sexual reproduction, this process is necessary. Cells go through prophase, metaphase, anaphase, and telophase during each round of division.

Interphase: The DNA in the cell is copied resulting in two identical full sets of chromosomes.

Prophase: Each chromosome is composed of two sister chromatids containing identical genetic information.

Metaphase: The chromosome pairs line up next to each other along the center of the cell.

Anaphase: The meiotic spindle then separates the pair of chromosomes by pulling one chromosome to one pole and the other chromosome to the opposite pole of the cell.

Telophase and cytokinesis: The chromosomes complete their move to the opposite poles of the cell.

3. Histoplasma capsulatum is an opportunistic fungal pathogen that affects immunocompromised individuals, while Aspergillus fumigatus is a true fungal pathogen that affects both healthy and immunocompromised individuals.

Explanation:

Histoplasmosis is an oprtounista mycosis, that is to say that it increases in number in our organism occasionally generating infectious and non-protective pathology like the commensal flora.

Histoplasmosis respects American geographic limits and is because it lives in tropical and freshwater climates.

Histoplasmosis pathology is triggered if the person has a deficit in the immune response and if the risk of living or transiting the endemic area is corrected.

On the other hand, the aspergillus fungus is a fungus that enters the inhalation routes in a sporulated form and developed in the lungs, generating a high fatal risk, since it triggers inflammatory and necrotic symptoms in the lung, regardless of whether the person is immunodeficient or not. ... There were people who were shaved by this fungus and even selected hypersensitivity pictures, that is, the opposite of an immunodeficiency.

The Fungi of the Aspirgillus group do not discriminate against age, immune status, or other factors ... only inhalation of the spore is required to develop the pathological picture.

The two dorsally located columns are called the cor.p.ora cav.e.rnosa, and they are situated on the upper side of the p.e.ni.s. The c.o.r.p.o.r.a cavernosa are composed of spongy tissue that contains numerous blood vessels and sinuses. During s.e.x.u.a.l ar.o.u.sal, these blood vessels dilate, leading to an increase in blood flow into the corpora cavernosa. This influx of blood causes the p.e.n.i.s to become e.r.e.c.t.

The ventrally located column is called the co.r.pus spongiosum, and it runs along the underside of the p.e.n.i.s. The corpus s.p.o.ng.iosum also contains spongy tissue, but it has an additional important function.
