Mitochondria are cell structures that contain a small quantity of DNA.
Scientists are sequencing the DNA of one particular gene in mitochondria to
help identify different species of many animals including myriapods. The
sequences that they find are called ‘barcodes’.
(i) State the part of the cell that contains most of the DNA.
[1]
(ii) Suggest how DNA barcoding might be useful in the classification of animals,
such as myriapods.

Answers

Answer 1
The part of the cell that contains most of the DNA is the mitochondria.
The use of the DNA barcoding is that by comparison with a reference library such as DNA sections an individual sequence can be used to uniquely identify an organism to a species just like how a supermarket scanner uses the black stripes of the UPC barcode to identify an item

As chemical energy is released from the bonds in the monosaccharide, it is harnessed to synthesize high-energy adenosine triphosphate (ATP) molecules. ATP is the primary energy currency of all cells.

Read the passage. Then explain the ways humans have influenced the traits in corn plants and the impacts each biotechnology has had.

Passage
Many of the types of corn found in grocery stores were originally bred for their taste and productivity. But these varieties are often threatened by pests. This makes it harder for farmers to produce enough corn.
Scientists have used genetic engineering to make GMO corn plants that are resistant to pests. In one type of GMO plant, they added genes from bacteria that live in soil. The genes let the GMO plants produce a bacterial protein that kills certain insects.

Answers

Answer:

It decreases cost of production on the crop as well as increase production.

Explanation:

It is a very efficient method to save a corn plant from the attack of bacteria. This method is used in almost each and every plant in order to make it resistance against harmful pests and microorganism. By using this technology, the cost of production on the growing of crop decreases which gives more profit to the farmers as well increase the overall productivity of that corn crop.

Answer:

One of the ways we have influenced the traits in corn is through selective breeding. We now have taller plants, and bigger ears of corn, that taste better. Another way we have influenced the traits is by modifying them to be pest resistant.

Answers

It needs to be revisited because of the random acts of violence that it enables.

Explanation:

People that have access to weapons of mass destruction use them to kill people for no reason. For example, the sandy hook shooting, the recent Stoneman Douglas shooting, and the Christchurch shooting. All these shootings could have been prevented if there was stronger gun control. If people did not have access to automatic firing machine guns, less people would have died.

Answer:

Biotechnology is a branch of science that deals with technology by utilizes biological systems, living organisms, or parts of this to develop or create products with the goal of human welfare.

During brewing and baking bread yeast are used to produce alcohol are examples of processes that fall within the concept of biotechnology, Genetically modified orgnisms and crops are also product of the biotechnology. The insulin production also an example of this process.

People consider use of biotechnology unethical to produce genetically modified organisms or crops and cloning is considered as against the law of nature.

C. The question may need to be "should we" manipulate genes of organisms instead of "can we".
D. Creating plants with new genes may trigger allergic reactions

Answers

Answer:

The Answer Is A.

Explanation:

If They Can Be Used For Cleaning Up Mining Waste And For Sewage Treatment, That Makes Them A Good Thing. So It Wouldn't Be A Concern. Hope This Helps.

Genetically engineered bacteria cells can be used to clean up mining waste and for sewage treatment, which is not an ethical concern raised by genetic engineering. So, the correct option is A.

What do you mean by Genetic engineering?

Genetic engineering may be defined as a process that involves the manipulation of the genetic material of organisms with help of lab-based technologies.

Bacterial species produced by genetic engineering used in cleaning up mining waste and sewage treatment benefit the atmosphere by reducing the level of waste and toxic compounds from suuroundings. So, it is not a matter of ethical concern.

Therefore, the correct option for this question is A.
