Diffusion is the spontaneous movement of a substance from an area of _____ concentration to an area of _____ concentration. Options are lower, similar, and higher for both

Answers

Diffusion is the spontaneous movement of a substance from an area of higher concentration to an area of lower concentration.

What is the diffusion ?

Diffusion refers to separate the particles of some solution, that get the concentration differences in the process.

This is because of the spontaneous motion of the molecules.

So, diffusion refers to separate the particles of some solution, that get the concentration differences in the process.

What is the difference between a species and population

Answers

Species are all of one type...like Canis familiaris. A population is a group of the same species, like a pack of Canis familiaris. A community, however, would include all Canis whateveris, plus all the other different species. A community lives in the woods...all the different plants and animals.

This is a good question, I feel that a species can only consist of a specific type of organism. Example "dogs" and "wolves" species name is canus lupus and a dog's is canus familiarus. A population can consist of multiple species.

Scientists have changed the DNA of a type of cabbage so that it contains a tiny amount of poison from a scorpion’s tail. The poison in the cabbage kills caterpillars that try to eat it. What kind fo example has been exhibit? A). gene therapy B). selective breeding C). genetic engineering D). artificial selection

Answers

I think the correct answer from the choices listed above is option C. This certain occurrence is an example of genetic engineering. In this case, the genetic makeup of the cabbage is being altered in order to improvements to the plant for its survival. Hope this answers the question.

The correct answer is option C

Genetic engineering is the branch of science that deals with manipulation in the genes. The cutting and joining of two different types of DNA segment to get the desired character is also an outcome of genetic engineering.

Here, the gene coding for the poison in scorpion is cut and joined in the DNA of cabbage to produce small amount of toxin. This toxin will kill the caterpillar feeding on the cabbage.

This is an example of genetic engineering.
