Around 1900, organizational and technological advancements in electricity sparked a new industrial revolution. The appearance of enterprises and cities was altered by electrical illumination and motors.
Businesses were able to expand their locations and increase their productivity thanks to centrally produced electricity. These accomplishments depended on the development of massive interconnected systems, most of which were monopolies controlled by corporations.
Before the war, the electricity business grew slowly, but in the 1920s it truly took off and played a significant role in the economic growth.
It offered factories a low-cost, effective source of power. It allowed for the simultaneous use of numerous sophisticated machines, paving the way for the development of mass production methods.
Because it provided the power required in consumers' homes for the new mass-produced goods, such as vacuum cleaners, refrigerators, and washing machines, electricity also contributed to the economic boom.

What does genetic modification do
Answers
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.

Gametes are the only haploid cells in the human body because they are the cells involved in sexual reproduction, which requires the combination of one set of chromosomes from each parent to form a new individual. The rest of the cells in the human body are diploid and do not participate in sexual reproduction.
Gametes, which are also known as sex cells, are the only haploid cells in the human body because they are the cells that are involved in sexual reproduction. Haploid cells have a single set of chromosomes, while diploid cells, which make up the majority of cells in the human body, have two sets of chromosomes.
During sexual reproduction, gametes from each parent combine to form a new individual. The gametes from each parent contribute one set of chromosomes to the offspring, so that the resulting diploid cells in the offspring have two sets of chromosomes, one set from each parent.

17. If most other species on Earth aren't monogamous, why are humans expected to be?
Answers
Of course, human cultural developments over thousands of years have shaped many variations on this basic theme. But the basic underlying logic remains the same. As evolutionary biologist Lynne Saxon put it, “monogamy is a compromise in which the winners are the offspring.”
That said, monogamy is by no means the rule across our entire species. In fact, a majority of societies around the world at least ALLOW men to have more than one wife. (A few allow women to have more than one husband.) The societies that allow for polygamy tend to be smaller than the ones where monogamy is the ideal, leading to a mistaken impression that our whole species is monogamous. But in fact, humans have devised a number of different sexual/reproductive strategies, across different cultural settings. Often it’s monogamy, for the simple reason that monogamy usually gives children the best chance of survival.

O a. Homologous structures
O b. Vestigial structures
O c.
Index fossils
O d. Analogous structures
Answers
Answer:
d. Analogous structures is not a good method in examining fossils anatomical features of living organisms.
Explanation:
Analogous structures are physical characteristics that are similar in different organisms due to convergent evolution, rather than being inherited from a common ancestor. While analogous structures can provide valuable information about the environment and adaptations of living organisms, they are not helpful in examining the fossils of ancient organisms because they do not reflect the evolutionary relationships between different species. Homologous structures, vestigial structures, and index fossils are all useful methods in examining fossil anatomy, as they can provide insights into the evolutionary relationships and characteristics of ancient organisms.

A.
0.0392
B.
0.0254
C.
0.045
Answers
The number of heterozygous carriers for a recessive genetic disorder in the Caucasian population of United States is 0.0392, option A.
How to find heterozygous carriers?In genetics, heterozygous means having inherited different versions (alleles) of a genomic marker from each biological parent. As a result, a person who is heterozygous for a genomic marker has two distinct versions of that marker.
Using the formula p + q = 1, p2 + 2pq + q2 = 1,
The allele frequency, p² = 1/2500 = 0.0004
√p² = √0.0004
p = 0.02
substituting p in the formula p + q = 1,
0.02 + q = 1,
q = 1 - 0.02 = 0.98
Frequency of heterozygous individuals = 2pq
2(0.02 x 0.98) = 0.0392
With the application of Weinberg theorem, p2 + 2pq + q2 = 1, the frequency allele of heterozygous carriers is 0.0392.
