I believe D because if the fertilizer had a concentrated source of nitrate (which plants do need) then when watering that can go into the ground water which is underground <span />

A forest is home to a large population of flies with high genetic diversity. A nearby factory has
sukhopar [10]

Answer:

Genetic diversity can increase the chance of the flies population to be better adapted or resistant to the pollution. See explanation below

Explanation:

Genetic diversity refers to variation among the genes contained in a particular species of organisms. Genetic diversity occurs during production of gametes (meiosis) in sexual reproductive organisms. According to the question, a forest is home to a population of flies with high genetic diversity.

Genetic diversity will help the fly population survive an exposure to pollution from a factory by increasing their adaptation to the pollution. It is very likely that some of the fly population will contain allelic variation that will help them resist the effect of the pollution in the forest. The surviving flies will produce offsprings that will carry the set of resistant genes.

What impacts do you think the burmese pythons might have on local ecosystem
Zigmanuir [339]
Introduction of burmese pythons to a local ecosystem can have grave consequences, as has been proven in Florida. Burmese pythons are skilled predators, and they are not easily killed by other animals. If introduced to a climate they can thrive in, they will start hunting local animals. With little to no predators capable of killing them, they will flourish because of plentiful food supply, and they will continue to increase in number. They will decrease the level of animals directly below them in the food chain, which will then increase the number of animals and plants that had previously been eaten by the python's new food. 

Basically, don't mess with food chains! :)

daser333 [38]
 <span>1. Biological disadvantages; people will be able to rid themselves of diseases or provide themselves with superior genes. 

2. People will want to make clones; people will want to provide themselves, or their children, with superior genes; superior genetic people will create a higher, genetically-modified class.</span>

1.The turgidity pressure direction in the plant cell is antagonized by the effect of
aleksklad [387]

1. The turgidity pressure direction in the plant cell is antagonized by the effect of <u>sap vacuole</u>. Option b is the correct answer.

2. The answer choice above which do not true evidence that the physiological support is a temporary support is:

The deposition of cellulose or lignin in different plant parts

Option c is the correct answer

3. The gaining of the plant cells to the physiological support is accompanied by:

The increase in the concentration of the solution inside the sap vacuole.

Option D is the correct answer

4. In any of these cases the physiological & structural support present together is

The deposition of cutin on the walls of epidermis of spiny fig. Option b

5. The relation between the width of the skull sutures & the age of man is:

No relation between them. Option D

<h3>What is cell?</h3>

Cell is the simplest, structural, functional and functional unit of life.

There are two types of organisms based on the number of cells they possess. They are:

  • Unicellular organisms
  • Multicellular organisms

So therefore, the turgidity pressure direction in the plant cell is antagonized by the effect of sap vacuole
