One of the newest applications of cell technology is called cybrid embryos. This process involves replacing the nuclear material of an animal cell with human nuclear material. How might this process affect public policies about research by using stem cells?

Answers

Answer 1

Answer: In this type of research, human nuclear materials are used therefore it shall apply the same policies and concerns about the use of human embryonic stem cells (hESC).

Many scientists are frustrated because their work has been at a standstill due to laws about stem cell research. Some of these laws ban the use of such application like the Dickey Amendment.

Answer 2

Answer:

Answer: A. The same policies and concerns about the use of human embryonic stem cells would most likely apply.

Explanation:

The building blocks of proteins are known as amino acids. These acids are not only the building blocks of proteins--they are also important in many other chemical and biological processes.

The answer is amino acids

Light from distant galaxies most likely show

Answers

Light from distant galaxies can help us calculate how old the galaxies are. By analyzing how the how the light has changed by the time it reached us, we can find out how old the star system from which it originates is.

In one or two sentences, summarize the technique of gel electrophoresis.

Answers

Gel Electrophoresis is the technique for sorting DNA molecules based on their number of base pairs by running a current through the gel. The sample travels opposite of the direction of the electrical charge since DNA is negatively charged. Using a certain primer you can identify the BP of the sample.

its the seperation of different lengths in a sample by using dna is negative charged

Why is preventing pollution at its source the first strategy in minimizing environmental risk?a.

It is easier and more effective to prevent pollution than to clean up and dispose of waste.
b.

Remediation of contamination is easier than pollution prevention.
c.

Habitat restoration cannot be undertaken with modern technologies.
d.

Safe waste disposal is the easiest was to minimize environmental risk.

Answers

The control of pollution is key to minimize environmentalrisk due it is easier and more effective to prevent pollution than to clean up and dispose of waste (option A).

What is pollution?

Pollution refers to the contamination of water, air (atmosphere), and soils with nocive substances that may be harmful to the environment.

Pollution may also be harmful to human health, as well as to life in the surrounding ecosystems (either aquatic or terrestrial ecosystems).

Pollution may significantly alter the delicate internal equilibrium (homeostasis) of the whole ecosystem.

In conclusion, it is easier and more effective to prevent pollution than to clean up and dispose of waste (option A).

The correct answer for this question is a) It is easier and more effective to prevent pollution than to clean up and dispose of waste.

Yes, it is more effective way to control environmental risk by preventing pollution at its source. First it help us to control the flow of toxicity through water and air. It is often more difficult and expensive to control pollution after it has been released into the environment so it will also help us to cut the cost of treatment of pollutants

Which of the five factors that can lead to evolution would operate on a change in body color that enabled animals to better hide from predators?A. natural selection
B. genetic drift
C. sexual selection
D. gene flow

Answers

Adaptive evolution means evolutionary changes in an organism that make it suitable for its habitat. Natural selection is the factor that can lead to evolution for change in body color that enabled animals to better hide from predators.

What is the process of adaptive evolution?

A genetic trait that helps organisms to increase their reproductive success are adaptive traits. It is a type of natural selection.

Adaptive evolution can be done by following process:

Selecting beneficial alleles.
Increasing their frequency.
Selecting deleterious alleles.
Decreasing their frequency.

Thus,the correct option is A.

What happen to the protein that passes through the cisternae of the golgi?

Answers

Answer:

Proteins are processed and modified in a successive manner to add or remove sugar as they move from cisterna to cisterna.

Explanation:

Golgi apparatus has a flat membrane disk in varies in number in stack, the number can be in between 3 to 20, however six is found in most of them. Cisternae can be separated in four classes cis, medial, trans, and TGN.

Proteins that come from the endoplasmic reticulum in cis type of cisternae after passed through cis to cis and move the protein in order to add or remove sugars to protein.

Thus, the correct answer is - Proteins are processed and modified in a successive manner to add or remove sugar as they move from cisterna to cisterna.
