When the cell grows, prepares for division and divides into two new cells.
Answers
The cell cycle is the series of events that occur in a cell leading to its division and duplication of its DNA to produce two daughter cells.
The cycle consists of two main stages: interphase (G1, S, G2) and the mitotic phase (M). In interphase, the cell grows, replicates its DNA, and prepares for division. During the mitotic phase, the cell physically divides into two identical daughter cells through processes such as chromosome condensation, nuclear envelope breakdown, and formation of the cleavage furrow. This is regulated by checkpoints that ensure proper DNA replication and segregation before cell division can occur. The cell cycle is essential for the growth and repair of tissues and organisms.

Discuss why myrtle rust is a fungal disease of concern in New Zealand.
Describe why the fungus attacks the parts of the tree that it does.
Explain what someone should do if they find that one of their trees has a myrtle rust infection.
Discuss how myrtle rust infecting manuka trees can affect both beekeepers.
Answers
The fungus attacks the leaves, shoots, and flowers of the trees, causing distinctive yellow-orange powdery pustules on the undersides of the leaves and eventual defoliation of the plant. The fungus primarily spreads through windborne spores, which can travel long distances and infect susceptible plants throughout the country. The fungus can survive on dead plant material, making it difficult to eradicate once established in an area.
If someone finds that one of their trees has a myrtle rust infection, they should report it immediately to the Ministry for Primary Industries (MPI) or their local biosecurity agency. It is crucial to prevent the spread of the disease by avoiding movement of infected plant material or soil, cleaning gardening tools and machinery after use, and following other biosecurity guidelines.
Myrtle rust infecting manuka trees can affect both beekeepers and honey production. Manuka honey is a valuable and unique product in New Zealand, and the manuka tree is a critical source of nectar for honeybees. The fungus can cause significant damage to manuka trees, reducing the amount and quality of nectar available for bees, which can affect honey production and beekeeper livelihoods. Additionally, myrtle rust infections can make the trees more susceptible to other pests and diseases, leading to further damage and economic losses. Overall, myrtle rust is a serious threat to New Zealand's environment, economy, and cultural heritage, and it requires ongoing efforts to prevent its spread and manage its impacts.
Biological treatments of hazardous waste involve ___________ hazardous substances.
A) using microorganisms to disperse
B) the genetic alteration of species suffering from
C) special organic chemical processing of
D) using plants, bacteria or fungi to absorb and detoxify
Answers
Biological treatments of hazardous waste involve using plants, bacteria, or fungi to absorb and detoxify hazardous substances. The correct option is D.
Biological treatments of hazardous waste involve the use of living organisms, such as plants, bacteria, or fungi, to absorb and detoxify hazardous substances. This approach is known as bioremediation and is aimed at reducing or eliminating the harmful effects of hazardous waste on the environment.
In bioremediation, specific plants, bacteria, or fungi are selected for their ability to metabolize or break down the hazardous substances present in the waste. These organisms can absorb or take up the contaminants from the soil, water, or air, and through various biochemical processes, transform them into less toxic or non-toxic forms. This helps in the natural degradation and removal of hazardous substances from the environment.
Plants used in bioremediation, known as phytoremediation, can uptake and store contaminants in their roots, stems, leaves, or other plant parts. Bacteria and fungi, on the other hand, can directly degrade or transform the hazardous substances through enzymatic reactions.
Biological treatments offer several advantages, including their potential for low-cost and environmentally friendly solutions. They can be used to remediate contaminated soil, water bodies, or air, and have been applied in various industrial and environmental cleanup scenarios.
It's important to note that the specific approach and choice of organisms for bioremediation depend on the nature of the hazardous waste and the environmental conditions present at the site.

How do species richness and species diversity differ?.
Answers
Species richness and species diversity differ in that species richness only describes the number of species present in a particular community or ecosystem.
Species richness and species diversity are two different measures of biodiversity in an ecosystem. Species richness refers to the total number of different species present in a particular community or ecosystem, while species diversity takes into account both the number of species and their relative abundance within the community. For example, consider two different ecosystems with the same number of species present.
In one ecosystem, one species is extremely abundant and makes up 90% of the community, while the other 10% of the community is made up of the remaining species. In the other ecosystem, all species are equally abundant, making up 10% of the community each. Both ecosystems have the same species richness, but the second ecosystem has a higher species diversity because there is a more even distribution of species.

Answers
Mendel made the conclusion from his observations on the garden pea plant that for each and every trait in a population, a pair of alleles are present i.e., dominant and recessive allele. Thus, the correct option is B.
What was Mendel's law?Mendel did his experiments on the garden pea plant (pisum sativum) in which he found that for all the characters two different alleles are present in a population in which one allele is dominant on the other which is recessive. The dominant allele is represented by capital letter and is present in all the generations whereas the recessive allele is represented by small letter and often skips the generation.
Thus, by compiling the results of pea plants, Mendel concluded that the characteristics could be divided into two forms- expressed and latent traits. He called these traits as dominant and recessive traits, respectively.

Guillain - Barré syndrome.
c.
myasthenia gravis.
d.
amyotrophic lateral sclerosis.
Answers
Ascending paralysis with no loss of sensation is characteristic of Guillain - Barré syndrome.
Ascending paralysis with no loss of sensation is a classic symptom of Guillain - Barré syndrome, which is an autoimmune disorder that affects the nerves. This condition causes the immune system to attack the nerves, resulting in weakness and numbness that typically starts in the legs and moves upward.
It is important to note that while multiple sclerosis, myasthenia gravis, and amyotrophic lateral sclerosis can all cause paralysis, they do not typically cause ascending paralysis with no loss of sensation as is seen in Guillain - Barré syndrome.
Guillain-Barré syndrome is a rare neurological disorder in which the body's immune system mistakenly attacks the peripheral nerves, leading to weakness, numbness, and tingling sensations. The paralysis usually begins in the legs and then ascends to affect the upper body and arms, but it does not involve loss of sensation.

Compare and contrast inhalation and exhalation in terms of what takes place between the lungs
and the diaphragm muscle.
Answers
During inhalation, the diaphragm contracts. As it contracts, the diaphragm moves downward, increasing the volume within the thoracic cavity. Due to this increased volume in the thoracic cavity, a negative pressure gradient is generated which causes air to flow from the environment into the lungs. The lungs expand as the alveoli of the lungs fill with air.
During exhalation, the diaphragm relaxes and rises into the thoracic cavity, decreasing the volume in the thoracic cavity. The decreased volume in the thoracic cavity results in an increased pressure which causes air to flow from the lungs out to the environment. At the same time, the lungs are elastic and act to help air flow out as the retract after being expanded.

B. They both undergo segregation during meiosis.
C. Their copy numbers in the cell decrease after meiosis, and increase during fertilization. D. They are both copied during the S phase of the cell cycle.
E. They both pair up with their homologues during prophase of mitosis
Answers
Answer:
Answer: C. Their copy numbers in the cell decrease after meiosis, and increase during fertilization.
Explanation: Chromosomes and genes share all of the characteristics listed except for C. Chromosomes undergo segregation during meiosis, which results in a decrease in their copy numbers in the cell. However, genes do not undergo segregation during meiosis, so their copy numbers in the cell do not decrease after meiosis. Instead, the copy numbers of genes increase during fertilization when the two haploid cells combine to form a diploid cell.
if a researcher developed a drug that prevented insertion of the sars-cov-2 spike protein into the endoplasmic reticulum, what effect would you predict from this drug?
Answers
If a drug was developed that prevented the insertion of the SARS-CoV-2 spike protein into the endoplasmic reticulum, it would likely inhibit the endosomal entry pathway for the virus. This pathway is essential for the virus to enter the host cell and initiate infection. Without this entry pathway, the virus would not be able to replicate and cause harm to the host.
What is a spike protein?
The spike protein is a key antigen of the virus and is responsible for its virulence, or ability to cause disease. By blocking the insertion of the spike protein into the endoplasmic reticulum, the drug could potentially reduce the severity of the infection and prevent the spread of the virus. This drug could be an important tool in the fight against COVID-19, as it could reduce the number of cases and potentially save lives.
If a researcher developed a drug that prevented the insertion of the SARS-CoV-2 spike protein into the endoplasmic reticulum, the following effects can be predicted:
1. Inhibition of endosomal entry pathway: By blocking the insertion of the spike protein, the drug would interfere with the virus's ability to enter host cells through the endosomal entry pathway, which is crucial for the infection process.
2. Reduction in antigen presentation: Since the spike protein acts as an antigen, preventing its insertion into the endoplasmic reticulum would lead to a decrease in antigen presentation. This, in turn, may affect the host's immune response against the virus.
3. Decreased virulence: Blocking the insertion of the spike protein would likely reduce the virulence of SARS-CoV-2, as the virus would be less successful in infecting host cells and spreading within the host organism.
In summary, a drug that prevents the insertion of the SARS-CoV-2 spike protein into the endoplasmic reticulum would likely inhibit the endosomal entry pathway, reduce antigen presentation, and decrease the virulence of the virus.

What is the primary structure of the peptide? Explain each piece of evidence given and the reasoning that led to your answer.
Answers
The primary structure of the peptide in question is Arg-Glu-Gly-Lys-Met-Phe. This structure can be deduced from the information given in the question.
Firstly, the reagents and their specificities indicate that each of the amino acids in the peptide are cleaved at different points. Trypsin cleaves Lys and Arg at the C-terminus, while S. aureus V8 protease cleaves Glu and Asp at the C-terminus. Additionally, Cyanogen bromide cleaves Met at the C-terminus, leaving two tripeptides, and finally Chymotrypsin cleaves Phe, Trp and Tyr at the N-terminus, leaving a dipeptide and a tetrapeptide with absorbance at 280nm.
When the peptide structure is drawn based on the cleavage sites, it becomes clear that the primary structure of the peptide is Arg-Glu-Gly-Lys-Met-Phe. This structure, therefore, best explains the observations made by the reagents and the absorbance data.
