Why do scientists prefer to use embryonic stem cells instead of adult skin cells?
-
Because embryonic cells are more abundant.
-
Because adult skin cells cannot be made into stem cells.
-
Because embryonic cells may carry diseases.
-
Because the use of adult skin cells could have abnormalities.
Correct Answer
A. Because the use of adult skin cells could have abnormalities.Explanation
Scientists prefer to use embryonic stem cells instead of adult skin cells because the use of adult skin cells could have abnormalities. This is because adult skin cells have already undergone differentiation and are more specialized, making it difficult to reprogram them into pluripotent stem cells. On the other hand, embryonic stem cells are undifferentiated and have the potential to develop into any type of cell in the body. Therefore, they are considered more versatile and suitable for various research and therapeutic applications.Rate this question:

Some of the earliest uses of cloning were developed for
-
Animal livestock
-
Farming and agriculture
-
Pharmacology
-
Teaching
Correct Answer
A. Farming and agricultureExplanation
Cloning technology was initially developed for farming and agriculture purposes. This allowed scientists to produce genetically identical copies of high-quality livestock, such as cows and sheep, which had desirable traits such as increased milk production or disease resistance. Cloning also proved beneficial in agriculture by enabling the production of identical plants with desirable traits, such as disease resistance or higher crop yield. This advancement in cloning technology revolutionized the farming and agriculture industries, offering a more efficient and effective way to produce superior livestock and crops.Rate this question:

The first four legged animal o be successfully cloned was...
-
Dolly the sheep
-
Snuffy the dog
-
Elsie the cow
-
Bif the cat
Correct Answer
A. Dolly the sheepExplanation
Dolly the sheep was the first four-legged animal to be successfully cloned. This breakthrough in cloning technology occurred in 1996 when scientists at the Roslin Institute in Scotland successfully cloned a sheep using a technique called somatic cell nuclear transfer. Dolly's birth was significant as it demonstrated that it was possible to clone a mammal from an adult somatic cell, challenging the belief that only embryos could be cloned. Dolly's cloning paved the way for further advancements in cloning technology and sparked debates about the ethical implications of cloning.Rate this question:

What is the future of cloning?
-
Extending cloning to humans
-
Spare boy parts can be made for individual people
-
Saving endangered species
-
All of the above
Correct Answer
A. All of the aboveExplanation
The future of cloning includes extending it to humans, where spare body parts can be created for individuals in need. Additionally, cloning can also be used as a means to save endangered species by creating replicas of them. Therefore, the correct answer is "all of the above" as it encompasses the potential advancements and applications of cloning technology.Rate this question:

Genetic engineering is used to...
-
Make machines work more efficiently
-
Make people's lives easier
-
Get a desired characteristic
-
None of the above
Correct Answer
A. Get a desired characteristicExplanation
Genetic engineering is a scientific technique that involves altering the DNA of an organism. It is used to introduce specific traits or characteristics into an organism's genetic makeup that are not naturally present. These desired characteristics can include traits such as disease resistance, increased crop yield, or improved nutritional content. By manipulating the genes, genetic engineering allows scientists to create organisms with specific traits that can be beneficial in various fields such as agriculture, medicine, and industry.Rate this question:

Genetic engineering could be used to create...
-
Pest resistant plants
-
Cows that produce more milk
-
A child without a genetically transmitted condition
-
All of the above
Correct Answer
A. All of the aboveExplanation
Genetic engineering has the potential to create pest resistant plants by introducing genes that make them resistant to pests. It can also be used to create cows that produce more milk by modifying their genetic makeup to increase milk production. Additionally, genetic engineering can be employed to prevent genetically transmitted conditions in children by altering or removing the genes responsible for these conditions. Therefore, the correct answer is "all of the above" as genetic engineering can be utilized for all these purposes.Rate this question:

T/F: People are reluctant to consume genetically engineered foods because...
-
They do not taste good
-
Long term health risks are unknown
-
They are more expensive
-
They have been proven very dangerous
Correct Answer
A. Long term health risks are unknownExplanation
People are reluctant to consume genetically engineered foods because long term health risks are unknown. This is because there is limited research and understanding of the potential long-term effects of consuming genetically modified organisms (GMOs) on human health. Many individuals are concerned about the potential risks and prefer to err on the side of caution when it comes to their health and well-being. The lack of concrete evidence regarding the safety of GMOs in the long run contributes to the reluctance of people to consume genetically engineered foods.Rate this question:

Genetics overall involve the study and manipulation of...
-
The brain
-
RNA
-
DNA
-
The heart
Correct Answer
A. DNAExplanation
Genetics involves the study and manipulation of DNA. DNA carries the genetic information that determines the characteristics and traits of living organisms. It is composed of nucleotides and contains the instructions for building and maintaining an organism. Through the study of DNA, scientists can understand how traits are inherited and can manipulate genes to study their function or potentially modify them for various purposes such as medical treatments or agricultural improvements. Therefore, DNA is the correct answer as it is the fundamental molecule that genetics focuses on.Rate this question:

There is a lot of ethic controversies with which topic of genetics?
-
Stem cell research
-
Cloning
-
Genetic engineering
-
All of the above
Correct Answer
A. All of the aboveExplanation
The correct answer is "all of the above" because all three topics - stem cell research, cloning, and genetic engineering - have been the subject of ethical controversies in the field of genetics. Stem cell research involves the use of human embryos, which raises ethical concerns for some people. Cloning raises questions about the ethics of creating identical copies of organisms. Genetic engineering involves manipulating the genes of organisms, which raises concerns about unintended consequences and playing with nature. Therefore, all three topics are associated with ethical controversies in genetics.Rate this question:
