a. escape from freedom


b. the point/counterpoint phenomenon


c. the paradox of progress


d. modern society

Answers

This statement is characterized by the concept of the paradox of progress, as shown in option C..

What is the paradox of progress?It is a psychosocial concept.It's the term that describes bad results coming from good processors.

Progress is something good and desired by all communities. This is because all people want to progress in their social and individual lives. After all, the results of progress tend to be good, uplifting, and promote many good things.

However, there is a paradox where progress triggers poor results in elements that worked better in the past. An example of this can be seen in communities that progressed over time but emotionally regressed, keeping more people unhappy than before.

What does genetic modification do

Answers

Answer: Altering the genetic makeup of an organism.

Explanation:

Genetic modification is the process of altering the genetic makeup of an organism. This has been done indirectly for thousands of years by controlled, or selective, breeding of plants and animals. Modern biotechnology has made it easier and faster to target a specific gene for more-precise alteration of the organism through genetic engineering.

Hope Helps!

Answer:

Please read below:

Explanation:

Genetic modification, also known as genetic engineering or genetic manipulation, is the process of altering the genetic makeup of living organisms. This is done by manipulating the DNA of a living organism to create a desired outcome. It involves the introduction of foreign DNA into the organism, often from another species, in order to produce a desired trait. It is used in a wide range of applications, ranging from agriculture to medicine.

In agriculture, genetic modification is used to create crops with heightened resistance to pests, diseases, and adverse environmental conditions. It can also be used to increase crop yields, improve nutritional value, and reduce the use of pesticides and fertilizers.

In medicine, genetic modification is used to create vaccines, improve the efficacy of existing drugs, and create treatments for genetic diseases. It is also used to create healthier food and beverages, as well as to create new materials with improved properties.

In biotechnology, genetic modification is used to create new products for use in research and industry. These products are often used to study diseases, develop new drugs, and create bioplastics and biofuels.

Genetic modification has been controversial since its inception, as it has been used to create genetically modified organisms (GMOs). These organisms, created through genetic modification, have the potential to disrupt natural ecosystems, as well as to cause health problems in humans. For this reason, the use of GMOs is heavily regulated in many countries, and the public is often divided on the issue.

Overall, genetic modification has the potential to revolutionize the way we produce food, create medicines, and develop new products. However, it is important to remember the ethical and environmental considerations that must be taken into account when using this technology.

Which change would cause an increase in the size of a population?

Answers

Answer:It would be a migration  

Explanation:

The answer is migration. It is described as the movement of people from place to place and permanently at the new location.

Similarly, migration will be seen growing old in prosperous areas and boom it in bad ones. Most nations and areas experiencing populace lower accomplish that specifically because of natural change (the distinction among births and deaths), at the same time as areas which advantage populace accomplish that specifically because of extra-migration.

What are the effects of migration in the area?

 Migration has an effect on the populace of the 2 unique areas. It will increase the populace of the place (new place), in which human beings migrate on the lookout for process possibilities, and reduce the populace of the region in which human beings migrate from. The charge of populace boom is the charge of herbal boom blended with the results of migration. Thus the excessive charge of the herbal boom may be offset via way of means of a massive out-migration, and a low charge of the herbal boom may be countered via way of means of an excessive stage of in-migration.

Hence clear that migration change would cause an increase in the size of a population.

Sentence Arrange - Put the steps of DNA replication in order by writing a number in the space before each statement. _____Two new molecules of DNA are created. _____DNA polymerase attach the free-floating nucleotides to the exposed nitrogen bases. _____ Helicase begins to break the hydrogen bonds between nitrogen bases. _____DNA is stabilize by the enzyme topoimerase. _____DNA ligase mends Okazaki fragments.

Answers

Answer:

1. Helicase begins to break the hydrogen bonds between nitrogen bases.  

2. DNA is stabilized by the enzyme topoisomerase.

3.DNA polymerase attaches the free-floating nucleotides to the exposed nitrogen bases.  

4. DNA ligase mends Okazaki fragments.

5. Two new molecules of DNA are created.  

Explanation:

Replication is a cellular mechanism by which a DNA molecule is used as template to synthesize two identical DNA molecules, and then each daughter cell receives one DNA molecule during cell division. First, DNA unwinds at dynamic structures called replication forks: a helicase enzyme opens up the double helix of the DNA at the replication fork by breaking hydrogen bonds that hold complementary DNA strands together. Subsequently, a topoisomerase enzyme removes positive supercoils generated in front of the replication fork. In the next step, a DNA polymerase extends primers (i.e., short RNA sequences that serve as templates for the starting point of replication) by adding nucleotides to the 3' end of the growing strand. The replication continues in the 5' to 3' direction on the leading strand, while the strand of the DNA that runs 5' to 3' away from the replication fork (known as the lagging strand) must be synthesized in fragments called Okazaki fragments. Subsequently, a DNA ligase enzyme facilitates the joining of the Okazaki fragments by forming phosphodiester bonds between nucleotides, thereby resulting in a continuous lagging strand. Finally, replication ends when converging replication forks meet.

Answer: D. esophagus

Explanation: Because esophagus uses muscles and does not use enzymes to digest. It only transports food to the stomach and then goes further into the digestive system.

Why not your mouth because it uses the enzyme Amylase, which helps break down complex carbohydrates. It is also produced by the mouth. Lipase, which breaks down fats. Protease is a protein-breaking enzyme that breaks down proteins.

Select one:

1, increases the amount of greenhouse gases emitted into the atmosphere.

2, increases the rate of plant growth

3, increases levels of oxygen in the atmosphere.

4, reduces the amount of greenhouse gases emitted into the atmosphere.

Answers

Your requirement for electricity decreases as your home's energy efficiency rises, reducing your dependence on carbon-intensive power plants, and reducing the number of greenhouse gases emitted into the atmosphere, hence option 4 is correct.

How does electricity affect the greenhouse?

This lowers the plant's demand from your house, which helps the environment by lowering carbon dioxide emissions and lessening atmospheric emissions of greenhouse gases.

This rise is the result of the air's carbon and oxygen being combined to create CO2 during the burning of coal or oil.

Therefore, greenhouse gas concentrations have increased due to human activity, hence option 4 is correct.
