Could there be some kind of molecular editing system ? What tools could be devised to work with genes? Could scientists then create tailored DNA molecules

Answers

yes. there already is, scientists can genetically modify plants by adding or removing genes to make them different such as make a corn stalk have 4 ears instead of 2. but also breeding like dogs and other animals is a form of molecular editing because they essentially cause a gene mutation that alters the gene sequence and created a tailored DNA molecule. like a golden doodle dog is a genetic modification of a golden retriever and a poodle it wasn’t a natural combination to begin with if you want to get into technicality’s all domesticated animals are genetically modified. BUT the plant example about GMO plants& foods is probably the best example. they can also make plant that have pesticides in their dna so they don’t have to spray them but they’re super toxic to humans and animals that eat them.

What characteristic of viruses distinguishes them from cells?

Answers

Answer: Viruses, although not living things, do show some characteristics that they are living. Because they can't reproduce by themselves (without a host), viruses are not considered living. They are made of proteins and glycoproteins like cells are. They contain genetic information needed to produce more viruses in the form of DNA or RNA.

They are acellular, that is, they contain no cytoplasm or cellular organelles. They carry out no metabolism on their own and must replicate using the host cell's metabolic machinery.

Click on "Embankment dam at a gold mine." Of the two opinions to consider in this case, which one presents a stronger argument? How does that help you make your final decision as the consulting dam engineer? What was your decision for this dam, as the consultant? How can you accomplish this and still stay within your budget? (Site 1)

Answers

Answer:  The strongest argument is the one that refers to security of people. This helps me to make a final decision, to ensure that there will be no accidents and guarantee that the mine will be used to generate moeny. So my decision is to repair it but choose to repair only the most urgent parts, to still stay within the budget.

Explanation:

A gold mine is a place where gold is extracted from the ground. Because of its value, the extraction of gold generates economic and social benefits all over the world, which has made this activity one of the most important in the world. There are also many ways of extracting this mineral.

The best argument will be the one that indicates the greatest concern for the safety of the citizens of that city or town. If there is a dam, it should be repaired in the best possible way. This will ensure the safety of the town and guarantee that the mine continues to be used, to generate economic benefits. Then, if the gold mine continues to be used even if it is not productive as it was, it must be repaired. However, in order not to make large expenditures and have a low budget for repair, I can choose to repair only the most urgent or necessary part.

So, the strongest argument is the one that refers to security of people. This helps me to make a final decision, to ensure that there will be no accidents and guarantee that the mine will be used to generate money. So my decision is to repair it but choose to repair only the most urgent parts, to still stay within the budget.

Why flower produces only a small amount of nectar (food for insects) at a time ​

Answers

Answer:

Nectaries are usually located at the base of the flower stamens, which draw animal visitors into contact with the pollen to be transferred. Most flowers secrete only relatively small amounts of nectar, which encourages cross-pollination, since animals must visit several flowers in order to receive a full meal.

Symbiosis is the type of relationship or interaction between two different living organisms that share a similar kind of habitat. This is of three types including mutualism, commensalism, and parasitism.

What is Symbiosis?

Symbiosis can be defined as a type of relationship or interaction between two different living organisms which share a similar habitat. There are three different types of behaviors that were observed in symbiotic relationships, namely mutualism, commensalism, and parasitism.

In this type of interaction, the organisms live in a close physical association with each other. In the case of symbiosis, both the organisms are benefitted from the interaction. This type of interaction provides an advantage to both the organisms. The common example of symbiosis is the Rhizobium bacterium species and the leguminous plants.

Which of the following is released from ATP and therefore provides “energy”?
A) water
B) Pi
C) glucose
D) ADP and Pi
E) ADP only

Answers

Waterrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr

Pi or inorganic phosphate is released from ATP and therefore provides energy.

What is ATP?

It is the energy-carrying molecule found in the cells of all the living things. It is a nucleotide, which comprises three main parts, that is,

The nitrogenous baseAdenineRibose sugarA chain of three phosphate groups combined to ribose

The tail of phosphate is the actual source of energy, which is tapped by the cell. The accessible energy is present within the bonds between the phosphates and is discharged when the bonds are dissociated. It takes place via the supplementation of a water molecule, the process known as hydrolysis.

Generally, only the outer phosphate is withdrawn from the ATP to produce energy, when this takes place ATP get transformed to ADP or adenosine diphosphate.

Thus, the correct answer is option B, that is, Pi.

C. sugar molecules move into a cell.
D. molecules move from areas of greater concentration to areas of lesser

Answers

Answer:

d

Explanation:

The process of diffusion occurs when molecules move from areas of greater concentration to areas of lesser concentration. The correct option is D.

What is diffusion?

The movement of essential, small molecules across the cell membrane as well as the movement of materials within cells both depend on the process of diffusion.

The exchange of gases in the lungs and gills is regulated by this process. As a byproduct of biological metabolism, carbon dioxide is released by all cells.

For example, when you pour a red color drop into the water, slowly the color molecules are evenly distributed in the whole water. It does not need any energy because it works according to the concentration gradient.

Thus, the correct option is D. molecules move from areas of greater concentration to areas of lesser concentration.
