Genetically modified organisms include microbes used in biotechnology that possess enzymes promoting antibiotic resistance. This could be a problem given the rise of antibiotic-resistant organisms. However, these engineered microorganisms do not pose a risk to public health. What do you think prevents them from spreading antibiotic resistance to pathogens outside the laboratory

Answers

Answer:

What prevents these microorganisms from spreading resistance outside the laboratory is that they are modified to not survive outside the laboratory environment.

Explanation:

Antibiotic resistant microorganisms are very dangerous and unfavorable, as they leave living beings completely completely defenseless to their attacks. However, there are microorganisms that have been modified in the laboratory, as shown in the question above, and do not present any risk to living beings, even if they develop resistance. This is because the modification that these microorganisms received makes them not survive the environmental conditions outside the laboratory, which causes them to die if they leave the laboratory.

Choose the phase of meiosis in column 2 that best matches each event in column 1. - one haploid set of replicated chromosomes at each spindle pole - genetic recombination events take place - shortest stage - aligning of bivalents in the center of a spindle - one haploid set of unreplicated chromosomes at each spindle pole - aligning of monovalents in the center of a spindle - separation of homologous chromosomes - separation of sister chromatids A. telophase II B. anaphase I C. metaphase I D. prophase II E. anaphase II F. telophase I G. metaphase II H. prophase I

Answers

Answer:

H. prophase I → genetic recombination events take place

C. metaphase I → aligning of bivalents in the center of a spindle

B. anaphase I → separation of homologous chromosomes

F. telophase I → one haploid set of replicated chromosomes at each spindle pole

D. prophase II → shortest stage

G. metaphase II → aligning of monovalents in the center of a spindle

E. anaphase II → separation of sister chromatids

A. telophase II → one haploid set of unreplicated chromosomes at each spindle pole

Explanation:

Through the process of Meiosis, a diploid germ cell (2n) divides and originates four daughter cells with a haploid chromosome number (n). Each daughter cell has half of the chromosomes of the original one. Meiosis is completed in two phases. During the first phase, and after replication, occurs the chromosome´s reduction division. During the second phase, the cell suffers a new, not reductive division.

1. In the first phase, Meiosis I:

Prophase I: Chromosomes condensate and became visible. Occurs crossing-over between homologous chromosomes. Crossin-over makes the daughter cells to be genetically different from the original one. Metaphase I: The pairs of homologous chromosomes randomly align in the equatorial plane. Anaphase I: occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. Telophase I: Each of the homologous pairs chromosomes is already in the corresponding poles, and the nuclear membrane forms again in each pole.

2. In the second phase, Meiosis II:

Prophase II: Chromosomes condensate again and become visible. Metaphase II: Chromosomes join the spindle apparatus and migrate to the equatorial plane, where they randomly line up. Sister chromatids are holden together until they reach the Anaphase. Anaphase II: Centromeres divide, chromatids get separated, and each of them goes forward an opposite cellular pole. Telophase II: Once in the poles, the chromosomes became lax again, and cytokinesis occurs.

The relationships among different orders of millipedes are shown in the cladogram. Based on this cladogram, which statement best describes relationships among millipede orders? Stemmiulida is more closely related to Merocheta than Penicillata is to Merocheta. Spirostreptida is more closely related to Glomerida than Sphaerotheriida is to Glomerida. Polyzoniida is more closely related to Glomeridesmida than Sphaerotheriida is to Glomeridesmida. Merocheta is more closely related to Glomeridesmida than Glomerida is to Glomeridesmida.

Answers

Answer: Stemmiulida is more closely related to Merocheta than Penicillata is to Merocheta

Explanation:

Your question isn't complete as you didn't attach the picture needed to solve the question but I searched online and got the picture which is attached below.

Therefore, based on this cladogram, the statement best describes relationships among millipede orders is that Stemmiulida is more closely related to Merocheta than Penicillata is to Merocheta.

Therefore, the correct option is A

Farmer toon soon wanted to start breeding his plants so that they are resistant to disease while producing more fruit per plant.Which plants should the farmers cross to get the desired (wanted) combination of traits

Answers

Answer:

cultivated plant variety with its wild type variety.

Explanation:

The farmer cross the cultivated plant variety to its wild type which has the characteristics of resistance against diseases. Due to crossing, the offspring produce having resistance against that disease as well as producing high yield. This type of crossing is known as artificial selection in which humans cross two organisms to get the desired characteristics in their offspring so to get a plant with resistance against disease we cross cultivated plant variety to its wild type.

How do you think Madison's and Jefferson's views were used to justify secession and the Civil War about 60 years later?

Answers

Answer:

dameema  

Explanation:

Madison and Jefferson were both strong advocates for states' rights and believed that the federal government should have limited powers.

Who were Madison and Jefferson?

Madison and Jefferson were both strong advocates for states' rights and believed that the federal government should have limited powers. Their views were used by pro-slavery advocates in the South to justify secession and the Civil War by claiming that the federal government was encroaching upon states' rights and attempting to restrict the institution of slavery.

These advocates argued that the Constitution was a compact between independent states and that the federal government was created only to perform certain limited functions. They claimed that the federal government had overstepped its bounds and was attempting to impose its will on the South, which violated the principles of states' rights and self-government.

Although Madison and Jefferson did not explicitly support secession or the institution of slavery, their ideas were appropriated and distorted by pro-slavery advocates to advance their own agenda. The use of their views in this context highlights the complex and sometimes conflicting ways in which historical ideas and figures can be interpreted and deployed for political purposes.
