Which is the best explaination for how chemical energy is transferred with cells

Answers

Answer:

Inside the cell, each sugar molecule is broken down through a complex series of chemical reactions. 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.

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.

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.

Hope this helps! ✌️

Which of the following is NOT an ethical concern raised by genetic engineering?
A. Genetically engineered bacteria cells can be used to clean up mining waste and for sewage treatment
B. Creating organisms that are not naturally occurring may disrupt the environment
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.
