|
The food and drug administration says a genetically engineered product is safe as long as it is substantially equivalent to the non-engineered product. What does that mean? |
Regardless of the actual genes, the engineered product appears, works or tastes like the natural product. |
|
|
Assuming they could both work, what is the difference in the outcome of somatic versus germ-line gene therapy? |
Somatic treats an individual |
|
|
Dairy products are generally nutritious but most human adults cannot digest them. This is because |

|
Which is the best description of the light reaction of photosynthesis? |
Chlorophyll absorbs solar energy and shoots off an electron, which is transferred through a series of compounds |
|
|
What is therapeutic cloning? |
A nucleus from a healthy cell is taken from a patient and injected |
|
|
The first published study of stem cells being successfully used to produce human tissue was in 2001. What type of cell did the stem cells make? |
Blood cells |
|
|
Why does the vast majority of scientists accept evolution as a fact of nature? |
There is a century's worth of data |
|
|
Which of the following statements about germ-line and somatic gene therapy is not true? |
Both gene therapies are getting increasingly routine |
|
|
How has genetic engineering helped in the treatment of diabetes in humans? |
Bacteria have been engineered to produce large quantities of human insulin, necessary for the treatment of diabetes |
|
|
What are the xylem and phloem? |
The vessels of the circulatory system of a plant |
|
|
Why is the ability to digest lactose in adults most prevalent in Northern Europe, North America, and Australia? |
Many people in these areas are descendants of the first dairy farms |
|
|
Plants and animals both need energy to live, but what's different about that energy? |
Plants and animals use entirely different types of energy. |
|
|
Natural selection works to improve the fitness or organisms by making them better adapt to their environment. What do scientists mean by fitness in this context? |
The most fit organism passes |
|
|
How does genetic screening of embryos lead to skewed sex ratios in some countries? |
Most commonly, in countries where boys are seen as more valuable |
|
|
What is the general procedure for carrying out somatic gene therapy? |
A properly functioning version of the dysfunctional gene |
|
|
Where did the pesticide Bt originally come from and what does it do? |
Its from bacteria species and it kills insects. |
|
|
Why are scientists interested in genetically engineered crops? |
Sometimes to enhance nutritional value. |
|
|
How could the availability of genetic screening and then therapies lead to a society of genetic "haves" and "have nots"? |
The people who could afford technology could get their defective genes fixed. |
|
|
Humans have been selecting for beneficial or desirable traits in crops and domesticated animals for a long time. What's the different about doing that through modern genetic engineering? |
Nothing really. Modern genetic en is just much faster. |
|
|
When A small subset of a larger population gets separated into a different environment from the main population, which of the following is likely to occurs? |
The new population will have a different set of traits |
|
|
If one species is split into two populations in two different places, natural selection may drive them to become two different species. How? |
They are isolated and adapting to two differ environments. |
|
|
What is it called when a particular envir condition results in a populations characteristics changing over time in order to better deal with it? |
Adaptation |
|
|
On a flower, which part is usually the colorful part, and which is the male part? |
Petals and stamens |
|
|
What is the cause of most spontaneous miscarriages in pregnancies? |
Serious genetic mutations |
|
|
Darwin's finches supported the ides of evolution because |
They were clearly all finches but they had adapted |
|
|
Why is it likely that a corporation will want to patent a genetically engineered product? |
It costs a lot to genetically engineer a product and the company will want to share is as much as possible to make a profit. |
|
|
What is the goal of stem cell research? |
To be able to grow human stem cells to replace damaged or diseased cells |
|
|
In the early 1900s, many states passes eugenics law in order to prevent biologically defective people from having children. What was their goal in doing this? |
To improve the "human stock" |
|

|
What is one reason evolution is less well accepted in the United States than most other countries? |
Evolution. Has become highly politicized in the United States |

|
Which of the following g are potential problems with germ-line gene therapy? |
All of the above |
|
|
What is one way scientists determine how closely related one organism is to another? |
By comparing their DNA |
|
|
The Modern Synthesis refers to our current understanding of how evolution by natural selection works. Darwin couldn't explain it at the time he was working on the idea. What was he missing? |
He didn't understand how the inheritance of genes provides the necessary variation. |
